The World’s Smallest Basketball, from the Basketball Capital of the World Laterally, the patterns are about 4-5 um. For comparison, a human hair is roughly 50 um.

Hence, the world’s smallest basketball was chiseled here in Storrs.

As the UConn basketball team progressed through their season, another team of Huskies was hard at work for the love of the game. One UConn College of Engineering department pushed the boundaries of innovation by creating the world’s smallest basketball.

Researchers from the materials science and engineering department, housed in the new Science 1 building, produced a basketball and Husky logo using the bestdepth-resolution nanolithography in the world.

“After we determined that our new technique worked, we wanted to do an eye-catching school spirit-related project,” said department head Bryan Huey. “A basketball and the Husky logo seemed to be a perfect way to celebrate UConn. It was fun watching our project take shape, and we couldn’t be more pleased with the results!”

The pictures were “carved” into a crystalline substrate.

The patterns are about 4-5 µm, with a depth of only 5 nm. Hence, the world’s smallest basketball was chiseled here in Storrs.

Huey’s team developed a technique to nanomachine patterns using Atomic Force Microscopy (AFM) and a unique iterative feedback approach. The materials science and engineering faculty and students

Besides basketball and logos, the technology is used by Huey's group for their pioneering Tomographic AFM work, studying future semiconductors, solar cells, metal alloys, and electromagnetic sensors—all with unprecedented nano-volumetric resolution.

developed nRasp over the last few years exclusively at UConn, improving existing AFM-based nanomachining.

“This technology expands on techniques developed in the last 25 years within materials science,” Huey said.

“The integrated feedback provides substantially more control, with an error of only 0.5 nm.”

The iterative feedback system continuously improves the nanomachined pattern structure. “It’s like a sculptor, working with finer and finer precision as the pattern takes shape,” Huey said.

The primary work involved conceptualizing the sequencing, writing custom code to control the microscope, and lots of engineering and iterations to achieve impressive nanopatterns and resolution.

Besides basketball and logos, Huey’s group uses the technology for Tomographic AFM work, studying future semiconductors, solar cells, metal alloys, and electromagnetic sensors with unprecedented nanovolumetric resolution. They also create microscopic dinosaurs.

In the future, they will use it for failure analysis, nanomanufacturing, and fabricating ultrafine features on difficult-to-manipulate materials. “School spirit runs deep within our schools and departments,” said Vice Provost for Graduate Education and Dean of the Graduate School Leslie Shor, an affiliated faculty member of the Institute of Materials Science. “Research innovation and providing a top-quality engineering education is our mission. We are lucky to be able to do that while still bleeding blue with pride for our top athletes.”

Exploring Heavy Metals Along the Ocean Floor UConn Associate Professor of Materials Science and Engineering, Xueju “Sophie” Wang, has received a 2024 Young Investigator Program (YIP) Award from the Office of Naval Research (ONR). Wang is one of 24 awardees representing 20 institutions in 16 states who will share nearly $18 million in funding to conduct innovative scientific research benefitting science and technology for the Department of the Navy.

Wang has received $750,000 for her project: “A soft intelligent robot for self-digging, multimodal sensing, and in situ marine sediment analysis.” The proposed robot, an octopus-shaped device, will have pliable arms equipped with multimodal flexible electronic sensors able to elongate and dig into ocean sediment. The robot will determine conditions such as temperature, pressure, and concentrations of heavy metals in real time

while on the ocean floor.

Ocean pollutants, such as heavy metals, persistent organic pollutants (POPs), and pharmaceuticals, are often stored in marine sediment, especially in regions with intense industrial activities.

Once accumulated, Associate Professor such pollutants pose Xueju "Sophie" Young significant threats to marine ecosystems and human health. Sediment analysis is crucial for assessing the marine environment.

The technology will address limitations in existing sediment analysis, which uses miniaturized electronic ocean sensors requiring high-pressure chambers and seals. Those devices also need larger power supplies and sensor systems.

The project builds on Wang’s prior work published in ACS Sensors. The 2021 paper introduces the concept of soft, pressure-tolerant, flexible

electronic sensors that can operate under large hydrostatic pressure and salinity environments.

The goal is to create a prototype for ocean testing.

“There is no device like ours that can dig into ocean sediment for in situ measurements,” says Wang.

Wang’s research crosses over biomedical engineering and materials science. Soft robotics and flexible electronic sensors have applications in agriculture, pharmaceuticals, and healthcare. In healthcare, Wang developed a smart bandage integrated with pressure sensors to speed up the healing of diabetic foot ulcers. Agricultural applications include a robot that monitors ground conditions.

Established in 1985, the ONR YIP is one of the nation’s oldest and most selective basicresearch, early-career awards in science and technology. Its purpose is to fund tenure-track academic researchers whose scientific pursuits show outstanding promise for supporting the Department of Defense.

