A multi-wall carbon nanotubes (MWNTs)-quantum dots (QDs) composite-modified glassy carbon electrode (GCE) was prepared. The complex was characterized by transmission electron microscopy (TEM). The electrochemical behavior of levodopa at MWNTs and QDs-modified GCEs (MWNTs-QDs/GCE) was studied by cyclic voltammetry (CV) and chronocoulometry (CC). It was found that its electrochemical behavior was...

Cyclic Voltammetry (CV) is an electro-chemical characterization technique used in initial material screening for desired properties and to extract information about reactions. In some applications, kinetic of the associated reactions (e.g., rate constants turn over frequencies), CV curve should have a specific shape (for example S-shape). However, often settings obtain such are not known priori...

Abstract Clozapine (CLZ) is one of the most vital medications for managing schizophrenia, and timely measurement CLZ levels has been recognized as an obstacle to wider use CLZ. Herein, first time, nickel-doped graphene nanotubes (Ni@GRNT) were used construct electrochemical sensor by drop coating Ni@GRNT suspension on a glassy carbon electrode. The was synthesized characterized using X?ray diff...

In this study a facile approach to employ Copper nanoparticle (CuNPs) and multi-walled carbon nanotubes (MWCNT) as the nanomaterial for selective detection of asulam have been investigated. This work reports the electrocatalytic oxidation of asulam on glassy carbon electrodes (GCE) modified with multi-walled carbon nanotubes (MWCNT), ionic liquids (IL), chitosan (Chit) and copper nanoparticles ...

Electrochemical properties of transition metal complexes are important parameters that should be considered for the successful application these compounds in catalytic reactions. The proper choice ligands and type its coordination allow construction a catalyst with high performance. reversibility complex oxidation is prerequisite participation redox catalysis, while potential values correlate r...

The adsorbate formed by adsorption of thiophenol on a polycrystalline gold electrode and brought into contact with aqueous solutions of 1 M HClO4 and 0.1 M KClO4 has been studied using cyclic voltammetry and surface-enhanced Raman spectroscopy. A strong adsorption is deduced from observations made using cyclic voltammetry. From the SER spectra, interactions of thiophenol with the gold surface v...

Nanostructured network-like MnO2-NiO composite electrodes were electrodeposited onto stainless steel substrates via different electrodeposition modes, such as chronopotentiometry, chronoamperometry, and cyclic voltammetry, and then subjected to heat treatment at 300°C for metal oxide conversion. X-ray diffraction, field emission scanning electron microscopy, and transmission electron microscopy...
