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

Seclusion of molecular layers in a confined simple liquid
TL;DR: In this article, the authors put forward a new concept of layering transitions in nanoconfined films and found equivalence between the splitting of the liquid into thermodynamic sub-states and the formation of secluded molecular layers.

Chapter 11 – DYNAMICS OF CONFINED POLYMERS
TL;DR: In this paper, the dynamics of confined polymers are discussed, where the polymer can be viewed as a single chain, which moves in a restricted space, and the dynamic properties include molecular transport by diffusion, in a hydrodynamic flow or by electrophoresis.

TL;DR: In the solid-liquid phase transition region, where the system exhibits dynamic coexistence, the self-diffusion constants are shown to present up to three-fold variations from solid to liquid phases at fixed temperature.

Size Effect On Heat Transfer In Nanoscale Liquid Bridge
TL;DR: In this paper, the authors investigated heat transfer in a nanoscale liquid-argon bridge between planar gold surfaces using molecular dynamics simulation and continuum analysis and found that heat transfer is significantly less efficient than in the bulk.

Physical Foundations of Mesoscale Continua
TL;DR: In this paper, the authors define mesoscale continuum kinematics from the micro-scale kinematic model and derive a power balance for each of the three types of models: mass, lattice and granular.

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.