The 2024 YIP awardees were chosen from more than 220 applicants. Wang’s fellow recipients include researchers from Stanford University, Columbia University, Brown University, and

Jankovic’s research is MSE Associate Professor closely interconnected with her teaching, in which she uses creative ways to inspire students to learn. These methods include ideation, design and building of the UConn STEAM Tree, implementing of entrepreneurship aspects in engineering classes, and offering research experiences to undergrads in her lab. Jankovic’s friendly and inclusive teaching style is appreciated by her students, as stated in one of the student support letters. MSE undergrad Jaclyn Grace wrote, “Within my four years at UConn, I have yet to find another professor who loves and cares about each and every one of their students as much as Professor Jankovic. Lectures are tailored to the individual learning styles of those in her class, including having an online synchronous option for students who are traveling or sick, no questions asked.”

When asked how she feels upon receiving this award, Jankovic said that it means a lot to her. “I really care about how students experience learning – for me it is a holistic experience. Students need to be inspired, to enjoy the process, and to trust the instructor. It’s then that learning comes naturally.”

The extreme resolution possible with UConn’s novel Tomographic AFM is demonstrated by the full 3-D map of ferroelectric domains (color, top), and magnified image just of domain walls (base), for a crystal of multiferroic ErMnO3 reported in the Advanced Materials publication.

This work incorporated 403 raw images, 633 million total data voxels, and depth resolution better than 5 nm.

UConn Signs Contract with Air Force Research Laboratory The $10.5 million contract supports research on manufacturing challenges for high-temperature applications together with RTX as industry partner.

UConn recently received $10.5 million from the Air Force Research Laboratory (AFRL) for research on high-temperature materials and manufacturing processes. The funding will allow a team of seven faculty members from Materials Science and Engineering (Professors Aindow, Alpay, Frame, and Hebert), Civil and Environmental Engineering (Professor Kim), Mechanical Engineering (Professor Bilal), and Chemistry (Professor Suib) along with postdoctoral associates and graduate assistants to address challenges in the manufacturing of aerial systems intended to fly at high speed. Much of the four-year research project will focus on welding-related challenges for high-temperature metallic materials that are used for structures exposed to high speeds. The UConn team will combine experimental and theoretical approaches to help their collaborator, RTX, advance their manufacturing solutions. Additional project tasks address the behavior of non-metallic high-temperature materials under different processing and service conditions, additive manufacturing of high-temperature refractory metals, and the design and processing of metamaterials.

These metamaterials are designed to change heatand electro-magnetic fields in and around structures and are considered to advance the thermal management of high-temperature structures.

The new AFRL project comes at the heels of previous and ongoing AFRL projects for UConn totaling over $15 million that involve over 15 faculty members from the Colleges of Engineering and Letters and Science with over 25 graduate students and postdoctoral associates. Covering research from functional materials and photonics to casting, welding, and additive manufacturing, the UConn team has established itself as a valuable partner for the AFRL and key industry partners, for example, Pratt & Whitney and Collins Aerospace.

Professor Rainer Hebert says of the contract, “The AFRL funding enables the UConn team to pursue materials processing research with a strong focus on industry and government relevance. Students and postdoctoral associates working on the project see firsthand how their research translates to industry. This insight will help in preparing a workforce that can pursue research excellence with a keen sense of the needs and constraints of industrial applications.”

ADVANCING DIVERSITY

A Materials Student’s Mission to Increase Latino Engagement in STEM Ph.D. student Luis Ortiz's passion for materials science was ignited during his undergraduate years at the Universidad de Puerto Rico - Humacao, where he was involved in research focused on physics applied to electronics. He revealed, "In my Applied Physics department in Puerto Rico, we have a program mainly focused on materials research. Based on my experience there, I fell in love with the material science field and decided to pursue my graduate studies in this area."

Ortiz became exposed to the UConn MSE program through various fellowships he applied to throughout his undergraduate years. He revealed, “We didn't have much information about UConn in Puerto Rico.

As a minority student, I decided to apply for fellowship opportunities that could help me succeed in graduate school at universities in the USA. I also applied to this specific program called the Bridge to the Doctorate Louis Stokes Alliance for Minority Participation while I was an undergraduate student. This is a two-year fellowship that helps you bridge between undergraduate and graduate school, and they supported me through the start of my Ph.D. They have a network of universities inside the program, and UConn was one of the listed colleges.”

During the two-year fellowship, Ortiz was introduced to Professor Bryan Huey, who currently heads the MSE department and serves as his advisor. Luis admits feeling supported by Professor Huey and the other department faculty members. He remarked, “Many people here are willing to mentor students and see us become better professionals. My advisor has been one of them.” Ortiz acknowledged the support he receives from MSE faculty members to pursue his dreams and their confidence in his ability to achieve them. “I feel supported and validated in terms of how we pursue our path and work to achieve our goals,” he said.

Currently, Ortiz is conducting research on material properties, primarily using the Atomic Force Microscope (AFM) and its advanced extensions. In simpler terms, he explains, “I'm currently working on an alternative 11

type of solar cells.

These ‘Halide Perovskite’ systems use far less energy and raw materials to manufacture but can be just as efficient.

However, the main problem that they have is stability. No one has yet figured out how to make them last longer. So, everyone is competing to understand and eventually sell the best product.”

