The calculation of Gibbs reaction free energy of proton-coupled electron transfer (PCET) processes was simplified by the computational hydrogen electrode (CHE) model proposed by Nørskov et al. 54. In these schemes, the concerted proton and electron transfer was assumed and the corresponding free...
The copper(I) oxide and/or copper preparations may also contain essential trace elements and reducing agents, especially ascorbic acid. The copper(I)-oxide is prepared in a large crystal form, by a reduction process using sugar in an aqueous solution of copper(II) oxide-hydrogen-carbonate-...
(Supplementary Fig.2) shows a main peak located at 9669.2 eV with a shoulder at 9664.0 eV, which is indicative of the dominant presence of the wurtzite zinc oxide phase36. After the activation in hydrogen, a characteristic pre-edge shoulder at 9659 eV appeared in the Zn K-edge ...
In fact, copper is known for its electrical and thermal conductivity as well as its average resistance against corrosion, especially copper carbonate or "green of gray" (INERIS, 2014) by forming a green layer, like the green dome of the railway station in Limoges, France. In water, copper ...
After all the metal salt solution has been added, further sodium carbonate solution is metered in until the pH in the precipitation vessel is 8 and the mixture is stirred at this pH for a further 15 minutes. The total consumption of sodium carbonate solution is 3.7 kg. The suspension formed...

Copper does not react with hydrogen, nitrogen, and carbon, even at high temperatures. The solubility of hydrogen in solid copper is insignificant, and at 400°C it constitutes 0.06 mg per 100 g of copper. Hydrogen and other combustible gases (CO, CH4) react at high temperatures with copper...
As such, the terms “hydrogenation” or “hydrogenating” as used herein are intended to includepartial hydrogenation. When applied to a vegetable oil, the present method of hydrogenationadvantageously yields a hydrogenated or partially hydrogenated vegetable oil with doi...
The common green color of copper on exposure to air is a basic carbonate compound. Copper is insoluble in water but readily dissolves in hot sulfuric and nitric acids. The vapor pressure is negligible at low temperatures, but in an industrial setting, in which very high temperatures are used ...
