Studies of these phases are of importance in a wide range of scientific fields and as such have stimulated considerable theoretical ...
The liquid crystal cell used a cholesteric-nematic mixture with positive dielectric anisotropy (CN cell) has a cholesteric phase at the off-state when molecules of liquid crystals near the electrode surfaces were aligned perpendicular to them by using surface treatment. The cholesteric phase at the ...
A liquid-crystal phase, characterised in that it contains at least one component of the formula I <IMAGE> in which R<1> is alkyl having 1 to 12 carbon atoms, R<2> is alkyl, alkoxy or alkanoyloxy, in each case having 1-12 carbon atoms, Cy is trans-1,4-cyclohexylene, and Ph is...
Phase transitions in thin (1.5–3 μm) planar cells of a ferroelectric liquid crystal (FLC) mixture are studied using the optical second harmonic generation (SHG) technique. This method is well known because of its high sensitivity to the structural and electronic properties of surfaces, ...
Novel liquid-crystal phase-transition behavior at the chiral nematic-smectic-A-smectic-C point New phenomenology of the chiral nematic (N), smectic-A (A), ferroelectric smectic-C (C) point (NAC) is reported in a binary mixture of two chiral component... DS Parmar,NA Clark,DM Walba,......
In the dimer case, a clear isotropic-ordered phase transition is observed whereas such a clear transition is absent in monomers. 展开 关键词: Molecular simulation Liquid-crystal Hard prolate ellipsoid DOI: 10.1016/S0378-3812(01)00666-5
Effects on thermo-optical properties of the composition of a polymer-stabilised liquid crystal with a smectic A-chiral nematic phase transition. Liq. Cryst. 35, 1151–1160 (2008). CAS Google Scholar Seo, D. S., Matsuda, H., Oh-ide, T. & Kobayashi, S. Alignment of nematic liquid ...
Liquid crystal actuators conventionally undergo shape changes across an order‐disorder phase transition between liquid crystal (LC) and isotropic phases. In this study, we introduce an innovative Liquid Crystal Polymer (LCP) actuator harnessing an order‐order LC phase transition mecha...
Orientational order in the vicinity of a second order smectic-A to nematic phase transition Measurements of the quadrupolar splitting of the central N 14 are reported for the liquid crystal NBOA. The splitting is a measure of the orientational ord... B Cabane,WG Clark - 《Solid State Communic...
Liquid-phase epitaxy (LPE) is a solution crystal growth technique for the deposition of crystallographically oriented thin films, thick layers, or discrete crystals on a seeding or template substrate. From: Handbook of Crystal Growth: Thin Films and Epitaxy (Second Edition), 2015 ...