Luis Ortiz, MSE graduate student

When explaining how his research transfers and relates to the real world, Ortiz stated, “Traditional silicon solar cells have been around for years. We know how they work, and they have been in the market for decades now. However, they are still relatively expensive. With this research we are really part of a worldwide effort to develop this new kind of solar cell that should be up to five times cheaper than traditional panels. This would make alternative renewable energy systems so much more accessible in the future.”

Professor Huey notes, “Luis is studying the performance of this new solar cell technology at one of the finest levels of resolution in the world. It is groundbreaking work and required him to develop new protocols to learn the most from his incredibly challenging measurements.

This is only one of Luis’ great strengths, though—he’s also a great speaker, passionate about expanding diversity in engineering, and so Luis has also become a wonderful ambassador for UConn Engineering to help us inspire and recruit future students especially from institutions back home in Puerto Rico.”

Ortiz participated in the Research Experiences for Undergraduates (REU) program for four consecutive summers, gaining knowledge and skills that shaped him into a scholar and problem solver. His journey began at NASA, where he studied heliophysics, focusing on solar radiation's effects on space electronics and astronaut health. The next summer at Michigan State University, he delved into Nuclear Physics, exploring fundamental forces and innovative nuclear energy solutions. At Princeton University, Ortiz contributed to developing testing mechanisms for functional electronics. Finally,

at Brigham Young University, he researched magnetic properties in data storage applications, a key area in the MSE field.

Reminiscing on these experiences, Ortiz expressed with gratitude, “They all gave me the tools I needed to understand what I wanted to do next and expand my knowledge in some other areas too. For example, we do a lot of data processing and coding in our lab.

This is something I did during my first two internships as well. All of these experiences helped me forge the professional who I have become today.” In addition to these opportunities, Ortiz also had a four-month internship at Mott Corporation in 2022 as a Research and Development Intern.

In addition to his academic pursuits, Ortiz was very involved with the Material Research Society (MRS) University Chapter at UConn and was elected President by its student members for 2021-2022. And, as his advisor noted earlier, Luis was invited by the UConn College of Engineering to join in several trips to Puerto Rico for student recruiting. He got to visit several universities throughout Puerto Rico, engaging with students and professors. They set up booths on campuses and offered interactive class participation activities to introduce the students to topics often discussed at UConn. Ortiz asserts that his main goal for participating in this program is to expose students in Puerto Rico to opportunities and resources and confirm that they can receive economic and academic support to attend graduate school.

division and earning the UConn Material Science and Engineering Outstanding Leadership Award in 2022.

Reflecting on the latter recognition, Luis affirmed, “This was a great opportunity to develop my leadership skills and be exposed to other people involved in materials research and other organizations. I wanted to get exposure with those beyond UConn, do more networking, build my confidence in talking to people, and improve many other life skills.” As a scholar, Ortiz, in collaboration with others, has published three papers and submitted two, with two more currently in the process of being submitted.

After completing his Ph.D., Ortiz hopes to continue working in research and emerge as a leader in a technologically advanced field. He credits UConn for preparing him for his future career. He claimed, “I want to work in an industry lab, and I also want to use my skills to lead others and have a research group in the future.”

Ortiz emphasized one word when asked about advice he would give students aspiring to pursue MSE research.

He said, “Do your research to understand exactly what you're getting into. Something very good about materials science and engineering is that this is a very multidisciplinary field. So, just get involved in reading and understanding the path that you want to follow.

Get exposed, talk to people, talk to your advisors, professors, and other grad students, and then dive in.”

Ortiz wants to be seen as a testament to the opportunities that arise when support is provided. He professed, “A lot of people don't know that they can get funded while pursuing their graduate degrees. This is an important aspect to consider in order to encourage other people to pursue this path, especially those who do not have resources of their own. I also think there should be more minority participation in graduate programs to show diverse representation in grad school. For many groups, including international students, people of color, and Latinos, this is the best way to let them know earning an advanced degree at UConn or elsewhere is possible, and that a support community will be available too. We are all striving for the best version of ourselves to make a change in society and contribute to a better future.”

Ortiz has seen academic success translate into multiple accolades, including winning 1st place in the 2023 College of Engineering Poster Presentation for the MSE

Find What Research Is the Best Fit For You

Cassidy Atkinson, a final year materials science and engineering (MSE) Ph.D. candidate, discovered her passion for MSE during her undergraduate college tours because of its wide-ranging applications across various fields. “I like how broad a field it is because it is truly relating to everything, but everyone’s research is so niche.”

Throughout her time at UConn, Atkinson had several inspirational professors. “Professor Alpay and Professor Frame have stood out to me as being professors that I look up to and I feel comfortable having a conversation with, whether research related or not. Other faculty members in the department have also taught me a lot, including Professors Nakhmanson, Goberman, Brody, and Lee. They are all very knowledgeable in their fields and I think their enthusiasm for it comes off clearly in the way they teach and interact with their students.”

During her sophomore year of undergrad, Atkinson received a Summer Undergraduate Research Fund (SURF) award, a competitive accolade where applicants propose summer research projects. Her winning project, titled Chemical Trends in Al-Cu and Al-Ag Interfaces from First-principles Theory, was guided by her faculty mentor Professor Pamir Alpay.

