Smaller is better when it comes to microchips, researchers said, and by using 3D components on a standardized 2D microchip manufacturing platform, developers can use up to 100 times less chip space. A team of engineers has boosted the performance of its previously developed 3D inductor technology by adding as much as three orders of magnitudes more induction to meet the performance demands of modern electronic devices.
Particle chasing—it’s a game that so many physicists play. Sometimes the hunt takes place inside large supercolliders, where spectacular collisions are necessary to find hidden particles and new physics. For physicists studying solids, the game occurs in a much different environment and the sought-after particles don’t come from furious collisions. Instead, particle-like entities, called quasiparticles, emerge from complicated electronic interactions that happen deep within a material.
Researchers have demonstrated a new method for testing microscopic aeronautical materials at ultra-high temperatures. By combining electron microscopy and laser heating, scientists can evaluate these materials much more quickly and inexpensively than with traditional testing.
Mr. Kulkarni, who is part of Paul Braun’s group, was selected in a college-wide competition for outstanding research achievement by a graduate student.
“Ashish has been an incredible asset to my group, and this award is wonderful recognition of his intellectual leadership and hard work as a PhD student,” said Braun.
Nancy Sottos, an engineering professor at the University of Illinois at Urbana-Champaign, has been elected to the National Academy of Engineering. She is one of 87 new members and 18 international members announced by the Academy on Feb. 6.
The NSF’s Early Career Development Program’s CAREER Awards are prestigious, competitive awards given to young faculty who exemplify the role of teacher-scholar through outstanding research, excellent education, and the integration of education and research. The program will provide five years of support for the award.
The project funded by the award is entitled "Dynamic point defect architectonics – uncovering crystal chemical design rules for tailored chemical expansion."
Three Illinois Materials Research Laboratory (MRL) faculty, Paul Braun, Director of MRL and Racheff Professor of Materials Science and Engineering, David Cahill, Willet Professor of Materials Science and Engineering, and Brian DeMarco, Professor of Physics, have received Defense University Research Instrumentation Program (DURIP) awards.
Composites made from self-assembling inorganic materials are valued for their unique strength and thermal, optical and magnetic properties. However, because self-assembly can be difficult to control, the structures formed can be highly disordered, leading to defects during large-scale production. Researchers at the University of Illinois and the University of Michigan have developed a templating technique that instills greater order and gives rise to new 3D structures in a special class of materials, called eutectics, to form new, high-performance materials.
Physicist Vidya Madhavan and colleagues find evidence for propagating Majorana quasiparticles in a topological superconductor.
Lithium-ion batteries are notorious for developing internal electrical shorts that can ignite a battery’s liquid electrolytes, leading to explosions and fires. Engineers at the University of Illinois have developed a solid polymer-based electrolyte that can self-heal after damage – and the material can also be recycled without the use of harsh chemicals or high temperatures.
The new study, which could help manufacturers produce recyclable, self-healing commercial batteries, is published in the Journal of the American Chemical Society.
Researchers in the Department of Materials Science at Illinois have found that by applying stress to metallic glasses, it is possible to disrupt the normal aging process of these alloys. The findings, published in Nature Communications, may contribute to an understanding of how to extend the life of this material.
Cahill is a Willett Professor of Engineering and was the department head of materials science and engineering from 2010-18. He is an expert on the concept of minimum thermal conductivity and transient optical measurement techniques. His research program focuses on developing a microscopic understanding of thermal transport at the nanoscale; the discovery of materials with enhanced thermal function; the interactions between phonons, electrons, photons and spin; and advancing fundamental understanding of interfaces between materials and water.
Hoffmann is a Founder Professor in materials science and engineering and a member of the Materials Research Laboratory. His research focuses on topics related to magnetism, such as spin transport, magnetization dynamics and biomedical applications. His work on spin Hall effects has contributed to the development of spintronics, electronic devices that harness electron spin for faster and more efficient computing. Hoffmann is a Fellow of the American Vacuum Society, the American Physical Society and the Institute of Electrical and Electronics Engineers.
Graduate student Edmund Han, left, professor Elif Ertekin, graduate student Jaehyung Yu, professor Pinshane Y. Huang, front, and professor Arend M. van der Zande have determined how much energy it takes to bend multilayer graphene – a question that has long eluded scientists.

Nadya Mason, Professor of Physics and Director of Illinois MRSEC, has won the 2020 Edward A. Bouchet Award of the American Physical Society (APS). This award recognizes a distinguished underrepresented-minority physicist who has made significant contributions to physics research and the advancement of scientists from underrepresented groups.
The project, High Energy Density Anode Technologies (HEDATs), is focused on the basic science underpinning high-energy anodes, solid electrolytes, dense cathodes and the interfaces in such systems. Creating the next-generation of technologies to enable safe, reliable, and high-performance energy storage is the goal of this foundational research.
MRL, MRSEC, and IQUIST gave an overview of facilities, research, and educational outreach, and the Chancellor got a tour of two of the latest acquisitions, the Cameca Atom Probe and the Themis STEM Lab. Students presented some of their recent work.
Kenis, the Elio E. Tarika Endowed Chair and head of the Department of Chemical and Biomolecular Engineering, was cited for his exceptional contributions to the invention, characterization and development of innovative processes based on microfluidic systems for diverse applications in electrochemical energy conversion, chemical synthesis, and biology.
