Inspired by the supersolidity of solid helium whose fragments experience elastic, repulsive, and frictionless contacting motion , the supersolid water refers to an exotic, gel-like phase formed when subjected to polarization by applying an electric field or lowering the molecular number (CN) . Charge injection by solvation , electric field induction , deposited on dielectric or charged surfaces , entrapped in hydrophobic cavities, or by forming defects, skins, droplets, or bubbles.
