2015-2016 Annual Report Singh Center for Nanotechnology

A Message From the Director We are proud to present the 2015-16 Annual Report of the Singh Center for Nanotechnology at the University of Pennsylvania. The leadership and staff of the Singh Center endeavor to foster nanotechnology-enabled innovation, scientific discovery, and intellectual collaboration, assisting internal and external users in addressing their nanoscience and application needs by: • providing a forum for intellectual exchange between academic (both Penn and external) and industry users — in the past year, the Center has served more than 400 researchers, resulting in over 250 publications and conference talks, and multiple patent applications. Papers were published in fields ranging from nano-biogenomics to nanophotonics to microelectromechanical systems to nanomaterials to nanoelectronics, in prestigious journals and conferences that include Nature, multiple IEEE Transactions, Physical Review, and Science; • considering user needs as a basis for new equipment acquisition and invention — over 19 new nanofabrication and analysis tools have been purchased to meet these needs; •

developing new fabrication processes that not only contribute to the users’ end application but also further the fields of nanofabrication and nanomanufacturing; Singh Center staff have presented results at the NNT and EIPBN conferences and published results in important journals such as the Journal of Vacuum Science and Technology; and

• Hosting a Nano User Day exhibition, in which nearly 200 researchers and industry representatives had an opportunity to exchange ideas, showcase their latest results, and hear speakers from academia, industry and government on important new topics in nanotechnology. New advances in nanofabrication are disseminated not only in peer-reviewed journals, but also through a process wiki. This dissemination promotes the emergence of new ideas and innovations, and enables widespread process adoption across not only the Singh user base, but also around the world. Over sixty process recipes developed by the Singh Center staff and users have been published to Scholarly Commons, an open website, and others have downloaded these reports 5,800 times worldwide, including researchers from Europe, South America, Australia, and Asia.

In the Fall of 2015, the Singh Center was chosen to become the Mid-Atlantic Nanotechnology Hub (MANTH), one of sixteen nodes of the National Science Foundation’s (NSF) new National Nanotechnology Coordinated Infrastructure (NNCI) program. This selection of the Singh Center resulted from a competition among most of the leading nanotechnology-oriented universities in the country. The NNCI program is designed to facilitate access to the Singh Center’s nanotechnology infrastructure for academic, industry, and government researchers across the region and nationwide, with the goal of substantially increasing the accessibility of the community to nanotechnology infrastructure, thereby promoting regional and national nanotechnology-enabled innovation and scientific discovery. In addition to research, the Singh Center engages new users (and potential future nanotechnologists) through on-site research reviews, K-12 outreach for local Philadelphia schools, participation in Philadelphia Science Festival, and on-site summer research experiences for undergraduates. Last year, the Singh Center collaboratively hosted the NanoDay@Penn event in which 165 high school students participated from 8 schools in Philadelphia and the surrounding area. This highly rated program introduced students to aspects of nanoscience and nanotechnology through tours and demonstrations. More than 150 postdocs, staff, and especially Penn School of Engineering students who gained valuable experience teaching others, ran these activities. Along with direct educational outreach, the Singh Center has made significant strides to integrate itself into Philadelphia and the surrounding area’s technology development community by participating in events such as: the Delaware Valley Manufacturing Summit, Philadelphia Tech Week, the Rain Conference, and hosting our own Entrepreneurial Open House (with accompanying Seed Grant Competition). The Singh Center is also working hand in hand with organizations such as the Greater Philadelphia Chamber of Commerce and Philadelphia Start-up Leaders to foster growth in nanotechnology research and innovation throughout the Mid-Atlantic region. We are very proud of what the Singh Center has accomplished over the last year, and are looking forward to continued contributions to the region’s and nation’s growth and impact in nanotechnology research, development, and implementation. Sincerely,

Mark G. Allen Director, Singh Center for Nanotechnology University of Pennsylvania

