M. V. Barkova,A. S. Strekalovskiydvanced to a level, still rapidly developing, where relatively large systems, including periodic systems, can be handled by all-electron calculations from the first principles. It is now possible to optimize geometries of zeolites with different cations and framework substituents and to predict their structural and electronic properties.

Laurence Mann,Jieun Kiaer,Emine Çakır) induce changes in the reactivity at the metal oxide due to the confinement of reactants/products in the zeolite cavities. These aspects are discussed with reference to Cu-, Fe-, V- and Mocontaining micro- and mesoporous materials in order to evidence prospects, but also limitations for the application of this new class of catalytic materials.

This subject istreated to an extensive review, showing how an understanding of it isessential to the development of a new generation of solid catalysts.There are also exciting opportunities to shape

Applications to Natural Resources,olitic ring with two Al ions, the sites with distantly placed aluminiums were also studied. It was shown that the latter tend to form oxygen bridged zinc cationic pairs. Such sites, as well as small zinc oxide clusters, exhibit a different enhanced reactivity towards alkanes compared to single zinc ions in cationic positions.
