New procedure will reduce the need for rare metals in chemical synthesis

Researchers are working to improve the long-term sustainability of pharmaceutical and other chemical syntheses

02-Dec-2020

Pharmaceuticals, plastics, and many other chemical products have transformed human life. To prepare these products, chemists often use a catalyst--frequently based on rare metals--at various points in their syntheses. Although rare-metal catalysts are incredibly useful, their limited supply means ...

Gold- and bronze-like paints that don't contain metal

Researchers have developed organic-only dyes that can form films resembling gold or bronze, without the need for metals

19-Oct-2020

Lustrous metallic paints are used to enhance the beauty of many products, such as home decorations, cars and artwork. But most of these pigments owe their sheen to flakes of aluminum, copper, zinc or other metals, which have drawbacks. Now, researchers reporting in ACS Omega have developed ...
