Asymmetric reactions on chiral catalysts entrapped within a mesoporous cage.
The encapsulation of homogeneous chiral catalysts, e.g. Co(Salen) and Ru-TsDPEN, in the mesoporous cage of SBA-16 is demonstrated; the encapsulated catalysts show performance as good as that of the homogeneous catalysts, and can be recycled for more than 10 times without significant loss of catalytic performance.
متن کاملPorous organic cage stabilised palladium nanoparticles: efficient heterogeneous catalysts for carbonylation reaction of aryl halides.
Porous organic cage stabilised palladium nanoparticles were successfully prepared using methanol as a mild reductant. The as-prepared porous composite materials show high catalytic activity for the carbonylation reaction of aryl halides under mild conditions.
متن کاملCage Culture: Species Suitable for Cage Culture
for cage culture. Species which have been researched and successfully reared in cages in the southeastern region of the U.S. include: catfish, trout, tilapia, striped bass, red drum, bluegill sunfish, crappie, and carp. Other species may be suitable for cage culture but research has lagged behind other aquaculture research in recent years. Interest in cage culture has been revived as an alterna...
متن کاملA breeding cage for cats.
During the course of establishing a new cattery an opportunity arose to design and test cages suitable for littering and rearing kittens. The object was to reduce the transfer of respiratory infection from one litter to another while providing good environmental conditions for the queen and her litter. The cage had to occupy a minimum of space consistent with these requirements, and be light en...
متن کاملA review of the status and development requirements for cage Aquaculture in Iran and the world
In recent years, cage aquaculture has been introduced as modern technology in the world. Although the use of cages for fish’s holding and transporting for short periods can return two centuries ago in Asian, commercial cage aquaculture was pioneered in Norway in the 1970s and 1980s. Today, due to population growth, climate change and more attention to the productivity of water use in the aquacu...
