The development of inexpensive electrocatalysts that can promote the reduction of CO2 to CO with high selectivity, efficiency, and large current densities is an important step on the path to renewable production of liquid carbon-based fuels. While precious metals such as gold and silver have historically been the most active cathode materials for CO2 reduction, the price of these materials prec...

Li-ion microbatteries are the frontline candidates to fulfill requirements of powering miniature autonomous devices. However, it still remains challenging attain required energy densities > 0.3mWh cm −2 μ m −1 in a planar configuration. To overcome this limitation, 3D architectures LIMBs have been proposed. most deposition techniques poorly compatible with because they limit choice current c...

The leading-edge of a substrate undergoing convective mass deposition is region significant local rate compared to the at downstream Leveque concentration boundary layer. increase in due an intrinsic topological transition leading edge, that usually chemistry or geometry target surface for deposition. We study two cases model electrodeposition: flat and corner/step transitions between inert wal...

The Fe nanowires were prepared by Ac electrodeposition method. The two steps anodized aluminum oxides (alumina) were used as templates for electrodeposition of magnetic nanowires. Sulfuric acid was used to anodize aluminum. The pours diameter and growth rate of alumina were investigated. The FeSO4 electrolyte was used for growth of nanowires. The prepared magnetic nanowires were characterized b...

A Ni–Pt alloy porous layer was formed by electrodepositing Pt using Ni as the substrate sample, followed Al-depositing and Al-dissolving. The electrolyzed an aqueous solution medium, Al-dissolving were treated a molten salt medium. used NaCl–KCl with 3.5 mol% AlF3 added. It found that electrodeposition on surface had finer structure. Furthermore, it clarified lower potential, thicker Ni-Pt laye...

The impact of rare earth oxide (REO) concentration on the deposition process and selective recovery metal being deposited from a molten fluoride salt system was investigated by applying Nd Pr varying REO added to electrolyte. A ternary phase diagram for liquidus temperature NdF3-PrF3-LiF constructed better predict optimal electrolyte constitution. Cyclic voltammetry used record three redox sign...

cofecu nanowires were deposited by pulsed electrodeposition technique into the porous alumina templates by a two-step mild anodization technique, using the single-bath method. the electrodeposition was performed in a constant electrolyte while cu constant was controlled by electrodeposition current. the electrodeposition current was 3.5, 4.25, 5 and 6 ma. the effect of electrodeposition current...
