zn-co electrodeposits have attracted interest because of their significantly higher corrosion resistance in comparison with pure zinc. in this research the influence of bath temperature and electrolyte’s co 2+ concentration on the morphology and composition of the zn-co coatings, electrodeposited on an aisi1018 steel substrate from a weakly alkaline glycine solutions, has been studied. sem and ...
A single-bath electrodeposition method was developed to integrate multilayer Ag/Co nanowires with a commercial anodic alumina oxide (AAO) template with a pore diameter of 100-200 nm. An electrolyte system containing silver nitride and cobalt sulfide was studied using cyclic voltammetry, and the electrodeposition rate was varied to optimize the electrodeposition conditions. A constant stepwise p...
co-fe films were electrodeposited on cu substrate from electrolytes with different co concentration levels. x-ray diffraction (xrd) was used to investigate the films crystal structures. the results indicate that if the co concentration is less that the fe concentration, the cubic structure appears in the films, while the hexagonal structure dominates when the co co...
Co nanowires were fabricated onto the nanoporous aluminum oxide arrays using ac electrodeposition technique. The influence of frequency and pH on the magnetic properties and crystal structure of symmetric (18-18 V) and non-symmetric (18-12 V) electrodeposited Co nanowires was investigated. A direct relation was seen between saturation magnetization, squareness and coercivity of the samples prep...
ni-co/cu multilayers have been grown by electrodeposition method from a single electrolyte (based on ni(so4).6h2o, co(so4).7h2o, cu(so4) and h3bo3) using galvanostatic control on titanium sublayers. the x-ray diffraction (xrd) patterns confirmed the multilayered structure with the nanometer thicknesses. also, electron diffraction x-ray (edx) analysis confirmed the purity of deposited samples. ...
background: due to the potential public health effects of releases of uranium to the environment, isotopic determination and measurement of this radionuclide in environmental samples is very important. achieving this goal, monitoring programs for this radionuclide seems necessary to be applied in many countries. materials and methods: the uranium was separated from the water samples using anion...
Electrolysis of Co(2+) in phosphate, methylphosphonate, and borate electrolytes effects the electrodeposition of an amorphous highly active water oxidation catalyst as a thin film on an inert anode. Electrodeposition of a catalytically competent species immediately follows oxidation of Co(2+) to Co(3+) in solution. Methylphosphonate and borate electrolytes support catalyst activity comparable t...
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...
Nanowire is a cylindrical nano-structure with nanometer dimensions. In this research, the studied nanowire was made from the magnetic triple Ni-Fe-Co alloy. We utilized ordered porous anodic aluminum oxide as a template for the nanowire deposition. The nanowire arrays were electrodeposited in the cylindrical pores of the oxide layer by AC potential in a simple sulfate bath. Then the relation ...
