Many solid-state devices, especially those requiring anion conduction, often add a supporting electrolyte to enable efficient operation. The prototypical case is that of anion-exchange-membrane water electrolyzers (AEMWEs), where addition an alkali metal solution improves performance. However, the specific mechanism this performance improvement currently unknown. This work investigates function...

the reported work is on the preparation and characterization of polyvinyl alcohol -g- polyacrylic acid (pva-g-paa)/ polybenzimidazole sulfone (pbis) cation exchange membrane used for the electro dialysis of sodium chloride solution. the polymer syrup has been prepared using the grafting method with the help of polyvinyl alcohol and polyacrylic acid in the presence of water solvent. the polymer ...

A novel non-plasticized nano-porous hybrid inorganic-organic polymer inclusion membrane (PIM) was synthesized, characterized, and evaluated as an anion exchange for application in electrogenerative processes to recover Pd2+ ions. Ionic liquids 1-ethyl-3-me­thyl­imidazolium chloride (EMIM-Cl) 1-butyl-3-methylimidazolium (BMIM-Cl) were used the carrier molecules polymeric network of PIM enhance p...

Measurements of cytosolic pH (pHi) 36Cl fluxes and free cytosolic Ca2+ concentration ([Ca2+]i) were performed in the clonal osteosarcoma cell line UMR-106 to characterize the kinetic properties of Cl-/HCO3- (OH-) exchange and its regulation by pHi and [Ca2+]i. Suspending cells in Cl(-)-free medium resulted in rapid cytosolic alkalinization from pHi 7.05 to approximately 7.42. Subsequently, the ...

lead, copper, cobalt, nickel, iron and zinc ions form monocitrate complexes (negative charge) in citrate solution which is absorbed on the citrate form of anion-exchange resins (citrate as counter ion) y exchange of citrate ion with citrate complexes. these are subsequently recovered from the resin by 0.5m ammonium citrate eluent at ph 2.0. under optimized conditions, quantitative recovery was ...

Basolateral membrane chloride permeability of surface cells from rabbit urinary bladder epithelium was studied using the patch-clamp technique. Two types of anion-selective channel were observed. One channel type showed inward rectification and had a conductance of 64 pS at-50 mV when bathed symmetrically by saline solution containing 150 mM chloride; the other resembled high-conductance voltag...

Plasma membrane anion exchangers (AEs) regulate myocardial intracellular pH (pH(i)) by Na(+)-independent Cl(-)/HCO(3)(-) exchange. Angiotensin II (Ang II) activates protein kinase C (PKC) and increases anion exchange activity in the myocardium. Elevated anion exchange activity has been proposed to contribute to the development of cardiac hypertrophy. Our Northern blots showed that adult rat hea...

Abstract The deposition of several alternating anion- and cation-exchange surface layers (layer-by-layer method) is a promising technique for the modification ion-exchange membranes, which makes it possible to essentially increase their selectivity singly charged ions. This paper presents one-dimensional model, based on Nernst–Planck–Poisson equations describes competitive transfer doubly ions ...

In this work, the synthesis of bimetallic Ag and Cu particles on carbon vulcan (AgCu/C) is reported, synthesized by a simple galvanic displacement method using citrate tribasic hydrate as co-reducing agent commercial material based Cu/C template. The materials were characterized several physicochemical techniques, including TGA, ICP-OES, XRD, SEM, BET. catalysts evaluated cathodic for oxygen re...

The cross-linked imidazolium functionalized anion-exchange membranes is in-situ prepared via reaction of chloromethylated poly(styrene-b-isobutylene-b-styrene) with 1,1’-(1,6-hexanediyl)bisimidazole and N-methylimidazole. composite a small amount modified graphene oxide grafted octadecyl propyl phenyl could be further prepared. These exhibit significantly high chemical stability ionic conductiv...
