The MWCNTs-COOH Paste Electrode (MCPE) was successfully used to study the electrochemical behavior of temozolomide in 0.2 M H2SO4 solution, phosphate buffer solution (0.1M PBS, pH 7.4) and 0.1M NaOH solution by Cyclic Voltammetry (CV) technique. The results exhibit that MCPE can remarkably enhance sensing and electrocatalytic activity towards the oxidation and reductio...

From nanotechnology point of view where conductivity is crucial, although it essential to determine the electrochemical properties Cu doped ZnO nanostructure thin films produced by spin coating, there are rare studies in literature. Therefore, this study, aim was examine thouroughly which were grown on glass substrates using a facile and cost-effective coating method. The effects dopant morphol...

The electrochemical reduction of 1,8-dihydroxy-9,10-anthracenedione (Q) has been investigated by cyclic voltammetry (CV). Both 9,10-anthroquinone (AQ) and 1,8-methoxy-9,10-anthracenedione (DMeAQ) are reduced in two steps. First, they are reduced to the anion radical. Next, the anion radicals are reduced to the dianion. However, the CV of Q shows more cathodic and anodic peaks, which suggests th...

Electrical impedance spectroscopy (EIS) and cyclic voltammetry (CV) measure properties of the electrode-tissue interface without additional invasive procedures, and can be used to monitor electrode performance over the long term. EIS measures electrical impedance at multiple frequencies, and increases in impedance indicate increased glial scar formation around the device, while cyclic voltamme...

Inositol 2-phosphate (Ins(2)P) has been identified in several cell types. The cellular levels of Ins(2)P appear to be directly correlated with the levels of inositol 1:2-cyclic phosphate (cIns(1:2)P) (Ross, T. S., Wang, F. P., and Majerus, P. W. (1992) J. Biol. Chem. 267, 19919-19923). In this study we have detected an enzyme in extracts from CV-1 cells and rat cerebellum that converts cIns(1:2...

The time responses of two electrochemical methods, amperometry (AMP) and cyclic voltammetry (CV), used in a microchannel to detect the concentration variations of an outer-sphere redox species were compared. Overall, our results show that the temporal resolution of AMP is superior to the one of CV. As no secondary reaction (formation of chemical bounds, adsorption, etc.) can hinder the detectio...

Cyclic voltammetric (CV) and chronoamperometric (CA) behaviors of 1,3,5-triphenylformazan (TPF), 3-(p-nitrophenyl)-1,5-diphenylformazan (PNF) and 3-(m-nitrophenyl)-1,5-diphenylformazan (MNF) were studied in dimethyl sulfoxide medium. TPF was found to give a single sharp cathodic CV peak corresponding to a gain of one-electron per molecule. The diffusion coefficient and the number of electrons t...

a simple method has been employed to synthesize copper and copper oxide nanoparticles from copper (ii) succinate precursor by thermal decomposition method using oleylamine as a capping agent. the particles synthesized with oleylamine and triphenylphosphine were well dispersed nanoparticles obtained from x-ray diffraction (xrd). the synthesized copper nanoparticles were characterized by uv-visib...

Phase transformation cyclic voltammetry (CV) was developed by integrating mixed-control phase transformation theory and charge transfer effect with traditional CV model. This mixed-control phase transformation CV model was validated by good agreement between experimental CV data and simulated values from phase transformation CV for LiFePO4. The lithium ion diffusion coefficient (10-16 m2 s-1) o...
