Since their inception, computational homogenization methods based on the fast Fourier
transform (FFT) have grown in popularity, establishing themselves as a powerful tool …

This book covers methods of Mathematical Morphology to model and simulate random sets
and functions (scalar and multivariate). These models concern many physical situations in …

Одной из основных проблем синтеза высокомолекулярных углеводородов из
природного газа за одну стадию является быстрая дезактивация каталитических …

In this work, a 3D pore network model (PNM) is introduced for modeling reaction-diffusion
phenomena, with and without coupled heat transfer, in a spherical porous catalyst particle …

The peak parking method was applied to evaluate the surface diffusivity D s of polystyrenes
dissolved in a THF/heptane mixture and transported through porous silica materials with …

The tortuosity parameter, essential in the prediction of molecular transport properties, is
determined for several materials with multiscale porosities: interparticular/interskeleton …

The tortuosity factor of γ-alumina supports and catalysts used in hydrotreating applications
was evaluated in the liquid phase with three different techniques: pulse field gradient-NMR …

The analysis of 3D images of complex materials, once imaging and reconstruction steps
have been thoroughly done, can provide essential information. This analysis can be largely …

Optimization of supported heterogeneous catalysts requires a careful control of their
synthesis conditions and in particular of the metal impregnation step. This paper presents a …

The microstructure of heterogeneous catalysts often consists of multiscale aggregates of
nanoparticles, some of which are highly anisotropic. Therefore, small-angle X-ray scattering …
