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

Solid or liquid? Solidification of a nanoconfined liquid under nonequilibrium conditions.
TL;DR: It is shown that a model-confined liquid can behave both as a Newtonian liquid with very little change in its dynamics and as a pseudosolid, depending solely on the rate of approach of the confining surfaces.

Under pressure: Quasi-high pressure effects in nanopores
TL;DR: In this article, the authors developed two models to study the pressure tensor of an argon nanophase confined in carbon micropores by molecular simulation, and showed that the in-pore tangential pressure is positive and on the order of 10 4 Â bar, while the normal pressure can be positive or negative depending on pore width, with a magnitude of ∼10 3 Âbar at ambient bulk pressure.

Dissipation and oscillatory solvation forces in confined liquids studied by small-amplitude atomic force spectroscopy
TL;DR: Conservative and dissipative tip-sample interaction forces are determined from the amplitude and phase response of acoustically driven atomic force microscope cantilevers using a non-polar model fluid and atomically flat surfaces of highly ordered pyrolytic graphite.

Characterization of Water Confined between Silica Surfaces Using the Resonance Shear Measurement
Motohiro Kasuya,Masaya Hino,Hisho Yamada,Masashi Mizukami,Hiroyuki Mori,Seiji Kajita,Toshihide Ohmori,Atsushi Suzuki,Kazue Kurihara +8 more
TL;DR: In this article, the authors performed the resonance shear measurement (RSM) for evaluating the properties of water confined between silica surfaces with and without water vapor plasma treatment, which was used to increase the density of the silanol groups on the surfaces.

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.
