“…The fit (solid line) in Figure 26 gives A = 140 ± 10 (nm) and B = 41 ± 4 (nm). These thickness values agree well with those found by proton channeling [250] and are about twice those reported in an atomic force microscopy (AFM) study [98]. To quantify the adhesion interaction, we integrated the approach curves in Figure 25a to obtain the work of adhesion at different temperatures.…”

“…This water film, termed a "liquid-like layer" (L-LL), is the result of premelting and is expected to possess physical properties between those of water and ice. The presence of the L-LL has been verified by a wide range of physical techniques, including optical spectroscopy [248], scattering [249], proton channeling [250], ellipsometry [251], wire regelation [252], calorimetry [253], and scanning probe microscopy [98,169,[254][255][256]. Several review articles have summarized previous work in this field [94][95][96].…”

This report summarizes the work completed under the Laboratory Directed Research and Development (LDRD) project 10-0973 of the same title. Understanding the molecular origin of the no-slip boundary condition remains vitally important for understanding molecular transport in biological, environmental and energy-related processes, with broad technological implications. Moreover, the viscoelastic properties of fluids in nanoconfinement or near surfaces are not well-understood. We have critically reviewed progress in this area, evaluated key experimental and theoretical methods, and made unique and important discoveries addressing these and related scientific questions. Thematically, the discoveries include insight into the orientation of water molecules on metal surfaces, the premelting of ice, the nucleation of water and alcohol vapors between surface asperities and the lubricity of these molecules when confined inside nanopores, the influence of water nucleation on adhesion to salts and silicates, and the growth and superplasticity of NaCl nanowires.

“…Temperature plays a particularly important role in controlling the rate of gaseous exchange across the solid-vapor interface, as well as the magnitude of the overall uptake. The temperature dependence of the hypothesized liquid-like properties of the ice surface (26)(27)(28)(29)(30)(31)(32), for instance, has been invoked to explain various experimental data and to model environmental effects (1,6,17,33,34). Because the thickness of the disordered surface region of ice increases strongly as the temperature approaches the melting point, one might reasonably expect the equilibrium uptake to increase with temperature, in opposition to classical adsorption behavior.…”

“…The self-diffusion coefficient o f m o l e c u l e s is two orders of magnitude larger than that in bulk ice. Using proton backscattering, Golecki and Jaccard [27] found in 1977 that surface vibrations of the oxygen atoms are roughly 3.3 times the amplitude of their bulk value, and e s t i m a t e d an amorphous layer 10 times thicker than what NMR measurements had estimated. But, unlike NMR, the proton backscattering measurements were made under high vacuum, a condition markedly different from the finite vapor pressures at which surface melting typically occur.…”

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.
