Passing the Baton (or Ball)

The dog days of summer are in full flush in Dallas as I compose this editorial, and the curtains have just come down on a most exciting edition of World Cup soccer as well. And I get to write about the third most favorite thing in my life after chemistry and music: namely, sports. There is nothing more exquisite than a perfectly thrown Tom Brady touchdown in football (i.e., the American variety!), an inside-out forehand from Roger Federer, a Lionel Messi move in soccer, or a Kobe Bryant no-look, behindthe-back pass on the hoops floor. Similarly, seamless transfer of the baton in a relay race is satisfying to all involved. Sports teaches you about life as well, the ability to face success or failure with equanimity. On this topic, Rudyard Kipling famously wrote: “If you can meet with Triumph and Disaster / And treat those two impostors just the same.”1 (I urge you to read the full poem, titled “If—.”)

I am now passing the editorial baton to the new editor of Interface, Rob Kelly. It was most pleasing to see Rob taking the reins, as I have known him a long time, also from his role as a representative of the ECS Corrosion Division on the Interface Advisory Board. I have little doubt that Rob will run with the ball and take the magazine to new heights. He has the right combination of insightfulness, vision, and humor to handle whatever editorial challenges are hurled in his direction. This includes recalcitrant authors and guest editors.

I recall Mary Yess, the erstwhile managing editor of Interface, cautioning me when I first took over the editorial duties back in 1999. She advised me to put away my tennis racket and the guitar to focus on the more urgent tasks at hand with this magazine. I will echo similar words to you, Rob; please put away those golf clubs for a while. You will not have time to improve your handicap any time soon. And stay tuned.

https://orcid.org/0000-0003-4917-7790

Most importantly, Raj—on behalf of the entire ECS— thank you for your stewardship of this great baton. Your contributions will always be part of its DNA. You have left large shoes to fill, but I will do my best to follow the Hippocratic Oath, or as my father often said, “Ok, Rob, try not to screw this up.” With both hands firmly on the baton, I will run as fast as I can until it is my turn to pass the baton to the next runner.

It is an exciting time for Interface. Its evolution will continue with the help of the Interface Advisory Board (IAB), the ECS staff, and ECS members, but its bedrock purposes will remain. Its first goal is to make the work of each topical interest area (TIA) accessible to members in other TIAs as well as to scientists in other disciplines who read these articles. Showcasing the importance of the work of ECS members to the general public is of increasing importance. Finally, its role as the historical record of the Society is important to honor those who have made ECS what it is, and as a reminder to all of what is expected of the caretakers of that baton. I will keep you in suspense about the details of our nefarious plans, but hints may be found in my answers to the Five Questions in the summer 2018 issue of this magazine. That said, I look forward to my first meeting with the IAB in Cancun (I know, rough duty), as well as any and all feedback from you, the readers. I am very much looking forward to running this portion of the race. Excuse me while I go carefully stretch out my hamstrings; they have been dormant for a long time.

Once in a Lifetime

In the summer of 2009, less than a year into my time with my previous employer, IEEE, my then boss suggested I attend a meeting of an organization with which we cosponsored several technical journals. Being new to both working for a technical society and living in the state of New Jersey, I was familiar with neither the organization hosting the meeting nor the town in which it was located. But I was eager to learn all I could about my new role, and my new home state, so I agreed to attend.

Although I cannot recall specific details about that meeting, I do clearly remember how I felt after it was over. As I walked back to my car, I called my wife, Liz, and told her how impressed I was with the organization and the people working there. Even the office building, with its homely feel and comfortable, wooden library-style meeting room, appealed to me.

“I could really see myself working here,” I said.

Over the years, Liz has heard me muse about a lot of things I could see myself doing career-wise, so she did not put a lot of stock in my comment. To a certain extent neither did I—after all, I had only recently started my position with IEEE and was extremely excited about the prospects my new job held, but I never forgot about that meeting, or the people I met that day.

As you may have surmised by now, that fateful meeting I mentioned took place at ECS. The people I met with were Annie Goedkoop and Mary Yess, long-standing members of the team I so proudly joined on July 19. What an amazing thing to ponder as I sit at my desk, on day three of my new job, writing the first of (hopefully) many Pennington Corners!

When I consider the serendipity of events that led to my joining ECS, from my long-ago interest in the Society, to the alignment of my relevant skills and experience, to my strong belief in the mission of ECS and the Free the Science initiative, this is truly a once-in-a-life-time opportunity for me and one to which I am inspired to fully commit my time, talent, and resources. However, this is also bittersweet for me, for as

excited as I am to be in my new role, I will sincerely miss the opportunity to work more closely with Roque Calvo. Being his successor is as much an honor as it is a daunting task. Though I know that if I am even half as successful as Roque has been during his tenure with the Society, I will have done a great service for ECS, its members, and the community at large.

Over the coming weeks and months, my plan is to immerse myself in all I can about ECS, to develop a deep understanding of our operations and strategic plan, and to work with the volunteer leaders and senior staff to chart our future directions. Granted, there is quite a lot of work ahead of us, and we face challenges on many fronts. However, with the insightful leadership of ECS President Yue Kuo and the rest of our outstanding volunteers, coupled with the multifaceted capabilities of the Society’s professional corps, I have every confidence that together we will be successful at maintaining and advancing ECS’s preeminence in the field of electrochemical and solid state engineering.

In closing let me say what an incredible privilege it is to serve as executive director of this remarkable organization. I look forward to working closely with each and every one of you. Anytime you have questions, comments, or just want to reach out, please do! I would love to hear from you at Chris.Jannuzzi@electrochem.org.

Thanks and all the best!

ECS Appoints New Executive Director/CEO

Last year, ECS leadership set about the herculean task of finding a successor to Roque Calvo, who served as a steward of the Society for over 37 years, directing its course through periods of immense change while vastly expanding its efforts to advance electrochemical and solid state science and technology.

Now, after an intensive candidate search that spanned months of consultations, interviews, and conferences, the Society is pleased to announce that it has found its new executive director and chief executive officer in Christopher J. Jannuzzi, former executive director of two IEEE societies: the Electron Devices Society and the Photonics Society

Jannuzzi demonstrates extensive experience in all aspects of the operations of scientific societies, coupled with strategic foresight and a propulsive passion for ECS’s mission.

Prior to joining IEEE, Jannuzzi was a senior director at the College Board in New York. He received his undergraduate degree from New York University and holds an MA in organization and leadership from Teacher’s College, Columbia University. Jannuzzi lives in Shrewsbury, NJ, with his wife, Elizabeth, and their children, Michael, Raymond, and Julia.

Selecting a Candidate

The Society’s search for a new executive director and chief executive officer was conducted by a committee chaired by ECS Secretary James Fenton and consisted of past ECS presidents Larry Faulkner, Fernando Garzon, Dennis Hess, and Esther Takeuchi. With the assistance of a search firm, the committee carried out a thorough and inclusive evaluation and interview process, speaking with staff, division leaders, past presidents, and others to obtain input to guide their candidate search.

Drawing from this input, the search committee determined that the new executive director’s priorities should be to (1) expand ECS’s reach and global presence, (2) lead and organize ECS staff, (3) evaluate ECS’s financial model, (4) develop new external partnerships, and (5) strengthen governance and board relations.

“Through my work at IEEE, I was very familiar with The Electrochemical Society and had the good fortune to work with ECS staff and volunteers on several joint initiatives over the years,” says Jannuzzi. “I have long admired the Society and am honored by the incredible opportunity to serve as its next executive director.”

The Society is thrilled to welcome Jannuzzi to the position, certain that his insight, energy, and leadership will foster great success for ECS in the years to come.

About Christopher Jannuzzi

Christopher Jannuzzi joined IEEE in 2009 as the executive director of the IEEE Electron Devices Society. In his time with EDS, Jannuzzi launched several key initiatives to ensure the society maintained its preeminence in the device engineering field. From leading efforts to redesign EDS’s digital presence, to leveraging the society’s longstanding connection to the photovoltaic research community to expand IEEE’s standing in the renewable energy space, to developing EDS’s robust webinar program, he helped revitalize and reenergize the EDS community.

Building on his success with EDS, IEEE expanded Jannuzzi’s role in 2014 to include leadership of the Photonics Society, providing him with the opportunity to have impact on cross-society strategic vision in addition to managing the societies’ day-to-day operations. Among Jannuzzi’s accomplishments with the Photonics Society was the launch of the IEEE Photonics Fund to raise capital for the society’s humanitarian initiatives and to foster diversity within its membership. Launched in 2016, the fund now provides over 100 scholarships and fellowships annually to help students and traditionally underserved communities choose photonics as an educational and career path.

Beyond his work with technical societies, Jannuzzi also helped lead the IEEE Internet Initiative, which raised the institute’s influence and profile in the areas of Internet governance and cybersecurity by providing a consensus of sound technical and scientific knowledge to the technology policy development process.

The committee also concluded from this feedback that the new executive director should possess certain qualifications and personal characteristics relevant to the role, including familiarity with the significance of electrochemistry and solid state sciences as well as the abilities to work with budgets, enhance meetings, understand the scholarly publication process, build relationships with members, fundraise, and sustain commitments to transparency, open communication, diversity, and inclusivity.

Based on these priorities and sought-after qualifications and characteristics, the search committee unanimously chose Jannuzzi as the best candidate for the role. ECS President Yue Kuo then requested a motion to appoint Jannuzzi as the Society’s new executive director, a decision Kuo firmly stands by.

“According to my impression,” Kuo says, “Chris possesses years of invaluable experience managing nonprofit professional societies similar to ECS. His appointment ensures the smooth transition of this highly important position in the Society. We expect that his expertise will further extend the Society’s 116-year history of success.”

Securing the Society’s Future

Jannuzzi bears a wealth of experience that will prove vital to the pursuit of Society objectives throughout the years to come. In addition to having served as the executive director of two IEEE societies, he has successfully managed budgets of approximately $12M. He also has been conducting development work in the technical society domain for a number of years and has secured over $500K in donations.

I have long admired the Society and am honored by the incredible opportunity to serve as its next executive director.
—Chris Jannuzzi
By endowing our publications operations through the Free the Science initiative, ECS has aligned how we fund publishing with our core mission to serve the public interest. This is precisely how nonprofits should act and one of the things that excites me most about my new role.
—Chris Jannuzzi

(continued from previous page)

Moreover, Jannuzzi has experience managing staff and working with hundreds of volunteers. He wields a collegial leadership style, interacting with members and volunteers with ease.

“Organizations such as ECS would not, and could not, exist without the dedication of its members and volunteers,” says Jannuzzi. “Therefore, the top priority of the executive director, as I see it, is to operationalize the vision of the Society’s elected leadership. ECS is blessed with a talented staff and a dedicated corps of world-class scientists and engineers to drive the organization forward.”

James Fenton, chair of the search committee, was struck by Jannuzzi’s drive to enhance collaborations between the Society’s staff, members, and volunteers.

“I feel Chris was impressed with the passion that the members felt for the Society and the family nature of the Society,” Fenton says. “Chris also has that passion and is looking forward to help lead the Society into an ever-changing future. Chris was impressed with the way ECS ‘punches above its weight class.’”

“When one considers the depth and breadth of all that ECS does—from conferences and publications, to education, awards, and member engagement, it is the staff-volunteer partnership that makes it all possible,” says Jannuzzi. “As executive director, my responsibility is to ensure that partnership continues to flourish.”

Jannuzzi was also chosen for his extensive experience in the scholarly publishing arena. IEEE has a $200M publishing enterprise; hence, Jannuzzi is quite familiar with the strains being placed upon scientific publishing. He is familiar with ECS publishing, having worked on publishing initiatives with the Society in the past, and is a staunch proponent of the Free the Science initiative.

“One of the things that most attracted me to ECS was Free the Science,” Jannuzzi says. “I have worked for many years in scientific publishing and seen firsthand the upheavals open access mandates are having on technical societies that rely on subscription-based revenue to survive. But by endowing our publications operations through the Free the Science initiative, ECS has aligned how we fund publishing with our core mission to serve the public interest. This is precisely how nonprofits should act and one of the things that excites me most about my new role.”

Jannuzzi’s appointment renders ECS optimistic for the Society’s future—for all the ways it will grow and thrive under his leadership.

“It is quite humbling to follow in the footsteps of such a storied and long-tenured predecessor as Roque Calvo,” says Jannuzzi. “Thankfully, we will have time to work together prior to his departure, so I will be sure to learn all that I can from him. His insight and perspective will be invaluable to me as I transition into my new role.”

Yue Kuo Promotes ECS in Russia and Belarus

During June 2018, ECS President Yue Kuo traveled to three institutes in Russia and Belarus to meet with leading researchers, promote ECS, discuss research, and explore opportunities for future collaborations and conferences.

First, on June 11, Kuo visited the A. N. Frumkin Institute of Physical Chemistry and Electrochemistry of the Russian Academy of Sciences in Moscow, an institute home to many famous electrochemists. There, he attended a get-together hosted by Oleg Batishchev, deputy director of science at the institute, with some Russian members of ECS.

Kuo spoke with individuals who knew V. G. Levich, winner of the ECS Olin Palladium Award in 1973, as well as Vladimir Sergeevich Bagotsky, who was an ECS fellow. Several ECS members attended the meeting, including Tatiana Lastovina of Southern Federal University, who traveled over 1,000 km to meet the Society’s president.

Next, on June 14, Kuo traveled to St. Petersburg to visit the Ioffe Institute, a Russian national laboratory that boasts several Nobel Prize winners and a reputation equivalent to that of Bell Labs or the IBM T. J. Watson Research Laboratory. His visit was hosted by Mikhail Patrov, deputy science secretary of the institute.

While there, Kuo delivered a presentation on ECS’s history and current status to members of the institute. He was given tours of laboratories focused on solid state research and discussed the potential for ECS and the Ioffe Institute to collaborate to organize conferences.

Finally, on June 21, Kuo visited the B. I. Stepanov Institute of Physics of the National Academy of Sciences of Belarus in Minsk. He met with administrative leaders at the institute and gave a presentation on ECS, fielding several questions.

