TLDR
The liquid-to-solid transition of a simple model liquid confined between two surfaces was studied as a function of surface separation and the rigidity of the confined films increased reversibly by at least seven orders of magnitude.Abstract:
The liquid-to-solid transition of a simple model liquid confined between two surfaces was studied as a function of surface separation. From large surface separations (more than 1000 angstroms) down to a separation corresponding to seven molecular layers, the confined films displayed a liquid-like shear viscosity. When the surface separation was further decreased by a single molecular spacing, the films underwent an abrupt, reversible transition to a solid. At the transition, the rigidity of the confined films (quantified in terms of an "effective viscosity") increased reversibly by at least seven orders of magnitude.read more

Nucleation of Frank Dislocation during the Squeeze-Out Process in Boundary Lubrication: A Molecular Dynamics Study
TL;DR: In this paper , the phase transition and solvation force oscillation behavior of a simple argon liquid film confined between two solid surfaces are investigated in a novel scenario in which the n → n − 1 layering transitions are accompanied by the formation, climb, and annihilation of Frank partial dislocations during the squeeze-out process under compression.

Confined Fluid Analyzed with Near-field Acoustic Detection
TL;DR: In this article, a tuning fork-based scanning probe microscope is used to measure the damping and elastic interactions between two solids interfaces (one being the apex of a tapered probe that is attached to one tine of a quartz tuning fork while the other is a flat substrate) under relative lateral oscillatory motion.

Molecular dynamics simulation and thermodynamic model of vapor–solid coexistence of the Lennard–Jones fluid in cylindrical nanopores
TL;DR: In this article, the authors used molecular dynamics simulations to study the coexistence of solids and vapors of Lennard-Jones methane condensed within cylindrical carbon nanopores, and the results of these simulations were compared with the Clausius-Clapeyron equation starting from the triple point in the nanopores.

Substrate colonization by an emulsion drop prior to spreading.
Suraj Borkar,Arun Ramachandran +1 more
TL;DR: In this article, the authors present experimental evidence of a new wetting mechanism, whereby the drop dissolves in the medium, and nucleates on the surface as islands that grow with time.

Slow viscous motion of a sphere parallel to a plane wall—I Motion through a quiescent fluid
TL;DR: Asymptotic solutions of the Stokes equations are derived for both the translational and rotational motions of a sphere parallel to a plane wall bounding a semi-infinite, quiescent, viscous fluid in the limit where the gap width tends to zero as discussed by the authors.

Physics of the Granular State
TL;DR: The generation of analogies between the physics found in a simple sandpile and that found in complicated microscopic systems, such as flux motion in superconductors or spin glasses, has prompted a number of new theories and to a new era of experimentation on granular systems.
