Comparative analysis of copper nanoparticles (CuNPs) obtained by electrodeposition on highly oriented pyrolytic graphite (HOPG) substrates from different supporting electrolytes containing sulphate anions, was performed. Voltammetric results indicated that Cu follows a diffusion-controlled nucleation and crystal growth model for three solutions studied (Na2SO4, H2SO4 Na2SO4+H2SO4). Na2SO4 solut...

In recent years, combinatorial methods have attracted a great deal of attention. Among them, sono-combining techniques have shown a significant potential as an economic technology applicable and environment-friendly technology for wastewater treatment. In this study, Sono Electrochemical SE, Sono Photo Electrochemical SPE and Sono Photo Electro Catalytic SPEC techniques were investigated for de...

This study describes the effects of the substituents on electrochemical behavior and antioxidant activity of the three tetradentate Schiff bases, containing ethane-1,2- diamine, propane-1,3- diamine and butan-1,4- diamine as the amine part and salicylaldehyde, and corresponding Cd(II) complexes. Cyclic voltammograms of these compounds were recorded in dimethylsulfoxide and 0.1 M sodium perchlor...

2-Amino-5,10-dioxo-4-aryl-5,10-dihydro-4H-benzo[g]chromene-3-carbonitrile derivatives are obtained in excellent yields with a simple and efficient procedure.This reaction can occur using electrocatalytic multicomponent chain transformation of aryl aldehydes, 2-hydroxynaphthalene-1,4-dione and malononitrile under neutral and mild conditions. Moreover, electrolysis is done in CH3CN as solvent, Te...

the voltammetric performance of edge-plane pyrolytic graphite (epg) electrode via adsorptive stripping voltammetry was investigated for study of the electrochemical behavior of omeprazole (omz) in aqueous solution. the results revealed that the oxidation of omz is an irreversible ph-dependent process that proceeds with the transfer of one electron and one proton in an adsorption-controlled mech...

Thin films of Sr0.98Zr0.95Y0.05O3−δ (SZY) electrolyte were grown on porous supporting SrTi0.8Fe0.2O3−δ electrodes by the chemical solution deposition method from a low-viscous inorganic salts. The characterized X-ray diffraction and scanning electron microscopy. gas-tightness was evaluated using differential-pressure method. across-plane electrical conductivity 1 mm thick SZY film measured impe...

The construction and characterization of a flow-through polarographic detector for catalyzing the electroreduction of N-nitrosodiethanolamine (NDELA), is discussed. The flow-through cell is equipped with a gold wire electrode (a thin mercury film deposited on a gold substance). The response is evaluated with respect to substance diameter, length, concentration of modifying film, operating poten...

Objectives • Research, develop, assemble, and test a 50 kW net polymer electrolyte membrane (PEM) fuel cell stack system comprised of a PEM fuel cell stack and the supporting gas, thermal, and water management subsystems. The PEM fuel cell stack system will be capable of integration with at least one of the fuel processors currently under development by Hydrogen Burner Technology (HBT) and Arth...
