The dependence of the temperature of crystal-liquid phase transition on the size and shape of simple nanocrystalThe dependence of melting temperature T m on the size and shape of an n -dimensional nanocrystal of elementary single-component substance is studied. The nanocrystal has the form of an...
Furthermore, the correlation in the positioning of the layers dies away algebraically (as an inverse power of the distance) rather than being constant as in a true crystal. In liquid crystals having both nematic and smectic A phases, the nematic phase is the higher temperature phase. It is ...

liquid crystal phase transitionspolarizing microscopeparamorphotic phase transitionsA temperature scanning attachment for the polarizing microscope is described that offers a simple but powerful technique with which to detect even subtle paramorphotic phase transitions in liquid crystals with high temperature ...
Local self-consistent approach to the phase transition at the nematic liquid-crystal-wall interface The surface tension of nematic origin is calculated near the bulk transition temperature. It is estimated to be one order of magnitude smaller than the ... G Barbero,LR Evangelista - 《Physical Rev...
Liquid Phase Sintering In subject area: Engineering Liquid phase sintering is a consolidation technique of powder compacts containing more than one component at a temperature above the solidus of the components and hence, in the presence of a liquid.

An object of the present invention is to provide a polymerizable liquid crystal composition incorporating a polymerizable liquid crystal compound which displays a low nematic phase temperature, displays excellent compatibility with other... O Naoki,L Seungtaeg,H Hiroshi,... 被引量: 0发表: 2008年 ...
pioneered a polymer stabilized BP (PSBP) system in which the BPs were stabilized by polymer networks, obtaining a wide temperature range of over 60.0 °C (~53.0 to −13.0 °C)1. This PSBP was applied by the Samsung Co. in 2008 to demonstrate the first BP liquid crystal ...
