Weather and climate influence solid state reactions in previously unrealised ways. So say scientists who have found a mysterious liquid phase at the interface between solids when investigating mechanochemical synthesis.
Mechanochemical reactions are performed by grinding two solid reactants together without a solvent. They are often touted as a green alternative to traditional synthesis, and occur via complex pathways quite different to reactions in solution. Humans have used mechanochemistry since time immemorial: to create fire from the friction between two pieces of wood, in the process of ball milling since the industrial revolution, and to prepare powders for pharmaceuticals and rocket propellants.
