Numerical Study of Concentration Polarization in Electrodialysis for High-Salinity Solution Concentration in Air-Conditioning Systems [PDF]
MembranesConcentration polarization is a common phenomenon in membrane separation processes and generally impairs mass transfer efficiency. Electrodialysis (ED) is considered a promising technology for concentrating high-salinity solutions used in air ...

Microrobots powered by concentration polarization electrophoresis (CPEP) [PDF]
Nature Communications, 2022 Abstract Second-order electrokinetic flow around colloidal particles caused by concentration polarization electro-osmosis (CPEO) can result in a phoretic motion of asymmetric particle dimers in a homogeneous AC electrical field, which we refer to as concentration polarization electro-phoresis (CPEP).

Evaluation of Concentration Polarization Due to the Effect of Feed Water Temperature Change on Reverse Osmosis Membranes [PDF]
Membranes, 2022 Water is a necessary resource for life development. Its excessive consumption has a negative impact, generating scarcity problems worldwide. Desalination is an alternative to solve these problems; its objective is to reduce the concentration of total ...

Ion Concentration Polarization for Microparticle Mesoporosity Differentiation [PDF]
Langmuir, 2019 Microparticle porosity is normally determined in bulk manner providing an ensemble average that hinders establishing the individual role of each microparticle. On the other hand, single particle characterization implies expensive technology.
