Functionalized Silicas for Metal-Free and Metal-Based Catalytic Applications: A Review in Perspective of Green Chemistry.

Heterogeneous catalysis plays a key role in promoting green chemistry through many routes. The functionalizable reactive silanols highlight silica as a beguiling support for the preparation of heterogeneous catalysts. Metal active sites anchored on functionalized silica (FS) usually demonstrate the better dispersion and stability due to their firm chemical interaction with FSs.

[Cytochrome p450 genes and their application in plant improvement].

Cytochrome P450s are heme-containing mixed-function oxidases,involving in lots of biochemical reactions. They play an important role in preventing plants from pathogen and insect attacks and environmental stress. Sequence analysis of genomes has revealed that P450 is a gene super-family.
