โœฆ Synopsis

A model is presented which describes features of the "hot", non-cosine and non-maxwelLian velocity distriiutions of Hz molecules desorbing from Ni surfaces. The model, based on detailed balancing, assumes that incident molecules encounter an activation barrier with holes. The model also correlates with results of kinetic measurements: sticking coefficient =0-l, non-activated adsorption at low temperatures and activated adsorption at high temperatures.

We consider degassing of cylindrical sample containing dissolved hydrogen. The experiment is made by the thermodesorption method. In the corresponding boundary-value problem with nonlinear dynamic boundary conditions physicalechemical processes in the bulk and on the metal surface are taken into acc

A simple model was developed for the interpretation of results stemming from the XPS analysis of polymer surfaces modiรed by polyethyleneimine adsorption followed by surface coupling of polysaccharides. Theoretical surface compositions were evaluated from the calculated XPS intensity arising from a
