Sentences with phrase «nickel catalyst»
A "nickel catalyst" refers to a substance that helps speed up a chemical reaction without getting used up in the process. Nickel is a type of metal that is often used as a catalyst in various industries. It helps make reactions happen faster by providing a surface for other substances to react on, ultimately increasing the efficiency of the reaction. Full definition
Nobuaki Kambe, Professor, and Takanori Iwasaki, Assistant Professor, at the Graduate School of Engineering, Osaka University developed a synthetic method by constructing carbon frameworks of 8 carbons through the formation of a bond of two butadiene molecules by using a cheap nickel catalyst and introducing an alkyl group and a benzene ring to an internal and terminal carbons of 1,6 - octadiene, respectively.