Many individuals Kuo met with expressed interest in collaboration with ECS. Yurii Kurochkin, vice president of the Belarusian Physical Society, entertained the idea of organizing a conference with ECS. Another researcher, an organizer of biannual plasma conferences, voiced potential interest in collaborating with ECS plasma symposium organizers. The leading researcher in the academy’s materials center, who traditionally published papers in European journals, conveyed interested in publishing in the Journal of The Electrochemical Society.

Increasing Influence of ECS Journals: 2017 Impact Factors

The journal impact factors (JIFs) for the ECS journals continue to grow, as evidenced by the data recently released by Clarivate Analytics. For the 2017 reporting year, the ECS journals continue to be among the top-ranked journals. Journal of The Electrochemical Society (JES) is in the top two for Materials Science, Coatings, and Films, and in the top ten for Electrochemistry. The JIFs are published in Journal Citation Reports (JCR), and are just one metric used to gauge the quality of a large number of scholarly journals.

For JES, the JIF rose to 3.662 for 2017 from 3.259 for 2016, an increase of over 12%. The enduring quality and usefulness of the work published in JES is significant: JES has had a cited half-life of greater than 10 years (the highest figure that JCR records) for over eight years. JES is the fourth-most-cited journal in electrochemistry, with nearly 71,000 citations; that same citation count makes JES the second most-cited journal in materials science, coatings, and films. Downloads are another important metric for scholarly journals, and for the ECS journals, there were over 2.4 million downloads for 2017.

For the ECS Journal of Solid State Science and Technology (JSS), the progress is also impressive: over 40% growth in citations for 2017 over 2016. In terms of the JIF, the growth for JSS is striking: the JIF has grown to 1.808 for 2017, from 0.917 in 2013 when JSS was launched—a 97% increase in just four years.

The increasingly influential role that the ECS journals play is due to the Society’s practice of rigorous peer review, which is based on rapid, objective, and insightful feedback, as well as evaluation

for plagiarism. The relevance of the ECS journals is due to the increasing importance of the scientific content covered by the ECS journals: batteries and energy storage, corrosion, fuel cells and energy conversion, sensors, electrochemical engineering, organic and biological electrochemistry, physical and analytical electrochemistry, electrodeposition, nanocarbons, dielectrics, electronics and photonics, luminescence and display materials, and the many subdisciplines within each.

There is a great deal of discussion about the journal impact factors, including the lagging nature of the metric (the JIF looks only at three years of published articles and comes out six months after the end of the prior, or JIF, year). Many researchers, libraries, and funding agencies are debating the validity of the metric, as well as working on developing new ways of evaluating researchers for tenure and promotion.1-3 ECS is a member of the Declaration on Research Assessment (DORA, https://sfdora.org/) which “recognizes the need to improve the ways in which the outputs of scholarly research are evaluated. It is a worldwide initiative covering all scholarly disciplines and all key stakeholders including funders, publishers, professional societies, institutions, and researchers.”

ECS is grateful for the support of its authors, reviewers, editors, and publications staff. These are the people who are responsible for the high standards to which ECS adheres, and which keep the ECS journals growing in impact every year.

ECSarXiv and the Growth of Preprints

Preprints1 are growing at a faster rate than journal articles, according to a recent study from Crossref, a nonprofit organization that makes research outputs easy to find, cite, link, and assess.2 Why are preprints becoming popular? Preprints (on ECSarXiv and most reputable services) are discoverable and have a persistent link to their location on the Internet. (ECSarXiv registers its preprints with Crossref so they receive a DOI.) A preprint can be made available immediately (for ECSarXiv preprints, there’s a

quick moderation step) for grant/hiring committees, and they actually counter scooping by serving to “plant the flag” to claim your research. Preprints enhance visibility, especially for early-career researchers. They’re highly discoverable through Google Scholar, and a growing number of other databases. Preprints can come in many forms: as a classic preprint article (short or long) or even as a slide deck. Presenting your work through a preprint can aid in reproducibility: you can post new, confirmatory, or contradictory results.

Learnings from an Open Science Effort: Virtual Project on the History of ALD

Aalto University, School of Chemical Engineering, Department of Chemical and Metallurgical Engineering, Finland

DOI: 10.1149/osf.io/exyv3

This work summarizes learnings from an Open Science effort “Virtual project on the History of ALD” (VPHA), started in 2013 to clarify the early history of atomic layer deposition (ALD). ALD is a multi-tool of nanotechnology and has been e.g. enabler of the continuation of Moore’s law of transistor scaling. ALD has been

developed historically through two independent routes: atomic layer epitaxy (ALE) and molecular layering (ML). Especially the details on ML have remained little known to a broader audience. In this contribution, learnings in VPHA are seen from the viewpoint of its voluntary coordinator (the author self) related to historical details of ALD as well as from an organizational viewpoint and some other viewpoints. Selected details related to ALD’s history not fully accurately described in three earlier review articles are pointed out. The work made in VPHA has resulted in journal articles, presentations and an exhibition, and VPHA has in part provided the foundation for granting the 2018 Millennium Technology Prize to Dr. Tuomo Suntola. At the time of writing this contribution, in July 2018, VPHA is still on-going, and more volunteers are welcome to join the effort.

Nonlinear Electrochemical Impedance Spectroscopy of Lithium-Ion Batteries: Experimental Approach, Analysis, and Initial Findings

Matthew D. Murbach, Victor Hu, and Daniel T. Schwartz Department of Chemical Engineering & Clean Energy Institute, University of Washington, Seattle, WA, USA

DOI: 10.1149/osf.io/t635x

Nonlinear electrochemical impedance spectroscopy (NLEIS) is a moderate-amplitude extension to linear EIS that provides a sensitive and complementary whole-battery diagnostic for charge transfer kinetics, mass transport, and thermodynamics. We present the first full-frequency, second harmonic NLEIS spectra for lithium-ion batteries using commercially available, 1.5 Ah LiNMC|C cells. The mathematical framework for NLEIS shows, and experiments confirm, that moderate-amplitude input modulations can generate a second harmonic output that does not intrinsically corrupt the linear EIS response. Experimental measurements at varied states-of-charge (SoC) and states-of-health (SoH) are used to illustrate and compare NLEIS and EIS data.

DOI: 10.1149/osf.io/rt29s

Both Si and Ge possess indirect band gaps, which makes them very inefficient light emitters. One way to overcome this limitation is through band gap engineering. In this regard, M. d’Avezac et al. [Phys. Rev. Lett., 108, 027401 (2012)] predicted that a strained SiGe2Si2Ge2SiGen super unit cell on Si0.4Ge0.6 would have a direct and dipole-allowed gap of 0.863 eV, which is ideally suited for optical fiber applications. Here we report on the epitaxial growth of such a structure and its optical properties, for which purpose two similar samples were prepared by molecular beam epitaxy and solid phase epitaxy.

Top panels give AFM images of the MBE sample (left image) and SPE sample (right image). Each full image size is 5×5 µm2. The height scale has been normalized at 20 nm. Bottom panels give the two-dimensional roughness measurements on the full scale images from which the root-meansquare roughness (RMSR) is calculated: MBE sample (left panel) RMSR = 2.07 nm and SPE sample (right panel) RMSR = 0.46 nm. The inset shows a TEM cross-section image of the Si-Ge stacking layers in the SPE sample.

Multiphysics Modeling of Surface Finishing Performance in Pulsed-Waveform Electrochemical Machining

Brian Skinn, Timothy Hall, and E. J. Taylor

Faraday Technology, Inc., Englewood, OH, USA

DOI: 10.1149/osf.io/wybx6

Electrochemical machining (ECM) is a manufacturing technology that allows metal to be precisely removed by electrochemical oxidation and dissolution into an electrolyte solution. ECM is suited for machining parts fabricated from “difficult to cut” materials and/or parts with complicated and intricate geometries. In ECM, the workpiece is the anode and the tool is the cathode in an electrochemical cell; by relative movement of the shaped tool into the workpiece, the mirror image of the tool is “copied” or machined into the workpiece. One notable difficulty with ECM is an inability to predict a priori the tool and process parameters required in order to satisfy the final specifications of the fabricated part. Accordingly, there is potential value in development of a physical phenomenonbased design platform to predict optimal ECM tool shape. Such a capability is anticipated to dramatically shorten the process/tooling development cycle.

Using Exotic Materials Like EuD4TEA and MgD4TEA to Monitor Damage and Radiation Exposure in Extreme Environments

DOI: 10.1149/osf.io/94ujn

Space radiation poses a significant challenge to exploration missions to the Moon, Mars, and beyond. As we consider long duration space missions, the risk from radiation exposure increases. There is no simple technique that is capable of real-time radiation detection. Past research shows that the fluorescence yield and decay time are both functions of temperature and radiation fluence. Each of these parameters need to be investigated separately in order to fully understand the physical properties for any useful phosphor.

Once the temperature dependencies are known, then the radiation fluence in the surrounding environment can be estimated. This paper will discuss recent research on europium and magnesium tetrakis dibenzoylmethide triethylammonium (EuD4TEA and MgD4TEA) that could be used to measure radiation and temperature in real time. Both of these organic materials have been shown to be sensitive to proton radiation and to changes in temperature.

The ECS Lecture

Monday, October 1

“Electro- and Photo-Electro-Chemical Generation of the Fenton Reagent. Some Approaches for the Development of Electrochemical Based Advanced Oxidation Processes for Water Treatment”

Luis A. Godínez, Center of Research and Technological Development in Electrochemistry

Luis A. Godínez was born in Mexico City in 1967. After completing a chemical engineering degree and an MSc degree in physical chemistry at the National Autonomous University of Mexico, he moved to the U.S. to pursue graduate studies at the University of Miami, where he obtained a PhD in physical chemistry, and later completed a postdoctoral appointment at the University of South Florida, after which he moved back to Mexico to work as a researcher at the Center of Research and Technological Development in Electrochemistry (CIDETEQ).

The work that will be presented deals with electrochemical advanced oxidation processes that employ electro-Fenton-based reactions to treat wastewater. The explored approach employs packed activated carbon columns as cathode materials for oxygen reduction and iron-loaded resins as the source of the Fenton mixture which produces a powerful oxidant species. Using this approach, novel activated carbon regeneration processes were developed and electrochemical reactors were designed for the removal of persistent contaminants, such as helminth ova in human wastewater. The technology potential of the electro-Fenton approach is important because water management is particularly complicated in a country like Mexico, in which there are serious problems for water accessibility as well as industry-related pollution.

DATA SCIENCE SHOW CASE Cancun, Mexico

ECS Data Science Showcase

The ECS Data Science Showcase will highlight new electrochemical and solid state research and the open source software and datasets that underpin the work. Research talks will be complemented by a demonstration on how others can access, use, modify, and improve the opensource tools and data associated with the research project. The ECS Data Science Showcase is being led by the very capable and engaging team from the University of Washington—Matt Murbach, David Beck, and Dan Schwartz—who have brought you Hack Day (fall 2017) and Hack Week (spring 2018).

Because data science is a fast moving field, the Showcase will conclude with a “Late Breaking News” session to feature emerging electrochemical and solid state research that embraces open software and open data sets. Especially valued are contributions that feature earlystage research where alpha- and beta-testers can be solicited to improve new open research products. The organizers welcome direct email contact by prospective contributors to the Late Breaking News section, up to four weeks prior to the event.

Sociedad Mexicana de Electroquímica (SMEQ)

Due to the interest that the constant meetings of the electrochemical community in Mexico aroused, in 1980 the creation of the Mexican Electrochemistry Society was proposed, in order to group the participants of the meetings and courses. The Society was not legally registered and operated informally for two years, but on April 12, 1983, the Mexican Society of Electrochemistry (SMEQ) was established and has the general objective of promoting, stimulating the development, use and positive transcendence of Science Electrochemistry in the Country and its applications in all branches of Science.

To achieve its aims, it will group all those people, companies, groups and institutions dedicated to the tasks of research, teaching, development and application of the Electrochemistry, exchanging experiences that allow the updating and planned development of this science.

Technical Cosponsors

Sociedad Iberoamericana de Electroquímica (SIBAE)

The Sociedad Iberoamericana de Electroquímica (SIBAE) was founded in 1992 as a corollary of the tenth Ibero-American Meeting of Electrochemistry held in the city of Córdoba (Argentina). The birth of SIBAE finds its roots in the Latin American Meetings of Electrochemistry and Corrosion, which took place between 1972 and 1988 in Argentina, Chile, Venezuela, Brazil, Mexico, and Panama, and which later became the Ibero-American Meeting of Electrochemistry. From 1994 onward, this finally become the SIBAE Congress, which rotates every two years between the member countries of the society. At present, the SIBAE is made up of members from Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico, Peru, Portugal, Spain, Uruguay, and Venezuela.

The goals of SIBAE are to promote cooperation among researchers, students, technicians, and others in the Ibero-American countries; to encourage both fundamental and applied research in electrochemistry; to collaborate with the progress of electrochemistry as a science and as a technology; to contribute to the dissemination of scientific and technological knowledge; and to develop periodic meetings where the official language is the mother tongue of the member countries (Spanish or Portuguese).

Sociedade Brasileira de Eletroquímica e Eletroanalítica

The Sociedade Brasileira de Eletroquímica e Eletroanalítica (Brazilian Society of Electrochemistry and Electroanalytical, or SBEE) was created in 2013 during the XIX Brazilian Symposium of Electrochemistry and Electroanalytical (SIBEE) at Campos do Jordão, São Paulo, Brazil. The main objectives of its creation are to promote the development of electrochemistry and electroanalytical chemistry in Brazil and to provide stimulus for the exchange of ideas, concepts and applications among the members of the electrochemical community. Thus, SBEE is configured as an academic–scientific association that seeks to integrate researchers, research centers, and companies with activities in the area of electrochemistry, electrolysis, and corrosion. On this basis, the SBEE statute was approved and the company was founded in August 2016.

