Abstract The article presents the possibility of recovering nickel from waste produced as a result wastewater neutralization during electrochemical surface treatment metals. Leaching sludge with concentrated hydrochloric acid enabled metals contained in precipitate to solution efficiency 74.4% (Se) 100% (Zn). content elements was determined using ICP-OES method. next step precipitation obtained...
Laser action has been demonstrated in chalcogenide glass microsphere. A sub millimeter neodymium-doped gallium lanthanum sulphide glass sphere was pumped at 808 nm with a laser diode and single and multimode laser action demonstrated at wavelengths between 1075 and 1086 nm. The gallium lanthanum sulphide family of glass offer higher thermal stability compared to other chalcogenide glasses, and ...
Activation of transient receptor potential ankyrin 1 (TRPA1) and vanilloid 1 (TRPV1) channels on capsaicin-sensitive sensory neurons causes release of inflammatory neuropeptides, including calcitonin gene-related peptide (CGRP). We investigated whether the hydrogen sulphide (H(2)S)-evoked CGRP release from sensory neurons of isolated rat tracheae and H(2)S-induced increases in the microcirculat...
I. The nutritive value of solubilized wool protein prepared by dissolving finely ground wool in sodium sulphide-sodium sulphite solution followed by precipitation with 40 % acetic acid has been tested by incorporating it into protein-free diets containing the amounts of vitamins and minerals required by weanling rats. 2. At the level of 10 % (w/w) of the diet, solubilized wool protein failed to...
Keratinase is a potential industrial enzyme for handling keratinaceous solid wastes and also cleaner dehairing alternative to chemical methods in tanneries. The technologies towards circular economy approach are gaining importance leather manufacturing sector. In this study, new bacterial strain Bacillus sp. KLP1, exhibiting high tolerance sodium chloride sulphide, was isolated. This effectivel...
An intramolecularly P=O-coordinated dicationic diorganotin sulphide is presented. In solution, it shows a monomer-dimer equilibrium.