Engaging Medicine – A Radiology Example School of Medicine

Etching Conformal Imprint Structures

Among the researchers to whom we have taught basic microfluidics, a handful have required more sophisticated fabrication techniques. One such example is Dr. Steven Kadlicek from the Department of Radiology at Penn. Professor Kadlicek’s group is focused on experimental studies of altered metabolism in heart, liver and brain, and of the greatly accelerated metabolic processes in cancer. His team was unable to use soft lithography techniques (PDMS-based) since their HPLC devices were inherently high pressure and had the requirement of being hermetically sealed. Singh staff members partnered with his group to employ laser micromachining of silicon for channel formation and then encapsulated the structure with anodically bonded glass. In order to make fluidic connections, we employed laser micromachining (drilling) again to make multiple ports on the structure.

In collaboration with AMO GmbH, etch processes were developed to demonstrate a SCIL (surface conformal imprint lithography) process for grating waveguide structures in tantalum oxide. This work was presented as a poster at the 14th International Conference on Nanoimprint and Nanoprint Technology in October 2015.

Electron Beam Lithography Enhancements Two process developments were presented at the EIPBN Meeting in May 2016: “Shape Positional Accuracy Optimization via Writing Order” and “Metal Free Adhesion of Au onto Si Native Oxide”. The conference proceedings will be published in the Journal of Vacuum Science and Technology Part B. The goal of this work was to develop and share practical, robust, reproducible processes for the diverse nanofabrication lithography community. Hence, we chose a topic such as adhering gold directly to Si without a Cr adhesion layer (important for the plasmonics community).

Polar Insulators and Tunable Dielectrics – Drexel University The Spanier group at Drexel University has been using the Singh Center to carry out photo- and electron-beam lithography, RF sputtering and electron beam evaporation of metal, transparent conducting, and dielectric films to produce electrodes onto insulating oxide film and bulk materials. Students and postdocs in the group and the group’s research have benefitted from expert training, and guidance with and collaboration in process design and development provided by the Center’s staff. The devices and test structures fabricated are enabling the Spanier group to investigate fundamental nature of light-matter interactions in polar insulators, and the properties of tunable dielectrics, with applications in photovoltaic solar energy conversion and frequency-agile filters and antennas.

Soft Lithography Resist Adhesion Testing Strong adhesion of SU8 resist to the substrate is critical in soft lithography. However, proper substrate preparation protocols lack specifics in published procedures. As a result, researchers find themselves wasting hours of lab time attempting to work out their own protocols. We tested multiple surface preparation protocols for silicon substrates that are commonly used. This article has been published in Scholarly Commons and downloaded over 140 times.

Nanophotonics – Tornado Spectral Systems

The search for an interfacing device that stimulates and senses neural signals in the brain is an important and active area of research due to ever increasing needs for understanding the brain. Development of an implantable neural prosthetic device (NPD) is crucial for a fundamental understanding of brain function at a specific site. We will employ a Si carrier layer for insertion with the size of 10 - 20Îźm. While the compliance will be controlled geometrically by making multiple holes in the electrode, the thick solid Si remains to provide enough mass for insertion. The metal electrode will be deposited on Parylene and encapsulated with bio-compatible materials such as collagen and Matrigel.

Tornado Spectral Systems is an early stage Ithaca, NY based company that utilizes nanophotonic structures as visible light dispersive spectrometers. At the Singh Center, we have developed silicon-oxynitride films with a repeatable, tightly controlled refractive index that clads their waveguide structures. In fact, we can control refractive index to the 3rd decimal place, which is a rather difficult specification to achieve. Tornado Spectral Systems touts the use of dispersive nanophotonic devices since, in the absence of moving parts, they have inherent speed and sensitivity when compared to standard interferometric and scanning spectrometers.

Directed Self Assembly of Block Copolymers Directed self-assembly of block copolymers (BCPs) is considered as one of the most promising advanced lithography approaches for applications not requiring precise registration. This lithographic approach can make sub-20 nm patterns on a 6-inch diameter substrate in parallel and at low cost, using the selfassembly of BCP and guide patterns created by e-beam or EUV lithography. The goal of this project, as an internal initiative by the Quattrone Nanofabrication staff, is to make this technique available at the Singh Center and the Mid-Atlantic community. The guide patterns for lines (chemo- and grapho-epitaxy) and holes (contact shrink hole) will be developed as next steps.

