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

On the shear dilation of polycrystalline lubricant films in boundary lubricated contacts.
TL;DR: This study provides a renewed picture on the physical property of nanoconfined lubricant films in boundary lubrication by observing interlayer slips within the film and shear-induced order-to-disorder transition of lubricant molecules around grain boundaries.

Friction and Plasticity in Contacts Between Amorphous Solids
Binquan Luan,Mark O. Robbins +1 more
TL;DR: In this article, large-scale molecular dynamics simulations of contact and friction between two amorphous solids with self-affine fractal surfaces are presented, showing that the plastic deformation on solid surfaces plays an important role in the interfacial friction that is much higher than expected for elastically deforming surfaces.

The logarithmic relaxation process and the critical temperature of liquids in nano-confined states.
TL;DR: The results of this study indicate that, under nano-confinements, liquids that display logarithmic β-relaxation phenomenon undergo a unique glass transition process.

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.

Frank Philip Bowden,David Tabor +1 more
TL;DR: Tabor and Bowden as mentioned in this paper reviewed the many advances made in this field during the past 36 years and outlined the achievements of Frank Philip Bowden, and reviewed the behavior of non-metals, especially elastomers; elastohydrodynamic lubrication; and the wear of sliding surfaces.

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.
