Herein, we report a green electrochemical oxidative approach to convert large quantities of graphite into graphene oxide (GO). The resulted GO flakes have been characterized using various analytical techniques. It was possible to control the degree of oxidation of the produced GO via controlling the electrochemical parameters of the process.

Diolefinic antibacterial laser dye namely 1,4-Bis[2-(4-Pyridyl) Vinyl] Benzene (4PVB)have been investigated electrochemically using cyclic voltammetry, chronoamperometry, convolution and deconvolution voltammetry combined with digital simulation techniques at a platinum electrode in 0.1 mol / L Tetra Butyl Ammonium Perchlorate (TBAP) in  solvent 1,2-dichloroethane.  The diolefinic ...

Vanillin is an interesting corrosion inhibitor because of its safe use and high solubility inwater. The effect of vanillin on the corrosion inhibition of carbon steel in 1.0 Mhydrochloric acid solution has been studied using potentiodynamic polarization,electrochemical impedance spectroscopy (EIS) and electrochemical noise (EN) techniques.The effect of temperature on the rate of corrosion in th...

This paper presents a model-based approach on the analysis of complex multidisciplinary electrochemical processes, with implementation on a reactor for the electrochemical conversion of CO2 to formate/formic acid. The process is regarded as a system of interacting physical and electrochemical mechanisms. A process model is developed by combining individual mathematical sub-models of the mechani...

Sensitivity analysis methods were used in conjunction with a mathematical model for corrosion pit initiation in the vicinity of MnS inclusions in stainless steel to investigate the relationship between physicochemical parameters and the potential and concentration distributions. The finite difference method with central differences was used to calculate sensitivities. The mathematical model of ...

Polypyrrole(PPy) nanowire modified electrodes were developed by template-free electrochemical method based on graphite electrode. The modified electrode was characterized by their amperometric response towards nitrate ions. Before reduction of nitrate ions, electrochemical solid-phase extraction (EC-SPE) of nitrate in/on modified electrodes was conducted. It is found that the unusual nanowired ...

Advances in vacuum-tight in situ liquid cell TEM systems have attracted significant attention because of the ability to directly interpret chemical and electrochemical reactions within their native liquid environments [1]. Conducting quantitative in situ electrochemistry experiments within the S/TEM is feasible using the relatively new platform of in situ electrochemical S/TEM (ec-S/TEM). In th...

Electrochemical behaviors of 1-naphthaleneacetic acid (NAA) at an ionic liquid N-butylpyridinium hexafluorophosphate (BPPF6/CPE) modified carbon paste electrode was investigated by cyclic voltammetry (CV) and further used for NAA sample determination. The experimental results showed that NAA at both the bared and the modified electrode showed an irreversible oxidation process, but at the modifi...

This work presents the modelling of impulsional pH variations in microvolume related to water-based electrolysis and hydrogen peroxide electrochemical oxidation using an Electrochemical Field Effect Transistor (ElecFET) microdevice. This ElecFET device consists of a pH-Chemical FET (pH-ChemFET) with an integrated microelectrode around the dielectric gate area in order to trigger electrochemical...