Also during her undergraduate studies, Atkinson participated in multiple projects with the Army Research Laboratory (ARL), an experience that she credits with 13

| UConn - Department of Materials Science and Engineering, 2024

shaping her decision to pursue a Ph.D. “I already knew that I wanted to pursue higher education. Being at the research lab and talking to the professional researchers there helped me realize that it would be beneficial for me personally to go directly to graduate school after finishing undergrad. I think if I had taken a break and gone into industry instead, I would’ve had a difficult time going back to school.”

Atkinson proceeded to delve into her past research endeavors, detailing how they paved the way for the research she currently conducts as a grad student. “I started doing density functional theory (DFT) as an undergrad and I really enjoyed doing computational research, so I decided to keep pursuing it as my graduate research. I wanted to learn more about the computational side of things for my Ph.D. A lot of my current research focuses on seeing the impact of impurities on properties and structural stability of various material systems. I mostly focus on ceramics, but am also working on a side project looking at the effects of impurities on aluminum.”

Atkinson's research has resulted in three publications on topics such as silicon carbide grain boundaries, enhancing the electro-optic effect in HfO2 and ZrO2, and analyzing the local atomic environment in calcium lanthanum sulfide ceramics. Additionally, she is currently working on two more papers focusing on calcium lanthanum sulfide and aluminum impurities.

In 2023, Atkinson embarked on a six-month research project in France through the Chateaubriand Fellowship. This prestigious grant, awarded by the embassy of France in the United States, aims to support outstanding Ph.D. students from American universities pursuing research opportunities in France.

“It was a great experience to see how research is done in a different country. I really enjoyed the people that I worked with and the environment that I was in.

It helped me grow as a researcher and learn how to communicate my own research more clearly.”

When asked what advice she has for any current MSE students, Atkinson said, “It is important to get involved in research. If a professor is doing research that interests you, reach out to them and see if there is any opportunity for you to join their lab. Don’t be afraid to reach out to multiple professors and find what research is the best fit for you.”

STUDENT ADVOCACY IN ACTION

MSE Delegation’s Impactful Congressional Visits Day Five materials science and engineering (MSE) undergraduate students from UConn packed their bags and headed to Washington, DC, in April for ‘Congressional Visits Day.’ This event, organized by Material Advantage – the student association for the four main MSE professional societies (ASM International, TMS, AIST, and ACerS) – brought together students from across the nation. Leading the UCMA (UConn Material Advantage Student Chapter) delegation was Jaclyn Grace (’24), the outgoing UCMA president, accompanied by the newly elected executive board members Benjamin Gwinnell (’25), Connor Storicks (’26), Thatcher Slocum (’28), and Rachel Harris (’26).

“The goal of the event is to speak to Congressional Legislators and their teams about the importance of research in materials science, engineering and manufacturing, and the recent cut in R&D (research and development) funding,” Senior MSE major, Jaclyn Grace, explained. “There was a cut of over 6% federally, which greatly impacts the colleges and universities in our country. We were not lobbying for Connecticut specifically, but for R&D and educational funding for STEM in general.”

During the event, students had quick sit-downs with staffers to talk about how federal funding hits home for them. Some meetings were as short as ten minutes in duration, but Jaclyn felt like the response rate was high.

“Our meetings mostly consisted of staffers telling us that they will look for letters and bills that support our cause, and will try to move them up on their lists of importance,” she said.

UConn’s meetings were with John Larson (CT 1), Rosa DeLauro (CT 3), Richard Blumenthal (CT Senate), and Andy Kim (NJ 3). “I think what stood out to me most was how kind the staffers are. Even though they are busy and overbooked, they faced us with kindness and genuinely listened to what we were saying. Most didn’t know what MSE was, and being able to speak about our individual experiences was important.”

Jaclyn shared that the highlight of the event was an unexpected meeting with Congressman Joe Courtney.

From left: Jaclyn Grace, Ben Gwinnell, Rachel Harris, with Rep. Joe Courtney (2nd from right) “We ended up meeting him completely by surprise, as we initially had a meeting with one of his staffers. Our meeting took place in his office, so upon his return, he joined our meeting. Getting to meet with the actual Congresspeople and Senators is not common during this event since they are so busy, so it was a welcome surprise. He was very excited to talk to us about submarines, welding, and manufacturing. Since Rachel, Ben, and myself are all from District 2, our meeting felt extremely personal. He brought up the importance of educational funding in each of our hometowns. In my case specifically, he told me about his recent visit to my prior high school–Westbrook High. They have become a golden standard of tailoring their education to learning styles of many different students and providing alternative opportunities through a partnership with General Dynamics Electric Boat. It showed that he truly cares about the people he is representing.”

