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.....

Due to huge size of the raw digital video data (or image sequences), compression must be applied such data so that they may be transmitted and stored. There have been many important video compression standards, including the ISO/IEC MPEG-1, MPEG-2, MPEG-4 standards and the ITU-T H.261, H.263, H.263+.....

One of the known routes for the delivery of drugs into the human or animal body is pulmonary drug delivery, for example through nasal sprays or tracheal instillation. However, such method is very wasteful and a relatively large amount of the drug is necessary to ensure that the correct dose is recei.....

Fluorescent lamp is a common form of illumination in offices, public areas and even households. However, it is much harder to provide dimmable control for fluorescent lamps when compared with incandescent ones. A new method is now invented in achieving control over dimming function for fluorescent.....

Almost all circuit systems require a voltage reference. A voltage reference provides a temperature and supply independent voltage. In addition, this voltage reference mudt be able to operate under low-voltage low-power conditions and can be implemented in standard CMOS process instead of expensive B.....
