TLDR
A wall-induced birefringence in a nematic liquid crystal above the nematicisotopic phase transition point has been observed for the first time in this article, and it is expected that this phenomenon will provide a useful tool to study the nature of aligning forces at liquid-crystal--solid interfaces.Abstract:

Surface effects and anchoring in liquid crystals
TL;DR: In this paper, a review focusing on nematic liquid crystals is presented, where three main kinds of effects can be distinguished: the perturbation of the liquid crystalline structure close to the surface, the bulk liquid crystal structure is recovered with an orientation which is fixed by the surface and critical adsorption or wetting can occur at surfaces.
Journal ArticleDOI
Density-functional theory of freezing and properties of the ordered phase
TL;DR: In this article, the authors review a theory of freezing based on the density-functional approach and compare a variety of its versions, and discuss the application of the theory to the freezing of various simple and complex fluids.

Surface Anchoring of Nematic Liquid Crystals
TL;DR: In this paper, the authors make a distinction between macroscopic and microscopic approaches toward the substrate-nematic interface, and the significance of the Gibbs' dividing surface is emphasized together with some thermodynamic properties of the anchoring strength and pretilt angle.

Modeling planar degenerate wetting and anchoring in nematic liquid crystals
TL;DR: In this paper, a simple surface potential favoring the planar degenerate anchoring of nematic liquid crystals was proposed, i.e., the tendency of the molecules to align parallel to one another along any direction parallel to the surface.
Journal ArticleDOI
The interfacial properties of a model of a nematic liquid crystal
TL;DR: In this article, a statistical-mechanical theory for the interfacial properties of molecular fluids characterized by strongly anisotropic pairwise potentials was developed, which is a generalization to molecular fluids of the mean-field (or van der Waals) theory of non-uniform fluids of spherical molecules.
