Designer zeolites

Mesostructured zeolites: bridging the gap between zeolites and MCM-41.

Surfactant-templating is one of the most versatile and useful techniques to implement mesoporous systems into solid materials. Various strategies based on various interactions between surfactants and solid precursors have been explored to produce new structures. Zeolites are invaluable as size- and shape-selective solid acid catalysts. Nevertheless, their micropores impose limitations on the ma...

‘Designer’ babies

The remaining hurdle to the creation of babies specifically to save the life of an ailing brother or sister was removed in Britain last month by the fertility regulatory body to the delight of afflicted families and alarm of those who fear the advent of a 'designer' baby age. The decision of the UK's Human Fertilisation and Embryology Authority gives new hope to the parents of a two-year-old bo...

Zeolites: Large molecules welcome.

Many eff orts to improve the performance of heterogeneous catalysts and adsorbents focus on creating materials that are highly active and selective for their target reactants and products. Th is typically involves the use of porous solids with high surface areas, for instance crystalline or amorphous inorganic compounds, whose diff usional access, adsorption, and reaction properties depend stro...
