Study on Synthesis and Modification of Conical Ni Structures by One-Step Method [PDF]
Archives of Metallurgy and Materials, 2021 In this work the conical Ni structures were obtained from an electrolyte containing NH4Cl as a crystal modifier. This process is called one-step method and allows to cover large areas with micro- and nanostructures during a single electrodeposition ...

Removal of heavy metals from Water Rinsing of Plating Baths by Electrodialysis
E3S Web of Conferences, 2013 During the chromic plating of parts, the baths become more and more poor in chromic acid and rich in metallic impurities such as Cu2+, Zn2+, Fe3+ and Cr3+ which makes the bath useless.

Chromic Acid Oxidation of Ethyl Alcohol [PDF]
Nature, 1949 IN connexion with a problem of biosynthesis, we had occasion to prepare a sample of ethanol in which some of the α-hydrogen atoms were replaced by deuterium. This was done by heating propionic acid with deuterium sulphate, recovering the labelled propionic acid and treating its silver salt with bromine in carbon tetrachloride; the resulting ethyl ...
