An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

Figure 1: General scheme of the 'acid–base pair' concept and guided synthetic routes for mesoporous minerals. In this work, we predictively extend the mesoporous materials family by introducing a new ...

University of Michigan chemists have developed a Lewis acid-base pair strategy to prepare and stabilize a versatile new reagent capable of adding trifluoromethyl groups to molecules. The method ...

Chemists have long known that catalytic Lewis acidic and Lewis basic sites on metal and metal oxide surfaces help spark a range of reactions that are important in industrial chemical and fuel ...
