Freezing point of supercooled water varies with electric charge
(PhysOrg.com) -- Just as water can be superheated and remain liquid above the boiling point if there is no nucleating surface (such as a surface defect or a speck of dust), it can also become supercooled and remain liquid well below its freezing point of 0°C. Now scientists have found that supercooled water freezes at different temperatures in the presence of a surface with a positive or negative charge.

Discovery: Electric charge can change freezing point of water
Scientists had long suspected that electricity could trigger freezing in supercooled water. But the materials to test this theory didn't exist. Using pyroelectric material, however, researchers ...
