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

Measurement of viscoelasticity of UV photoresist used for nanoimprint lithography under confinement in nanometer-sized gaps
TL;DR: In this article, the authors measured the viscoelasticity of a UV photoresist, PAK-01, confined in nanometer-sized gap widths by the sensitive shear force measurement method developed in their previous study.

A new method for measurement and quantification of tracer diffusion in nanoconfined liquids
V J Ajith,Shivprasad Patil +1 more
TL;DR: Development of a novel instrument to measure tracer diffusion in water under nanoscale confinement finds that the diffusion of a tracer molecule is slowed down by more than 10 times for the probe-substrate separations of 5 nm and below.

Melting of atomic layers in carbon nanotubes
Lucyna Firlej,Bogdan Kuchta +1 more
TL;DR: In this article, the melting temperature of a monolayer adsorbed in the pore is lower than the temperature of the 3D triple point, however, the adsorption of the second layer pushes the temperatures of melting of the contact layer up.

Solidification of the Lennard-Jones fluid near a wall in thermohydrodynamic lubrication
TL;DR: The thermohydrodynamic lubrication of the Lennard-Jones (LJ) fluid in plain wall channels is investigated by using a molecular-dynamics simulation and it is found that the LJ fluid solidifies near the wall when the viscous heating of the L J fluid in the bulk regime is sufficiently large.

The friction and lubrication of solids
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.
