Twinkle Pandhi, a graduate student in the Micron School of Materials Science and Engineering received a student travel award and a second-place poster award at the 2017 FLEX Conference, the nation’s leading forum for flexible, printed, and hybrid electronics technology. The conference hosted over 26 technical sessions and featured international presenters who share the common goal of creating faster, smarter, and more economical electronic devices for everyday use.

Printed and Flexible Electronics – The Future of Electronic Devices

Twinkle’s research focuses on understanding the physics behind power dissipation in aerosol jet printed graphene interconnects. Power dissipation relates current flow to voltage in electronic devices, which can lead to severe internal temperature increases. Power dissipation is a limiting factor in current silicon based computer processors. This is why laptops can heat up significantly, requiring innovative cooling technologies to prevent serious burns. New materials such as graphene have shown potential to improve the efficiency of electronic devices by reducing the temperature rise associated with power dissipation. “To our knowledge, Twinkle’s research represents the first study of power dissipation in printed graphene interconnects,” said Dr. Dave Estrada, Twinkle’s graduate advisor and co-director of the Boise State Advanced Nanomaterials and Manufacturing Laboratory. “Understanding the limiting factors in power dissipation of printed graphene may help expedite the adoption of this material in flexible and printed electronics applications, particularly if it can be printed in a roll-to-roll fashion.”

Collaborative Research Leads to New Innovations

Twinkle continues to conduct her award-winning research in collaboration with the PrintTronics Research Group at Air Force Research Laboratories led by Dr. Emily Heckman, NASA Scientist Dr. Jessica Koehne of the Center for Nanotechnology at NASA Ames Research Center, and Assistant Professor Feng Xiong’s group in the Electrical and Computer Engineering Department at the University of Pittsburgh. The team’s diverse expertise allows a comprehensive approach to research that encompasses materials synthesis and characterization, device fabrication and characterization, and multiphysics modeling. This method of collaborative research has led to new insights that demonstrate the effects of materials structure, properties, and processing on the performance of printed graphene devices. Printed graphene devices have dozens of potential uses such as touch screens in consumer electronics, wearable and stretchable biosensors for monitoring hydration and stress, and environmental monitoring systems for managing the condition of temperature sensitive inventory such as agricultural products and pharmaceuticals.

John-Paul Stroud – Bachelor of Science Alum 2017

JP Stroud 2017 Alum

John-Paul Stroud is originally from Portland, Oregon but moved to Nampa, Idaho in 2004. He has been living in the Treasure Valley ever since. JP attended Renaissance High School in Meridian on the advice of a former teacher. He was hoping to take some interesting and compelling physics courses. Soon after enrolling, John-Paul realized that engineering and biology were the subjects that were most fascinating to him.

JP’s father, who has an interest in materials science, recognized JP’s potential in the engineering field. He began taking JP to research seminars to help develop further interest. With his father’s encouragement and by attending these seminars, JP learned more about materials science and engineering. He had found his field of interest. JP applied for admission to Boise State and is now enrolled in the materials science and engineering program. JP was happy to remain in Boise, a city he fully enjoys. Additionally, he was certain that the Micron School of Materials Science and Engineering (MSMSE) would offer excellent career advancement opportunities.

One of the highlights of the materials science and engineering program at Boise State is the opportunity for undergraduates to become immersed in the materials science world. Faculty make a point of working closely with students. Undergrads have a unique opportunity to work in a lab with a research group. These important experiences facilitate students’ advancement into the materials science industry.

Hands-On Research Opportunities Lead to Success

John-Paul had the fabulous opportunity to work in the Advanced Materials Laboratory while completing his Bachelor of Science. He participated in a variety of research projects, which allowed him to gain significant experience on topics ranging from corrosion to identifying unknown compounds created thousands of years ago.

One of JP’s research projects focused on corrosion and the development of corrosion-resistant sensors for navy and air force aircraft. He also worked on the synthesis of nitrites and nuclear fuel for the advanced fuel cycle initiative. This initiative is supported by the Department of Energy and allows researchers to focus on expanding clean, economical, and sustainable nuclear energy. He performed characterization work on zirconium alloys, which are used in nuclear reactors. They act as a barrier between nuclear fuel and coolant, keeping the entire system safe and secure. JP’s research focused on reducing oxidation in these alloys in order to maximize reactor performance. He hopes his research increases the tolerance for failure of these materials in case of nuclear accidents. In a separate project, JP conducted research to identify the materials used to create an unknown purple pigment found on an ancient mummy portrait.

