New type of crystal expels liquid when squeezed

Accidental discovery uncovers crystalline solid with very unusual property
A new type of crystalline solid changes phase and reversibly releases one equivalent of solvent when heated or put under pressure. It’s ‘a unique behaviour we haven’t seen in any previous materials,’ says Michael Zdilla of Temple University in the US, part of a team that discovered the property by accident. ‘Accidents are, in my experience, the most exciting thing that can happen in science.’
Zdilla and his colleagues were investigating solid electrolyte materials with conductivities approaching those of ceramics when they came across the unique system, which they call a solvate sponge crystal. Typically, when heating crystals, either the material melts, losing no solvent, then reforms when cooled; or it melts, and then decomposes, and the materials cannot reform on cooling. This crystal is different – rather than melting or de ....
