Please join the Chemistry Department for the seminar "Linking Atom Positions to Materials Structure-Chemistry for Advanced Material Design and Development," presented by Baishakhi Mazumder, assistant professor in the Department of Materials Design and Innovation at the University at Buffalo, on Thursday, April 13, from 12:15 to 1:30 p.m. in Science and Mathematics Complex 176. 

Abstract
Improving performance and efficiency in a wide range of applications including consumer appliances, all-electric and hybrid-electric vehicles, and extraction and conversion in cost-effective renewable energy sources can save energy, significantly reducing costs, benefiting both the economy and environment. Key to revolutionizing device components for technologies rely on the material architecture and chemistry that controls the crucial properties and performance. One of the ultimate goals of material design and development is to link the complex behavior that occurs at the materials constituent’s level and the desired properties, and ultimately generate know-how about what really happens at the scale of charge carriers and microstructures within the material systems. To achieve this information, Dr. Mazumder and her team employ an advanced microscopy tool, atom probe tomography that can obtain rich atomistic data on the structure and chemistry of these materials systems. Atom probe tomography (APT) is an advanced characterization tool that offers three-dimensional chemical imaging of material structures at the sub-nanometer scale. This lensless point-projection microscopy technique resolves individual atoms from a nano-dimensional tip with magnifications up to 106 generating structure-chemistry information. This information will be crucial to building connections with the material properties and guide the pathways for material design and development.
