It has been reported that lithium-rich cathode materials of LIB emit singlet oxygen during charging, which chemically oxidizes electrolyte solutions, and the decomposition products form surface film on material. However, detailed conditions mechanism formation its effect electrochemical reaction at electrode/electrolyte interface have not clarified in detail. In this study, using 0.5LiCoO 2 • 0...

The present work accentuates the aspects of electrochemical analysis determined by cyclic voltammeter (CV), especially enhancement in supercapacitor's specific capacitance and energy density. In this work, nickel oxide (NiO) @ reduced graphene (NiO@rGO) nanocomposite materials used as electrodes were synthesized microwave irradiation method. Performance material was further characterized using ...

The easy and rapid analytical tool, electrochemically polymerized (EP) glycine (GN) layered carbon paste electrode (LCPE), was used for the analysis of levofloxacin (LN) using cyclic voltammogram (CV) differential pulse voltammetry (DPV). surface features activities electrochemical sensors EPGNLCPE bare (BCPE) were analyzed impedance spectroscopy (EIS), field emission scanning electron microsco...

Copper oxide-based gas-diffusion electrodes (CuxO/GDEs) for CO2 electrocatalytic reduction are investigated in presence and absence of liquid electrolyte (liquid- gas-phase operations) terms (i) catalytic reactivity compact-design flow cells (with the located on two sides a Nafion membrane) (ii) situ electrochemical characterization by impedance spectroscopy (EIS), cyclic voltammetry (CV) chron...

[Purpose] Accuracy in coordinating limb movements decreases with aging. The effect of aging on the variability of cyclic movements is not well known. The aim of this study was to examine the effect of aging on seated stepping variability. [Subjects and Methods] Twenty-six healthy young adults and 15 healthy elderly adults were instructed to walk at their preferred speed. Foot contact was monito...

Clay modified carbon paste electrode (CPE-C) its applicability for electroanalysis of N, N’-ethylene-2,2’-bipyridinium (diquat) has been described in the present work. Electrochemical modification was performed by electronic impedance spectroscopy (EIS) and cyclic voltammetry (CV) in the range of -0.6 V to 1.2 V in 0.1 M K2SO4 (pH 3). The voltammetric method behavior of DQ is suggested where an...

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...

Carbon fiber microelectrode (CFME) has been extensively applied in the biosensor and chemical sensor domains. In order to improve the electrochemical activity and sensitivity of the CFME, a new CFME modified with carbon nanotubes (CNTs), denoted as CNTs/CFME, was fabricated and investigated. First, carbon fiber (CF) monofilaments grafted with CNTs (simplified as CNTs/CFs) were fabricated in two...

The synthesis and characterization of copper complexes of the phenanthroline based bridging ligands, 9-methyl-2-(2-[4-[2-(9-methyl-1,10-phenanthrolin-2-yl)ethyl]phenyl]ethyl)-1,10-phenanthroline, 1, and 1,12-bis(9-methyl-1,10-phenanthroline-2-yl)dodecane, 2, are presented. Whereas in the first case a discrete dimeric complex [Cu(2)(1)(2)](BF(4))(2) was formed, in the latter, a coordination poly...

Cyclic voltammetry (CV) of polystyrene nanospheres was carried out after immobilisation onto boron-doped diamond electrodes. Although the polystyrene is insulating, a voltammetric response was obtained. This was attributed to the high surface area of the nanospheres, allowing the redox chemistry of the polystyrene surface to be probed despite the non-conducting nature of the bulk. The polystyre...
