A new method is proposed for determining the acid number (AN) of biodiesel using coulometric titration with potentiometric detection, basically employing a potentiostat/galvanostat and an electrochemical cell containing a platinum electrode, a silver electrode, and a combination pH electrode. The method involves a sequential application of a constant current between the platinum (cathode) and s...

In the present paper the role of the electrode material in oxygen reduction in DMSO based electrolytes is elucidated using DEMS. We have found, employing platinum, gold, ruthenium rhodium, selenium decorated rhodium and boron doped diamond (BDD) as electrode materials, that the actual mechanism of oxygen reduction largely depends on the electrode material. At platinum, rhodium and selenium deco...

High temperature cyclic voltammetry on microsamples was used for the investigation of the electrochemical stability of BIMEVOX.10 materials. The electrochemical measurements were performed on a three-electrode cell of the type: PtumicrosampleuYSZuPt with the interface PtuYSZ as a pseudo reference electrode. The experiments were performed in nitrogen containing a small quantity of oxygen. The ce...

Despite the significant improvement of polymer electrolyte membrane fuel cell catalyst activities, a cost-effective and stable membrane electrode assembly is still lacking, which greatly inhibits the commercialization of this efficient and environmental friendly technology in stationary and transportation applications. The main reason is that the engineering of different components of an electr...

An accurate description of the electrode-electrolyte interfacial impedance is critical to the development of computational models of neural recording and stimulation that aim to improve understanding of neuro-electric interfaces and to expedite electrode design. This work examines the effect that the electrode-electrolyte interfacial impedance has upon the solutions generated from time-harmonic...

Water electrolysis is one of the most common methods to produce hydrogen gas with high purity, but its application limited due low energy efficiency. It has been proved that an external magnetic field can reduce consumption and increase production efficiency in water electrolysis. In this study, electrodes different magnetism were subjected a perpendicular for use by Gas bubbles evolve from sur...

The cyclic voltammetry of both bulk manganese sulfate (BMS) and nano manganese sulfate (NMS) were studied using 0.1M KCl supporting electrolyte and glassy carbon working electrode. The redox behavior for both bulk (BMS) and MnSO4 (NMS) sulfate was studied voltammetrically in presence and absence of Doxorubicin (DR) using three electrodes system, silver- silver chloride (Ag/AgCl), pla...

The purpose of the study is to assess the selectivity of intradural peripheral nerve activation in primates using a multiple contact cuff electrode. The cuff electrode consisted of four platinum contacts and was implanted around ventral nerve root L5 in the cauda equina. A constant current stimulator delivered single biphasic stimulation pulses. Four monopolar (using a surface indifferent anode...
