This work reports on the electrodeposition of rhodium (Rh) nanowires with a controlled surface morphology synthesized using an anodic aluminum oxide (AAO) template. Vertically aligned Rh nanowires with a smooth and coarse morphology were successfully deposited by adjusting the electrode potential and the concentration of precursor ions and by involving a complexing reagent in the electrolyte so...

A novel scheme is presented for the synthesis of graded materials by electrodeposition in porous insulating templates. Lateral control of copper electrodeposition in nanoporous alumina membranes is achieved by application of a lateral potential gradient on a thin Au film evaporated on the membrane, used as the cathode. Formation of metal gradients in the membranes is shown to occur under condit...

Electrodeposition is a very important technology in the fabrication of micro-compo‐ nents for micro-electro-mechanical systems (MEMS) or integrated circuits. Evalua‐ tions of the materials used in these devices as 3D components should be conducted using micro-sized specimens due to the sample size effect on the practical use of the components. Nanocrystalline metals could be deposited using an ...

In this study, the nucleation and growth kinetics behavior of aluminum (Al) were investigated in Choline-chloride (ChCl)-urea deep eutectic solvent (DES) ionic liquids. The studies cyclic voltammetric chronoamperometry demonstrated that electrodeposition process Al was controlled by three-dimensional progressive instantaneous nucleation. And nuclei is a diffusion-controlled process. diffusion c...

Electrodeposition is an important approach that can produce functional compound materials by assembling multiple species at the electrode surface. However, a fundamental understanding of the electrodeposition mechanism has been limited by its complexity and is often gained only through ex situ studies of deposited materials. Here we report on the application of scanning electrochemical microsco...

Two series of electroplating experiments have been carried out onto mild steel substrate at 65 °C in several electroplating baths under different constant applied current densities. The objectives of the first series of experiments are to understand the behavior of electrodeposition of Cu and Sn in the several alkaline cyanide baths and to explore the electroplating conditions which are appropr...

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...

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...

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...
