TLDR
Both simple and more complex adsorbates that are confined in various environments (slit or cylindrical pores and also disordered porous materials) are considered and how confinement affects the glass transition is addressed.Abstract:
We present a review of experimental, theoretical, and molecular simulation studies of confinement effects on freezing and melting We consider both simple and more complex adsorbates that are confined in various environments (slit or cylindrical pores and also disordered porous materials) The most commonly used molecular simulation, theoretical and experimental methods are first presented We also provide a brief description of the most widely used porous materials The current state of knowledge on the effects of confinement on structure and freezing temperature, and the appearance of new surface-driven and confinement-driven phases are then discussed We also address how confinement affects the glass transitionread more

Complex plasmas: An interdisciplinary research field
TL;DR: Complex (dusty) plasmas are composed of a weakly ionized gas and charged microparticles and represent the plasma state of soft matter as discussed by the authors, and they can be easily manipulated in different ways, also at the level of individual particles.

The Physics of the Colloidal Glass Transition
Gary L. Hunter,Eric R. Weeks +1 more
TL;DR: A review of the current state of understanding of the colloidal glass transition, with an emphasis on experimental observations, is given in this paper, where the authors describe features of colloidal systems near and in glassy states, including increases in viscosity and relaxation times, dynamical heterogeneity and ageing.

Introduction to Phase Transitions and Critical Phenomena
TL;DR: There has been a lot of experimental and theoretical work on the nature of critical phenomena in the neighbourhood of second order phase transitions as discussed by the authors, but it has not been easy to get a good overall view of this work without digging through the rather complex original literature, although there are some good review articles covering particular aspects of the work.

Nanoconfined Ionic Liquids
TL;DR: A comprehensive review of nanoconfined ILs, a new class of composites with the intrinsic chemistries of ILs and the original functions of solid matrices, highlighting the potential applications in diverse fields, including catalysis, gas capture and separation, ionogels, supercapacitors, carbonization, and lubrication.

Calculations of hyper-Raman tensor components of alkali halides
TL;DR: In this article, a weak cubic anisotropy of the hyper-Raman tensor is found for the LO mode and the lattice and electro-optic contributions to hyper-raman scattering are predicted to be of the same order of magnitude.

Dielectric normal mode relaxation of poly(propylene glycol) melts in confining geometries
Andreas Schönhals,R Stauga +1 more
TL;DR: In this article, the authors used dielectric spectroscopy to study the molecular dynamics of oligomeric poly(propylene glycol) (PPG) liquids (MW=1200, 2000 and 4000 g/mol) confined to porous glasses (pore dimensions 2.5, 5.0 and 7.5 nm).

Polar gyroscopic tests of general relativity.

TL;DR: Gyroscopic precession at the terrestrial poles is treated using the original Kerr metric in Cartesian coordinates and an isometry method for treating accelerating observers to corroborate predictions obtained by gravitomagnetic methods.

Freezing/melting behaviour within carbon nanotubes
TL;DR: In this paper, the freezing and melting of fluids confined within multi-walled carbon nanotubes with an internal diameter of 5 nm was studied using experimental measurements and molecular simulations, showing that the adsorbate forms concentric layers that solidify into quasi-two-dimensional hexagonal crystals with defects.

Solidification of Lennard-Jones Fluid in Cylindrical Nanopores and Its Geometrical Hindrance Effect: A Monte Carlo Study
TL;DR: In this article, the authors investigated the freezing phenomena of LJ methane confined in cylindrical nanopores of reduced pore diameter ranging from 4.5 to 9.5 with saturated vapor as equilibrium bulk condition and found that the arrangement of the LJ particles in frozen state formed a hexagonal array within each concentric circular layer.
