Graphene sheets are used for the first time to fabricate a new type of solid-contact ion-selective electrode (SC-ISE) as the intermediate layer between an ionophore-doped solvent polymeric membrane and a glassy carbon electrode. The new transducing layer was characterized by transmission electron microscopy, scanning electron microscopy, cyclic voltammetry and electrochemical impedance spectros...

This paper reports an experimental study on the synthesis and electrochemical properties of InVO4 nanotube arrays fabricated by capillary-enforced sol-filling in templates in combination with solvent-evaporation induced deposition. InVO4 sol was synthesized using the sol–gel route from vanadium oxoisopropoxide and indium nitrate with ethanol as the solvent. Nanotube arrays of InVO4 were prepare...

Frequency and Temporal Identification of a Li-Polymer Battery Model Using Fractional Impedance — The modelling of high power Lithium batteries may work as a powerful tool in the sizing of batteries pack in hybrid vehicles. Moreover, this tool can be used to evaluate accurately the battery characteristics at each level of its lifetime. Until now, the model structure differs according to its end-...

Flow-through stripping chronopotentiometry with a gold wire electrode was used for the determination of total arsenic and cadmium in cadmium sulphate solutions for cadmium production. The analysis is based on the online separation of arsenic as arsenate anion from cadmium cations by means of a cation exchanger. On measuring arsenate in the effluent, the trapped cadmium is eluted by sodium chlor...

The presence of melanin pigments in organisms is implicated in radioprotection and in some cases, enhanced growth in the presence of high levels of ionizing radiation. An understanding of this phenomenon will be useful in the design of radioprotective materials. However, the protective mechanism of microbial melanin in ionizing radiation fields has not yet been elucidated. Here we demonstrate t...

Electrochemical oxidation has been proposed as a remediation method for chlorinated phenols but is hampered by anode fouling. In this work we explore the mechanism of anode fouling by chlorinated phenols, compare structure vs reactivity for phenols differing in the extent of chlorination, and relate the efficiency of oxidation to the mechanism of oxidation at different electrode types. Linear s...

Amorphous hydrogenated silicon (a-Si:H) is known to be a perspective material for negative electrodes of modern lithium-ion batteries. The electrochemical lithium insertion into thin-film a-Si:H electrodes is studied using chronopotentiometry, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). The electrodes were grown on stainless-steel substrates by glow discharge at t...

Optimizing electrocatalytic activity and recognizing the most reactive sites for oxygen evolution reaction (OER) electrocatalysts are valuable to order of renewable power. In this research article, we explored an innovative in-situ annealing technique constructing iron carbide nanoparticles (Fe3C NPs) encapsulated via nitrogen phosphorous doped bamboo-shape carbon nanotubes (NP-CNTs) OER. Inter...

The electro-deoxidation of metal oxides has been presented as an alternative to the pyro- and electro-metallurgical techniques generally used create metals alloys. However, previous research concentrated on employing chronoamperometric analyse cathodic reactions, ignoring important information reduction processes. In this work, we examine using several DC voltammetric techniques, including cons...
