Fouling of a heterogeneous anion-exchange membrane and single anion-exchange resin particle by ssDNA manifests differently

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...

Behavior of Embedded Cation-Exchange Particles in a DC Electric Field

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...

Effect of graphite felt properties on the long-term durability of negative electrode in vanadium redox flow battery

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&...

3D reconstruction and pore-scale modeling of coated catalytic filters for automotive exhaust gas aftertreatment

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...

Experimental observation of phenomena developing on ion-exchange systems during current-voltage curve measurement

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...
