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

Self-Assembly of Alcohols Adsorbed on Graphene
Ronen Zangi,Ronen Zangi +1 more
TL;DR: In this paper, self-assembly in two dimensions (2D) can generate structures with no counterparts in three dimensions (3D); therefore, apart from its technological applications, this phenomenon is also theoretical.

An EQT-based cDFT approach for thermodynamic properties of confined fluid mixtures
TL;DR: This work uses the EQT-based grand potential to predict various thermodynamic properties of a confined binary mixture of hydrogen and methane molecules inside graphene slit channels of different widths and finds that graphene is selective to methane molecules.

Freezing point elevation in nanospace detected directly by atomic force microscopy
TL;DR: In this paper, a carbon microparticle was attached to the top of the cantilever tip, and its interaction force with cleaved graphite was measured within a liquid cell filled with organic liquid, controlled at a desired temperature above the bulk freezing point of the liquid.

Friction dynamics for curved solid surfaces with long-range elasticity
TL;DR: In this paper, a model that takes into account the effect of long range elasticity and applies it to study the boundary lubrication for curved solid surfaces is introduced, and the sliding dynamics when the block and the substrate are separated by a molecular thin lubrication film is discussed.

Confinement-induced fluid-gel transition in polymeric solutions.
TL;DR: The viscoelastic properties of confined polymer solutions are probed by particle-tracking microrheology and it is found that those quantities change continuously as the confinement increases, and, at severe conditions, when the constrain reaches the size of the polymer molecule, the system undergoes a transition from a visCoelastic fluid to a gel.

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.

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.
