Sodium Metal Batteries The art representing article number 2204402 by Yixian Wang, David Mitlin, and co-workers depicts two turtles on a sodium fueled road trip. Neither or batteries are the fastest most powerful, but like turtles, sodium-based energy storage is steady, reliable highly abundant, being found in oceans land. antifluoride hills chalcogenide intermetallics that enable stable operat...

Owing to almost unmatched volumetric energy density, Li-ion batteries have dominated the portable electronics industry and solid state electrochemical literature for the past 20 years. Not only will that continue, but they ar...

The pathophysiology of hypertension, which affects over 1 billion individuals worldwide, involves the integration of the actions of multiple organ systems, including the kidney. The kidney, which governs sodium excretion via several mechanisms including pressure natriuresis and the actions of renal sodium transporters, is central to long term blood pressure regulation and the salt sensitivity o...

in this study, rice husk and sodium silicate solution were used to produce particleboards. sodium silicate was used as bonding aid by 25, 20, 15, 10, 5 and zero percent (based on rice husk dry weight). to modify the mechanism of bondability, one percent of 4,4’-diphenylmethane diisocyanate (mdi) was added for every five percent less sodium silicate solution. the effect of diisocyanate on bondab...

with a mean precipitation rate, much lower than that of the world, iran is among the countries that face severe water challenges. the present study has dealt with the evaluation of hydrochemistry of faryab spring water in hormozgan province, iran. four different composite water samples have been analyzed to detect major anions, cations, total dissolved solids, electrical conductivity, ph, and s...

Several methods for determining exchangeable sodium in human subjects by using the gammaray emitter Na22 (half-life 2.6 years) in conjunction with measurements of body radioactivity have previously been described (1-3). With these methods, it is possible to make repeated exchangeable sodium determinations over a period of several weeks or months after giving a single tracer dose of the radioiso...

Purpose: To investigate the effects of sodium bicarbonate (NaHCO3) on exhaustive activity and physiological parameters of fatigue in conscripts. Materials and Methods: Thirty conscripts did Wingate test in two groups: sodium bicarbonate group (treatment) and placebo (control) group. In both groups, sodium bicarbonate (0.3 g/kg of body mass) or placebo was ingested 60 minutes before the t...

in this research, kinetics of carbothermic reduction of molybdenite in the presence of different amounts of sodium carbonate has been studied. mixed powders consisting of molybdenite, graphite and sodium carbonate with three mole-ratios of 1:4:2,1:4:3 and 1:4:4 were mechanically activated for 40 hours. the results of x-ray diffraction on activated samples showed that no reaction occurrs in diff...
