Phenothiazine is a p-type cathode that follows the anion pairing mechanism, where electrode undergoes extensive expansion and contraction during cycling, which deleteriously affects battery performance.

in this work, the results concerning to the mean activity coefficient measurements for nacl in the (glycerol + water) system using the potentiometric method are reported. the potentiometric measurements were performed on the galvanic cells without liquid junction of the type: ag|agcl|nacl (m), glycerol (wt%), h2o (1 - wt)%|na-ise, in various mixed solvent systems containing 0, 5, 10, 20 and 30 ...

the reduction process for some quinones has been studid by cyclic voltammeby, rotating disk electrode voltammetry and chronopotentiometry in chloroform at platinum, gold and glassy carbon electrodes using tetrabutylmonium perchlorate (tb ap) as supporting eiectrolyte. the results obtained from this study reveal that the reduction of the quinones is two one-electron processes, the first reductio...

Sol-gel and polymeric membrane electrodes, based on thiacalix[4]arene as a neutral carrier, weresuccessfully developed for the detection of VO2+ in aqueous solutions. The sol-gel and PVCmembrane electrodes exhibited linear response with Nernstian slopes of 29.3 and 28.4 mV perdecade, respectively, within the vanadyl ion concentration ranges from 1.0 × 10-6 to 1.0 × 10-1mol dm-3 and from 1.0 × 1...

The electrochemical preparation of poly-N-methylpyrrole (PMPy) coated platinum electrode in chloroform in the presence of tetrabutylammonium Perchlorate, hexafluorophosphate, hydrogensulphate, Periodate and Iodide as supporting electrolytes was performed. The influence of electrosynthesis method, dopant anion type and operation temperature on electrochemical behavior of polymer were demonst...

fabrication of a cysteamine (ca) self-assembled monolayer (sam) modified gold electrode insitufunctionalized with l-lysine (lys) is presented and described. the fabricated electrode was used forhighly selective and sensitive accumulation and the determination of copper ions (cu2+) in a nanomolarconcentration. techniques like cyclic voltammetry (cv) and electrochemical impedance spectroscopy (ei...

A general approach for enhancing the selectivity of anion-responsive liquid-membrane electrodes is described. The method is based on use of the receptor channel of a flowthrough dialyzer unit as the injection loop in a flow-injection system. An appropriate membrane in the dialyzer prevents ionic interferents from reaching an inselective electrode in the final flow stream The concept is demonstr...
