Title: Chemical Thermodynamics of Aqueous Atmospheric Aerosols: Modeling and Microfluidic Measurements
Venue: Room 118, Chemical Engg Dept

Atmospheric aerosols, suspensions of tiny particulate in the atmosphere, are known to have a major impact on the energy balance of the Earth that drives climate change. However, large uncertainty in climate modeling arises when attempting to predict the aerosol effect, due to highly chemically and physically complex nature of the aerosol particles. This talk comprises of (1) development of thermodynamic models to predict solute and water content in aqueous aerosols, and (2) development of an experimental approach to measure water loss and phase, using droplet microfluidics. The talk will end with a vision to use kinetics of mass transfer, in addition to chemical thermodynamics and multiphase microfluidics, to further study water content in complex systems that will have applications in atmospheric aerosols, as well as, emulsions in food and pharmaceutical products.

Lucy Nandy is a visiting scholar at the University of Illinois at Urbana-Champaign. She received her PhD from the University of Minnesota, Twin Cities. Her research interests are thermodynamic modeling of complex fluids, microfluidic multiphase flows, and transport phenomena. Prior to her doctoral studies, Lucy was a Technologist/Senior Manager in Tata Steel India, where she worked on heat transfer and mixing models implemented to minimize defects in steel slabs. In addition, she has worked as a research scholar in Technical University of Darmstadt, Germany to numerically study evaporative processes. Lucy received her bachelors from National Institute of Technology (NIT), Rourkela (2006) and her masters from Indian Institute of Technology (IIT), Kharagpur(2009), both in Chemical Engineering.
