electrochemical oxidation of iodide has been studied in the presence of 2-thioborbituric acid using cyclic voltammetry and controlled-potential coulometry. the results indicate that, the resulting iodine takes part in halogenations reaction with 2-thiobarbituric acid. in addition, the present data are indicative of the suitability of iodide as a quasi mediator for determination of 2-thiobarbitu...
Real-time estimation of battery internal states and physical parameters is of the utmost importance for intelligent battery management systems (BMS). Electrochemical models, derived from the principles of electrochemistry, are arguably more accurate in capturing the physical mechanism of the battery cells than their counterpart data-driven or equivalent circuit models (ECM). Moreover, the elect...
To match the relentless pursuit of three research hot points - efficient solar utilization, green and sustainable remediation of wastewater and advanced oxidation processes, solar-mediated thermo-electrochemical oxidation of surfactant was proposed and developed for green remediation of surfactant wastewater. The solar thermal electrochemical process (STEP), fully driven with solar energy to el...
Thermally evaporated silver nanoparticles on conducting substrates spontaneously evolve in size when immersed in pure water. The process was studied using scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), and optical absorption spectroscopy. The particles are proposed to reform through an electrochemical Ostwald ripening mechanism driven by the size dependence of the w...
The electrochemical behaviour of pentacarbonyl(pyrazine)metal(0) complexes of the group 6 elements was studied by cyclic voltammetry in dichloromethane-(n-Bu)4NBF4 solventelectrolyte couple at –20 C vs. Ag/Ag+ or SCE reference electrode. Constant potential electrolyses of the complexes were carried out at their first oxidation peak potentials and monitored in situ by UV-Vis spectrometry. Electr...
Three types of carbon paste electrodes (CPEs) with different liquid binders were fabricated, and their electrochemical behavior was characterized via a potassium hexacyanoferrate(II) probe. 1-Octyl-3-methylimidazolium hexafluorophosphate ionic liquid (IL) as a hydrophobic conductive pasting binder showed better electrochemical performance compared with the commonly employed binder. The IL-conta...
We have investigated factors which may affect accumulated glutamate levels in synaptic vesicles and glutamate efflux. Agents which dissipate the electrochemical proton gradient resulted in a rapid reduction of steady-state vesicular glutamate levels, which was prevented by N-ethylmaleimide. Glutamate efflux was found to occur even in the presence of an electrochemical proton gradient, but was e...
Glucose electrochemical oxidation toward gluconic and glucaric acids over innovative NiO/Ni 3D foam, a mechanism investigation.
The effect of -Al2O3 particles on the electrochemical codeposition behaviour of Co–Ni alloys from sulfamate electrolyte was investigated by codeposition experiments, zeta potential and electrochemical methods. The results indicate that the presence of Al2O3 particles in Co–Ni sulfamate electrolytes contributes to the preferential codeposition of Co. Moreover, increasing Co2+ concentration also ...
Germanium is an outstanding anode material in terms of electrochemical performance, especially rate capability, but its developments are hindered by its high price because it is rare in the crust of earth, and its huge volume variation during the lithium insertion and extraction. Introducing other cheaper elements into the germanium-based material is an efficient way to dilute the high price, b...