Flexible Nanoparticle Electronic Systems

Nanochannel Assembly and Packaging – Bio Nanogenomics

Recent work by Dr. Cherie Kagan and Dr. Christopher Murray opens the door for electrical components to be built into flexible or wearable applications, as the lower-temperature process is compatible with a wide array of materials and can be applied to larger areas. Nanocrystal-based field effect transistors were patterned onto flexible plastic backings using spin coating but could eventually be constructed by additive manufacturing systems, like 3-D printers. The researchers began by taking nanocrystals, or roughly spherical nanoscale particles, with the electrical qualities necessary for a transistor and dispersing these particles in a liquid, making nanocrystal inks. Kagan’s group developed a library of four of these inks: a conductor (silver), an insulator (aluminum oxide), a semiconductor (cadmium selenide) and a conductor combined with a dopant (a mixture of silver and indium). Primarily, the National Science Foundation through its Materials Research Science and Engineering Centers Award DMR-1120901 supported the research.

Bio NanoGenomics, Inc., from San Diego, CA has been working at the Singh Center for more than a year, primarily in final assembly of devices. After their nano channel chips have completed fabrication at a wafer foundry, the company requires wafer bonding services. Their chips are designed to unravel, sort, and confine long DNA fragments in a linearized conformation. The nanoscale channels on their chips were designed to allow only a single long-strand DNA molecule to travel through while preventing the molecule from tangling or folding back on itself. The Singh Center was able to customize a wafer bonding chuck and alignment system for their chips, enabling full anodic bonding and high-pressure operation of the device for electrophoretic transport.

Bulk Acoustic Wave Devices – Akoustis Technologies Akoustis Technologies, Inc., is an early stage company from Huntersville, NC that designs and fabricates Bulk Acoustic Wave (BAW) devices through the use of single crystal piezoelectric materials (AlGaN). These devices exhibit 30% improvement in acoustic performance when compared to incumbent thin film technology (e.g., in cell phones). Their BAW filters target the mobile wireless market for enhancement in bandwidth, insertion loss and steep side-wide rejection. Akoustis performed the backside lithography and silicon etching, as well as backside lithography and electrode deposition, at the Singh Center.

Cell Elasticity With Altered Cytoskeletal Architectures Across Multiple Cell Types Mechanotransduction describes the mechanism by which cells respond to their physical environment by translating mechanical stimuli into biochemical signals. The reverse also occurs; biochemical signals cause a cascade of reactions that alter the way the cell behaves and deforms mechanically. For example, changes in cell elasticity have been implicated in the pathogenesis of many progressive diseases including vascular diseases, kidney disease, malaria, and cancer. Our research lab is interested in evaluating the connection between elasticity and cell health. We demonstrated the structural importance of an intact actin cytoskeleton in the elasticity of five cell lines. We also showed that destabilizing microtubule dynamics resulted in increased cell stiffness for two cancer cell lines. Cell elasticity is a critical component in cancer cell metastasis as the cell must be able to deform significantly to squeeze through endothelial layers to enter the blood stream. We anticipate these findings to contribute to the understanding of the role of elasticity in cancer cell metastasis.

SCN AR 2015-16Pass 2.indd 22

This complex interplay between biochemistry and mechanics is further influenced by the fact that the cell interior is a very crowded chemical space in which the volume fraction of proteins can reach up to 40%. This large volume fraction limits diffusion of molecules and organelles within the cytoplasm and therefore affects the rates of chemical reactions in the cell. Our team has developed a protocol for injecting quantum dot structures within living cells and tracking their movements. From this information, we can extract diffusion parameters. Together with our elasticity findings, we can explore the interplay between cell mechanics and intracellular diffusion, which will add new insight to the burgeoning field of nanobiomedicine, nanotoxicology, and drug delivery and transport.

