Molecular sieving of tetraalkylammonium cations on cation exchange systems in DC electric field

Ion exchange membranes and ion exchange resin particles are widely used in electro-membrane separation processes such as electrodeionization and electrodialysis. The internal structure of these ion exchange systems implicitly determines their properties, which, in turn, strongly affect the efficiency ...

Triboelectric charging of polyethylene powders: Comparison of same-material and different-material

The understanding of triboelectric charging of industrially important powders can help in avoiding or controlling the particle agglomeration and wall sheeting. We developed a new experimental approach to study both same material particle-particle (P-P) and different-material particle-wall (P-W) charging&#x...

Effect of channel geometry on ion-concentration polarization-based preconcentration and desalination

Polarization of the ion-selective systems results in the formation of ion-depleted and ion-concentrated zones in the electrolyte layers adjacent to the system. One can employ ion-concentration polarization for the removal of chargedlarge molecules and small ions from the flowing liquid. Removal&#...

A complex four-point method for the evaluation of ohmic and faradaic losses within a redox flow battery single-cell

We propose a complex 4-point method for characterization of flow batteries. The distribution of ohmic and faradaic losses within a single-cell is evaluated from electrochemical impedance spectra and load curves of positive and negative half-cells measured with platinum wire pseudo-reference elect...
