Kinetics of gas adsorption at solid surfaces
We studied the vibrational relaxation of adatoms at solid surfaces during exoergic processes. The solutions of master equations provide non equilibrium vibrational distribution function of the adlayer. The theory has been employed to describe experimental data on hydrogen recombination at metal surfaces and to explain the Adsorption Stimulated Desorption phenomenon.
Kinetics of Phase transformations
The kinetics of phase formation at solid surfaces is described by means of geometrical stochastic approaches and rate equations. The main contribution is represented by the extension of the KJMA model to transition with correlated nucleation. The theory allows to describe experimental data beyond the nucleation stage. Recently, this method has been employed to study phase formation by electrodeposition.