Singh Center for Nanotechnology

Nanopore Research for DNA Detection and Sequencing The Drndić lab at Penn researches nanopores for the application of DNA detection and sequencing. Nanopores are nanometer-sized holes in thin, insulating membranes. These thin membranes (e.g. 10 nm-thick silicon nitride) are used to separate two chambers of salt solution with DNA molecules floating on one side. When a bias is applied across the membrane, the only path for ionic current to flow is through a single nanopore in the membrane. As negatively-charged DNA molecules translocate through the nanopore, the DNA molecule blocks a portion of the ionic current and is easily detected as spikes in the resistance of the nanopore. A main objective of the research in the Drndić lab is to push this technique down to single-base resolution, so that the sequence of a DNA molecule can simply be read as it translocates through a nanopore. The Drndić lab uses the transmission-electron microscopes (TEMs) in the NCF to drill nanopores for DNA detection experiments. In the JEOL 2010F microscope, the high-energy electron beam (200 keV) can both knock out atoms from a material as well as be focused to a probe size less than one nanometer in diameter. This combination allows a user to sculpt and modify a material on the nanometer scale as well as drill nanopores that are comparable in diameter to DNA molecules (1.3 nm for single-stranded DNA). The Drndić lab has used the TEMs in the NCF to sculpt nanopores in graphene, silicon nitride, amorphous silicon and black phosphorus.

SCN AR 2015-16Pass 2.indd 23

Nanopore devices fabricated in the NCF have been able to differentiate between short (30 base pair) ssDNA homopolymers of polyA, polyC, and polyT. A focused TEM electron beam was used to thin down a silicon nitride membrane in order to create nanopores 1 nm in length and 1.3 nm in diameter. Nanopores can be tuned to any size, and were also used to investigate microRNAs, RNA/Antibiotic complexes, gold nanorods, and proteins11. In addition to nanopores, the Drndić lab uses the TEMs in the NCF for structural, vibrational, and electronic characterization of materials. In one experiment, an in situ electrical TEM holder with built-in electrical feedthroughs was used to monitor the transport properties of graphene nanoribbons while simultaneously the TEM beam was used to cut the nanoribbons from widths of 100 nm down to a few nanometers. In another, broad illumination of monolayer of MoS2 selectively removed sulfur atoms from the lattice, due to the high atomic number of molybdenum, allowing investigation of the dependence of the vibrational properties of monolayer MoS2 on concentration of sulfur vacancies. In another, the black phosphorus was sculpted into nanoribbons and nanopores.

Mid-Atlantic Cleanroom Managers Meeting In April 2016, the Singh Center hosted the first meeting of the Mid-Atlantic Cleanroom Managers. More than (20) universities and government laboratories and (45) staff members attended this event. The purpose of the meeting was to establish regional network contacts and understand each site’s strengths. This is an important exercise since the Mid-Atlantic region (from southern NY to DC) possesses the Nation’s highest density of nanotech facilities. Networking at the regional level and leveraging one another’s capabilities will strengthen the Singh Center’s presence in this technically rich area. Each site provided an overview of its capabilities, numbers of staff and equipment strengths. We agreed to meet every six months, rotating from site-to-site, exchanging best practices. A future meeting was planned for mid-October, 2016 at the Singh Center, where we will focus on deposition and etching equipment/processes and establishing a “sister schools” program within the region, allowing schools with similar size facilities, operating budgets, etc., to share information relevant to their programs.

Wednesday Open Process Sessions Each Wednesday, Singh Center staff members hold an open forum for users in the Penn fabrication community. The primary purpose of the event is assembling Singh Center staff with researchers to offer solutions to their fabrication problems, ranging from simple devices to complex multi-level process integration issues. It also allows researchers with limited background in fabrication to learn how staff and their community peers design devices and work through the challenges of device fabrication. This has proven to be a lively session each week that attracts 5-10 researchers and 3-4 staff members. An interesting observation among staff is how nearly all participants remain in the room for the multi-hour session, contributing to and learning from others in the Penn fabrication community.

