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.....

In recent years the demand for small cellular handsets has grown substantially and the need for still smaller handsets continues to increase. Planer inverted-F antenna (PIFA) designs have received attention since they are compact. Although smaller sizes PIFA are needed, the design of compact antenna.....

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.....
