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

Nanotribology of ethers: effects of molecular asymmetry and fluoroalkyl chains.
TL;DR: The tribological properties of the molecularly thin films of asymmetric ether and fluorinated asymmetrical ether were investigated and suggest that the responsible friction mechanisms are completely different between the two ether films.

Structural transition and solid-like behavior of alkane films confined in nano-spacing
TL;DR: In this paper, the authors carried out accurate molecular simulation of dodecane fluid confined between mica surfaces using molecular models appropriately describing wall-fluid interaction, and they showed that the state condition of the confined fluid is strongly influenced by the wall and fluid interaction.

Freezing of hard spheres in confinement
TL;DR: In this paper, the influence of confinement on the freezing transition of hard spheres is investigated, and it is shown that the coexistence region narrows as a function of the area to volume ratio.

Local chemical potential and pressure tensor in inhomogeneous nanoconfined fluids.
Hossein Eslami,Nargess Mehdipour +1 more
TL;DR: This work has performed molecular dynamics simulations on a large number of nanoconfined Lennard-Jones systems to evaluate the validity of the ansatz that in equilibrium the tangential component of pressure of the confined fluid is equal to the Pressure of the bulk fluid at the same temperature.

Surface energy and the contact of elastic solids
TL;DR: In this paper, the influence of surface energy on the contact between elastic solids is discussed and an analytical model for its effect upon the contact size and the force of adhesion between two lightly loaded spherical solid surfaces is presented.

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.