2015-2016 Initiatives Research Outreach

Microfluidics Workshops Staff members from the Singh Center continue to host monthly Microfluidic Workshops as a form of outreach to local university medical schools (Penn, Drexel, Temple, Jefferson and Cooper). Outreach efforts are less targeted at MD programs (clinically driven), but more targeted at MD/PhD (research driven) programs where students and researchers are more likely to deploy lab-on-chip devices. Eric Johnston, who has been a staff member at Penn for twenty years, manages these engagements. Microfluidic workshops take place in the Singh Center’s Soft Lithography cleanroom. The Soft Lithography cleanroom is a class 10,000 space that adjoins the main class 100 cleanroom. Gowning requirements are less stringent in the Soft Lithography cleanroom, recognizing the reduced (but nonzero) need for particulate control in soft lithography, as well as in an attempt to make this facility more accessible to nontraditional users than the standard fabrication facility. It has been our observation that life science researchers are more likely to use our facilities when minimal gowning is required. Each month, approximately 8 researchers enroll in a six-hour session that consists of lectures and hands-on device fabrication. Typically, each researcher brings a device design with them, from which staff fabricate prototype mold inserts in advance. For researchers who do not have a design at hand, they select one from the laboratory’s internal library consisting of dozens of devices. The workshop participants then utilize the mold inserts to produce microfluidic devices based on their original designs. To date 95 people have gone through this program, with approximately 20% of the workshop participants going on to be users of the Singh Center.

Singh Center for Nanotechnology

Industrial Outreach Given the high density of regional bio-pharma companies, Singh Center staff began a roadshow to educate the regional community on diverse applications of microfluidics. A kick-off event was held at Dow Corporation and hosted by Dr. Alan Nakatani. The Singh Center’s fabrication capabilities were showcased in a local auditorium and simultaneously webcast to the entire corporation. Following the presentation, held at Dow’s Northeast Technology Center in Collegeville, PA, we participated in all-day meetings with staff from across the Dow Corporation as well as a site tour. During the day, Singh Staff members proposed hosting a customized microfluidics workshop for Dow’s senior researchers, which was held in April 2016.

In the process of working with Dow and other institutions, we have found that follow-up discussions/ consultations are required. Since we educate groups of people who are typically unfamiliar with designing lab-on-chip devices, our staff must engage them for months following a workshop. Our aim is to increase the likelihood that they will put microfluidics to practice in their laboratories. Interactions we have found to be fruitful in this regard include lively email exchanges, joint literature reviews, sketching devices with researchers and assisting with basic CAD and photomasks for microfabrication.

Since a key interest area of Dow is liquid materials, we customized an agenda around rheology techniques and their applications in microfluidics. During this event, we met 8 staff members from Burns, MN, Midland, MI and Collegeville, PA. The company has since returned to use the facility for fabrication and development of microfluidic devices for both low-pressure and highpressure applications. Similar engagements are being planned with a local Johnson & Johnson facility (Spring House, PA), as well as with Merck & Co (West Point, PA).

Internal Staff Development The Singh Center staff have deep expertise in micro- and nanofabrication, and will often work on the development of new processes that can then be placed at the service of users. This not only advances the state of the art of nanofabrication technology, but also provides continued opportunities for growth of the technical staff. Examples of staff-driven nanofabrication advances during the reporting period, have been published in Scholarly Commons.

Dissemination of Process Best Practices Through Scholarly Commons The Singh Center has published approximately 60 documents in the Penn Library System through Scholarly Commons http://repository.upenn.edu/ qnf/. As of June 2016, there have been nearly 5,800 downloads of these documents, covering topics from reactive ion etching, soft lithography, direct write lithography, equipment base lining and basic process knowledge. Downloads are worldwide (from every inhabited continent!), as indicated in the figure below, which shows this past week’s download map:

MEMS Devices for Teaching The objective of this project is to develop MEMS devices as course materials, publish on Scholarly Commons and share with other universities. Students will learn techniques to fabricate these devices such as photolithography, reactive ion etching, etc., their integration and device testing. Devices to be fabricated and tested include: Cantilever array with varying cantilever CDs (1μm-10μm), Comb drives with varying size (5μm gap, 10μm gap), Lateral beam resonators and Resistors & capacitors.

