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

The Behavior of Cyclohexane Confined in Slit Carbon Nanopore
TL;DR: It is shown that the system freezes with decreasing the pore width, and the freezing temperature of nanoconfined cyclohexane is higher than the bulk one.

Effect of confinement on the solid-liquid coexistence of Lennard-Jones fluid.
Chandan K. Das,Jayant K. Singh +1 more
TL;DR: The solid-liquid coexistence of a Lennard-Jones fluid confined in slit pores of variable pore size, H, is studied using molecular dynamics simulations and thermodynamic melting temperature is found to oscillate with wall separation, in agreement with the behavior seen for kinetic melting temperature evaluated in an earlier study.

Thin liquid film lubrication under external electrical fields: Roles of liquid intermolecular interactions
TL;DR: In this paper, the effect of the intermolecular interaction in liquid lubricant films on the formation of ordered layers after applying external electric fields (EEFs) has been investigated by measuring the central-film-thicknesses of liquids in concentrated point contacts and then inferring the thin film rheology.

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.
