Properties of Ice and Liquid Interfaces, and Work Functions (Kay's BES-Surface Kinetics, PNNL Scope #16248)
EMSL Project ID
38200
Abstract
Interfaces, solid or liquid, have a unique chemistry, unlike that of any bulk phase. Ice interfaces also tend to have adherent liquid brine films in nature. This program explores interfacial effects including changes in fluidity, transport, and solvation. The knowledge gained relates to reactions and transport across two-phase systems: microemulsions, electrochemical systems, cell membranes, enzymes and ion channels, and environmental interfaces at normal humidities, such as the surfaces of atmospheric or soil particles. We explore these systems via re-creating liquid-liquid interfaces using molecular beam epitaxy, and use of a molecular soft landing ion sourc, and recently low energy secondary ion mass spectrometery (all located in EMSL1114). We also explore fundamental properties of bulk ice, related to proton transport, amorphous ice properties, unique electrical properties and even the effect of ice in formation of planets. We also explore aspects of extremely uniform workfunction surface.