The aims of our society includes the organization of a biennial national symposium, to ensure a forum of excellence for lectures and specialized presentations, the congregation of the electrochemical community, and the facilitation of the establishment and strengthening of cooperation agreements with other societies in the area of electrochemistry. The current president is Artur de Jesus Motheo (2017-2019), who, with the entire board of SBEE, is looking forward to work with SMEQ, ECS and the other technical cosponsors on promoting the AiMES meeting.

Asociación Colombiana de Electroquímica

The Asociación Colombiana de Electroquímica (Colombian Association of Electrochemistry) is made up of professors, researchers, industry professionals, and students interested in increasing the benefits derived from advances in the science and engineering of electrochemistry. The objectives of the Colombian Association of Electrochemistry are:

• To stimulate, on a national level, the research in science and engineering of electrochemistry, and to encourage the wide dissemination of the results derived from it.

Daniel Schwartz Receives Highest U.S. Award for STEM Mentors

Daniel Schwartz, Boeing-Sutter Professor of Chemical Engineering and director of the Clean Energy Institute at the University of Washington, received the Presidential Award for Excellence in Science, Mathematics and Engineering Mentoring from the White House Office of Science and Technology Policy and the National Science Foundation in June 2018. The award recognizes the exceptional efforts of mentors in championing the next generation of innovators in STEM.

An ECS fellow and a lead organizer of ECS Data Sciences Hack Week, Schwartz was honored with the award in recognition of his longstanding commitment to interdisciplinary graduate education, which has helped countless students connect their research to societal and market needs and driven concentrated efforts to recruit and support Native American STEM scholars at UW. Having grown up among the reservations of northern Minnesota, Schwartz witnessed firsthand the barriers faced by tribal students in their pursuit of postsecondary STEM education. Since his 1991 appointment to the faculty of UW, he has worked to make engineering programs more inclusive and accessible while fostering a thriving mentorship network.

memoriam In Memoriam

In 2007 Schwartz launched an NSF-funded interdisciplinary graduate training program that used tribal clean energy research partnerships to draw distinguished Native American students to graduate degree programs offered through UW’s College of the Environment and College of Engineering. In partnership with Washington State University and Salish Kootenai College, and with funding from the U.S. Department of Agriculture, the program has expanded to include a summer research experience program. It also prompted the formation of a tribal student-led start-up company.

As of June 2018, 26 students had earned doctoral degrees through the program. Of the PhDs bestowed, four were awarded to Native Americans, and four were awarded to other underrepresented minorities. Of the six master’s degrees also bestowed, two were awarded to Native Americans.

Schwartz was presented the award in Washington, DC, where he participated in the White House State-Federal STEM Summit, which focused on identifying educational priorities for the nation.

ECS congratulates Schwartz on his achievements and thanks him for all he contributes—to the Society and to the nation—as a proponent of innovation, accessibility, and diversity in STEM.

William M. (Pete) Peterson Jr. passed away at the age of 71 on March 23, 2018, following a brief illness. An eminent figure within the Society, Peterson attended nearly 30 ECS meetings over the years, often serving as an exhibitor—first for Gamry Instruments and later for Ivium Technologies. He was active in the ECS Corrosion Division and the ECS Pittsburgh Section and served on two Society committees: the ECS Sponsorship Committee (2007-2010) and the ECS Finance Committee (2011-2015).

Born in Lyons, Georgia, Peterson received his BS from the University of Georgia and earned his PhD in inorganic chemistry from the University of South Carolina. After finishing his doctoral studies, he completed a postdoctoral fellowship at Tulane University in New Orleans, LA. Peterson began his career at Princeton Applied Research in New Jersey, where he worked as a product manager for 10 years. He then worked in sales and marketing positions for SLM Instruments, Photon Technology International, and IMV before becoming the sales and marketing manager for Gamry Instruments in Warminster, PA, in 1998. Peterson held this position until 2011, when he joined Ivium Technologies, a potentiostat/galvanostat instruments manufacturer based in the Netherlands, as the director of sales and marketing and the manager of the company’s U.S. office in

Fernandina Beach, FL. Peterson retired in 2017, but remained active as an Ivium representative.

Peterson was renowned for his expertise in the fields of electrochemistry and corrosion, as well as his gift for stimulating conversation.

ECS fellow Gerald Frankel and former ECS Corrosion Division secretary Barbara Shaw fondly recall Peterson’s spirited lectures on the operation of a potentiostat.

“For many years Pete attended the Penn State corrosion short course as a representative of Gamry Instruments,” Frankel says. “Each year he gave a lecture on how a potentiostat works. He used the analogy of trying to control the temperature in a shower to be ‘just right.’ In his inimitable style he described how it might start out to be too cold, so you turn up the hot water. And then it is too hot, so you turn up the cold water, and then a little more hot water, but then somebody flushes the toilet (like a sudden current demand) and the system loses control, so you get scalded!”

“He had the ability to take something and describe how it works so that anyone could understand it,” says Shaw.

In his spare time, Peterson enjoyed reading, playing guitar, and spending time with his large family in Fernandina Beach, where he also volunteered at Baptist Medical Center Nassau.

Peterson is survived by his wife, Vicki, his son, William, and his daughter, Jennifer.

Looking at Patent Law: The Leahy-Smith America Invents

Act; Changing from a “First-to-Invent” to a “FirstInventor-to-File” U.S. Patent System and Evolving Standards in Prior Art and Public Disclosure

An important focus of the legislation was the change in U.S. patent law from a “first-to-invent” to a “first-inventor-to-file” patent system. The “first-inventor-to-file” provisions of the AIA went into effect March 16, 2013, while other provisions of the AIA went into effect as early as September 16, 2011, or as late as September 16, 2015.2 In addition, there were subtle but significant changes in the definition of prior art, public disclosures, and grace periods associated with public disclosures. Based on discussions with our colleagues at the recent ECS meeting in Seattle, these changes are particularly relevant with the recent introduction of ECSarXiv and will be discussed herein. An extensive treatise regarding the AIA has been published by the American Intellectual Property Law Association (AIPLA).3

First-Inventor-to-File System

As noted above, a major change resulting from the AIA was the change from the “first-to-invent” to “first-inventor-to-file” U.S. patent system. The rationale behind this change is simply stated from the “sense of Congress” statements in the AIA: it is the sense of Congress that converting the United States patent system from “first-to-invent” to a system of “first-inventor-to-file”4

“will promote the progress of science and the useful arts by securing for limited times to inventors the exclusive rights to their discoveries and provide inventors with greater certainty regarding the scope of protection provided by the grant of exclusive rights to their discoveries.” [emphasis added]

And it is the sense of Congress that converting the United States patent system from “first-to-invent” to a system of “first-inventor-tofile”5

“will improve the United States patent system and promote harmonization of the United States patent system with the patent systems commonly used in nearly all other countries throughout the world with whom the United States conducts trade and

thereby promote greater international uniformity and certainty in the procedures used for securing the exclusive rights of inventors to their discoveries.” [emphasis added]

In summary, the rationale was basically to better define prior art and its impact on patentability as well as consistency with other patent jurisdictions. Regarding harmonization, representatives of five intellectual property jurisdictions (China, U.S., Japan, South Korea, and Europe) meet regularly in an effort to reduce the costs and burden on inventors filing patent applications in multiple jurisdictions. The IP5 collectively prosecute approximately 80% of the world’s patent applications (~2.6 M in 2017).6

Under the pre-AIA U.S. patent system, the patent of the subject invention was awarded to the “first-to-invent.” Recall, an invention is defined by “conception”7 and “reduction to practice.”8 The “inventor(s)” is/are defined as the person/persons involved in “conception.”9 So, the pre-AIA “first-to-invent” U.S. patent system awarded the subject invention to the first inventor to “conceive.” Under the “first-to-invent” system, witnessed notebook references were critical to document the inventors’ contribution to the conception of the invention and the date conception occured. Often, in determining the “first-to-invent,” a costly and time-consuming interference proceeding would be conducted to determine the first inventor to conceive the subject invention. These interference proceedings invoked considerable effort (time and money) in deciding evidentiary matters, since in order to maintain the date of conception the inventor must not have concealed, suppressed, or abandoned the invention and must have exhibited reasonable diligence while proceeding to reduction to practice. 10 These complicated legal concepts were highly case specific and added considerable uncertainty regarding the potential lack of validity of existing patents.

After the AIA, the U.S. patent system is in harmony with most of the world and awards the patent to the “first-inventor-to-file” the subject invention. In Fig. 1, we illustrate the invention timeline where Inventor A is the “first-to-invent” and Inventor B is the “first-inventor-to-file.” Inventor A conceives the invention before Inventor B, but Inventor B files for a patent first. Under AIA U.S. patent law, the earlier conception

In this installment of the “Looking at Patent Law” articles, we discuss some significant changes associated with the Leahy-Smith America Invents Act (AIA).1

of Inventor A is irrelevant, and Inventor B is awarded the patent based on the earlier filing date. The determination of the “first-inventor-tofile” is much more straightforward and does not require interference proceedings in the sense of the pre-AIA “first-to-invent” system. The witnessed notebook references are still important to identify the appropriate contributors to the conception of the invention and hence identify the correct inventors, but witnessed notebooks are no longer relevant to establishing the “first-to-conceive” the subject invention.

Novelty, Prior Art, and Public Disclosure

Recall from an earlier article that for a patent to be allowed and issued, an invention must be novel (or new), which means that it has not been anticipated by and described in publically disclosed prior art.11 Specifically, a person shall be entitled to a patent unless12,13

“(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention; or

(2) the claimed invention was described in a patent … or an application for a patent published …”

If there is publically disclosed prior art relevant to your claimed invention, this may cause a rejection of your patent application, based on a lack of novelty. Novelty rejections are difficult to overcome and the patent applicant generally abandons the patent application or adds limiting elements to the claim to overcome the novelty rejection. Therefore you need to know what publically disclosed prior art is and how it can affect your patent application.

Specific to The Electrochemical Society and its members and contributors, we can identify these “prior art/public disclosures” as activities at ECS meetings, publications in ECS journals, and postings on ECSarXiv. The term “printed publication” seemingly encompasses publications in the Journal of The Electrochemical Society, the ECS Journal of Solid State Science and Technology, ECS Transactions, and ECSarXiv. The term “otherwise publically available” seemingly encompasses poster and oral presentations at ECS meetings. (Note: We will defer an explanation of the prior art terms “on-sale” and “public use” for a future article.)

Any public disclosure of elements of your claimed invention counts as prior art against your claimed invention—no matter the source, method, or type of disclosure. In other words, there is no hierarchy of the importance with regard to publically disclosed prior art. Therefore, we suggest that the same level of care regarding U.S. patent matters should be given to publications in the Journal of The Electrochemical

Society, the ECS Journal of Solid State Science and Technology, ECS Transactions, and ECSarXiv and to posters and oral presentations at ECS meetings.

Please note that an important change with regard to timing of public disclosure of prior art from the pre-AIA system is the term “before the effective filing date” of the claimed invention, in reference to the “firstinventor-to-file” requirement for the AIA statute. The pre-AIA statute used the phrase “before-the-invention-thereof” in reference to the “firstto-invent” statutory requirement.14

Prior Art Requirement

One of the conditions for patentability is the “enablement” requirement for a patent application:15

“The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same.” [emphasis added]

However, for a prior art reference, a lower standard is applied, in that the prior art is only required to describe the invention under the following two basic requirements:16

1. Each and every element of the claimed invention must be disclosed either explicitly or inherently, and the elements must be arranged or combined in the same way as in the claim.17

2. A person of ordinary skill in the art must have been enabled to make the invention without undue experimentation.18

Therefore, while U.S. Patent Application written description must enable one skilled in the art to make and use the full scope of the invention,19 the prior art is only required to enable one skilled in the art to make a single species or embodiment of the claimed invention.20 There is no requirement that prior art meet the “how to” make and requirement of U.S. patent law. This lower standard of enablement is established by case law, which is complicated and evolving, and the reader is encouraged to consult legal counsel as to the specifics of their case.

Description of Prior Art Terms

We will now focus on the terms “patented,” “printed publication,” and “otherwise available to the public” as they relate to “disclosures” in the Journal of The Electrochemical Society, the ECS Journal of Solid State Science and Technology, ECS Transactions, and ECSarXiv and to “disclosures” in poster and oral presentations at ECS meetings. (Note: We will return to “on-sale” and “in public use” prior art in a future column.)

If the claimed invention was “patented” prior to the effective filing date of the subject claimed invention, the patent is prior art as of its issue date or publication of the patent application, whichever is earlier.21 This definition of prior art applies to both U.S. and foreign patents, and the language of which the patent is written is irrelevant from a prior art perspective. In addition, the claimed invention need only be described in a patent but not claimed in the patent. In this case, the patent “describing” the claimed invention is still prior art.

If the claimed invention was described in a “printed publication” prior to the effective filing date of the subject claimed invention, the “printed publication” constitutes prior art if it is “accessible” to the public.22 As derived from case law, the term “printed publication” is a unitary concept and the dichotomy between the words “printed” and “publication” is not valid in view of current technology.23 In the era of document duplication, data storage, and data retrieval, the meaning of “printed” is not the same as when the term was introduced into the patent statute in 1836. Rather, “printed” is more appropriately interpreted as “probability of dissemination” and “publication” is more appropriately interpreted as “publically accessible.” This court noted that a “printed publication” is “publically accessible” if the reference is sufficiently “available” such that one of ordinary skill in the art and exercising reasonable diligence could find the subject reference. Additionally, “electronic publications” are considered to be “printed publications” and constitute prior art provided they “describe” the claimed invention. Consequently, ECS journal publications and postings on ECSarXiv would seem to constitute prior art, even if they were not actually printed, provided they were “publically available” before the effective filing date and providing they “described” the claimed invention.

