Irradiation of azobenzene-containing polymer materials with light causes cis–trans isomerization and reorientation of azobenzene moieties and thereby changes in the optical properties of the materials. In this study, the film of poly(ethyl methacry

The diffusion of small molecules through amorphous polymers proceeds by the thermally activated jumps whose rate changes from one region to another due to polymer heterogeneity. Little is known at present about the origin of diffusion heterogeneity.

Although gas sorption in glassy polymers is a well-studied phenomenon, no general microscopical model is developed which is able to describe the gas sorption in a wide temperature range using only characteristics of polymer and gas molecule. In this

Photonic applications of azo compounds often require to know the polarization of molecular absorption bands. In this study, we demonstrate how the kinetics of light-induced anisotropy can be used to determine the mutual orientation of transition dipo

Due to the simple structure, bulk metallic glasses are very convenient model systems for studying the mechanism of atom diffusion in disordered media. In this paper, we analyze literature data on diffusion for a set of atoms in the metallic alloy Zr
