shows both numerically and phonon spectrometrically why Nanobubble is thermally more stable, mechanically stiffer and stay longer.

Results are consistent with observations from nanodroplets, molecular clusters, skins of bulk water and ice - molecular coordination play the key role for this kind of matter.

Supersolidity arises from water molecular under coordination that    Shortens the H-O bond and lengthens the O:H nonbond associated with strong polarization.  The supersolidity disperses the quasisolid phase boundaries, raising the melting temperature and depresses freezing point. The supersolid phase is more viscoelastic, stiffer, ~0.75 mass density with longer H-O phonon lifetime or slower molecular dynamics. The supersolidity is also responsible for high surface stress and hydrophobicity of water skin and frictionless of ice, ...