From above, to qualify as a “printed publication” the reference must have a “probability of dissemination” and be “publically accessible.” For example, a doctoral thesis that is indexed by subject and resides on the shelf of a university library (even with restricted access) is considered a “printed publication” assuming that the fraction of the public (scientific community) concerned with the art could find the reference.24 However, in another case, the doctoral thesis was shelved in a university library, but the indexing was alphabetically by student name and kept in a shoe box in the chemistry department library. In this case, the court reasoned that the thesis was not indexed in a “meaningful” way since the thesis could only be searched using the researcher’s name and the name was in no way related to the subject of the thesis.25 Consequently, the thesis did not constitute a “printed publication”. In addition, an oral presentation at a scientific meeting with written copies distributed to those who requested them was determined to constitute a “printed publication” for the purposes of prior art.26 An ongoing case regarding the question of whether slides and video presented at a technical conference constitute prior art “printed publication” illustrates the case specific intricacies associated with “publically accessible.” (Medtronic, Inc .v. Mark Barry Fed. Cir. June 8, 2018) Consequently, ECS oral presentations posted on ECSarXiv would seem to constitute prior art as a “printed publication” provided they were “publically available” before the effective filing date and providing they “described” the claimed invention. As noted below, even if the oral presentations are not posted on ECSarXiv, they

may constitute prior art relevant to the claimed invention as “otherwise available to the public.”

From the statute, if the claimed invention was “otherwise available to the public” before the effective filing date of the subject claimed invention, it is prior art as of the date it becomes “publically available.”27 This catch-all provision shifts the focus of the prior art inquiry to whether or not the disclosure was available to the public, rather than the means by which the claimed invention became available to the public or what constitutes a “printed publication.” The term “available” is included to describe AIA prior art and may include prior art that was not previously considered prior art under pre-AIA. For example, a poster display or oral presentation (with VuGraphs) at a scientific meeting may constitute prior art provided they “describe” the claimed invention.28 Consequently, poster presentations as well as oral presentations at ECS meetings (even without posting on ECSarXiv or otherwise distributed) would seem to constitute prior art provided they were “publically available” before the effective filing date and providing they “described” the claimed invention.

Prior Art Disclosures by the Inventor and the Grace Period

As noted above, public disclosures of prior art may result in rejection of your claimed invention, due to a lack of novelty. However, AIA U.S. patent law provides grace periods associated with “inventor originated” public disclosures. Specifically, a disclosure made one year or less before the effective filing date of a claimed invention shall not be prior art to the claimed invention if:29

A. the disclosure was made by the inventor or joint inventor or by another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor; or

B. the subject matter disclosed had, … been publicly disclosed by the inventor or a joint inventor or another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor.

An important point here is that public disclosures of prior art may be made not only by you, but also by someone to whom you have described your invention. That colleague’s public disclosure also “sets the clock” for the 12-month grace period, even if they do not inform you of said disclosure. Therefore, caution may be warranted when choosing with whom you share details of your invention, and care taken to prevent undesired and untimely public disclosure.

To summarize, if you (or someone who obtains the subject matter from you) publically discloses your invention, you have one year from the date of disclosure to file for a U.S. Patent, or you will lose your U.S. patent rights. (Note: This grace period generally does not exist in foreign jurisdictions and the loss of rights to foreign patents will generally occur immediately upon public disclosure.) In Fig. 2, we illustrate the invention timeline grace period associated with inventor or inventor originated public disclosure under AIA. Even though Inventor A publically discloses their claimed invention prior to filing a patent application, as long as they file the patent application less than one year after the public disclosure, the patent is issued.

In Fig. 3, we illustrate the invention timeline grace period associated with public disclosure by a colleague of the inventor under AIA. Inventor A privately discloses their claimed invention to their colleague, who subsequently publically discloses details of the claimed invention. This public disclosure sets the beginning of the grace period, and the patent still issues, as long as Inventor A files the patent application less than one year after their colleague’s public disclosure.

Regarding third party disclosures, the grace period only applies to the disclosure of the “same” subject matter obtained from the inventor. However, the grace period for third party disclosures does not apply to “variations” of the subject matter. For example, assume an inventor discloses an invention (eg. a television with and black and white picture tube) to a third party. Subsequently, the third party discloses an invention which includes the original invention but improves, builds on or otherwise modifies it (eg. a television with a color picture tube). Since the disclosure by the third party is not the “same” as the inventor’s

(continued from previous page)

original idea, the disclosure can be prior art against the original inventor’s patent application. In addition, the original inventor cannot use the third party disclosure date to overcome the prior art under the AIA. Under this scenario, an inventor should seek patent protection prior to publication. If an inventor publishes before filing a patent application, the patent application should be filed as soon as possible to avoid the “inventor disclosed third party improvement” scenario.

Disqualification of Prior Art Disclosures

Another way to think about the grace period is that prior art may be disqualified if the disclosure was:30,31

1. one year or less before the effective filing date of the claimed invention; and

2. by the inventor or a joint inventor, or

3. by another who obtained the subject matter directly or indirectly from the inventor or a joint inventor.

If any claim of a patent application (or patent under reexamination) is rejected based on prior art that can be disqualified as described above, the inventor(s) or assignee32 may file a Rule 130 affidavit or declaration to disqualify the reference as prior art.33 The Rule 130 affidavits are of two general forms:34

C. Affidavit or declaration of attribution. [To establish] “that the disclosure was made by the inventor or a joint inventor, or the subject matter disclosed was obtained directly or indirectly from the inventor or a joint inventor.”

D. Affidavit or declaration of prior public disclosure. [To establish] “that the subject matter disclosed had, before such disclosure was made or before such subject matter was effectively filed, been publicly disclosed by the inventor or a joint inventor or another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor … must identify the subject matter publically disclosed and provide the date such subject matter was publically disclosed.”

For an affidavit or declaration to establish “public disclosure” where the disclosed subject matter was a “printed publication,” a copy of the printed publication must be included in the affidavit. If the disclosed subject matter was not a “printed publication”, the affidavit or declaration must provide a detailed description of the publically disclosed subject matter and include appropriate documentation.

Joint Research Agreements

The America Invents Act created further incentive to encourage research collaborations among universities, government, and the private sectors. The patent statute presents three conditions for the disclosed subject matter:35

1. the subject matter disclosed was developed and the claimed invention was made by, or on behalf of, 1 or more parties to a joint research agreement that was in effect on or before the effective filing date of the claimed invention;

2. the claimed invention was made as a result of activities undertaken within the scope of the joint research agreement; and

3. the application for patent for the claimed invention discloses or is amended to disclose the names of the parties to the joint research agreement.

This provision in essence removes patents and patent applications resulting from a joint R&D agreement as prior art against a subsequently filed patent application by either or all of the parties to the joint R&D agreement. Clearly these activities are managed by the research institutions, but we as electrochemical scientists, engineers, and technologists should be aware of them and seek out guidance from the appropriate responsible party at our institutions.

First-Inventor-to-Publically Disclose

In Fig 4, we illustrate the invention timeline where Inventor B is the first to publically disclose and subsequently files a patent application within the one year grace period. Under AIA U.S. patent law, Inventor B is awarded the patent even though Inventor B conceived the invention and filed the patent application after Inventor A. In Fig. 5, we illustrate the invention timeline where Inventor B publically discloses the invention prior to Inventor A. Even though Inventor A files sooner than the one year grace period and is the “first-to-file,” the patent is awarded to Inventor B based on the earlier public disclosure. Consequently, in U.S. patent law, the U.S. may be considered a “first-inventor-to-publicallydisclose” jurisdiction provided the “disclosed” invention is filed at the U.S. Patent and Trademark Office within the one year grace period.

Therefore, the public disclosures in the form of printed publications, public use, on sale, or otherwise available to the public may be used as a “stake in the ground” to provide a one year grace period in which to file a U.S. patent application. (As noted above, you will lose foreign patent rights upon public disclosure.) Consequently, public disclosure in the Journal of The Electrochemical Society, the ECS Journal of Solid State Science and Technology, ECS Transactions, and ECSarXiv, as well as poster and oral presentations at ECS meetings can all satisfy the “firstinventor-to-publically-disclose” grace period associated with AIA U.S. patent law.

However, as noted in the scenario above, public disclosure by the inventor includes risk that a third party inventor will improve upon or modify the disclosed invention and file a patent application before the original inventor files. In this case, the third party inventor’s improved invention acts as prior art against the original inventor’s patent application.

In summary, we have described some of the changes associated with the Leahy-Smith America Invents Act as related to the shift from a “firstto-invent” to a “first-inventor-to-file” U.S. patent system. In addition, we have focused on prior art terms “patented,” “printed publication,” and “otherwise available to the public” as they relate to “public disclosure” activities at ECS meetings, publications in ECS journals, and postings on ECSarXiv. The term “printed publication” seemingly encompasses publications in the Journal of The Electrochemical Society, the ECS Journal of Solid State Science and Technology, ECS Transactions, and ECSarXiv. The term “otherwise publically available” seemingly encompasses poster and oral presentations at ECS meetings. More importantly, we suggest that the same level of care regarding U.S. patent matters should be given to publications in the Journal of The Electrochemical Society, the ECS Journal of Solid State Science and Technology, ECS Transactions, and ECSarXiv and to posters and oral presentations at ECS meetings. In one sense, “public disclosures” may be viewed as a prior art stake-in-the-ground for novelty rejections against subsequent patent applications. In another sense, “public disclosures” may also be viewed as a stake-in-the-ground to provide an inventor a one-year grace period in which to file a U.S. patent application.

An important caveat is that this stake-in-the-ground does not provide

protection from third party disclosed inventions that improve upon the original disclosed invention. Generally speaking, the safest approach is to always file a patent application prior to public disclosure or as soon as possible after public disclosure.

Finally, we have attempted to introduce and provide the reader with an appreciation of the complex issues associated with patent law in general and with the nuances associated with “public disclosures” as prior in particular. With this introduction and appreciation, the reader is better prepared to engage their intellectual property counsel in a meaningful dialog regarding their publications, presentations, and postings. Please understand, the objective of this article is to provide an appreciation of complex patent law matters and is not to replace legal counsel. For specific questions related to patent law matters, the reader is encouraged to consult with legal counsel.

Improving the Electrochemical Performance of Si-Based Anodes via Carbon Coating

Silicon-based nanostructures continue to attract a great deal of attention as anode materials for Li-ion batteries due to their high theoretical capacities. However, the chemical vapor deposition process, which is generally used for the fabrication of pure Si nanostructures, leads to high production costs and can limit scalability. SiO2 is a promising alternative, in terms of ease of production and cost; however, the electrical insulation properties of SiO2 result in sluggish electron transport kinetics and capacity fading issues. Researchers from the Sejong University have recently presented a novel method to prepare carbon-coated SiOx nanocomposites with significantly increased capacities and capacity retention compared to uncoated SiOx samples. The structural stability of the carbon-coated nanocomposite coupled with the electron transport paths provided by the carbon coating resulted in a significant improvement of the electrochemical performance of the SiOx composite. The carbon-coated sample delivered a capacity of ~854 mAh g−1 after the 100th discharge when cycled using an applied specific current of 0.1 A g−1, compared to ~338 mAh g−1 for the uncoated sample. This report offers valuable insight into the benefits of carbon coatings for anode materials.

An Electrochemical Assay Based on Acid-Induced

Dissolution of Nanoparticles to Trigger Enzyme-Free Cleavage for Target Detection

Discovered in 1994, DNAzymes are single strand DNAs that can catalytically cleave their complementary nucleic acids in the presence of their metal-ion cofactors.

Researchers from the Southwest University of China recently reported a sensitive electrochemical assay of thrombin (TB) based on a Zn2+-dependent DNAzyme. The authors first prepared Fe3O4/Au and ZnO/Au nanoparticles and functionalized them with two complimentary single DNA strands, respectively—the one on ZnO/ Au being a TB-binding aptamer (TBA). Mixing the two led to the bioconjugation of the two nanoparticles. After TB was introduced, ZnO/Au was unlinked from Fe3O4/Au because of the TBA/TB binding. Magnetic separation was then applied to isolate the ZnO/Au/TBA/TB. Adding acid caused the release of Zn2+, which was then used to cleave a ferrocene-labeled DNA strand complemented with a Zn2+-dependent DNAzyme immobilized on an electrode. As a result, the ferrocene current decreased and TB could be assayed. Compared with TB, the Zn2+ was easily available with

much higher concentration in this step. The net effect was an effective amplification to the signal of the assay, which showed a detection limit of 8.6 fM and a dynamic range of 0.01 pM to 10 nM.

Electrochemical Atomic Layer Etching of Copper

The increasing use of atomic layer deposition (ALD) for applications in both academia and industry for the layer-by-layer growth of thin films demonstrates the desire for fine control on material deposition. An emerging complementary technique, atomic layer etching (ALE), follows the same principles as ALD but instead focuses on layer-bylayer etching away the top layers. ALE of oxides using plasma-assisted methods are a mature process; however, ALE of metals is still in early development due to the plasma approaches having etch rates higher than 1 nm per cycle which is above that required for atomic-scale control. In a communication by Gong et al., an electrochemical-based ALE approach was developed for atomicscale layer-by-layer etching of copper films. A surface-limited sulfidization was first used to form a copper sulfide monolayer which was then selectively etched using an acid wash without damaging the underlying Cu. Through this method, an etch rate of approximately one copper monolayer per cycle was achieved. Of particular note for this electrochemical ALE process, the RMS roughness of the copper film remains consistent, demonstrating the effectiveness of the technique for conformal etching of the surface.

Graphene Oxide Nanoribbons Incorporated in Carbon Paste Electrodes for Supercapacitors

Though graphene nanoribbons (GNRs) have been widely studied as low-cost electrode materials, its commercialization is still limited by challenges in addressing restacking formation, lower electron mobility and nonreversible structural damages. Considering these problems, a group of researchers from Brazil incorporated graphene oxide nanoribbons (O-GNR) into carbon paste electrodes (CPE) through a modified longitudinal unzipping of MWCNTs method at various concentrations. CPE is a low-cost material with a similar composition to GNR with good electrochemical response that provides an easily renewable surface for electron exchange. The researchers found that the CPE containing 20 weight % O-GNR exhibited good performance, achieving a double layer capacitance of 353, 246, and 178.6 mF cm−2 in 1.0 M solutions of KCl, NaOH, and HCl,

respectively, which are significantly higher than those of the MWCNT electrode. This method overcomes the negative effect of oxygen functionalization as well as provides a higher potential window and eliminates metal impurities. In addition, when electrode surface renewing is established, a longer life time is allowed. Overall, a simple and effective method is reported to improve the accessibility and feasibility of O-GNR electrodes.

