The control of ion trans-membrane transport through graphene oxide (GO) membranes is achieved by electric and magnetic fields. Electric field can either increase or decrease the ion transport through GO membranes depending on its direction, and magnetic field can enhance the ion penetration monotonically. When electric field is applied across GO membrane, excellent control of ion fluidic flows ...

Dialysis is a membrane based separation process in which the concentration gradient across the membrane is the driving force resulting in a flow of material from one side <span style="font-size: 10pt; ...

Porous membranes with ultrafast ion permeation and high ion selectivity are highly desirable for efficient mineral separation, water purification, and energy conversion, but it is still a huge challenge to efficiently separate monatomic ions of the same valence and similar sizes using synthetic membranes. We report metal organic framework (MOF) membranes, including ZIF-8 and UiO-66 membranes wi...

cyanide ion, is an environmentally significant pollutant in many industrial wastewaters.therefore, a considerable number of methods have been studied for the wastewater treatment containingcyanide. the goal of our work consists in applying a simple and economic process for solving this problem ofpollution. the removal of cyanide ions by using three anion exchange membranes has been studied unde...

Mass transport properties were investigated by means of the chronoamperometry method for a series of sulfonated poly~arylene ether sulfone! ~SPES! membranes and sulfonated polysulfide sulfone ~SPSS! polymers of various ion exchange capacities ~IEC! at a Pt ~microelectrode!/proton exchange membrane ~PEM! interface. The temperature and pressure dependence of oxygen transport parameters show simil...

The steady-state maintenance of highly asymmetric concentrations of the major inorganic cations and anions is a major function of both plasma membranes and the membranes of intracellular organelles. Homeostatic regulation of these ionic gradients is critical for most functions. Due to their charge, the movements of ions across biological membranes necessarily involves facilitation by intrinsic ...
