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

Molecular dynamics simulation and thermodynamic model of triple point of Lennard-Jones fluid in cylindrical nanopores
TL;DR: In this article, the triple points of a Lennard-Jones fluid in cylindrical nanopores were examined using molecular dynamics simulations, and the triple-point temperatures in the cylinders were not inversely proportional to the pore size.

Effect of surface texture on freezing in nanopores: surface-induced versus homogeneous crystallization.
TL;DR: These results shed light on solidification in pores by showing that there is a crossover between surface-induced and homogeneous crystallization upon increasing the surface disorder of the host material.

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.