Effect of Conditioning Downforce and Pad Break-In Time on Pad Surface Micro-Texture

Chemical mechanical planarization (CMP) has been employed in integrated circuit (IC) manufacturing since the mid 1990s. To achieve consistent wafer-to-wafer results in removal of excess material deposited or grown during the previous step, a newly installed polishing pad first undergoes a breaking-in to establish the initial pad surface micro-texture. Researchers from the USA investigated as a function of time the evolution of the surfaces of two new pads, each subjected to a different downforce of the CVD-coated conditioning disc. Summit height distribution and other metrics were derived from confocal microscopy images of ~4 cm2 samples taken from the pad at 0, 5, 15, 30, and 60 minutes. The pad conditioned at 10 lbf attained stable values of mean summit height and mean summit curvature in 5 to 15 minutes, whereas the pad conditioned at 6 lbf began to approach stable values at 60 minutes of conditioning. In contrast, stable contact density and percentage contact area values were attained for both downforce conditions 15 to 30 minutes into the break-in process, with the magnitudes at the higher downforce twice those at the lower downforce. The authors suggest further experimentation using different conditioners.

A Short Introduction to Sonoelectrochemistry

Istill vividly remember when, in 1994, I received a telephone call from Tim J. Mason (now professor emeritus, Coventry University, England, UK), director of the Coventry University Centre of Excellence for Sonochemistry offering me a PhD position under his and J. Phil Lorimer ’s supervision, in the field of sonoelectrochemistry, the subject of my PhD thesis. I was so excited that the next day I immediately went to the university’s library searching for papers on the subject! To my surprise at the time, there was a dearth of information published on the topic. Needless to say, the application of ultrasound on electrochemical systems is in fact not new—for example, it was first observed in the early 1930s by Moriguchi (1934),1 in the 1950s by Yeager and Hovorka (1953),2 and in the 1960s by Bard (1963).3 To date, over 3,500 publications4 have been published on the subject with the vast majority being published after a review paper in 1990 by Mason et al. from the Coventry group5 entitled “Sonoelectrochemistry,” highlighting the extraordinary effects of sonication in electrochemistry. It is often thought that this review paper was a precursor for reviving the area. Walton et al. (1990),6 Cataldo (1992),7 Yegnaraman and Bharathi (1992),8 Reisse et al. (1993),9 Hagan and Coury (1994),10 Compton et al. (1994),11 Klima et al. (1995),12 Lorimer, Pollet et al. (1996),13 to name but a few, were most probably the first modern researchers to investigate the effects of ultrasound on electrochemical systems; with over 100 papers on the subject published by Compton et al.14 A fairly recent book entitled Power Ultrasound in Electrochemistry: From Versatile Laboratory Tool to Engineering Solution, which I edited in 2012,15 details the effects of ultrasound in electrochemistry (including electroanalysis, corrosion, electrochemistry in environmental applications, organic electrosynthesis, electrodeposition and electropolymerisation), but also the use of sonoelectrochemistry as a tool to investigate cavitation bubble dynamics and flow velocities16 as well as the production of nanomaterials (e.g., fuel cell and electrolyser electrocatalysts) and useful gases (e.g., hydrogen).17-19

So, what is sonoelectrochemistry? No, not SO.NO.ELECTROCHEMISTRY!

It is the study of the combination of ultrasound and electrochemical processes and its applications. This area of research covers various studies from organic syntheses, polymeric materials syntheses, production of nanomaterials, environmental (soil and water) treatments, water disinfection, corrosion of metals, analytical procedures, films, and membrane preparations to the elucidation of electrochemical mechanisms in various conventional and exotic solvents (e.g., room temperature ionic liquids20 and deep eutectic solvents21). It is well-known in the area that the main effects of ultrasound in electrochemistry are the increase in mass transfer and heat transfer induced by extreme solution mixing, a substantial thinning of the diffusion layer thickness (δ) at the electrode surface, a noticeable decrease in overall cell voltage (Vcell) and electrode overpotential (η), and an observable surface modification due to erosion and pitting (Fig. 1). These observations are mainly caused by the implosion of high-energy cavitation bubbles in turn generating high velocity microjets of liquid (up to 200 m.s−1)16

Introduction to Ultrasound and Sonochemistry

Sound frequencies beyond the upper audible limit of human hearing are generally categorized as ultrasound. The frequency range of ultrasound that has been explored for the purpose of processing applications and sonochemistry is in the range of 16 to 3000 kHz.1 In liquid media, the oscillation of pressure waves can give rise to a unique phenomenon, acoustic cavitation.2 During acoustic cavitation, extremely high pressures and temperatures are generated, initiating several physical and chemical effects, such as shock waves, microjetting, micro-streaming, shear forces and the generation of radicals. By implementing these effects individually or together, a wide range of applications such as food processing,3 drug encapsulation and delivery,4 material engineering,5 and electrochemistry6 (Fig. 1) have been developed.

Acoustic Cavitation

Cavitation Bubble Nucleation and Growth

The origin of cavitation bubbles includes two main sources: preexisting gas nuclei and trapped gas residues at the crevices of solid surfaces.10 When ultrasound acts upon these gas nuclei, they grow due to rectified diffusion and bubble coalescence. The coalescence of the bubbles is driven by the primary and secondary Bjerknes forces, where the main driving force for the former is associated directly with the ultrasound wave, whereas the latter one is the acoustic wave radiated by a neighbouring bubble.2 Rectified diffusion growth of bubbles can be explained by the area effect and shell effect theories.2

Oscillation and Collapse of Cavitation Bubbles

The Rayleigh-Plesset equation2 is one of the well-accepted theoretical models for describing bubble dynamics. On the basis of the Rayleigh-Plesset equation, parameters such as fluid compressibility, damping, condensation, and evaporation were included in the theory,

resulting in great enhancement of the theoretical modelling of cavitation bubble dynamics.11 The physical conditions generated on bubble collapse can be derived from the Rayleigh-Plesset equation. For example, Eq. 1 and 2 estimate the maximum temperature (Tmax) and pressure (Pmax) respectively, assuming the collapse is adiabatic.

where pg is the pressure of the gas inside the cavitation bubble, T0 is the solution temperature, p∞ is the hydrostatic/liquid pressure and γ is heat capacity ratio. The estimated localized temperature and pressure can reach up to 5000 K and 150 MPa, respectively.11

Chemical and Physical Effects Generated from Acoustic Cavitation

The primary extreme conditions generated by the cavitation bubble collapse are the extreme pressure and heat, which can lead to further effects from both physical and chemical aspects. The physical effects are closely related to the momentum changes from the bubble oscillation and collapse. The radial fluctuation of the bubbles gives rise to the localized liquid flow surrounding the bubbles, called microstreaming. Upon bubble collapse, two consequent effects can be observed. If a bubble undergoes a symmetric collapse, shock waves with high pressure propagate through the medium, and the pressure void formed at the collapse centre leads to extreme velocity gradient up to the order of 100 m/s at the microscale across the liquid medium. If there is an interface nearby (e.g., solid, immiscible liquid or gas phase), an asymmetric collapse will occur, where a microliquid jet,12 shown in Fig. 2, will form from, penetrating inside of the bubble and hitting interface with high speed and pressure. In addition, the localized temperature change at the collapse centre is not only drastically high, but also fast, where the cooling rates could reach >10 9 K/s.11 Such high cooling rates could lead to unique alteration between amorphous and crystalline forms as well as intermolecular hydrophobic/hydrophilic interactions, such as hydrogen bonds and π- π stacking,13 initiating the potential of highly controllable colloidal engineering.

At the microscale regime, the above-mentioned events can create high turbulence (velocity and heat), facilitating mass transfer, interparticle collision, and modifications of the surface morphology and

interfacial properties. From the bulk perspective, these cumulative physical effects from the localized environment can also generate strong mechanical shear forces, leading to applications such as ultrasonic emulsification, extraction, crystallization, surface modification, and sonogelation, etc.2,13 From the general relationship between the bubble resonance radius and ultrasound frequency shown in Eq. 3, it is clear that with an increase in ultrasound frequency (f) the resonance radius of cavitation bubbles (R) decreases, leading to a less violent bubble collapse. As a consequence, the physical effects discussed above become less significant when the frequency is in the higher range.

Radical generation, on the other hand, is the origin of chemical reactions in ultrasonic systems. In aqueous systems, the extreme heat at the centre of the bubble when bubble collapses could break the OH bond in water molecules, generating hydrogen and hydroxyl radicals, shown in Reaction 1:

HO)))H+OH 2 ii

where, hydrogen radicals and hydroxyl radicals act as the primary reducing and oxidising agents, respectively. (Note: “)))” represents ultrasound.)

The yield of the primary radicals (H• and OH•) in general govern the rate of chemical reactions. The rate of primary radical formation is found to be strongly related to ultrasound frequency and cavitation intensity. In the general frequency range used in sonochemistry applications (20 kHz to 3 MHz), the maximum rate of radical production has been observed in the frequency range 200 to 600 kHz. A lower rate of radical production is generally observed at 20 kHz and above 1 MHz.11 The behaviour of the radical yield can be explained by the combined effects from bubble radius, collapse temperature, bubble population and life time, operating conditions (frequency and power input), and organic additives (sources of secondary radicals), etc.2

Applications of Ultrasound and Sonochemistry

Chemical reactions strongly depend upon mass transfer effects. As per the Arrhenius equation in chemical kinetics, collisions between molecules are important in many chemical reactions. Hence, the mass transfer effects generated by the physical effects of acoustic cavitation have been found useful in several processes (extraction, emulsification, etc.) and chemical reactions. The application of ultrasound technique in several fields including engineering of metallic composites, soft materials, electrochemistry, biomedical, materials, etc., are briefly discussed below, highlighting the crucial roles of chemical and physical effects, individually and combined.

Metal/Metal Oxides Nanostructures Synthesis

The fabrication of metal nanoparticles (MNPs) has drawn significant attention due to their wide applications in the areas such as biosensors, catalysis and optical storage devices. Amongst different fabrication routes, increasing interest has been shown in

sonochemical synthesis of MNPs, highlighting advantages, such as mild reaction environments, fewer reagent requirements and increased reaction kinetics.2

Sonochemical synthesis of MNPs generally involves the reduction of metal ions in aqueous solutions, where instead of externally added reducing reagents, radicals generated during acoustic cavitation act as a reducing agent. An organic additive, such as alcohols, is usually used to generate secondary reducing radicals from primary radicals as shown in Reactions 2 and 3. The reducing radicals can then be used to reduce metal ions to form metal particles (Reaction 4).

A great number of MNPs have been synthesized using sonochemical methods in the past two decades, including copper, iron, cobalt, and noble metals (Au, Ag, Pt, Ru, and Pd).14 Apart from offering easier synthetic routes, sonochemical approach also offers great compositional and structural tuneability for advanced engineering of material architectures.2

For instance, the frequency of ultrasound has been shown to greatly affect the size and shape of Au NPs.15 Amongst the tested frequencies (20, 213, 358, 647, and 1062 kHz), the highest reduction rate of Au(III) was found at 213 kHz, with the smallest size and narrowest size distribution in the presence of 1-propanol, which correlated well with the radical yield trend, where nucleation of the Au NPs will be promoted in a highly reducing environment (i.e., faster kinetics for reaching the critical concentration of nucleation and greater “burstnucleation”). When the radical production rate is low, the nucleation rate is slower than the growth rate of the particles, resulting in larger particles with a wider size distribution.16 The addition of surfactants, on the other hand, could also control the shape of the NPs formed. For instance, the formation of gold nanostructures of different size and shapes is shown in Fig. 3. At an applied frequency of 950 kHz in the absence of any surfactants, Au NPs were formed.17 Au nanorods were produced at 200 kHz in the presence of CTAB (cetyltrimethylammonium bromide), AgNO3 (capping agent), and ascorbic acid (reducing agent).18 Single-crystalline gold nanobelts were formed in the presence of α-D-glucose19 where the role of ultrasound (40 kHz, 100 W) was highlighted in terms of both facilitating inter-particle collision, melting of gold crystals, and the re-orientation of adsorbed α-D-glucose on the gold surface.

Fabrication methods for metal alloys and metal/metal oxide composites have also been developed.20 For example, leveraging the high heat and cooling rates provided by acoustic cavitation, the fabrication of oxides of Zn, Fe, Sn, Pg, Ti, etc. has been reported using ultrasound-assisted methods with great control over the morphology, porosity, and crystallinity,2 which are highly relevant to the areas of gas sensing,21 photocatalysis,22 and electrochemistry.23

Sonogelation

In general, the trigger of a gelation process can be either irreversible crosslinking initiated by the presence of gelators or reversible stimuli such as temperature, pH, and light absorption, etc., which affect the self-assembly and molecular orientations by the inter/intramolecular-hydrophilic/hydrophobic interactions.13 From this point of view, acoustic cavitation can be fitted in both chemical and physical aspects of the gel initiation process. Indeed, a number of studies have reported demonstrating that ultrasound could be used to trigger gelation processes in different solvent systems, forming hydrogels,24 organogels,25,26 and metallogels27 (involving metal-based coordination).

