CO desorption has the effect of … widening the reactive pressure window, while CO diffusion has the effect of increasing the reaction rate. In some parameter …

The aim of this paper is to examine thoroughly the dynamics of the diffusion process of mobile particles with repulsive …, we have brought forward the diffusion coefficient behaviour which presents singularities in the critical points that …

Due to recent activity involving diffusion measurements using pulsed gradient spin echo techniques, both experimental … and theoretical, we now have a better understanding of diffusion of fluid molecules in a large class of natural and … artificial porous media. At short times, the restrictions cause deviations from free diffusion that depend only on local …

Diffusion is often used as the primary method of molecular transport in drug delivery schemes. We present a systematic … simulated hydrogels and diffusion is modeled using an exact enumeration scheme. We show the fitting parameters to be largely … iterative test that can be used to ensure that one is in this stable regime. Also, the mechanism of diffusion is shown to be …
