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

"Freezing" of nanoconfined fluids under an electric field.
TL;DR: It is deduced that the EF can induce more liquid molecules to be aligned to form more ordered layers in the nanogap and be correlated with the liquid polarity and the film thickness.

Shape effects on nanoparticle engulfment for metal matrix nanocomposites
TL;DR: In this paper, the shape and size of Al2O3 nanoparticles are identified for their optimal dispersion in the Al matrix and critical velocity of solidification is calculated numerically for spherical, cylindrical and disk-shaped nanoparticles using an analytical model which incorporates drag force, intermolecular force and inertia effect.

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.
