Electrostatic interactions between the charge fixed in ion-exchange membranes and the charge borne by large ions present in the desalted electrolyte can significantly promote fouling of the ion-exchange membranes in the case the two charges are opposite. Here we study the interactions b...

Electrodialysis and electrodeionization are separation processes whose performance depends on the quality and properties of ion-exchange membranes. One of the features that largely aects these properties is heterogeneity of the membranes both on the macroscopic and microscopic level. Macroscopic heter...

In our contribution we study the long-term durability of two different graphite felt materials serving as negative electrode in vanadium redox flow battery. Both electrodes differ in the precursor material and the way of activation which causes significant differences in relevant properties&...

Ion-exchange systems represented, for example, by ion-exchange membranes or ion-exchange resin particles exhibit nonlinear current-voltage curves on which one finds three distinct regions. These regions are referred to as underlimiting, limiting and overlimiting ones. Each of these regions reflects pr...

This paper introduces a newly developed methodology for the pore-scale simulation of flow, diffusion and reaction in the coated catalytic filter. 3D morphology of the porous filter wall including the actual distribution of catalytic material is reconstructed from X-ray tomography (XRT) image...

Corrosion casts (CCs) are used for the visualization and assessment of hollow structures. CCs with filled capillaries enable (with the help of imaging methods) to obtain data for mathematical organ pefusion modelling. As the processing is more difficult in case of organs with greater&...