When biopolymers are involved, where both distinct intramolecular structures (e.g., secondary and tertiary structures) and various intermolecular interactions may exist, ultrasound irradiation is capable of altering the interactions from both chemical and physical aspects, causing bond creation, cleavage, and reassembly, which ultimately lead to sol-gel transitions.13 It has been reported that ultrasound irradiation greatly accelerated the secondary structural

change from random coil to β-sheets structures in silk fibroin, which was correlated by the increase in ellipticity at 217 nm in circular dichroism analysis, leading to the formation of the hydrogels (Fig. 4).24

Sonoelectrochemistry

The last two decades have witnessed great developments in the area of sonoelectrochemistry due to the awareness of the benefits provided by interdisciplinary topics.23 Meanwhile, improvements have been continuously reported in the well-developed research areas, such as metal deposition and plating,2 fuel cells,28 and electrodes fabrication29 when combining theories from sonochemistry and electrochemistry. The radicals created by the sonolysis during the bubble collapse provide a “clean” source of reactants that initiate redox reactions, which could vary from polymerization, electrodeposition, degradation of organic compounds, nano-structured material synthesis, enhancement of the performance of electrodes, etc.,2 without introducing harmful external chemicals. In addition, the physical effects of acoustic cavitation could drastically facilitate the reaction kinetics, providing extreme shear, heat and pressure at the centre of the cavitation bubbles, acting as micro-reactors.

Sonoelectrochemistry: Both a Tool for Investigating Mechanisms and for Accelerating Processes

Surface Treatment and Surface Coating

The process of irradiating surfaces with power ultrasound is now widespread, especially in industrial cleaning operations. The principle is very simple: the ultrasonic transducers, vibrating between 20 kHz and up to 400 kHz, are fixed on a tank wall which can contain up to several hundred litres of a solution, in which the ultrasonic wave propagates. In addition to the convective flow generated by the ultrasonic wave absorption, cavitation is induced by the local variation of pressure in the liquid and acts on the contaminants adhering to the metal, plastic, glass, etc. Millions of very tiny bubbles (1 µm to 100 µm), perfectly distributed in the liquid, grow before collapsing violently, penetrating every crevice of the parts requiring cleaning, detaching the stains in a matter of a few seconds.

It is therefore natural to extend this process to the coating process itself, thanks to the increase in mass transfer, due to the agitation induced by convection and cavitation bubble collapse. Moreover, if the bubble collapse occurs in close vicinity of the surface, the surface may either (i) be affected by the ultrasonic shock waves and thus undergo important mechanical effects or (ii) cause a deformation of the bubble and therefore the collapse becomes asymmetric.1 It is interesting to note that the electronic transfer can also be strongly affected by ultrasound, in turns keeping the substrate surface continuously clean by preventing the formation of “parasite” layers able to inhibit important reactions.2 Moreover, the numerous bubbles collapsing at the surface may act as nucleation sites that influence directly nucleation mechanisms, resulting in more random growth.3 Walker et al.4 were the first to report the benefits of ultrasonic irradiation for metallic coating elaboration. Prasad et al.5 showed evidence that several properties may be greatly modified and improved, such as brightness and hardness, better adhesion to substrates, finer grains, a reduced porosity and less internal stress.

The use of ultrasound has also been extended to electroless coating on nonconductive substrates, as for example copper deposition on epoxy resins under high frequency ultrasound.6 Ultrasound not only leads to a considerable increase in the deposition rate, but also in the adhesion (up to 4 N with an increase of almost 40%), whereas the internal stress decreased drastically (down to 50% of the value measured in the coatings obtained under silent conditions). The study of corrosion phenomenon in the presence of ultrasound is an “old challenge,” with the main objective of minimizing the synergetic effect termed corrosion-cavitation frequently observed at industrial scale for fluid circulation (e.g., tube walls, turbine or pump blades, etc.) or on ships’ propellers.7 Various research studies on a large number of substrates (e.g., copper alloys, aluminum, stainless steels, etc.) give strong evidence that ultrasound may increase many types of corrosion. Finally, these results have led to the creation of an international standard (ASTM G32-10)6 allowing the prediction of metals’ behavior in such environments.

A Need for Cavitation Activity Quantification and Characterization

Although power ultrasound offers many advantages at laboratory scale, and thus has attracted a lot of interest since the mid-1990s, only a few cases of “technology transfer” have taken place in industry. This limited translation to practice is due to the lack of fundamental knowledge and data related to ultrasonic systems’ operations. As the intensity of cavitation bubble production modifies drastically the ultrasonic wave propagation and absorption, non-linearity behavior occurs, which in turns prevents the use of simple mechanical laws for accurate reactor modeling.

However, it is possible to use electrochemistry as a tool to study phenomena occurring at an electrode surface and at a given location in a sono-reactor. From a process accelerated by ultrasound, electrochemistry becomes a useful tool to quantify the ultrasonic energy scattered at the immediate electrode surface vicinity. The electro-diffusional method will be of great help, consisting in the measurement of limiting currents during linear sweep voltammetry with quasi-reversible redox couples such as Fe2+/Fe3+ at low active species concentration in solution. This approach has turned out to be extremely efficient for the determination of acoustic intensity at different locations in the sono-reactor.8 By systematically moving an electrode in an ultrasonic field, it is possible to map the acoustic activity, especially the zone close to the transducer where the most intense cavitation activity takes place. Then, to demonstrate the “portability” of our results (i.e., to allow relevant comparisons between experiments performed with different ultrasonic and electrochemical equipment) we proposed to convert the raw electrochemical values into equivalent velocities U, corresponding to normal flows directed toward the electrode surface resulting in the same electrochemical signal than in the presence of ultrasound.9 Subsequent use of the so-called Pollet-Hihn equation,9 makes it possible to obtain a physical quantity characteristic of the ultrasonic activity at each measured point.

Comparisons with “real fluid motion” at a given location become possible thanks to Particle Image Velocimetry (PIV) (measurement using a high-speed camera and a chemical tracer, allowing tracing the displacement into a 2D laser sheet of light). The systematic comparison allows separation of the respective contributions of cavitation events occurring at the electrode surface to the convection flow called ultrasonic wind (Fig. 1).10

The main result is that the range of magnitude of the “real fluid motion” at 20 kHz is about 10 times lower than the calculated equivalent flow. This finding clearly indicates that the main contributor

to the extremely high agitation at the sonicated electrode surface is ca. 90% due to cavitation bubble collapse (including shock waves as well as microjets). A systematic experimental study was gathered together in a phenomenological model and in correlations linking dimensionless Sherwood (representative of agitation) to Reynolds numbers (representing flow) and Schmidt number (representative of the solution electrochemical properties).1

This need for characterization was extended to unconventional solvents such as room temperature ionic liquids. These solutions present physical and chemical properties particularly interesting for numerous applications in electrochemistry (e.g., actinides separation, electrodeposition of metals, etc.).11 Their high viscosities are definitively problematic, but their detrimental effects may be counterbalanced by the strong agitation provided by ultrasound. Thus, the study of the behavior of redox couples adapted to this type of solvents has been undertaken in a micro-sono-reactor designed for this purpose12 (Fig. 2). Depending upon the solvent nature, it was found that the limiting current density (j) decreased in the following order: CH3CN, water, [Bmim] [Tf2N], in good agreement with the variations observed for the electroactive species diffusion coefficient (D). However, while regrouping the electrochemical measurements in Sherwood dimensionless criteria, a single behavior of the [Bmim] [Tf2N] was observed. At similar ultrasonic intensity transmitted to the media (1 W.cm−2), ultrasonic agitation was found to be more efficient in ionic liquids comparatively to water or acetonitrile. Then, the sonoelectrochemical responses of the redox couples in four ionic liquids ([Bmim] [Tf2N], [Omim] [Tf2N], [N1113] [Tf2N], and [Bmpyr] [Tf2N]) as well as in various mixtures of given viscosities (water/PEG, acetonitrile/PEG, and acetonitrile/[Omim] [Tf2N]) were generated and were compared to those obtained under silent conditions at a rotating disc electrode (ω = 5,000 rpm). The data showed that there were two groups of solvents behaving distinctively under sonication: one group for which the interaction “ultrasonic wave/electrolyte” was comparable to that of water only, and another one for which the liquid structuration was different, translated by an eight-fold increase in mass-transfer under ultrasonic conditions.13

This control of the ultrasonic parameters was found to be a major milestone for the design of sono-reactors and their applications. For example, the determination of an “equivalent” tangential equivalent flow was crucial in the design of boats’ hull cleaning tools (Navy Clean company).14 The intense activity of ultrasound on a surface can be used to develop and implement accelerated corrosion tests and to obtain faster responses to corrosion protection level of coatings while complying with the natural corrosion mechanisms and therefore remaining close to natural conditions. Examples of such an application of ultrasound include studies of zinc-coated steels under different electrolytes with the view of reproducing atmospheric conditions15 or on stainless steels.16 For example, the rate of corrosion in 0.5 M Na2SO4 electrolyte is directly proportional to the distribution of the cavitation activity in the sono-reactor (Fig. 3). The figure shows agitation maxima, the positions of which depend upon the ultrasonic frequency and the distance between the electrode and the ultrasonic horn in a “face-to-face” configuration. The position that increases uniform corrosion the most was at a sample-ultrasonic horn distance directly proportional to the quarter of a wavelength, λ/4. By modifying the ultrasonic frequency and the signal amplitude, it becomes possible to modulate the corrosion “intensity.” Alternatively, ultrasound pulses can induce a switch on/switch off effect, corresponding to passivation/depassivation conditions of the 304L stainless steel in sulfuric acid enriched in chlorides.17 In addition, ultrasound has been shown to greatly accelerate the pitting corrosion generated in halide media.16

The use of sonoelectrochemistry in “anodic mode” is very rare for metal treatment, but an increasing number of studies have been carried out in electropolymerisation processes.18 Cavitation bubble collapse seems to be at the origin of a better distribution of nuclei at the surface, and a better solubility of the monomers under ultrasound.18 Thus, coatings with a finer and more homogeneous topography can be obtained as shown in Fig. 4, allowing a high number of applications possibilities where the surface morphology plays a key role (e.g., sensors, corrosion protection etc.).18 Films formed under

a reflective surface), an ultrasonic standing wave is established and gives rise to a cluster of cavitation bubbles that erode the surface. By optimizing all these parameters in collaboration with C & K Components, a reel-to-reel process was designed for the removal of a masking resin,21,22 with a view to obtaining selective deposits. The resin deposited on connectors in continuous scrolling was melted and expelled within a few milliseconds from the chosen zone. The band covered with partially ablated resin underwent an electrolytic coating of precious metals which was selectively deposited on the areas denuded by the HIFU. Finally, this need to control cavitation (i.e., to amplify or completely quench cavitation events) led us to study the frequency modulation of ultrasound.23 This phenomenon uses the ability for the bubbles to oscillate in resonance with the acoustic wave. For a positive frequency sweep (towards high frequencies), the bubbles become too large to resonate in phase with the ultrasonic wave whereas for a negative sweep, a larger number of bubbles can be activated depending upon the sweep rate, opening the doors to an effective control of the acoustic activity in a very wide range.

irradiation are much more compact in texture leading to a reduced mobility of the ions within the films, and the possibility of controlling the movement of the charged species within the organic matrix. It should be noted that the electrical conductivity of organic coatings is slightly reduced under sonication, due to the partial degradation of the polymer chains.19 For example, the conductivity of perchlorate-doped polypyrrole was found to decrease from 0.3 × 104 to 0.2 × 104 S/m. That said, a selective modification of the surface at a strictly delimited zone is also possible with High Intensity Focused Ultrasound (HIFU) transducers, which possess a concave emitting surface that allows the focusing of the high frequency acoustic wave over an area of a few mm2 20 The acoustic intensity generated by this type of technology can exceed the performance of flat transducers, reaching several kW/cm2 with fluid velocity up to 10 cm/s at the focal length. Their integration into electrochemical processes was conducted in conjunction with IMASONIC company (Fig. 5). For polymers layers with acoustic impedance close to that of water, the acoustic energy is converted into heat by viscous friction, at the opposite (i.e.,

Conclusions

With a good knowledge of the cavitation activity mechanisms and of their specific influence on electrochemical processes, it is possible to define the best conditions of the use of power ultrasound in many applications, from accelerated corrosion to cleaning and coating elaboration. This is of considerable importance, by considering both favorable added value/energetic cost ratio and scale-up ability of sonoelectrochemical systems.

Ultrasonic Agitation for Emerging Electrodeposition Systems

Despite the growing importance of electrodeposition for the development of new materials for energy applications,1 sensor fabrication,2 micro and nanofabrication,3,4 the technologies used in these processes remain reliant mostly on traditional methods as rack and barrel plating. In the first half of the twentieth century, agitation in these systems was achieved by cathode movement or air sparging.5 The systematic introduction of eductors,5 the paddle cell and fountain flow for wafer plating,6 and a jet plating system to selectively plate metal at a particular location7 were major innovations of the final quarter of the past century.

While these changes and other academic studies5-12 testify to the importance of agitation during an electrodeposition process, there have been fewer explorations of agitation in the current century. Notwithstanding, over the past two decades there have been new developments in electrodeposition, such as electrochemical printing13,14 and mask-less microfabrication,15,16 which required unconventional agitation schemes as a core need for the process to work. The electrochemical printing method used new jetting technology to deliver fluids, which required precise control over jet placement, fluid viscosity and surface tension.13,14 Electrochemical mask-less microfabrication required that the anode and cathode be placed within 500 μm17 while maintaining good agitation. These developments required new thought for agitating fluids during electrodeposition and understanding them sufficiently to enable the design of new systems. Ionic liquids,18,19 which have been proposed as the next generation of electrolytes for metal deposition, which are highly viscous18,19 and corrosive,20 will also require new approaches for agitation. If conventional methods were used to pump the electrolyte, pump ratings would need to increase by at least one order of magnitude, and pump materials of construction would need to be corrosion proof.

Ultrasonic (US) agitation can provide a way forward for agitation of electrochemical systems.21,22 For example, it is possible that viscous fluids could be displaced using US, thereby eliminating mechanical pumps and contact with corrosive liquids. US agitation using miniature probes could be used to pulsate fluids and through small channels enabling jet flow. For the case where the space between electrodes is constrained, there is the possibility of focusing the flow within the gap. Figure 1 illustrates the last idea: (a) traditional pumping versus (b) US probe focusing flow within the gap.

