Interaction of HCl with Cu(100) and (111) surfaces covered by multilayers of oxide lead to adsorption of chlorine on top of the copper surface with a coverage more than more than the saturation coverage. Interaction of HCl with Au/Cu(100) showed two different behaviour depending on the gold...
In addition, cyclic imines are present in the substructures of various bioactive secondary metabolites; e.g., gymnodimine (antagonist for nicotinic acetylcholine receptors)20,21, koranimine (antibiotic)22, and venoms of fire ants (inhibitors of nitric oxide synthase)23. Synthetic cyclic imine sugars...

CuCl2 is an anhydrous, brown solid copper salt which is soluble in water and gives a brownish aqueous solution when concentrated. When diluted, the solution changes its colour to green and then blue. CuCl2 is formed when copper(II) oxide, CuO, is treated with hydrochloric acid, HCl: CuO +...
CuCl2 is formed when copper(II) oxide, CuO, is treated with hydrochloric acid, HCl: CuO + 2HCI→CuCl2 + H2O. The anhydrous form constitutes yellow to brown monoclinic crystals. It is hygroscopic; forms dihydrate on exposure to moist air; density 3.40 g/cm3; melts around 630°C with ...
copper/copper oxide nanoparticles synthesized with Moringa oleiferaandMusa sps.extracts: in-vitroand porcine study Abstract The study analyzed the aqueous leaf extracts ofMoringa oleiferaandMusa sps. for phytochemical components, including flavonoids, sterols, saponins, tannins, and glycosides. The LC–MS...
(VIII) oxide) for 1 h and 0.1 M PBS (pH 7.0) for 1–2 h. Dehydration was carried out using graded series of ethanol (50%, 70%, 80%, 90%, 95% and 100%) for about 15 to 20 minutes at each step. The samples were filtered and embedded in Spurr’s resin. Ultra-...
摘要: The electrochemical behaviour of pre-oxidized copper surfaces prepared by heating in air at 90 degrees C was studied to evaluate the impact of the air-formed oxide layer at the cop... 查看全部>>关键词:Copper Corrosion Oxidation Cuprous ions Cupric ions ...