2016 NNCI REU Cohort

The Singh Center hosted six REU students for a 10-week summer research program. Students are hosted in faculty labs and work on projects that use the Singh Center’s Facilities. Students participate in weekly lecture series and complete assignments leading to a final oral presentation and written paper based on their summer research. The 2016 program ran from May 21 – August 5.

The names and institutions of the students that comprise the 2016 NNCI cohort are listed below. Three were rising seniors and three were rising juniors (one of these matriculated in August 2015, but will have the academic standing of a junior in Fall 2016). The average GPA for the cohort is 3.93 on a 4.0 scale. The academic majors represented in the cohort are: Physics (2), Chemical Engineering (with a double-major in French), Biomedical Engineering, Materials Science and Engineering, and Chemistry.

Programing for the Singh REU students included four French visiting summer students (3 master-level students and 1 undergraduate) who are at Penn to work in NSF PIRE-funded labs. Combining these two groups of students created a larger cohort for the final presentations and other programming. It also allowed both groups of students to benefit from sustained interactions with peers from another country.

Site Curricular Education The Singh Center for Nanotechnology feels that dissemination of societal and ethical implications of nanotechnology is very important, and have accommodated this in a new undergraduate course. The course ENGR 212, “Concepts in Micro- and Nanotechnology”, was developed and taught for the first time in Spring of 2016. This course, open to all undergraduate students at Penn, was offered through Penn’s Benjamin Franklin Scholars (BFS) program, and implemented as a BFS Seminar. As quoted from the BFS Program: “. . . Our goal for the Benjamin Franklin Seminars, the centerpiece of the Benjamin Franklin Scholars program, is to make them your most interesting and intellectually stimulating experiences at Penn. They are small classes that have fewer than 20 students, are designed to be intensive, and predicated on the idea that the students and faculty are jointly pursuing deeper discoveries through discussion and investigation. We hope that these courses will allow you to make intellectual and personal connections to both your peers and to faculty with similar interests to your own. The description of the course, as advertised to the students can be found below: Micro- and nanotechnology, applications of the science of the small and the very small, respectively, have quietly but completely transformed our lives. This course will explore some of the key concepts underpinning the fascinating world of micro- and nanotech. Through a combination of lecture and interactive seminar, and based on a minimal (but nonzero) amount of math and physics, students will be introduced to approaches to make and measure structures and devices on the micro and nano scales. The usefulness of these structures will be discussed in the context of nanotech applications ranging from size scales where everyday laws apply (such as the microelectromechanical systems in everyone’s cars and phones) to the size scales where the laws of the quantum world apply (such as quantum dots and nanotube transistors), enabling students to understand and intelligently discuss the scientific underpinnings of nanotechnology applications. Students will also be introduced to current societal impact and ethical issues of the growing use of nanotechnology (What do nanoparticles do to the environment? Can nanotech really help cure cancer? What happens if Moore’s Law for electronic systems, the driver of constant change for decades, comes to an end?), as well as examples of successful approaches and strategies to nanotechnology commercialization (How can I make money in nanotech?).

During the course, we will touch on the following topics: lithography, microscopy, top-down micro- and nanofabrication, the silicon transistor, microelectromechanical systems, the quantum world (low math version), low-dimensional systems, quantum dots, quantum computing, medical nanotechnology, commercialization of micro- and nanotechnology, and societal and ethical implications of micro- and nanotechnology. Fifteen students, representing three of Penn’s four undergraduate schools, registered for the course: four from the School of Arts and Sciences, eight from the School of Engineering, and three from the Wharton School of Business. Within the School of Arts and Sciences, biochemistry, math, and classical studies were represented, while within the School of Engineering, mechanical engineering, bioengineering, and computer engineering were represented. In addition to seminars led by the primary instructor, the students were exposed to guest lectures in business and investment as well as hands-on laboratory sessions.

