Prof. Yuan Yang, assistant professor of materials science, and Wei Min, professor of chemistry, use Stimulated Raman Scattering microscopy to observe—for the first time—ions moving in liquid electrolyte; findings which could lead to improving battery safety while also increasing next-generation energy storage. Their research was recently published online in Nature Communications.
The Applied Physics and Applied Mathematics Department is proud to announce the appointment of two new faculty members. APAM alumn, Kui Ren, joins us as a Professor of Applied Mathematics, and Hadrien Montanelli is a Chu Assistant Professor of Applied Mathematics.
APAM faculty proposals were selected to receive funding for interdisciplinary and translational research. Nanfang Yu (APAM) and Changxi Zheng (Comp Sci) will use advanced nanofabrication techniques to realize a number of flat optical designs that can have disruptive technological impact. Qiang Du (APAM) and Steve WaiChing Sun (Civil Eng), whose proposal will be funded for a 2nd year, strive to make robust, accurate, and reliable predictions for engineering applications related to porous media, such as hydraulic fracture, geothermal energy extraction, and nuclear waste disposal.
“We’ve reached the point where it’s critical for researchers to develop creative solutions for redesigning insulators. Our molecular strategy represents a new design principle for classic devices, with the potential to support continued miniaturization in the near term,” said Columbia Engineering physicist and co-author Latha Venkataraman, who heads the lab where researcher Haixing Li conducted the project’s experimental work.
