Molecular modeling has become a useful and widely used tool to predict diffusion coefficients of molecules adsorbed in the pores of zeolites and other nanoporous materials. These simulations also provide detailed, molecular-level information about sorbate structure, dynamics, and diffusion mechanisms. We review recent advances in this field, including prediction of various transport coefficients (Fickian, Onsager, Maxwell – Stefan) for single-component and multicomponent systems from equilibrium and non-equilibrium molecular dynamics (MD) simulations, elucidation of anomalous diffusion effects induced by the confining pore structure, and prediction of slow diffusion processes beyond the reach of MD simulations.

A comparison between numerical and analytical modeling of ECAP

Recent developments in nanostructured products draw considerable attention to ultrafine grained materials. These materials are normally manufactured by different severe plastic deformation (SPD) methods. In the present study, analytical models and finite element method (FEM) are used to calculate strain imposed to a specimen that was deformed by equal channel angular pressing (ECAP). In additio...
