We have investigated the formation of a platinum thin film from a simple solution of dihydrogen hexachloroplatinate in a low temperature range of 283 to 295 K by a pulse current technique. Despite the low temperature, the platinum thin film observed with a confocal laser scanning microscope does not comprise particle aggregates but dense layer with a small surface roughness that tends to satura...

This research was to prepare the titanium dioxide nanotube arrays (TiNT arrays) and deposit the Au nanoparticles on its surface using the pulse electrodeposition technique. The Au nanoparticles-TiNT arrays (AuNP-TiNT arrays) were characterized by field emission scanning electron microscopy (FESEM), X-ray diffraction, and cyclic voltammetry. The results showed that the Au nanoparticles were unif...

Short-circuiting via dendrites compromises the reliability of Li-metal batteries. Dendrites ensue from instabilities inherent to electrodeposition that should be amenable to dynamic control. Here, we report that by charging a scaled coin-cell prototype with 1 ms pulses followed by 3 ms rest periods the average dendrite length is shortened ∼2.5 times relative to those grown under continuous char...

This paper describes a facile and effective method to synthesize gold nanoflowers (AuNFs) by a controllable electrodeposition method induced by a L-cysteamine (L-Cys) monolayer self-assembled on the surface of a gold electrode. The AuNFs/L-Cys/Au electrodes were characterized by field emission scanning electron microscopy (FE-SEM), cyclic voltammetry, and AC impedance spectroscopy methods. This...

Ionic liquids are considered as a promising, alternative solvent for the electrochemical synthesis of metals because their high thermal and chemical stability, relatively ionic conductivity, wide window. In particular, window enables electrodeposition without any side reaction electrolytes such hydrogen evolution. The silver is conducted in 1-n-butyl-3-methylimidazolium chloride ([C4mim]Cl) liq...
