In plants, Na+/H+ exchangers in the plasma membrane are critical for growth in high levels of salt, removing toxic Na+ from the cytoplasm by transport out of the cell. The molecular identity of a plasma membrane Na+/H+ exchanger in Arabidopsis (SOS1) has recently been determined. In this study, immunological analysis provided evidence that SOS1 localizes to the plasma membrane of leaves and roo...

Transmembrane electroneutral transport mechanisms [e.g., Na/H exchange, Cl/HCO3 exchange, (K + Cl) cotransport] have recently been identified in a wide variety of cell types. If these exchanges sum to give a net electroneutral Na/K exchange, they may hyperpolarize the membrane potential beyond the value calculated from the Mullins-Noda equation, provided the cell maintains steady state intracel...

This paper shows the possibility of using a microheterogeneous model to describe properties ion-exchange membranes and calculate characteristics reverse electrodialyzer from data obtained. We studied eight samples heterogeneous cation exchange (two each type membrane). The differed in year issue storage conditions. It is shown that for MK-40 MA-41, samples' can differ significantly. counterions...

in the polymer electrolyte membrane fuel cells (pemfcs), low corrosion resistance and high interfacial contact resistance (icr) are two controversial issues in usage of aisi 316l stainless steel as a metallic bipolar plate. for solving these problems, investigation and development of different coatings and/or surface treatments are inevitable. corrosion behavior and icr of aisi 316l specimens c...

Polymer-electrolyte membranes (PEMs) are a key component in electrochemical energy conversion devices where their main function is to selectively transport ionic species. Reducing PEM thickness an effective strategy for improving performance by minimizing losses. However, how affects the intrinsic properties of membrane remains unexplored. This work aims understand effect on structure-property ...
