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

Structural analysis of water and carbon tetrachloride adsorbed in activated carbon fibres
Małgorzata Śliwińska-Bartkowiak,Henryk Drozdowski,Mateusz Kempiński,Monika Jażdżewska,Yun Long,Jeremy C. Palmer,Keith E. Gubbins +6 more
TL;DR: X-ray diffraction studies of water and carbon tetrachloride adsorbed in nanoporous activated carbon fibres suggest that very high pressures arise within the pores, as has been observed in molecular simulations, and may give rise to the large change in electronic properties of the fibres after adsorption of guest molecules.

Capillary imbibition of confined water in nanopores
TL;DR: Zeng et al. as discussed by the authors investigated the spontaneous capillary imbibition of confined nanopores using an analytical model that includes the slip effect, wettability and effective viscosity at the water surface interface.

Nanoconfining affinity materials for pH-mediated protein capture–release
TL;DR: Novel types of functional materials, nanoconfining affinity materials (NCAMs), which rely on the nanoconfinement effect of porous materials with pore sizes comparable to the molecular sizes of proteins to provide dominant affinity were reported.

Hydrogen-Bond-Induced Supermolecular Assemblies in a Nanoconfined Tertiary Alcohol
TL;DR: Morineau et al. as mentioned in this paper showed that the self-association of terbutanol-like supermolecular clusters in a nanoconfined geometry can survive under confinement despite the absence of a prepeak.

New approaches to measure interfacial rheology of confined fluids
Ali Dhinojwala,Steve Granick +1 more
TL;DR: Several instrumental developments to examine the rheology of ultrathin confined liquids are described in this paper, including capacitance sensing of the film thickness, concurrent measurement of normal and shear forces by piezoelectric methods, application of periodic forces in the normal direction to determine dynamic oscillatory shear moduli, and quantification of apparatus misalignment.

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.