Overall, Jaclyn summarized Congressional Visits Day not as a conference, but an opportunity. “The event was very self-motivated, as the total impact of the day was based on the students’ proactivity and personal experiences that they shared. I think everyone should participate in a congressional visit if they get the chance, because it’s important to fight for the things that are personally meaningful. It doesn’t necessarily have to be education or R&D, but the more that elected officials hear from their constituents about the things we’re passionate about, the more likely that our issues are to be addressed. You never know how big of an impact you can have, but you do know that nothing will ever change if you don’t make an effort.” mse.engr.uconn.edu

A Look into the Life of an IPOEF Inspiration Award Winner When Audrey Larson was sixteen years old, she received her first patent for a system that helped reduce carbon emissions from cars on highways. At seventeen years old, she received her second patent - this one for a bullet proof barrier to help protect students during the event of a school shooting.

In high school, Audrey started the Inventors Club through the CT Invention Convention. “It was a response to COVID-19,” she explained. “During the pandemic student inventors around the state who would normally work on their inventions in school lost the ability to do so. The Inventors Club was an afterschool opportunity for those students to connect virtually and work on their inventions together.”

At UConn, Audrey is an undergraduate who is doublemajoring in materials science and engineering (MSE) and civil engineering. “My reasoning for choosing MSE stems from my interest in engineering, which started with participation in the CT Invention Convention program. This program introduced me to the career of engineering while I was in elementary school, and it was then that I realized I wanted to be an engineer. My specific interest in MSE came in high school when I did the Explore Engineering (E2) summer camp at UConn, which allowed me to learn about different engineering majors. Up until that point in my life I had no idea MSE even existed, and it was after this that I knew MSE was for me. It blends my love of engineering with chemistry and allows me to be interdisciplinary.”

UConn’s research opportunities are a large part of why Audrey chose to attend. “I knew UConn is an R1 university and I really loved the idea of doing research while in school. This hope ended up coming true, as I began to do research the summer before my freshman year - before I was even a husky!”

Audrey is most interested in additive manufacturing (3D printing) and how materials science plays into that field. Her favorite class so far has been Professor Rainer Hebert’s thermodynamics class. “The course material was so fun, and he used real world examples to explain the concepts, which made it much easier to grasp.”

It was in Audrey’s dorm room freshman year that she started her first of two companies - Unfolded and Geomate.

“Unfolded was formed to give student artists a platform.

Through the company we sell sustainable shirts and jewelry that have the designs of myself, my business partner, and other UConn students who we contract out to create designs. Geomate is an earlier stage venture that was founded out of the UConn Student Health and Wellness program, Innovate Wellness.

Geomate is an app that is made to help students feel safer when they are walking alone at night on campus.”

In 2023 Audrey was the recipient of the IPO Education Foundation (IPOEF) Inspiration Award, which recognizes individuals who have MSE undergraduate student Audrey Larson at the NASA Space Center in Houston, TX. made a significant contribution by promoting and championing Houston. She worked in the Thermal Design Branch on intellectual property rights for, and on behalf of, heat shield materials for the Artemis Program and other members of underrepresented communities. “I was space projects. Audrey appreciated the mix of hands-on absolutely honored to earn the award from IPOEF for lab work and analytical tasks, as well as the opportunity my work in intellectual property (IP). I have always tried to rotate through different departments and collaborate to support others in their pursuit of IP and to help make with commercial partners like SpaceX and Sierra Space. way for other students like me who are interested in "It challenged me in many ways both personally and protecting their IP. Through the CT Invention Convention professionally, but overall, taking a semester off, moving and the years I worked with them, I have developed to a different place, and having a co-op experience a love for inventing and for meeting and working with like this is absolutely something I would recommend other student inventors like myself.” to other students," she said. Audrey looks forward to Department Head Bryan Huey notes: “Audrey’s passion returning to NASA next summer, where she will be about materials, and entrepreneurial successes, are working in the Active Thermal Design and Life Support clearly extraordinary. They’re also representative of a Systems branch to learn more about active methods of consistent theme among our majors, alumni, and faculty, thermal protection and regulation on spacecraft. since we are continually discovering new materials to When asked how UConn’s MSE department has helped improve engineered designs that impact our everyday her work towards her career goals, Audrey said, “UConn lives. In fact, at that same IPOEF awards ceremony, MSE continues to have a curriculum that lets its students Professor Cato Laurencin was recognized as their explore all areas of MSE, from biomaterials to energy. inventor of the year!”

This has helped me pinpoint my interests in a positive During the spring semester and summer, Audrey way. The MSE environment here is very tight knit, and I completed a co-op at NASA’s Johnson Space Center in know I can always rely on my classmates!”

MSE Alumna Recognized by The Journal of Blacks in Higher Education

MSE alumna Sharon Uwanyuze ’23 Ph.D. was featured on The Journal of Blacks in Higher Education's list of ‘Five Black Scholars Who Are Taking on New Assignments at Universities.’ Uwanyuze is now an assistant teaching professor of materials science and engineering at Missouri University of Science and Technology, specializing in metallurgical engineering with expertise in non-ferrous alloys, metalmold reactions, and investment casting.

At UConn, Uwanyuze earned her Ph.D. in materials science and engineering in 2023 and completed a Graduate Certificate in College Instruction in 2022.

She was actively involved on campus, serving as President of Grad Black Stem, the UConn chapter of the National Society of Black Engineers, and participating in the His Branches Adventurer Club, a local children's program.

