A new switched-opamp technique is proposed to operate switched-capacitor circuits at supply voltages as low as 1-V without on-chip voltage multiplier or low-Vt devices. The main idea of the new switched-opamp technique is to implement an additional switchable operational amplifier (opamp) in parall.....

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.....

The present invention relates to a new method for the synthesis of triaroylbenzene by secondary amine and DMF-catalyzed cyclotrimerization of acetylenes. This method can be applied for the synthesis of new branched organic materials and polymers containing the triaroylbenzene moieties. The polymeriz.....
