The reaction between Ti 4+ (a Lewis acid) and InSe (a Lewis base) is demonstrated as an example here, and the reaction mechanism is illustrated in Fig. 1b.

Biological systems have evolved to activate substrates using acids and bases simultaneously within an active site. Proteases achieve astounding efficiency in the hydrolysis of robust amide bonds ...

Scientists in China have used a fluorine-containing Lewis acid treatment to develop a perovskite cell that is said to retain between 63% and 80% of its initial efficiency after 14 days under 75% ...
