The phase formation and solid solid solution system of Lithium Iron (II) Phosphate and Lithium Manganese (II) Phosphate using solid state reaction have been studied. The observed phases were identified by X-ray powder diffraction and Electrochemical measurements. The synthesised phases show X-ray diffraction spectra typical of orthorhombic symmetry, space group Pmnb and are closely related to ...
Corrosion inhibition of mild steel in 1 M HCl and 0.5 M H2SO4 by dapsone were studied by polarization resistance, Tafel polarization, electrochemical impedance spectroscopy (EIS) and weight loss measurement. Results obtained revealed that inhibition occurs through adsorption of the drug on metal surface without modifying the mechanism of corrosion process. Potentiodynamic polarization suggested...
The electrocatalytic oxidation of captopril (CAP) was studied by modified carbon nanotubes paste electrode in the presence of isoproterenol (ISPT) using cyclic voltammetry (CV), chronoamperometry and square wave voltammetry (SWV). Also, the values of catalytic rate constant (k), and electron transfer coefficient (α) for CAP were calculated. The mechanism of CA electrochemical behavior at the mo...
Biuret-modified tetraamidomacrocyclic cobalt complex [CoIII-bTAML]- is shown to catalyze electrochemical water oxidation at basic pH leading to the formation of O2. Electrochemical and spectroscopic studies indicate a high valent cobalt oxo intermediate isoelectronic to CoV(O) as the active oxidant. The kinetic isotope effect of 8.63 indicates an atom proton transfer mechanism.
The corrosion inhibition potential and efficacy of 2-hydropyrimidine-2-thione derivative on mildsteel in 0.5 M sulfuric acid solution was investigated using electrochemical polarization and FTIRspectroscopic techniques. In addition, docking studies were carried out as theoretical investigationof adsorption inhibitor on iron surface. The results of polarization studies indicate...
Here, we report on the first electrochemical study that reveals the kinetics and molecular level mechanism of heterogeneous ion-ionophore recognition at plasticized polymer membrane/water interfaces. The new kinetic data provide greater understanding of this important ion-transfer (IT) process, which determines various dynamic characteristics of the current technologies that enable highly selec...
