In this work, the possibility of using reactions electrogenerated titrants with phenolic compounds was studied and a method for their coulometric determination in medicaments by galvanostatic coulometry developed. The research objects were: rutin, salicylic acid drugs containing such as «Ascorutin», «Salicylic Paste» Ointment» Russian manufacture. Electrogenerated halogens (Cl2, Br2 I2) hexacya...

Electrochemical double layer supercapacitor cells were fabricated and tested using composite electrodes of activated carbon with carbon black and poly(3,4-ethylenedioxythiophene) (PEDOT), and an organic electrolyte 1M TEABF4/PC solution. The effect of PEDOT on the performance of the EDLC cells was explored and the cells were characterised by electrochemical impedance spectroscopy (EIS), cyclic ...

Prussian blue (PB) mesocrystals with Na as the alkaline metal were synthesized and used as cathode materials in Na-ion batteries. The mesocrystalline structure endowed PB with very different phase change behavior and electrochemical performance in contrast to PB single-crystals in cyclic voltammograms and galvanostatic discharge/charge voltage profiles of PB/Na half-cells.

The synthesis of atomic metal (gold and nickel) clusters by pulsed galvanostatic electrodeposition on nanoporous alumina is presented. The method allows the production of clusters with an average diameter of 0.7 nm for gold and 1.1 nm for nickel, while the size can be controlled through the current density applied. This strategy represents a simple and efficient method for the construction of h...

The existing lithium ion battery model in Multiphysics (MP) software (COMSOL Inc., Palo Alto, CA) is extended to include the thermal effects. The thermal behavior of a lithium ion battery is studied during the galvanostatic discharge process with and without a pulse. ccepted 8 March 2011 vailable online 15 March 2011 eywords: ithium ion battery hermal model © 2011 Elsevier B.V.

A mathematical model is presented for the galvanostatic deposition of Ni(OH)2 films in stagnant Ni(NO,), solutions. The objective is to quantify the anomalous deposition behavior reported previously in which the utilization of the electrochemically generated OW species decreased drastically as the concentration of Ni(N03)2 increased beyond 0.1 M. For example, as the Ni(NO,)2 concentration incre...
