Mesoporous Mn1.5Co1.5O₄ (MCO) spinel films were prepared directly on a conductive nickel (Ni) foam substrate via electrodeposition and an annealing treatment as supercapacitor electrodes. The electrodeposition time markedly influenced the surface morphological, textural, and supercapacitive properties of MCO/Ni electrodes. The (MCO/Ni)-15 min electrode (electrodeposition time: 15 min) exhibited...

this study investigates the vertical replacement of salts, variability of electrical conductivity (ec) and soil acidity (ph) due to direct electrical current. a plexiglas cylinder 100 cm in depth with a 14 cm radius was used as a soil container and filled with uniform moist soil to 90 cm. during the experiments, the bottom 10 cm of soil in the cylinder was kept saturated. a steel bar was used a...

Herein, a stepwise electrodeposition technique was used to synthesize the Pd based nanoparticles on indium-tin oxide (ITO) electrodes. First of all, Pd nanoparticles were electrodeposited on ITO via one step electrodeposition technique. Furthermore, Au was electrodeposited on Pd. Finally, Co was electrodeposited on Au and Pd electrodeposited ITO electrode via stepwise electrodeposition techniqu...

Silicon (Si) is considered the most promising anode material for next-generation high-energy lithium-ion batteries. To enable use of pure Si anodes, patterning essential to reduce electrode degradation caused by volume changes during cycling. The authors herein report a facile and scalable Cu electrodeposition (Cu-ECD) process tailor topography current collectors directed formation columnar ano...

In this paper we report an in situ electrochemical Sum-/Difference Frequency Generation (SFG/DFG) spectroscopy investigation of the adsorption of nitrile and CN from the ionic liquid 1-butyl-1-methyl-pyrrolidinium bis(trifluoromethylsulfonyl) amide ([BMP][TFSA]) containing 4-{2-[1-(2-cyanoethyl)-1,2,3,4-tetrahydroquinolin-6-yl]diazenyl}benzonitrile (CTDB) at Au electrodes in the absence and in ...

Cu-In-Ga electrodeposition on Mo substrate is carried out in acidic aqueous media. Subsequent selenization leads to Cu(In,Ga)Se2 absorber for thin film solar cells. First, conditions to achieve onestep Cu-In-Ga electrodeposition are analysed. Then, Cu-In and CuGa systems are studied. Cu-In electrodeposition is realized under diffusion-control conditions. For Cu-Ga system, first Cu(II) diffusion...

The motivation of using metal oxides is mainly due to its charge storage capabilities, and electrocatalytic, electrochromic and photoelectrochemical properties. But comparing with bulk, nanostructured materials present several advantages related with the spatial confinement, large fraction of surface atoms, high surface energy, strong surface adsorp‐ tion and increased surface to volume ratio, ...

Electrodeposition of copper from acid sulfate solutions at overpotentials on the plateau of the limiting diffusion current density and at higher overpotentials was examined. The average current efficiencies for hydrogen evolution reaction are determined by a measurement of the quantity of evolved hydrogen and the overall electrodeposition current as a function of electrodeposition time, while m...

According to circumstance of kerman sarcheshmeh cooper complex that its anode slime is mainly consisted of Cu, Ag, Au, Pb and Se. In this work, recovery of silver from anode slime and subsequent synthesis of silver nanoparticles from leaching solution was made. Silver was separated from anode slime by using of HNO3 and HCl. X-Ray fluorescence spectroscopy (XRF) was used to characterize anode sl...
