in the present study, ptruce/mwnts nanocatalysts synthesized via polyol process technique are applied as anode electro-catalyst in methanol electro-oxidation reaction (mor). to characterize the nanocatalysts, tem, xrd, eds and xps are investigated. cyclic voltammetry and choronoamperometry are used to evaluate the electro-catalytic activity and stability of the catalysts in methanol electro-oxi...

a novel ternary schiff base ligand (hl) of ono type and its copper (ii) complex weresynthesised using 2-aminophenol and o-acetoacetotoluidide. they have been characterised by theusual analytical and spectral methods. the interaction of the complex with calf-thymus (ct)dna has been investigated by uv-vis, viscosity measurement, cyclic voltammetry anddifferential pulse voltammetry studies. the re...

a multi-walled carbon nanotube modified paste electrode (mwcn-pe) was used for determination of promethazine (pmz) in drug formulations and blood plasma by cyclic voltammetry (cv) and differential pulse voltammetry (dpv) methods. results revealed that the mwcn-pe shows an electrocatalytic activity toward the anodic oxidation of pmz by a marked enhancement in the current response in buffered sol...

Voltammetry studies of electrodeposition are growing rapidly. Yet, relations for the analysis reactions in voltammetry remain relatively obscure literature. The existing cyclic and square wave their limitations discussed to increase awareness. A retrospective is performed demonstrate impact model selection improving behavior with voltammetric data. repository models proposed further familiarity...

The electrochemical behaviour of ebastine was studied at hanging mercury drop electrode using cyclic voltammetry and differential pulse voltammetry. The molecule shows a single, well defined reduction peak due to the reduction of carbonyl group. The voltammetric conditions were optimized with respect to maximum peak signals. The linearity between the peak signal and the concentration of ebastin...

A new sensitive and selective electrochemical sensor was developed for determination of glutathione (GSH) at the surface of carbon paste electrode (CPE) modified with multi-wall carbon nanotubes (MWCNTs) as a sensor and pyrogallol red (PGR) as a mediator. The mechanism of GSH electrochemical behavior at the modified electrode surface was investigated by various electrochemical techniques includ...

The small molecules NO and CO are known to mediate many physiological processes related to neurology , immunology, and muscle cell action. Electrochemical detection is often considered one of the most sensitive methods of detection, in our case exceeding nanomolar concentrations. In this study we married the technology of silicon planar with self-assembled monolayer membrane modified electrodes...

The antioxidant capacity of essential oils of Mentha spicata L., Mentha x gentilis L., Mentha crispa L., Mentha piperita L. and Mentha x piperita L. was determined by using differential pulse voltammetry. This assay was based on the reduction in the limiting current value of the oxygen electroreduction, which was used to calculate the antioxidant capacity (K) of these species. The species M. x ...