Singh Computational Activities

Network Information Dissemination

The Singh Center for Nanotechnology offers advanced training in computational lithography for direct write electron beam and laser processes as well as full field illumination optical techniques. With the use of GenISys GmbH software suites (BEAMER, LAB, TRACER) we are able to simulate the aforementioned exposure processes as well as model electron-solid interactions through a full Monte Carlo EM simulation. Penn Staff members would happily volunteer to lead campus-wide efforts in computational lithography.

At the recent NNCI meeting, held in Salt Lake City during the UGIM conference (June 2016), Singh staff spoke with several universities about our Microfluidics Workshop and its recent successes. The team from Stanford Nano Shared Facilities (Carsen Kline and Dr. Tobi Beetz) seemed particularly interested in ways to further engage their medical school and demonstrate the usefulness of lab-on-chip devices. Subsequently, we explained our approach to meeting with the research arm of a medical school (e.g., MD/ PhD programs in neuroscience, immunology and cell biology) and shared our presentation slides, workshop formats as well as poster materials utilized when marketing to local medical schools.

Singh Center Research Collaboration We recently partnered with both the Cornell Nanoscale Facility (staff member: Vincent Genova) and the Harvard Center for Nanoscale Systems (staff member: Dr. Ling Xie) on a project for etching diamond waveguide structures. This is on behalf of Penn Engineering Professor Dr. Lee Bassett, a 2016 NSF Career Award recipient. When using an in-house ICP/RIE etching system, we experienced limitations in waveguide sidewall angle and are working to leverage our NNCI network resources to achieve near vertical sidewalls. The challenge is the aspect ratio of the waveguides (10:1), at 200 nm in width and 2μ in depth.

Dissemination of IRIS Management Software We have spent time showcasing our lab management application, IRIS, which is built on the Mendix agile development platform to several peer universities. This effort has demonstrated the value of working on a rapid development platform and the universities listed below are following in our footsteps. • Princeton University, who are building their own application based on the Penn model. • N.C. State, who are building applications to support executive education and were inspired by the development of IRIS at Penn. • U.C. San Diego, who previewed the Penn IRIS application and have decided to build a similar model. • Harvard University, who previewed our application and deeply appreciated its merits, but purchased on off-the-shelf product.

Initiatives on Cost Savings Presently, we purchase high quality materials in bulk to support smaller labs on campus. In time, this could expand to peer facilities, in the areas of chemicals, precious metals and daily-use items. As examples, we purchase gold at 25% below the low-volume rate; our glove pricing has decreased over $100 per case; safety equipment is costing us 50% less than the previous year. Through competitive bidding we have succeeded in dropping the gold price from $61.837 per gram at 5 9’s purity to $45.21 per gram at 5 9’s purity. This is based on a 200 g order (our standard) and now Penn is saving $3,325.40 on each order.

Through many conversations with our vendors, they have made their thoughts clear when working with universities: their experience is that academic institutions will never be able to purchase quantities large enough to receive best discounts. We tend to purchase on an as needed basis with little thought applied to buying in bulk. Within the university linkage from lab-to-lab can be optimized in terms of equipment sharing and mapping. By sharing vendors’ costing information with peer laboratories, we believe that we would begin developing meaningful relations. In doing so, we aim to share mundane information with our colleagues to obtain best pricing for consumables and equipment maintenance. As networked laboratories collaborate and leverage our combined purchasing power, 20-30% cost reductions should be realized on many items, not to mention allowing for rapid movement of materials from one lab to another. Why would vendors want to participate in this? It’s simple: they compete regionally with one another and if they have an agreement for selling e.g., gold to all Penn labs, then we all benefit. The vendors in turn, give up some of their margins, but make up the difference in much larger sales volumes.

Combined purchasing power, 20-30% cost reductions should be realized on many items, not to mention allowing for rapid movement of spare parts from one site to another.

