One-step electrodeposition of crystalline zinc oxide thin films on Molybdenum/glass substrates in a low-cost ionic liquid, Reline composed of urea and choline chloride, is presented. X-ray diffraction spectroscopy shows the thin films have wurtzite structure. Raman microspectroscopy indicates a slight oxygen deficit in the film. Both X-ray energy dispersion and X-ray photonelectron spectroscopy...

Metallization of silicon solar cells using electroplating is of interest recently as a cheaper replacement of silver screen printing. Light assisted electroplating of Nickel-Cobalt (NiCo) alloys were studied on crystalline silicon (Si) solar cells in this paper. The effect of illumination was investigated in conjunction with the light absorption properties of the plating solution, emission spec...

A technique is described for assembly of multiple batches of micro components onto a single substrate. The substrate is prepared with hydrophobic alkanethiol-coated gold binding sites. To perform assembly, a hydrocarbon oil is applied to the substrate and wets exclusively the hydrophobic binding sites in water. Micro components are then added to the water, and assembled on the oil-wetted bindin...

background: despite wide application of chromium in electroplating industry, the pulmonary effects of chronic exposure to this chemical have not been extensively studied and are subject of debate and controversy. this study was, therefore, undertaken to further address this issue.   methods: the study population consisted of a group of 15 workers with a history of past and present occupational ...

background: chromium (cr) is the most important element used to plate other metals and electroplating factories are still consid­ered to be the most important industries which pollute the environment to this metal. this paper describes a study con­ducted to determine the efficiency of reverse-osmosis (ro) as a membrane technique for removal of cr from wastewater sam­ples synthetically prepared ...

Materials synthesis often provides opportunities for innovation. We demonstrate a general low-temperature (260°C) molten salt electrodeposition approach to directly electroplate the important lithium-ion (Li-ion) battery cathode materials LiCoO2, LiMn2O4, and Al-doped LiCoO2. The crystallinities and electrochemical capacities of the electroplated oxides are comparable to those of the powders sy...
