“…It is easy to show using Eq. [5] and the known value of the icewater interfacial tension, γ = 33 mN/m (23), that the influence of the capillary curvature is two orders of magnitude smaller, compared with the disjoining pressure values and hence can be neglected. A thermocrystallization flux is caused by the latent heat of ice melting and is directed to the hot side according to the theory of mass transfer in frozen bodies (7).…”

“…The difference between the disjoining pressure of a flat and a curved film, according to (7) is f = − (γ /r ), [5] where γ is the ice-water interfacial tension and r is the interlayer curvature, which is almost equal to the capillary radius, r . It is easy to show using Eq.…”

“…The thickness, h, of the nonfreezing interlayers has previously been measured using calorimetry (1,2), dilatometry (3,4), and magnetic resonance analysis (5,6), and it has been shown that the thickness of the nonfreezing interlayers ranges from 25-30 nm at −0.2…”

“…Nuclear magnetic resonance (NMR) [26] spectroscopy suggested liquid layer fo rma ti on on ice: below the melting point there is a narrow absorption line, not the broad line one would expect from a periodic solid. Molecules at the surface between 20 and 0 °C rotate at a frequency five orders of magnitude greater than those in bulk ice, and about 1/25 as fast as those in liquid water.…”

Superlubricity means non-sticky and frictionless when two bodies are set contacting motion. Although this occurrence has been extensively investigated since 1859 when Faraday firstly proposed a quasiliquid skin on ice, the mechanism behind the superlubricity remains uncertain. This report features a consistent understanding of the superlubricity pertaining to the slipperiness of ice, self-lubrication of dry solids, and aqueous lubricancy from the perspective of skin bond-electron-phonon adaptive relaxation. The presence of nonbonding electron polarization, atomic or molecular undercoordination, and solute ionic electrification of the hydrogen bond as an addition, ensures the superlubricity. Nonbond vibration creates soft phonons of high magnitude and low frequency with extraordinary adaptivity and recoverability of deformation. Molecular undercoordination shortens the covalent bond with local charge densification, which in turn polarizes the nonbonding electrons making them localized dipoles. The locally pinned dipoles provide force opposing contact, mimicking magnetic levitation and hovercraft. O:H−O bond electrification by aqueous ions has the same effect of molecular undercoordination but it is throughout the entire body of the lubricant. Such a Coulomb repulsivity due to the negatively charged skins and elastic adaptivity due to soft nonbonding phonons of one of the contacting objects not only lowers the effective contacting force but also prevents charge from being transited between the counterparts of the contact. Consistency between theory predictions and observations evidences the validity of the proposal of interface elastic Coulomb repulsion that serves as the rule for the superlubricity of ice, wet and dry frictions, which also reconciles the superhydrophobicity, superlubricity, and supersolidity at contacts.

“…At present the hypothesis is accepted on the basis of several experimental evidences using NMR (Kvlividze et al, 1974), ellipsometry (Beaglehole and Nason, 1980), electrical (Jaccard, 1967;Maeno and Nishimura, 1978), and other measurements (Nakaya and Matsumoto, 1954;Jellinek, 1959;Golecki and Jaccard, 1977), and theoretical investigations by Fletcher (1962Fletcher ( , 1968, and Lacmann and Stranski (1972). The consensus view is that the layer is stable above about -20*10*.…”