In this paper we describe the deployment of US to increase agitation in constrained spaces. In particular, here we describe the adaptation and changes needed for measurement of mass transfer rates. The use of US via horns (or probes) as well as tanks for electrodeposition has been described. Specifically the two systems correspond to laboratory scale measurement and industrial scale apparatus. By constrained space we have limited ourselves to a narrow gap between two electrodes; this is generally in the mm scale [23].

Ultrasonic Agitation for Electrodeposition

Ultrasonics has already been used in electrodeposition of metals to improve deposits, current efficiency and improve material distribution.24-26 Enhancement of mass transfer has been detected while studying the effect of US streaming on oxide films27 while others have decoupled mass transfer enhancements caused by US 22,28,29 There have also been attempts to analyse agitation using probes in a face-on29 and side-on systems,30 and mass transfer boundary layer thickness based on these measurements have been quantified.29,30

Here we explain the approach taken by the authors to address an important question: Can US be employed to increase material transport within constrained spaces, i.e., a narrow gap?16,23 At this point, it is unclear to what extent agitation could be improved; furthermore, it was not even evident if experimental techniques, such as the limiting current method, could be applied in these circumstances. In fact, other researchers had already found that there are distortions in potential distribution due to the presence of an US probe.31

Mass Transfer Measurement in a Laboratory Scale System

Since the effect of material transport within a narrow gap using US was not known, the starting point for our analysis was to examine if an experimental system, which could accommodate closely placed anode, cathode, reference electrodes and US horn could be designed. Figure 2 shows a laboratory scale system used by our group, where two electrodes were placed in close proximity within a cylindrical reservoir. The distance between the two electrodes could be controlled via a screw system, and the system was calibrated so that we could adjust the gap reasonably accurately. The US probe was placed above it to focus the US agitation directly within the gap. The US system (SONICS Vibra-Cell VC505 Processor) with a titanium alloy tip was operated at a fixed frequency of 20 kHz, and the power was varied between 9-29 W/cm2 (25-75 W L−1).

The detail for the placement of the reference is shown in Fig. 3. A reference probe could not be placed within the inter-electrode gap, because this could cause a disturbance in the electric field between

the two electrodes. Therefore, a reference probe was placed 5 mm above and to the side of the gap. The design of the electrochemical cell allowed one to assess the effect of two different parameters: (1) the inter-electrode gap which defined the constrained space, and (2) probe-to-electrode distance which controlled the power delivered into that space. The placement of the reference above the plane of the anode and cathode, as well as the insertion of the US tip (or horn), which can serve as a third electrode, is a departure from a standard three-electrode set-up used for limiting current measurement.

The methodology in the limiting current technique employs the collection of current vs. potential data. When an electrochemical reaction is kinetically controlled, the current density increases with applied potential. As mass transfer limitations are encountered, the current density remains nearly constant with increasing potential, and is called the limiting current plateau. The mass transfer boundary layer, δ, is related to the plateau current, called the limiting current, by the following equation (1)

Here, iL is the value of the limiting current, n is the number of electrons transferred, F is Faraday constant, D is the diffusion coefficient, and Cb is the bulk concentration of reacting species in solution.

Figure 4 shows the limiting current data obtained for a 0.1 M CuSO4/0.1 M H2SO4 electrolyte using this apparatus. The conditions for electrode gap, horn-to-electrode distance, dp, and measurement conditions are provided in the caption. The oscillations in current are due to cavitation activity near the electrode surface. As the horn was brought closer to the inter-electrode gap, the current potential data show distortions, some of which show up as apparent hydrogen evolution commencing at a low overpotential. This distortion is caused by a third metallic, grounded electrode (horn) placed within the electrochemical cell.32 However, limiting current plateaux were still identifiable, and they were used to determine the mass transfer boundary layer.

The limiting current data were used to develop mass transfer correlations within the constrained volume. Sherwood-SchmidtReynolds number correlations for different electrode gaps and hornto-gap distances are listed below:32,33

In these equations Sh, Re and Sc correspond to Sherwood, Schmidt, and Reynolds numbers respectively, and de and L are the equivalent diameter and length, respectively. Equations 2a and 2b correspond to electrode gaps of 10 mm and 1.5 mm, respectively. These correlations show that for a wider gap, developing turbulence controls mass transfer. For the narrower gap, one obtains a fully turbulent condition, presumably due to eddies generated within the gap.

Mass Transfer Measurement in a Large Scale 18 Litre Tank System

Measurement of limiting current within an industrial scale tank system is more complicated. There are two major issues— tank systems have lower power, and the power is very evenly distributed.34 In addition, much of the earlier work has focused on high power to influence reaction chemistry, and studies related to microfabrication have shown that lower power may be more useful for electrodeposition.23,24

Figure 5 shows the design for the electrodes with a narrow gap within a tank system. The electrodes are placed at the center of the tank, and connectors to the electrodes as well as the inter-electrode gap are maintained via the design of an appropriate holder which is described in detail elsewhere.33,35 The gap between the electrodes was set at 1.5 mm, achieved by placement of spacers in the corners and one in the center of the plate. The tank was 18 L, and the electrode size was 74 mm × 105 mm (A7 size), much larger than the lab scale system (which was of 10 mm diameter). The tank operated at 30 kHz and limiting current experiments were performed at 30, 40 and 60 WL−1

Figure 5 also shows the detail of anode and cathode used in these experiments. The cathode was a Perspex plate with a copper contact at the back. Two square slots 10 mm × 10 mm, near the center and edge, were made where copper inserts were placed, depending on the position where the limiting current had to be measured. The anode was an A7 size copper plate, the same size as the Perspex plate. Limiting currents were measured via galvanostatic means. Although limiting currents would normally be measured potentiostatically, when such large electrodes are used, there can be significant potential distribution, which makes data difficult to interpret. Therefore,

measuring an average current and cell potential to locate a plateaux current provides a practical method to determine limiting current in a tank-type reactor.

The limiting currents at locations (A) and (B) were determined to be similar; at location A, δ was found to vary between 15 μm and 19 μm, and it was 17 μm at location B, indicating that the variation in mass transfer at the edges and center are not significant. The Sherwood-Schmidt-Reynolds number for this system was found to be:35

These analyses show that while US tanks are capable of significantly increasing agitation within the narrow gap between electrodes of A7 size, the effect of US streaming is less pronounced. This tank system was used to carry out electrodeposition of copper structures at the micron scale, which required photolithographed substrates. It was found that powers higher than 10 WL−1 caused de-adhesion of the photomasks from substrates.23,35 It was found that low powers were favourable for microfabrication due to increased longevity of masks. Therefore, increasing mass transfer is not the sole criterion for optimisation of microfabrication systems.

Imaging

While mass transfer correlations are useful chemical engineering tools for design, a closer inspection of mechanistic processes during US application is also necessary. Imaging techniques have previously been used to visualise cavitation and the phenomenon of micro-jetting using special photography.36 The experiments managed to capture the precise moment of a cavitation bubble collapse and the formation of a micro-jet. There is also work using fluorescence microscopy to detect microbubbles which have propagated from an ultrasound probe,37 studying the effect of collapsing bubbles on the surface of a cell.

Although it is crucial to quantify cavitation activity as a function of the process parameters, there are a limited amount of studies. In some very interesting work, the laser phase-Doppler technique was used to study bubble velocity, size distributions, and volumetric flow of ultrasonic cavitation bubbles propagating from a 20 kHz ultrasound probe38 in a 1.7 L tank and a free-flowing geometry. The experiments demonstrated that the jet from the probe had similar hydrodynamic properties to turbulent circular jet flows. The work also showed that ultrasound power increases bubble velocity quasi-linearly, and changes bubble diameter which was dependent on distances from the probe tip.

The authors considered the feasibility of using optical techniques to visually capture the movement of cavitation bubbles within a narrow gap of <1 mm. An imaging technique was deemed feasible for a thin gap since light could be transmitted through the electrolyte in the gap, and be interpreted from transmitted images. Therefore a glass cell was constructed with borosilicate windows positioned (almost exactly) parallel to each other with a gap of <1 mm. A 20 kHz ultrasound probe was used as the ultrasonic source, and was placed 3 cm above the gap. The glass cell was filled with 500 ml of electrolyte, and the probe tip was dipped into the solution to generate US agitation. Although the full details of the imaging experiment are beyond the scope of this paper, other additional components required were a light source, a diffuser, slit, iris, two achromatic lenses, two mirrors, a razor blade, and a Nikon D50100 camera.

Both Schlieren and Shadow Graph imaging were tested with the assistance of Patrick Bunton (visiting professor from Vanderbilt University), of which Shadow Graph appeared to provide reasonable images. One frame from the videos during the first few seconds of applying ultrasound at 23 W L−1 is shown in Fig. 6. Although the camera used in this experiment operated at only 25 frames per second, the tracks of the streaming bubbles are discernible, shown by the dark vertical lines indicated by the arrows. It is known that ultrasonic cavitation effects can be captured using a synchronized high-speed stroboscopic Schlieren imaging technique,39 using a

The limiting current was measured at location (A) and (B), i.e., at the center and edge of the plate to detect differences in agitation. (Adapted from Ref. 23 and 33.) (continued on next page)

cavitational trigger, such as sono-luminesence and cavitation noise. If a similar technique were used, it is likely that bubble movement within narrow gaps could be observed.

Outlook

Overall, the work shows how US can enhance agitation greatly, especially in constricted spaces. Our work discussed the need of deeper understanding of mass transfer due to US agitation within constricted spaces. The logical development of electrochemical apparatus and adaptation of experimental techniques to quantify mass transfer and develop correlations from these measurements and the challenges faced during the measurements have been outlined. Going further, the use of imaging techniques, which can help in visualisation of cavitation bubbles and elucidate agitation mechanisms, have been discussed.

In Situ Ultrasonic Dispersion in Multiphase Electrolysis Systems

Water is generally regarded as the most ideal solvent for many types of organic electrosyntheses because of good conductivity and polarity, stabilizing effects on radical intermediates, and straightforward product isolation by extraction or filtration.1 However, a large number of organic materials cannot be efficiently electrolyzed in aqueous solutions due to their low aqueous solubility. Hence, in most cases, the electrolysis of water-insoluble materials has been carried out in organic polar solvents. However, the electrolysis in organic solvents is practically disadvantageous based on aspects such as conductivity, operational costs, and safety. Therefore, the extension of the range of systems undergoing an electrochemical synthesis in water is of considerable interest and systems employing surfactant-stabilized emulsions and suspensions have been investigated.2 The presence of surfactants or “carrier molecules” may cause other problems such as difficulty post-synthesis in separation of products from the reaction mixtures and additional production of wastes. Hence, it is desirable to conduct emulsion or suspension electrosynthetic processes in the absence of surfactants or stabilizers in order to fulfill the potential of electrosynthesis as a green methodology. Ultrasonic dispersion in situ during electrolysis can be employed to create conditions (see sidebar) of enhanced multiphase reactivity and enhanced mass transport towards the electrode.

Electrochemical Reaction of Water-Insoluble Organic Droplets in Aqueous Electrolytes Using Acoustic Emulsification

It is well known that ultrasound allows multi-phase systems (liquid/liquid, liquid/solid, or liquid/gas) to be efficiently homogenized (given the right choice of frequency, power, and conditions). For example, ultrasonication provides stable emulsions without stabilizing agents simply by mechanical dispersion forces, which arise at the liquid/liquid phase boundaries.3 This has been termed as “acoustic emulsification.”4 Furthermore, it is also known that emulsions prepared by acoustic emulsification have the characteristic of giving narrow droplet size distributions in the submicrometer range.5 Hence, electrochemical systems can be designed for these droplets to be electrolyzed smoothly at electrodes in the presence of power ultrasound. Practically, electrochemical cells can be immersed into ultrasonic bath systems, or sonic horn probes can be immersed directly into the electrochemical systems (with precautions to avoid shunt currents). Figure 1 shows a typical reactor system with a horn emitter pointing at the working electrode surface. The distance between horn and electrode as well as the power of sound emission affect the diffusion layer at the electrode (as well as causing emulsification).

In situ emulsification of an oil phase into the aqueous electrolyte induces practically useful reaction rates even without any added emulsifying reagents. Compton and coworkers reported that apparent diffusion rates of water-insoluble molecules (diethylmaleate, diethylfumarate, and diethylacetylene dicarboxylate) in emulsion systems under ultrasonication (voltammetrically estimated transport rates) were large enough to perform preparative electrolyses.6 Also, Kolbe electrolyses at both platinum and at boron-doped diamond working electrodes were reported.7 The highly water insoluble C10,

Effects of Power Ultrasound During Electrolysis

• vigorous agitation or macro-streaming due to sound induced convection

• micro-streaming at the electrode surface creating high shear forces, cleaning, or even cavitation and erosion

• fast mass transport as expressed by a Nernst diffusion layer thickness down to 1 μm

• turbulent conditions with impacts of microdroplets and particles

• heating of the solution due to energy dissipation (this effect can be used to calibrate the energy flow from sound emitter to electrolysis cell)

• some chemical reactions (radical formation) due to cavitational processes can occur but usually at a rate much lower than that of the electrolytic process

C12, and C22 alkane products (3) as well as some ester products (4) were ultrasonically dispersed and removed from the electrode surface (Fig. 2).

Atobe et al. reported that electrochemical oxidation of waterinsoluble amines (noctylamine and ndecylamine) was accomplished in aqueous electrolytes using acoustic emulsification and gave much higher current efficiencies compared to those obtained under conditions of mechanical stirring (see Table I).8 In addition, they also

proposed that the smooth electrochemical reaction in the emulsions prepared by ultrasonication took place via direct electron transfer between the electrode and the water-insoluble organic droplets (see Table I).

