Fig. shows the same supersolidity of water bridge induced by electrification. The inset displays the water bridge formed between two containers under a 10 6 eV/µm field. The bridge has a rubber-like elasticity of around 6 MPa, which is stable till 330 K . Insets of Fig. and g illustrate the three-dimensional (±; H3O + )⋅4H2O:6H2O hydration cells for ions and proton solvation and the PDPS refinement of phonon spectral peaks. Ions occupy eccentrically the tetrahedrally-coordinated hollow sites to polarize their nearest and the next nearest neighbors to form the supersolid hydration cells.
