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

Diminution of the ordering in plastic and liquid crystalline phases by confinement.
TL;DR: Calorimetric and X-ray features that are drastically affected by confinement and orientation in Anopore membranes are reported and are expected to open up a new path to understand the melting phenomenon, especially that which occurs in lower dimensions.

Self-diffusion and structural properties of confined fluids in dynamic coexistence
TL;DR: In this article, self-diffusion and radial distribution functions are studied in a strongly confined Lennard-Jones fluid, where the system exhibits dynamic coexistence, and the selfdiffusion constants are shown to present up to threefold variations from solid to liquid phases at fixed temperature.

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.