A novel electrolytic system for anodic substitution reactions using acoustic emulsification was developed by Atobe and coworkers.9 This system involves the generation of a carbocation by anodic oxidation of substrate, and then its reaction with nucleophile droplet formed by ultrasonication (Fig. 3). In this system, even if the oxidation potential of nucleophile is lower than that of substrate, the substrate was predominantly oxidized to give the corresponding cation intermediate because the nucleophile phase which was insoluble in an electrolytic medium was electro-inactive. In addition, the overoxidation of the desired products was considerably suppressed by the extraction of products from electrolyte solution into the nucleophile phase. As a result, anodic substitution reaction of several carbamates with allyltrimethylsilane was carried out to provide the corresponding products in good to moderate yields (see Table II).

A related area of application of ultrasound in multi-phase electrosynthesis is in the formation of polymer films.10 Dualfrequency methods were developed to achieve the synthesis of very densely packed polymer colloidal films.11

Ultrasonic Dispersion in Electrosynthetic Processes at Suspended Particle-Electrodes and Slurry-Electrodes

Suspended particle-electrodes or slurry-electrodes can be used to achieve a high space time-yield since these can play a role as an electron transfer mediator and possess a large surface. Therefore, an application of suspended particle-electrodes to electrosynthetic processes has been studied by many researchers.12-15 However, the particle-electrode is usually aggregated during electrolysis in the absence of stabilizer and the total surface area of the electrode is reduced. To overcome this problem, ultrasonic dispersion is very useful for suppression of agglomeration of particle-electrode. Atobe et al. examined ultrasonic effect on the electroreduction of acrylonitrile at suspended lead particle-electrode (see Fig. 4).16 The product selectivity for adiponitrile 1, which was formed as the corresponding hydrodimeric product along with propionitrile 2 as the hydromonomeric one in the cathodic reduction of acrylonitrile, was increased by addition of lead particles as a particle-electrode, and moreover the selectivity was further increased under ultrasonication. It was concluded that ultrasonic effects were observed not only for the mass transport of lead particles to the feeder cathode but also as

an increase in the effective surface area of the particle-electrode by ultrasonic dispersion.

Direct interaction or “impact” of microparticles17 and nanoparticles18 can be enhanced and studied in the presence of ultrasound. Sono-electrolytic solid state reactions have been reported for example for Fe2O319 and for graphite powders with and without chemical surface modification (see Fig. 5).20 The characteristic “spike” signal recorded for impacts can be related to the point of zero charge (PZC), the capacitance, and the radius of particles. The impact frequency was found to be related to the dispersed mass of carbon particles.

For these solid particles collision rates with the electrode and transport rates are enhanced. Time-resolved information about the individual particles is obtained. However, in future also quantitative conversion may be feasible with sono-electrosynthesis providing a new way for clean solid-solid or electro-catalytic transformations.

Conclusions and Outlook

Given the fact that power ultrasound substantially increases mass transport, it is now possible to electrolyse faster even for slowly diffusing droplets, clusters, or particles.21 Therefore processes with “slow diffusers” such as colloids or nanoparticles are most affected by the application of ultrasound due to overwhelming mass transport effects. A new development is the application of “impact processes” where interaction with solid particles are ultrasonically enhanced

or particles are accelerated onto the electrode surface to undergo electrolysis. This could lead to entirely new types of electrode reactions based on nanoparticles and nanomaterials as long as the underlying principles of ultrasound – multi-phase interactions are better understood. Particle impacts have been shown to be sometimes very energetic—even leading to partial melting of metal particles.22 We believe that, although electrosynthesis needs to be performed with simple tools and practical inexpensive reactor systems, there is still a need to enhance reactions and to trigger unusual surface conditions and processes by power ultrasound. In future ultrasound-enhanced multi-phase electrosynthesis with slow diffusers, microdroplets, or particles will be developed further and could be applied to electrosynthetic reactions that are useful for organic syntheses. © The Electrochemical Society.

Luminescence and Display Materials Division Centennial Outstanding Achievement Award

Pieter Dorenbos received his physics education and did his PhD research at the University of Groningen, where he was appointed in July 1988 as assistant professor at the Technical University of Delft, The Netherlands.

He remained employed at TUD, where he is now heading, as full professor, the section Luminescence Materials in the Faculty of Applied Sciences. He started with projects on the development of new lanthanide activated scintillation crystals for detection of ionizing radiation. This ongoing research has resulted in various new patented scintillators that led to successful commercial products. Notably, LaBr3:Ce3+;Sr2+ is the best scintillator available to detect the energy of gamma photons.

Dorenbos’ interest broadened to all types of lanthanide activated luminescence inorganic compounds, and he became particularly interested in where lanthanide energy levels are located within the bandgap, and how that affects luminescence properties. This work resulted in various empirical models to construct diagrams showing all lanthanide levels within the band gap.

In 2012, he presented the chemical shift model that enables to relate energy levels of host bands and lanthanide impurity states in different compounds to a common energy reference, i.e., the vacuum level. It is a unique approach that is being adopted in the field.

He is currently interested in the energy level locations of transition metal elements and 6s2-elements like Bi3+. His mission is to develop new luminescence materials by rational design instead of serendipity.

Calgary Student Chapter

A new executive committee for the ECS Calgary Student Chapter was officially announced for 2018, involving Behzad Fuladpanjeh Hojaghan (president), Annie Hoang (vice president), Yalda Zamani Keteklahijani (secretary), and Katelynn Daly (treasurer), as well as members-at-large Marwa Atwa, Tianpei Shu, Hamideh Eskandari, and Umer Farooq. Atwa will also serve as the membership coordinator for the chapter. In addition, the chapter launched a new profile on Twitter (@ecs_calgary) to announce upcoming events and reach out to the Calgary community through social media.

The first event of 2018 involved the chapter’s participation in the Graduate Students’ Association’s Reverse Science Fair on the afternoon of March 3 at the University of Calgary. Traditional science fairs allow young students to present a project or experiment to a panel of judges, whereas a reverse science fair involves scientists and engineers presenting a demonstration to young students. The purpose of the event was to promote interest in science and engineering among young children. The chapter decided to set up an electrochemistry booth to demonstrate fruit and vegetable operated batteries using lemons, limes, apples, bananas, and potatoes as the electrolyte. Nearly 100 participants attended the event, including grade school children and their parents. Attendees were initially asked to guess at which fruit/vegetable battery they believed would work, and then completed the circuit to light up an LED bulb. For each option, the children also measured the cell potential with a voltmeter to determine which fruit/ vegetable was the best battery. The chapter plans to organize more science outreach events during the year to increase interest in science and promote electrochemistry and its many practical applications.

Two chapter members, Atwa and Hoang, traveled to the University of Alberta in Edmonton for the ECS Canada Section’s spring meeting on May 26, where they presented their work on the corrosion resistance of carbon supports in PEM fuel cells, and core@shell nanoparticles as catalysts for direct alcohol fuel cells, respectively. The chapter’s faculty advisor (Dr. Viola Birss) was an invited speaker

at the meeting, where she presented her research group’s work on nanoscale templates and scaffolds for electrochemical applications. This meeting occurred one day before the 101st Canadian Chemistry Conference and Exhibition, also held in Edmonton, where Hoang, Daly, and Atwa gave oral presentations in the Materials for Renewable Energy Technologies symposium while gaining valuable knowledge about advances in electrochemistry and materials science research.

Norwegian University of Science and Technology Student Chapter

On a beautiful day in May 2018, the ECS Norwegian University of Science and Technology Student Chapter hosted its annual group seminar at Lian Restaurant in the leafy suburbs of Trondheim. Around 40 students, professors, and chapter members attended to hear about the research being done in the group.

After an introduction from the chapter’s president, Kristian Thorbjørnsen, a number of master’s students, PhDs, and postdocs presented their work. The talks were on topics including reverse

electrodialysis, aluminium production, and catalysts for water electrolysis. The chapter also got an in-depth introduction to a newly purchased Raman spectrometer from Professor Andreas Erbe, selfconfessed Raman enthusiast.

Afterwards, the chapter headed down to the beautiful Lianvatnet Lake, where the lively discussion continued over a few rounds of volleyball and a dip or two in the lake, with more events for the group planned for the future.

University of Washington Student Chapter

The ECS University of Washington Student Chapter continued its dedication to two core missions: aiding members in their career development and positively affecting its community through outreach. Achieving these goals required ECS@UW to organize activities that prepared its members for conferences, provided opportunities for professional networking, taught elementary school students about electrochemistry, and offered educational seminars for its members.

The chapter proudly reports that 22 of its members participated in the 233rd ECS Meeting held this May in Seattle, WA. Prior to the conference, ECS@UW organized several events to position its members for success. Specifically, ECS@UW arranged multiple sessions for members to practice oral presentations and receive feedback from their peers prior to the conference. Moreover, Matthew Murbach, an ECS@UW member, planned eight Python tutorials held on a weekly basis leading up to the conference. These tutorials served to prepare students with minimal prior data science experience to fully participate in ECS Data Sciences Hack Week at the meeting.

On May 24, ECS@UW hosted its second annual industry panel. This year’s panel was selected according to the themes of clean energy and data science, thus embracing the recent boom in electrochemical publications at this intersection. Accordingly, ECS@UW partnered with the local student-led organization Diversity in Clean Energy to

invite six panelists from organizations ranging from local start-ups to international corporations. Represented companies included Hive Battery, E8, Distributed Energy Management, DVN-GL, KPMG, and Doosan GridTech. Representatives were separated into two panels, the first fielding questions regarding start-ups, and the second fielding questions on the transition from academia to industry. These panels were complemented by a networking session enabling students to interact with the local professionals. In total, the event spanned four hours. ECS@UW gratefully acknowledges sponsorship of this event by the Clean Energy Institute and eScience Institute.

On April 19 and 20, ECS@UW participated in the University of Washington’s Engineering Discovery Days. At this event, UW students and faculty facilitated numerous hands-on experiments oriented toward fourth to eighth grade students. This afforded elementary school students a fun environment for learning and the opportunity to witness the exciting nature of STEM research. Here, ECS@UW featured its popular electrodeposition experiment, Enginearrings, which involved the anodization of titanium wires to produce colorful patterns. These wires were then bent into earrings and distributed as keepsakes to attendees. In total, Engineering Discovery Days reached over 10,000 attendees and benefited from the civic involvement of over 1,200 UW students.

Finally, ECS@UW continued its theme of educational seminars. This included a series of student-led, biweekly presentations on characterization techniques that concluded with presentations by Elena Pandres and Evan Jahrman on electron microscopies and X-ray

absorption spectroscopies, respectively. This summer, ECS@UW will continue its Coffee & Electrochemistry book series with weekly discussions focused on the chapters of Electrochemical Methods by Bard and Faulkner.

Improving its community and aiding the career development of its members remain the central foci of ECS@UW.

Drexel University Student Chapter

On May 3, 2018, electrochemistry-focused students and professors at Drexel University got together to participate in the annual gathering of the ECS Drexel University Student Chapter. The event was organized by the Drexel University Student Chapter’s board, led by Mallory Clites, chapter president, and Ekaterina Pomerantseva, chapter faculty advisor.

This year, for the first time, the chapter hosted a Family Feudstyle game, called Electrochemistry Feud, in which students from the Chemical & Biological Engineering and Materials Science & Engineering Departments at Drexel competed on opposite teams to answer opinion-based questions that electrochemists across the

country had taken a survey on. The surveys themselves had been electronically distributed to university professors, postdocs, graduate students, national laboratory scientists, and industry professionals working in the field of electrochemistry. A total of 57 responses had been collected and analyzed to determine the top six answers to each of the 10 survey questions. The survey questions focused on electrochemical energy storage and general electrochemical research. The surveys included such questions as “Who do you believe to be the most influential electrochemist of all time?” to which the most common answers were Michael Faraday and John Goodenough. Another question asked, “What material do you believe

can revolutionize the field of energy storage?” and the common answers were MXenes, a versatile family of transition metal carbides and nitrides that offer capacitive energy storage and high electron conductivity (discovered at Drexel in 2011 by students working under Dr. Yury Gogotsi and Dr. Michel Barsoum) and metal organic frameworks, stable structures that possess a great degree of open space where significant amounts of large beyond Li-ion charge carriers can insert with minimal strain. For the question “What is your favorite electrochemistry-related journal?” the most common answer was the Journal of The Electrochemical Society

Team MSE was composed of five PhD and MS students, Varun Natu, Asya Sarychevaa, Samantha Buczek, Yongwei Li, and Patrick West, while Team CBE included students Sophia Lee, Luis Rebollar, Yawei Li, Swarnendu Chatterjee, and Rahul Pai. Dr. Katie Van Aken, a postdoctoral researcher at Drexel University, acted as the game show host.

The teams battled it out over the course of the 10 survey questions. Team MSE led for the first seven rounds, correctly guessing the most common answers to questions such as “What is the most important battery ever discovered?” and “What application do supercapacitors have the capability to outperform batteries in?” However, Team CBE managed to pull ahead in the eighth round, correctly guessing the top four most popular electrochemistry-related journal responses, and ultimately was crowned the winner. More than 40 students and professors from Drexel University, as well as guest visitors from the

University of Pennsylvania, attended the event. The Electrochemistry Feud game was followed with lunch and a poster session in which the students were able to discuss their ongoing research. The chapter would like to thank everyone who took the time to fill out the survey that made its event a success. The chapter is also very grateful to The Electrochemical Society for sponsoring its event.

BECAUSE LINEARITY MATTERS

Bio-Logic introduces EIS quality indicators*

Detect non-linearity : Total Harmonic Distortion - THD

Detect non-stationarity : Non-Stationary Distortion - NSD

Detect noisy response : Noise to Signal Ratio - NSR

Electrochemical impedance spectroscopy (EIS) measurements at two different AC amplitudes (50 mA & 400 mA) are performed on the same Li-ion battery cell.

The non-linearity of the cell at low frequency is evident in the Nyquist plot to the right.

After an equivalent circuit fit analysis, the charge transfer resistance is over-estimated by 8% with the 400 mA AC amplitude measurement.

The THD indicator can be used to detect this non-linearity and help optimize the stimulation amplitude.
