This is about a new scheme for driving reflective bistable cholesteric displays (BCDs). It relies on fast switching from the planar state to the focal conic (FC) state, the two stable states in BCDs. The new scheme allows BCDs be driven using simpler electrical wave forms, and also making line add.....

A variety of new mesogen-containing acetylenes are prepared and designed. A research team at the HKUST developed new catalyst systems for polymerizing the functional acetylene monomers and manufactured the novel liquid crystalline polyacetylenes. In this new invention, the new side-chain liquid cr.....

Flue gases produced in combustion processes, such as coal-fired power plants, automobiles, smelters, etc., contains huge amount of nitrogen and sulfur oxides, carbon monoxide and particulates. They contribute significantly to atmospheric pollution and some of them are stringently controlled by legis.....

Retinoic acid (RA) induces the differentiation of many cell types such as epithelial cells and cancer cells. Clinically, RA has been demonstrated to be efficacious in the treatment of promyelocytic leukemia, a type of blood disease. RA has also been shown to affect patterning and neurogenesis in viv.....
