have performed theoretical studies of catalyzed reaction pathways for hydrogen uptake and release in ammonia boranes, hydrazine, and ammonia alane derivatives, within the framework of Density Functional Theory (DFT) [14,15]; the resultant insights are crucial in establishing key mechanisms so as to ...
Hydroxocobalamin Monohydrochloride (CAS 59461-30-2, C62H89ClCoN13O15P), is a white crystalline powder, widely used in pharmaceutical industry, with excellent stability and high bioavailability, playing a crucial role in the treatment of vitamin B12 deficiency and cyanide poisoning....
Nucleophilic substitution of the 5-Cl moiety of the latter compound with hydrazine hydrate and subsequent treatment with carbon disulfide in boiling pyridine gave, quantitatively, the corresponding [1,2,3]triazolo[4,5-d][1,2,4]triazolo[4,3-a]pyrimidine derivatives. Density functional theory (DFT...
PURPOSE: A producing method of a high-density alumina carrier for a hydrazine monopropellant thruster is provided to improve the density of the alumina carrier, and to reduce the specific surface area and the pore volume of the alumina carrier. CONSTITUTION: A producing method of a high-density...
Fine, low bulk density aluminium hydroxide powdered gel was prepared by the mild base hydrolysis of an aqueous solution of aluminium sulfate with hydrazine hydrate. Parameters such as method of addition of reactant, initial concentration of Al3+, mole ratio, final pH and hydrolysis temperature ...
