Hydrogen Adsorption on (5,0) and (3,3) Na-decorated BNNTs
The storage capacity of hydrogen on Na-decorated born nitride nanotubes (BNNTs) is investigated by using density functional theory within Quantum Espresso and Gaussian 09. The results obtained predict that a single Na atom tends to occupy above the central region of the hexagonal rings in (5,0) and (3,3) BNNT structures with a binding energy of -2.67 and -4.28 eV/Na-atom respectively. When a si...
متن کاملSodium uptake across basolateral membrane of rat distal colon. Evidence for Na-H exchange and Na-anion cotransport.
This study sought to characterize the mechanism of Na transport across basolateral membrane vesicles of rat distal colon. Both an outward proton gradient and an inward bicarbonate gradient stimulated 22Na uptake. Proton gradient-stimulated 22Na uptake was activated severalfold by the additional presence of an inward bicarbonate gradient, and bicarbonate gradient-stimulated 22Na uptake was signi...
متن کاملRevisiting the Hydrogen Storage Behavior of the Na-O-H System
Solid-state reactions between sodium hydride and sodium hydroxide are unusual among hydride-hydroxide systems since hydrogen can be stored reversibly. In order to understand the relationship between hydrogen uptake/release properties and phase/structure evolution, the dehydrogenation and hydrogenation behavior of the Na-O-H system has been investigated in detail both exand in-situ. Simultaneous...
متن کاملNa(+)-H+ antiport detected through hydrogen ion currents in rat alveolar epithelial cells and human neutrophils
Voltage-activated H(+)-selective currents were studied in cultured adult rat alveolar epithelial cells and in human neutrophils using the whole-cell configuration of the patch-clamp technique. The H+ conductance, gH, although highly selective for protons, was modulated by monovalent cations. In Na+ and to a smaller extent in Li+ solutions, H+ currents were depressed substantially and the voltag...
متن کاملHydrogen peroxide activates mitogen-activated protein kinases and Na+-H+ exchange in neonatal rat cardiac myocytes.
Reperfusion of cardiac tissue after an ischemic episode is associated with metabolic and contractile dysfunction, including reduced tension development and activation of the Na+-H+ exchanger (NHE). Oxygen-derived free radicals are key mediators of reperfusion abnormalities, although the cellular mechanisms involved have not been fully defined. In the present study, the effects of free radicals ...
