Polymer electrolyte based on Nafion-117 membranes in the Li+ form with intercalated 1,3-dioxolane-dimethoxyethane solvent mixtures (DOL-DME) has been obtained. The obtained Nafion-Li+-DOL-DME characterized by DSC analysis, IR- and impedance spectroscopy. uptake of membrane DOL-DME mixture amounts to 1.9. is an ionic conductivity ~10−7 S cm−1 at room temperature. comparative study electrochemica...

LiNi 0.5 Co 0.2 Mn 0.3 O 2 (NCM523) cathode materials can operate at extremely high voltages and have exceptional energy density. However, their use is limited by inherent structure instability during charge/discharge exceptionally oxidizing Ni 4+ the surface. Herein, we developed a citrate-assisted deposition concept to achieve uniform lithium-conductive LiNbO 3 coating layer on NCM523 surface...

the conditional formal potential, e°′of methyldopa has been studied by cyclic voltammetry at the surface of activated glassy carbon electrode (agce) as the working electrode in different ph phosphate buffered solutions. the experimental standard redox potential, e°′, of methyldopa is obtained to be 0.72 mv versus she (standard hydrogen electrode). e°′ values have also been calculated with the a...

The redox behavior cobalt chloride was studied voltammetrically in presence and absence of L- Carrageenan (LK) natural polymer using glassy carbon electrodes in 0.1 M KCl supporting electrode. Scan rates are studied for the redox behaviors for CoCl2 alone or in presence of L- Carrageenan (LK) natural polymer. Stability constants for the interaction of cobalt ions with L - Carageenan (LK) natura...

Hydrogen peroxide emerged as major redox metabolite operative in redox sensing, signaling and redox regulation. Generation, transport and capture of H2O2 in biological settings as well as their biological consequences can now be addressed. The present overview focuses on recent progress on metabolic sources and sinks of H2O2 and on the role of H2O2 in redox signaling under physiological conditi...

kinetics of radical polymerizations of waterborne alkyd/acrylic hybrid resin via batch mini-emulsion technique was studied using redox initiators (tbhp/fe2+/edta/asac  and  tbhp/fe2+/edta/sfs) at relatively low temperatures and thermal initiators (bpo, kps and aibn) at higher temperatures to seek the most suitable initiator system. at the end of all reactions the unreacted monomer content was r...
