The freezing of freely suspended, supercooled water drops by contact nucleation has been studied. Water drops were balanced in an updraft of a large vertical wind tunnel and allowed to supercool to ...

Scientists from the Hong Kong University of Science and Technology (HKUST) have recently discovered a non-classical nucleation process that can greatly facilitate ice formation on foreign surfaces.

Crystals form in storm clouds, metals, drug molecules, and even in diseased tissues. Despite their ubiquity, scientists still don’t fully understand what happens when a liquid solution first starts to ...
