Critical droplet theory explains the glass formability of aqueous solutions

M Warkentin, JP Sethna, RE Thorne - Physical review letters, 2013 - APS
When pure water is cooled at∼ 10 6 K/s, it forms an amorphous solid (glass) instead of the
more familiar crystalline phase. The presence of solutes can reduce this required (or …
