Bacillus subtilis has been widely used for extracellular production of native and homologous proteins. Based on the use of a synthetic expression/secretion cassette, a new bacterial expression system is developed and may be applied to produce heterologous proteins efficiently as secreted products. .....

The operational frequency of existing magnetoelectric materials having metallic or ceramic magnetostrictive materials and ceramic piezoelectric materials may be limited to a few kilohertz due to the presence of eddy-current losses in the metallic magnetostrictive phase. Further, these materials may .....

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.....

Ammonia (NH3) and odorous smell (nitrogen containing compounds) in the air are contaminants and are harmful to human health. Since more and more people concern for the indoor air quality after the outbreak of SARS, methods have been developed to eliminate the contaminants.Conventional supported meta.....

Programmed cell death is a very important cellular process that is critically involved in many diseases. A key step in the programmed cell death is the activation of a series of intracellular proteases, such as caspase-3. The invention is a novel method of detecting the early stage of programmed cel.....