Uwanyuze received the UConn MSE Teaching Excellence Award and the General Electric (GE) Fellowship, recognizing her contributions and innovation in teaching. Department Head Bryan Huey says, “Sharon impressed many of us throughout her time in UConn MSE. I’m especially pleased that she is continuing in academics, because I’m sure she will be an inspiration to her current and future students.

This is yet another example of the incredible impact our alumni make beyond Storrs after they graduate.”

| UConn - Department of Materials Science and Engineering, 2024

From Formula 1 to Nanocalorimetry MSE alumna Lakshmi Ravi Narayan has known she’s wanted to be an engineer since she was eight years old. “I was watching Formula 1 races and thinking about how fascinating the jobs were in the garages and pit walls. As I progressed in my education and career, I became interested in manufacturing processes and the underlying science behind them, which is how I found myself in the field of materials science and engineering (MSE).”

Lakshmi received her Ph.D. in MSE in 2022, and mentioned multiple UConn professors that inspired her.

“My Ph.D. advisor, Professor Rainer Hebert, showed me that research is not about the number of publications, but rather the quality and value of the work that we do. He also taught me that playing by the rules is more important than gaming the system, and that a good balance of work and life is necessary. I now know that a supervisor should be understanding, flexible, and kind, because that type of an environment brings out the best in people.”

“Professor Lesley Frame is the kind of researcher I hope to be,” Lakshmi continued. “She has such a depth and breadth of knowledge that one comes out of an interaction with her having learned so much and with renewed insight into one’s own work. She is able to see so much in a piece of data and can foresee so much even before you complete an experiment.”

Lakshmi then spoke highly of Professor Harold Brody.

“He has always made me feel good about myself – even when I was a half-baked experimentalist – and that helped me a lot during my Ph.D. work. I am proud to have had one of the biggest names in the field on my committee, but I will value him most for always building me up.”

Currently, Lakshmi works for the National Institute of Standards and Technology (NIST) as a foreign guest researcher. “NIST has a global reputation that is unmatched, particularly in the field of metallurgy and thermal analysis – my chosen areas of research. When I would use a method or technique and cite a NIST work for it, Professor Hebert never questioned it, and I wanted to go work at the place where the quality of research is of that caliber.”

When asked what her job typically involves, Lakshmi said, “I am at the postdoctoral stage of my career, which varies in nature from place to place. At NIST, some postdocs go on to academia after a couple of years, and their projects are short-term, but others who intend to stay pick up longer term projects. My group at NIST is now working on a few CHIPS-funded projects, and my project involves applying thermal analysis techniques to semiconductor devices – scaling down calorimetry to the nano-scale. We make the chips on which the experiment runs, the associated electronics and instrumentation, and the Labview codes to run them. Then there’s the experiment itself. This is a rather uphill path for me as I had never made chips before or encountered circuits beyond an undergraduate textbook.”

Lakshmi’s current work is something called the Nanocalorimetry project. “What we do is develop

thermal analysis techniques at the nanoscale, to study the effect of rapid thermal cycling on the performance of semiconductor materials and devices. You know when you’re scrolling through instagram and your phone gets too hot, until one day it dies? That’s what we’re working to prevent.”

“It is definitely a privilege to work alongside some of the most brilliant people,” Lakshmi said regarding her favorite part of her job. “In fact, as I type this, there is a Nobel laureate in the building across the courtyard!

While very arduous, the huge upskill from what I was doing before to what I can do now is very satisfying. It is indeed rare to be able to do fundamental research with all the resources at one’s disposal.”

When asked about the most difficult part of her job, Lakshmi explained, “Making chips is physically exhausting, and trying to keep up with very brilliant people in things like electronics and circuitry that are outside my ken can be hard on the spirit – but I try to focus on the kind of researcher I am going to be. That makes it alright.”

Lakshmi also mentioned several ways that interested individuals could get involved at NIST. “NIST is always seeking postdocs, but often the positions are not posted formally. That is because they can be tweaked to suit the interests of the applicant. I encourage Ph.D. students to directly contact the person at NIST whose work seems interesting. The NRC program is open to citizens and there are postings on the website, but there are other means to be hired as well. CHIPS is looking for many postdocs to hire right away and is open to everyone. I also recommend the Summer Undergraduate Research Fellowship (SURF) to undergraduates who would like to experience a large lab and do hands-on work, but with a healthy side of fun.”

Networking with alumni can be incredibly important for students of any major. It can provide amazing opportunities, open doors that were previously closed, and help pave the path to the career a student is striving for.

Lakshmi’s final words of advice to current and prospective MSE students are as follows: “If you are good at it, you can make a living out of it. If you are comfortable with math and don’t mind getting your hands dirty, MSE is for you.”

How to Have Fun in a Ph.D. Program

“Believe it or not, I decided to be a materials scientist when I was ten,” said Gyuho Song, UConn MSE alum (‘20). “To be precise, I decided to 'invent a new material' after watching an animation about a miniature car on TV. It was a fictional unbreakableyet-strong ceramic and I thought it was really cool.

