S, N co-doped carbon nanotube-encapsulated CoS2@Co

Electrochemical water splitting is favorable strategy to produce high-purity H2. The current mainstream catalysts for water electrolysis are precious metals (Pt, RuO2, IrO2), which possess superior catalytic activity, relatively ...

Modern alchemists are making chemistry greener

Ancient alchemists tried to turn lead and other common metals into gold and platinum. Modern chemists in Paul Chirik's lab at Princeton are transforming reactions that have depended on environmentally unfriendly precious ...

A cost and resource analysis of sodium-ion batteries

Lithium and cobalt are fundamental components of lithium-ion batteries. Analysis by researchers at the Helmholtz Institute Ulm (HIU) of the Karlsruhe Institute of Technology (KIT) shows that the availability of both elements ...

Cobalt boom turns life upside down in DR Congo

In early 2014, according to local folklore, a man digging a septic tank or a well in his garden in Kasulo came across rocks with a distinctive grey-green sheen: cobalt.
