Counter crystal seeding phenomenon reported

By / April 21, 2010

The “seed effect” of nucleation in liquids is well known: When liquids come in contact with solids, the crystalline surface can induce layering of the adjacent atoms in the liquid and may prevent or lower supercooling. Generally, its believed that the last atomic layers of the liquid adopt the crystal structure they come in contact…
