Scientists cage chemical demon

A Cambridge University-led research team has discovered a technique to safely handle and transport white phosphorous.

Light and milling balls for greener chemical processes

Light-driven chemical reactions have usually been conducted with large amounts of solvents that are often toxic. By combining them with mechanical energy in ball mills, Professor Lars Borchardt's team at the Chair of Inorganic ...

A closer look at third-hand smoke and its risks

Using state-of-the-art techniques, researchers have gained a better understanding of the complex mix of hazardous chemicals in third-hand smoke—the residual contamination from cigarette smoking—which can linger long after ...

Toxins in old toys an obstacle for circular economy

Letting children play with hand-me-down plastic toys could constitute a health risk. When researchers at the University of Gothenburg tested a large number of old toys and dress-up items made of plastic, 84% of the items ...
