Neutron Scattering Studies of Bulk and Confined Liquids: Understanding Glass-Formation and Applications in Environment, Energy and Drug-Delivery.

Suresh M. Chathoth (Oak Ridge National Laboratory)

We have used quasi-elastic neutron scattering (QENS) to understand atomic/molecular relaxation processes in bulk and confined liquids to address the issues related to glass-formation and application for environmental, energy storage and drug-delivery research. Regarding glass-formation, I will present QENS results on metallic glass-forming melts. Next, I will discuss recent results on the dynamics of methane and carbon dioxide in nano-porous carbon aerogel and their implications for CO2 sequestration. Finally, I will discuss the dynamics of confined room-temperature ionic liquids and its relevance in energy storage and QENS studies of a drug-delivery system.