(I didn`t know there is a trade-off between ductility and strength when I was ten - I learned that as an undergraduate.) From there, I fell in love with physics and math in high school, went to study materials science and engineering (MSE) in undergrad, and came to the US for an MSE master`s degree in 2014.”

When asked which professors inspired him the most during his time at UConn, Song listed four.

Professor Bryan Huey, Song remembered, was kind to all. Song was a self-funding student, looking everywhere for research assistance. When Professor Huey got funding for a new project, he called Song to ask if he was interested in joining the team.

Song credits that opportunity as the reason he managed to continue his studies and get to where he is today. Professor Avinash Dongare’s teaching was so incredible, Song said, that he could not stop studying and playing with what he had learned from the course. Professor Dongare helped him to see the world completely differently, and is the reason he began to learn computation, machine learning, and cloud computing. Professor George Rossetti’s class, Song added, showed him materials science on a completely different level than what he was used to, and had him beginning to think about how amazing MSE knowledge can be in the real-world industry.

Professor Seok-Woo Lee, Song’s advisor, was the best fit for him. As a curious person, Song likes to try new things, and Professor Lee allowed him to do so - as long as he got his work done. With Professor Lee’s patience and guidance, they even turned one of Song’s curiosity-driven projects into a publication.

MSE alumnus Gyuho Song (’20), Ph.D., senior engineer for Frore Systems, adjusting a grip for the mechanical test of materials.

Professor Lee speaks highly of his experience advising Song. “Gyuho is a very inquisitive person who was always willing to learn new things. He always had many research ideas and did not hesitate to share and discuss them with me. I enjoyed talking with him a lot. Even though he was interested in many different topics, he never lost his deep focus on his research. I feel that Gyuho is a born-to-be researcher.”

Currently, Song works as a senior engineer for Frore Systems in San Jose, California. “While at UConn, I attended many entrepreneurship seminars and was fascinated by many startups. As a materials scientist and engineer, Frore being a Silicon Valley tech startup was too awesome not to jump on. I considered it an adventure because the company was still in stealth mode when I applied, and there was not much information about it online.”

“At Frore Systems, like any startup, new problems pop up everywhere, out of nowhere, everyday,” Song explained. “My job is to figure things out - to find a way to investigate the root cause. On top of that, it’s a very fast-paced environment. When we have a meeting at 10am and I am assigned to figure out a problem, I read papers and study theories, put things together, and make sure to have some preliminary experimental data gathered by 4pm the same day.

When it works, it feels good to be a scientist! When it doesn't, I miss all the resources available at UConn (SEM, TEM, XRD, nanoindentation, etc.).”

One of Song’s recent accomplishments has been writing and publishing a book, Ph.D. Unlocked: A Real-World Guide to Take You From Funding for School to Your First Job Offer as a Doctorate. “I wrote the book after moving to Silicon Valley and meeting lots of super-smart Ph.D. holders. When I talked to them, a large number did not seem to have had much fun during their Ph.D. programs. Because I personally had had so much fun and loved every moment at UConn, I decided to write a book about how to make the most out of a Ph.D. program.”

Song listed three kinds of people who he hopes will be impacted by his book. The first group is not only undergraduates, but also people who are already working for companies - those that have a passion for learning and thinking in depth. He wants them to know that a Ph.D. program is not a scary thing; it can be really fun, and truly transformative. Second, he hopes his book reaches people who may be struggling to afford their education. Song worked to save money for graduate school and feared it wouldn’t be enough. He hopes to share with that specific audience that it is possible if you know where to look for funding opportunities. Lastly, he hopes to reach current Ph.D. students who are struggling with

their research, writing, or job searches. Song said that he was incredibly lucky to have great advisors and faculty around him, but still saw other students struggling. On top of that, he mentioned that job search was brutal - as is the experience for many students - but eventually, Cover of Gyuho Song’s new book, good things titled Ph.D. Unlocked: A Real-World happened.

Guide to take you from Funding for He hopes School to Your First Job Offer as a Doctorate. to share that positive energy with students who are currently encountering the same obstacles.

When asked what advice he has for current or prospective materials science students, Song said, “The more advanced work gets, the more collaboration is required. If you like learning and understanding the world more than meets the eye, consider a Ph.D. in MSE. I enjoyed studying MSE at undergrad, but things got so much deeper, more extensive, and - most importantly - more fun at graduate school. You never know what you may end up falling in love with once you are there.”

“I love UConn,” Song said by way of final thoughts. “I really want to do anything I can to help the students there and make the university proud. UConn is my home - it’s where I grew as both a scientist and a person, and met some amazing people (including my wife). If anyone has questions about graduate school, working at a startup, Silicon Valley, or anything at all, they can reach out to me via email or LinkedIn. They will get a response from me in a day.”

From MSE Graduate to Professor in Materials Science Innovation UConn alum Rohit Batra suspects that he may have been unconsciously influenced to enter the field of materials science and engineering (MSE) by his father having owned a small electroplating plant when he was a child. “Seeing him work around several day-to-day items based on metals, and processing them to appear fancy and useful, did impact my decision.”

