On the Description of Ordering in Liquid Crystals

چکیده
We inlrOduee the description of translational, orientational and internal order parameters in liquid crystals. We give a systcmatic approach 10 the identification of the relevant paramctcrs as cxpansion coefficients of the singlct distribution function in a suitable basis seL The construction of approximate distnOutions from a limited set of order paramcters using the maximum cnuopy principle is discussed. We lreal in detail order parameters and distribution functions for three cases: rigid molccules with cylindrical or biaxial symmeuy and non-rigid molecules with onc intcrnal rotor dissolved in various mcsophases.

Electrically switchable cylindrical Fresnel lens based on holographic polymer-dispersed liquid crystals using a Michelson interferometer
Fabricating an electrically switchable cylindrical Fresnel lens based on holographic polymer-dispersed liquid crystals (H-PDLC) using a Michelson interferometer is reported. Simplicity of the method and possibility of fabricating different focal length lenses in a single set up are among the advantages of the method. It is demonstrated that the Fresnel structured zone plate acts as a cylindrica...
متن کاملEffect of temperature on wet agglomeration of crystals
Objective(s):This study dealt with the wet agglomeration process in which a small quantity of binder liquid was added into a suspension of crystals, directly in the stirring vessel where the crystallization took place. The purpose of this investigation was evaluation of the effect of temperature on the agglomeration process in order to gain insight into the mechanism of the formation of the agg...
متن کاملUnusual sequences of tilted smectic phases in liquid crystals of bent-shape molecules.
The first theoretical description of the experimentally often-observed isotropic-polar smectic phase transitions of symmetric and asymmetric bent-shape molecules is presented. The isotropic-tilted polar smectic phase transition requires a coupling among three types of ordering processes: polar packing, director tilt, and layer ordering. For explaining the unusual triclinic-monoclinic phase tran...
متن کاملEnergetic and Entropic Contributions to the Landau–de Gennes Potential for Gay–Berne Models of Liquid Crystals
The Landau–de Gennes theory provides a successful macroscopic description of nematics. Cornerstone of this theory is a phenomenological expression for the effective free energy as a function of the orientational order parameter. Here, we show how such a macroscopic Landau–de Gennes free energy can systematically be constructed for a microscopic model of liquid crystals formed by interacting mes...
متن کاملMonitoring the differential ordering of enantiomers included into cyclodextrins through deuterium NMR in lyotropic liquid crystals.
Deuterium NMR in an aqueous non-chiral liquid crystal allows the discrimination of enantiomers through their ordering inside beta-cyclodextrins.
