The initial stage of isotropic-nematic spinodal demixing kinetics of suspensions of very long and thin, stiff, repulsive rods is analyzed on the basis of the N-particle Smoluchowski equation. Equations of motion for the reduced probability density function of the position and orientation of a rod are expanded up to second order in spatial gradients and leading order in orientational order param...

Ozone decomposition kinetics on alumina: effects of ozone partial pressure, relative humidity and state of film oxidation R. C. Sullivan , T. Thornberry , and J. P. D.

Combustion data of ammonium chlorate and nitrite have been analyzed. The leading reactions of combustion of both NH4ClO3 and NH4NO2 at low pressures have been shown to proceed in the condensed phase, with the burning rate defined by the decomposition kinetics at the surface temperature. The kinetics of NH4ClO3 and NH4NO2 decomposition have been calculated by using a condensed-phase combustion m...

Understanding the gas phase decomposition kinetics of the chemical precursors involved in the nucleation and thin-film growth processes is crucial for controlling the surface kinetics and the growth process. The growth of emerging materials such as InN and related alloys requires deposition methods operating at elevated vapor densities due to the high thermal decomposition pressure of these mat...
