Abstract:

High temperature thermophysical behavior of model systems of importance to high temperature phenomena including carbon and silicon nitride are studied. Kinetics of evaporation of refractory materials subjected to laser irradiation are studied. Study of thermodynamic effects of melastic collisions are conducted. Results are compared to JANAF Tables. Kinetics of gas phase ionic reaction mechanisms leading to build up of a long chain unsaturated carbon species are studied. Basic chemical steps involved in formation and decomposition of graphite layers are explored.
