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 ...

Enzymes are a continuing source of inspiration for the design of new chemical reactions that proceed with efficiency, high selectivity and minimal waste. In many biochemical processes, different ...

In a chemical first, an international research team has developed a metal-free reaction that hydrogenates aromatic rings to form cyclohexyl derivatives. The achievement could spark a broader range of ...

A study published in Angewandte Chemie International Edition by researchers from Nagoya Institute of Technology, the University of Limoges, and the Indian Institute of Technology Madras explores the ...

ANCIENT alchemists wanted to transform common metals into gold. Now chemists have achieved a more subtle modern-day equivalent – converting the element boron from an acid to a base. The work could ...

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% and ...

Is it an acid, base, or neutral? Make your own acid-base indicator from red cabbage, then test various household substances. Acids and bases are classes of materials that have different properties.
