Chemical Kinetics and Dynamics at Interfaces: Structure and Reactivity of Ices, Amorphous Solids, and Supercooled Liquid Solutions
EMSL Project ID
24694
Abstract
This proposal is a continuation of research under EMSL User Proposal #21890. The objective of this research is to examine physiochemical phenomena occurring at the surface and within the bulk of ices, amorphous solids, and supercooled liquid solutions. The microscopic details of physisorption, chemisorption, and reactivity of these materials are important to unravel the kinetics and dynamic mechanisms involved in heterogeneous (e.g., gas/liquid) processes. This fundamental research is relevant to solvation and liquid solutions, glasses and deeply supercooled liquids, heterogeneous catalysis, environmental chemistry, and astrochemistry. Our research goal is to provide a quantitative understanding of elementary kinetic processes in these complex systems.
