Small molecules in glassy polymers are considered to occupy sites with a distribution of free energies of dissolution. Then their diffusivity depends on concentration and temperature in the same way as it has been derived for hydrogen atoms in metallic glasses. For hydrogen it was shown that the tra

Transport in cellulose gels has been studied with ethylene glycol and crown ether (15-5) as "probes" using an NMR spin-echo technique. The cellulose content was varied in range 20-5570 (w/w). The retardation of diffusion was found to be adequately described by simple first-order expressions in conce
The diffusion of sterically hindered amines with molecular weight 1364, 1393, 2286, and 2758 was studied in polypropylene between 60 and 130Β°C. The diffusion coefficient changes with time and plots log D vs 1/T are given as broken lines for additives with molecular weight 2286 and 2758. IR data show
## Abstract Molecular Dynamic (MD) simulations were carried out to determine the MaxwellβStefan (MβS) diffusivities, Δ~i~, and selfβdiffusivities, __D__~i,self~, of methane (C1), ethane (C2), and propane (C3) for a variety of molecular loadings, __q__~i~, in three classes of zeolite topologies: (1)