Internships Make a Difference!

To further develop his expertise in materials science, John-Paul interned at the Idaho National Laboratory. He focused on the preparation of irradiated materials with the goal of improving their quality and safety.

JP helped develop a sample preparation method for a process called Electron Backscatter Diffraction (EBSD.) EBSD uses electron beams to detect texture, grain size, orientation, defects, and other information about crystallized structures in relation to irradiated fuel cladding in nuclear reactors. When a sample is irradiated, the entire process becomes hazardous and creates more waste that must be disposed of responsibly. A possible alternative is to use argon ions to polish the sample’s surface. This method may promote cleaner results from experiments. JP’s goal during this internship was to optimize the argon polishing process for nuclear reactor cladding samples. This process could mean safer conditions within reactors and may even extend the life of current nuclear reactors.

John-Paul continued his internship journey at Tescan, an electron microscope manufacturer, over the Summer 2017. This internship was a great opportunity to conduct research using state-of-the-art scanning electron microscopes (SEMs) and transmission electron microscopes (TEMs) at the Tescan Applications Lab in the Czech Republic.

What is JP Up to Now?

JP graduated from Boise State with a Bachelor of Science in Materials Science and Engineering in Spring 2017. His goal is to continue developing his expertise with an advanced degree. He was accepted to UC Davis in Fall 2017 to pursue his Ph.D. in Materials Science and Engineering. Congratulations, JP!

Eric Jankowski: National Science Foundation CAREER Award

MSMSE Undergrad Materials Lab, Eric Jankowski's Lab

Can you imagine printing a sheet of plastic that covers its own cost by converting sunlight into electricity within a few days? It’s entirely possible if printing technologies can fabricate high-efficiency organic photovoltaics (OPVs). Dr. Jankowski, assistant professor in the Micron School of Materials Science and Engineering leads the Computational Materials Engineering Laboratory (CMELab) at Boise State. The group researches new materials that create sustainable energy sources. Particularly, they research methods for arranging molecules to give carbon-based advanced materials desired properties. Dr. Jankowski received a prestigious National Science Foundation (NSF) CAREER grant for his research into methods that create greener environments.

An NSF CAREER Grant Supports Green Research

The Faculty Early Career Development (CAREER) Program offers the National Science Foundation’s most prestigious awards in support of faculty members who integrate effective research and teaching. Dr. Jankowski’s CAREER award is supporting his research on transforming methods by which organic photovoltaic solar cells are made. The building-block materials used to develop OPVs are abundant and could enhance production of inexpensive solar panels. OPVs can be applied to curved or flexible surfaces that are hard to accommodate with silicon-based solar technologies. This would enable easier solar panel integration into fabrics or even vehicles. Ultimately, OPVs could provide an economical electricity alternative at a lower cost than current solar technologies.

“I’m enormously grateful for NSF’s support through the CAREER award and humbled to be included among its recipients,” Dr. Jankowski said. “This award will provide sustained graduate student support so we can take our preliminary plastic solar material studies to the next level. I’m so excited for the science this is going to make possible.”

Discovering Pathways to Efficient Alternative Power Sources

Dr. Jankowski’s research will focus on improving the simulation techniques for predicting OPV nano-structures. Improving simulation techniques will allow researchers to uncover the nano-structures of ingredient mixtures needed to create OPVs. Dr. Jankowski and his team can then learn more about the fabrication process and discover pathways to increasingly efficient power sources. He and his students plan to collaborate with the National Renewable Energy Laboratory to make and test the plastic solar cells predicted by their research. According to Jankowski,”No other single advance will as broadly improve the health, security, and opportunity for global citizens as these inexpensive, accessible power sources. These power sources will fuel alternative energy development while mitigating climate change.” Students involved in this project will use computational materials science to solve challenges related to low-cost energy alternatives, giving them a leading edge in obtaining high-tech jobs.
