Abstract Herein, a KFeS 2 whisker was formed in mass production at low temperature, with waste cold-rolling sludge as Fe source, which exhibited good performance the removal of Zn/Ni from real electroplating effluent. At laboratory scale, generated 80 °C by hydrothermal method, and grew radially extension reaction time. This method applied pilot where similar also produced residual brownish sup...

Coal is an abundant resource which can be used to produce low-cost energy; however, its usage causes great environmental damage. Before mineral coal used, it must processed remove tailings. These tailings contain pyrite and accumulate in large dumps, presenting significant liabilities, such as acid mine drainage. Another industry that generates liabilities the chrome-plating industry, mainly be...

This paper focuses on electroplating-based volumetric nanomanufacturing to create highly-structured multilayer metallic materials, with precisely designed characteristic lengths in the hundreds of nanometers but volumes of manufactured material in the macro range. This electroplating-based approach also enables batch fabrication of nanostructures. The fabrication relies on automated and repeate...

Nickel thin films have been electrodeposited without the use of an additional seed layer, on highly doped silicon wafers. These substrates conduct sufficiently well to allow deposition using a peripherical electrical contact on the wafer. Films 2 μm thick have been deposited using a nickel sulfamate bath on both n+and p+-type silicon wafers, where a series of trenches with different widths had ...
