This study evaluated aquatic toxicities of chromium and chromium-containing laboratory samples representative of effluents from chromium electroplating industries, and compared the aquatic environmental risks of hexavalent and trivalent chromium electroplating operations. Trivalent chromium electroplating has emerged as an acceptable alternative to(More)
Indium(III) sulfide has recently attracted much attention due to its potential in optical sensors as a photoconducting material and in photovoltaic applications as a wide band gap material. On the other hand, optical absorption properties are key parameters in developing photosensitive photodetectors and efficient solar cells. In this work, we show that(More)
Titanium dioxide (TiO2) has long been considered a model photoanode material for electrolysis of water using solar energy. A number of studies have looked into the synthesis methods to optimize physical as well as chemical properties of titania photoanodes. Electric field assisted anodic oxidation of titanium (Ti) for fabrication of titania photoanodes is a(More)