Batra received his Bachelor of Technology in metallurgical and materials engineering from the Indian Institute of Technology, Roorkee in 2011 before deciding to pursue his Ph.D. at UConn. “A couple of seniors in my undergraduate institute were pursuing their Ph.D. under Professor Rampi Ramprasad at UConn. Before even applying, I talked to them and learned about their experiences and possible future opportunities. They motivated me to apply under Professor Ramprasad as well. After my undergraduate and before starting my Ph.D. I did explore industry for around three years.

However, I did not enjoy my work and decided to go for a Ph.D. instead—where I could gain more technical knowledge and train myself to solve more technically challenging problems.”

Batra holds Professor Ramprasad, his Ph.D. advisor who now teaches at Georgia Tech, in very high regard, along with several other faculty members. “I found professors at UConn to be quite approachable, knowledgeable, and very helpful. I had good discussions with several of them both on the professional and personal level.”

During the pursuit of his Ph.D., Batra enjoyed learning different skill sets and using them to solve challenging technical problems. “I picked up computational methods to simulate materials (such as DFT, MD simulations) as well as machine learning based methods. I enjoyed how I can use these methods to understand some of the mysteries of nature - the intricate interactions between atoms happening at the micro-scale but resulting in the macroscopic behavior that we see with our eyes.

I also loved how I can use these methods to design or discover new materials that can solve the demands of the future, such as generation or storage of clean energy, sustainable polymers, etc.”

25 | UConn - Department of Materials Science and Engineering, 2024

Professor Rohit Batra, UConn MSE alum (‘19) and current assistant professor at the Indian Institute of Technology, Madras.

Currently, Batra works as an assistant professor at the Indian Institute of Technology, Madras. He explained that his job involves three different realms of responsibility: teaching, research, and administration. “Under teaching, I teach core courses (theory or labs) and also design new elective courses that allow students to be more aware of the current research activities or perhaps become more employable. For instance, after joining IIT Madras, I floated my elective course titled “Machine Learning in Materials Science”, in which I cover several aspects of how AI/ML methods are being used to accelerate the process of discovery and design of new materials for several applications. Under research, my job is to train students at various levels (Ph.D., MS, M.Tech, B.Tech) to carry out research projects. This involves meeting with them regularly and advising them on how to conduct research and how to communicate their results. This also involves traveling to conferences to communicate my research and find new projects and collaborations. Under administration, I perform several department or institute activities to ensure smooth functioning. For instance, I am part of a committee responsible for Ph.D./MS admissions interviews. We also have a facet regarding the mental well-being of our students, and as part of that I meet with about twenty students every month to listen to their various issues.”

Batra proceeded to explain his personal teaching style. “I like my classes to be interactive, and therefore, while teaching I pose lots of questions to the class. I only move forward with a topic after students answer my questions. I use a mixture of presentation slides, handwritten lecture notes, software programming codes, video links, etc. In my elective I do not conduct an exam but only grade based on project and assignments. I also conduct a few interesting and graded class competitions such as technical pictionary or buzzer games to make class fun. Students seem to enjoy activities like that a lot.”

At his institute, Batra leads a research group called The Materials Informatics Lab. “We try to use data driven methods coupled with materials computations to find new materials. Specifically, we develop ML/ AI methods to accelerate discovery of materials. For instance, we are working on a project to find new polymer electrolytes that have Li-ion conductivity and could possibly help resolve the safety issues concerning present Li-ion batteries in the market. In another project we used ML/AI methods to come up with a new class of non-intuitive and unusual peptide sequences that show b-sheet self-assembly. Such peptide materials could be useful for catalysis, drugdiscovery, or metal recovery applications. Similarly, we are working on projects that involve the discovery of high temperature shape memory alloys and AI-driven autonomous materials laboratory for thin films.”

When asked what the most rewarding part of his job is, Batra mentioned two different aspects. “Firstly, I feel very happy when my students get offers from a good industry or academic institute. I get to share their joy and that is one of the most rewarding experiences.

Second, when you do a good job as a professor, students really respect you from their heart. I also find it very rewarding when students genuinely respect you for the hard work you have put into their training.”

Batra then elaborated the impact of working with students on his personal research and outlook on life. “Teaching is the best form of learning. Because students are new and still learning, they ask questions from several different angles. This mere interaction with them forces you to think about technical concepts and research from several perspectives, which ultimately enhances your understanding of the topic and makes you a better researcher. I also

find it interesting that this job allows you to interact with students from various backgrounds, cultures, upbringings, and personalities. I would like to believe that closely interacting with such a diverse crowd makes you a more open, humble, and good human being.”

When asked what advice he has for current MSE students, Batra said the following: “There is a lot of scope in this field. There are many materials challenges that need to be solved to meet future energy and sustainability goals. Try your best to grasp the fundamental aspects of this field, to do projects in research groups that allow you to get hands-on experience on what research is being conducted and how the concepts you learn in your coursework are utilized. If possible, along with MSE also try to gain basic software programming and ML/AI knowledge.

These skills are becoming quite important and will allow you to do even better work in the field of MSE.” “Overall,” Batra concluded, “I really enjoyed my time at UConn. Some of the friends I made at this school are lifelong and I’m still in touch with them, even after moving to India.
