Abstract: In-situ cryo-electron microscopy in thin amorphous ice films and ice-dynamics simulations reveal polymorph-dependent growth kinetics of nanoscale ice crystals. Hetero-crystalline ice exhibits anisotropic growth: fast-growing facets are associated with low-density interfaces, driving tetrahedral ordering of… read more here.
