Please join us for the Arden L. Bement Jr. Distinguished Lecture virtual event livestreamed here Friday, November 12 at 3:00 p.m. (ET). Congratulations to the 2021 awardee, Michael Manfra, Bill and Dee O’Brian Distinguished Professor of Physics and Astronomy, College of Science; Professor of Electrical and Computer Engineering, Professor of Materials Engineering,…

Researchers at Purdue University (Todd Van Mechelen, Wenbo Sun and Zubin Jacob) have shown that graphene’s viscous fluid (colliding electrons in solids can behave like fluids) support unidirectional electromagnetic waves on the edge. These “edge waves” are linked to a new topological phase of matter and symbolize a phase transition in the material, not unlike the transition from solid to liquid.

WEST LAFAYETTE, Ind. — Three Purdue professors advancing quantum science and work-life and work-life family research policy have been chosen to receive the university's most prestigious research and scholarship awards. Each recognizes recent accomplishments of high significance and impact. 2021 Arden L. Bement Jr. Award: Michael J. Manfra Michael J. Manfra, the Bill and Dee O’Brien Distinguished Professor of Physics and Astronomy in the College of Science, and professor of materials engineering and of electrical and computer engineering in the College of Engineering, will receive the 2021 Arden L. Bement Jr. Award, the most prestigious award given by the university in pure and applied science and engineering. Manfra, a leading condensed matter experimentalist, is being honored for his field-defining work in quantum physics. Manfra and his research team reported in 2020 a landmark experiment that found evidence for fractional statistics of quasiparticles called anyons. This was the first time that anyone showed direct evidence of the fractional statistics of anyons since the quasiparticles were first proposed in the early 1980s, following the discovery of the fractional quantum Hall effect in 1982 (awarded a Nobel prize in 1998).

The U.S. Department of Defense is awarding $2.8 million to a collaborative group of Purdue University professors in order to develop a quantum education program at Purdue. This grant is supported by the National Defense Education Program (NDEP) for Science, Technology, Engineering, and Mathematics (STEM) Education, Outreach, and Workforce Initiative Programs. Professors involved in this grant are Mahdi Hosseini, Assistant Professor of Electrical and Computer Engineering and Courtesy in Physics; Muhsin Menekse, Associate Professor of Engineering Education and Science Education; and Erica Carlson, 150th Anniversary Professor of Physics and Astronomy. Purdue University is the primary recipient of the grant and the work will be done in collaboration with Microsoft Azure Quantum and Guided Particle Systems Inc. Other industry collaborators include IonQ, Entanglement Institute and Quantum Computing Inc.

WEST LAFAYETTE, Ind. — What makes pancreatic cancer so deadly is its covert and quick spread. Now, a “time machine” built by Purdue University engineers has shown a way to reverse the course of cancer before it spreads throughout the pancreas. “These findings open up the possibility of designing a new gene therapy or drug because now we can convert cancerous cells back into their normal state,” said Bumsoo Han, a Purdue professor of mechanical engineering and program leader of the Purdue Center for Cancer Research. Han has a courtesy appointment in biomedical engineering. The time machine that Han’s lab built is a lifelike reproduction of a pancreatic structure called the acinus, which produces and secretes digestive enzymes into the small intestine. Pancreatic cancer tends to develop from chronic inflammation that happens when a mutation has caused these digestive enzymes to digest the pancreas itself.

A Purdue University engineer's patent-pending invention could improve the quality of life for millions of people suffering from diabetic foot ulcers. Rahim Rahimi, an assistant professor in the School of Materials Engineering, has developed a flexible polymer composite microneedle array that can overcome the physicochemical bacterial biofilm present in chronic, nonhealing wounds and deliver both oxygen and bactericidal agents simultaneously. The results have been published in ACS Applied Bio Materials.

As a child, Chi Hwan Lee always had Lego sets on his birthday list. Lee, who loves math and physics, would spend hours building the sets – following the instructions as well as his imagination.That imagination and those Lego pieces became the building blocks of Lee’s Purdue University research, which focuses on converting items like contact lenses and prosthetic hands into smart devices with specially designed electronic stickers to measure vision loss or simulate the sense of feeling. From solar cells to biomedical applications Lee, the Leslie A. Geddes associate professor of biomedical engineering in Purdue’s Weldon School of Biomedical Engineering, says his passion for creating and assembling items continues to grow, thanks to the entrepreneurial and collaborative environment at Purdue. While his initial research involved developing additive manufacturing processes to convert solar cells and sensors to become flexible and even wearable, it was during his job interview at Purdue where faculty members asked if he had ever thought about using his solar cell work in a biomedical setting. That moment was pivotal for Lee, who now has a joint appointment in the School of Mechanical Engineering and a courtesy appointment in the School of Materials Engineering.

A paper from ECE professors Vladimir Shalaev and Alexandra Boltasseva’s research groups has been published in the journal Nature Communications. “High-harmonic generation in metallic titanium nitride” was published Aug. 17, 2021.