Solid State Sensors, Actuators, and Microsystems Conference

Our first annual research day was held on October 27th 2015 and was attended by approximately 150 participants, including both current users as well as others in the community. Participants came from many universities and companies around the region to hear presentations on various aspects of nanotechnology. Presenters included Dr. Roy Olsson from DARPA, Dr. Kenneth Shephard from Columbia University, Dr. Daniel Solis from Bionano Genomics, and Ryan Mendoza, Sr. Vice President from Graphene Frontiers. In addition to the speaking engagements the day also consisted of a Nanotechnology Expo, Student Poster Presentations, and Facility Tours. This event allowed the current users of our facilities to showcase their work and to network with others, including the student and external business communities.

On June 5-9 2016, the 17th Annual Solid State Sensors, Actuators and Microsystems Conference took place at Hilton Head, South Carolina. The workshop provides a highly interactive forum for researchers to present and discuss recent advances in microfabrication technologies for sensing and actuation devices and microsystems for physical, chemical, and biological applications. Approximately 340 attendees in experimental micro- and nanotechnology attended the conference. Dr. Mark Allen, Director of the Singh Center for Nanotechnology was chair of this 2016 conference, and both the Singh Center as well as the NNCI Coordinating Office had information booths describing the range of services available at the network level.

Part of the success of this event was the ability to engage such a diverse array of participants, including many representatives of the nanotechnology industry as well as local businesses that helped sponsor the event. The addition of a vendor showcase to the student poster session created a very immersive environment that stimulated discussion between individuals at all levels.

Entrepreneurship and Innovation Open House Over the past few years there has been a significant push both at the University of Pennsylvania and throughout the Philadelphia region to foster technology innovation and encourage startup companies to both form and remain rooted in this area. As these aspirations align very well with our internal goals at the Singh Center, we have made significant efforts to engage the entrepreneurship community and to encourage them to utilize the resources that we have to offer. In an effort to kickoff this activity, we held an Entrepreneurship and Innovation Open House in February of 2015 that was attended by over (90) individuals ranging from student startup organizations and venture capitalist firms to the leaders of Technical.ly Philadelphia and members of the French Consulate. This event allowed us to directly engage with those involved in not only developing new technological advances, but also those who provide the financial, legal and business resources that allow those technological advances to succeed. We also utilized this event as a launching point for our Innovation Seed Grant Competition.

The Singh Center participated in two events at the 2016 Philadelphia Science Festival. In June of 2016, the Singh Center came together with other Makerspaces in the Philadelphia and New York City areas to discuss the formation of new technical ventures within the community. Held at the University City Science Center in Philadelphia, claimed as the nation’s largest Urban Incubator Space (and located within walking distance of the Singh Center), over 100 people gathered to hear Keynote discussions by Canary Security Systems, Orange Maker 3D Printing and Bon Bouton by Flextrapower and attend a small makerspace expo detailing some of the resources available throughout both New York City and Philadelphia.

The Singh Center participated in two events. One was the culminating Science Carnival (http://www. philasciencefestival.org/carnival), which featured 175 booths hosted by institutions and companies from throughout the region. In partnership with the Franklin Institute, Philadelphia’s Science Museum (https://www. fi.edu/), and a Materials Science group at Drexel University and at Penn, the Singh Center provided demos and volunteers for a nano-scale science booth (“What’s So Big About Super Small Science”). Students and faculty interacted with the public using NISENet (http://nisenet. org/) kits, including Thin Films, Nano Fabrics, Nano Food, Invisible Sunblock, Exploring Structures, and Electroplating. We also recruited two lab groups to share their demos on surface area of carbon nanomaterials and on quantum engineering. The second Philadelphia Science Festival event to which the Singh Center contributed was in partnership with the Penn School of Arts and Sciences Science Outreach Initiative. “Close up and Far Away” (http://www. philasciencefestival.org/event/175-close-up-and-faraway) provided facility tours and demos that showcased technologies for observing nanoparticles to galaxies. Nano-related demos were set up in the Singh Center lobby and staff provided tours of the Singh Center Facilities.
