International Women’s Day: Twelve more women from chemistry history

8 March is International Women’s Day. In the past few years, Ci has featured graphics on women in chemistry to mark this occasion; first, this one on women in chemistry history, and last year this one on women in chemistry present. This year, here’s another edition, looking at twelve more underappreciated women from chemistry history.

Today in chemistry history: Germain Hess, Hess’s Law, and enthalpy changes

On this day back in 1802, Germain Hess was born in Switzerland. Hess would go on to do important work in the field of thermochemistry, the part of chemistry concerned with energy changes in chemical reactions. His work led to the eponymous Hess’s law, explained in the graphic above. Hess also analysed the mineral silver […]
