Tiny displacements, giant changes in optical properties hile we usually think of disorder as a bad thing, a team of materials science researchers led by Rohan Mishra, from Washington University in St. Louis, and Jayakanth Ravichandran, from the University of Southern California, have revealed that — when it comes to certain crystals — a little structural disorder might have big impacts on useful optical properties. 06.05.2024
Pregnancy is an engineering challenge − diagnosing and treating preterm birth requires understanding its mechanics Michelle Oyen, director of WashU’s Center for Women’s Health Engineering, co-writes an article about studying, and improving, preterm birth outcomes by understanding the materials and mechanics involved. 06.04.2024
Chakrabarty, collaborators win Simons Foundation International grant for geoengineering Rajan Chakrabarty, Rohan Mishra and Lu Xu will explore stratospheric aerosol injection with a $1.5 million grant from the Simons Foundation International 05.15.2024
The Plastics Problem McKelvey engineers tackle one of the biggest environmental issues of our time. 04.30.2024
Imaging technique shows new details of peptide structures A new imaging technique developed by engineers at Washington University in St. Louis can give scientists a much closer look at fibril assemblies, stacks of peptides like amyloid beta, most notably associated with Alzheimer’s disease. These results stem from a fruitful collaboration between lead author Matthew Lew, associate professor in the Preston M. Green Department of Electrical & Systems Engineering, and Jai Rudra, associate professor of biomedical engineering, in WashU's McKelvey School of Engineering. 04.25.2024
Smart nanoparticles may be able to deliver drugs to heart after heart attack With a four-year $2.1 million grant from the National Institutes of Health (NIH), Jianjun Guan and his team plan to enclose a set of proteins designed to curb inflammation and a peptide to prevent fibrosis inside cleverly disguised drug-delivering smart nanoparticles. These nanoparticles would be delivered intravenously into the blood, which would take them directly to the heart. 04.25.2024
Novel material supercharges innovation in electrostatic energy storage In a study published April 18 in Science, Sang-Hoon Bae, assistant professor of mechanical engineering & materials science in the McKelvey School of Engineering at Washington University in St. Louis and his collaborators, including Rohan Mishra, associate professor of mechanical engineering & materials science, and Chuan Wang, associate professor of electrical & systems engineering, both at WashU, and Frances Ross, the TDK Professor in Materials Science and Engineering at MIT, introduced an approach to control the relaxation time – an internal material property that describes how long it takes for charge to dissipate or decay – of ferroelectric capacitors using 2D materials. 04.18.2024
Flores named ASM Fellow Katharine M. Flores, the Christopher I. Byrnes Professor in the McKelvey School of Engineering at Washington University in St. Louis, has been elected a Fellow of ASM (American Society for Metals) International for her contributions to the field of materials science and engineering. She will be inducted at the International Materials Applications and Technologies Conference and Exhibition (IMAT) conference in October 2023. 12.23.2023
Chakrabarty to study vertical distribution of aerosol properties Rajan Chakrabarty, the Harold D. Jolley Career Development Associate Professor in the McKelvey School of Engineering at Washington University in St. Louis, is one of 13 scientists who recently received funding through the U.S. Department of Energy’s (DOE) Facilities Integrating Collaborations for User Science (FICUS) program. 10.27.2023
