the muscle-like technology would be of enormous advantages for biomedical applications such as medical implants and human assist devices. ionic polymer metal composites (ipmcs) are one kind of biomimetic actuators. an ionic polymer metal composite composed from an ionomer with high ion exchange capacity that packed between two thin metal layers. in the present study we focused on the preparatio...

One of the major sources of lost capacity in all-vanadium redox flow batteries (VRFBs) is the undesired transport (usually called crossover) of water and vanadium ions through the ion-exchange membrane. In this work, an experimental assessment of the impact of ion-exchange membrane properties on vanadium ion crossover and capacity decay of VRFBs has been performed. Two types of cationic membran...

Abstract The alternative desalination technique of membrane capacitive deionization (MCDI) has emerged in the last 15 years and received a lot research attention since then. By using voltage applied between two electrodes covered with ion-exchange membranes, MCDI attempted to challenge established methods such as reverse osmosis or electrodialysis. In this study, through crosslinking sulfosucci...

We demonstrate the use of a novel pulse (18)O-(16)O isotopic exchange technique for the rapid determination of the oxygen surface exchange rate of oxide ion conductors while simultaneously providing insight into the mechanism of the oxygen exchange reaction, which contributes to the efficient development of devices incorporating these solids, such as solid oxide fuel cells and oxygen transport ...

Abstract Graphene oxide (GO) membranes have been proved to be ion-selective thanks their oxidized functional groups, which are naturally present on its surface. This ion selectivity, together with good mechanical strength, low cost, and simple synthesis, makes GO a great alternative material conventional costly polymers for the production of ion-exchange membranes. work focuses how produce as s...

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...

Membrane capacitive deionization (MCDI) is a promising technique to achieve desalination of low-salinity water resources. The primary requirements for developing and designing materials MCDI applications are large surface area, high wettability water, conductivity, efficient ion-transport pathways. Herein, we synthesized ionic covalent organic nanosheets (iCONs) containing guanidinium units tha...

Membrane capacitive deionization (MCDI) is a promising technique to achieve the desalination. This novel technique can largely improve the desalination efficiency of capacitive deionization (CDI) by introducing ion-exchange membranes into CDI. This paper presents a comparative study on the electrosorptive performances of CDI and MCDI based on single walled carbon nanotubes electrodes in NaCl so...
