Theoretical Investigations of Silver Clusters and Silver-Ligand Systems,-22] and experimental effort. One of the reasons is the (still) important role these systems play in the photographic process. Investigations of interactions of silver clusters with different atoms and molecules are motivated primarily by a possible utility of these clusters in catalytic pro

,Concepts In Double Groups — Do We Really Understand Them for Practical Applications?,ations appear in most applications for the classification of optical and magnetic energy levels, selection rules and spectral intensities using the conventional symmetry groups G. Bethe (1929) and Opechowski (1940) introduced matrix groups .G of twice the order of the ordinary groups .

Fractal Power Spectrum at Catalytic Oxidation of , over Supported , Catalyst,are of the type 1/. , where α. 1 at low frequency limit and α(.) slightly monotonically increases with the frequency. A new hypothesis for explanation of this behaviour is forwarded. This hypothesis involves two assumptions: . a new type of “interactions”, called non-perturbative, which are insensit

,In Situ Mössbauer Study of Mixed-Valency Catalysts for Methanol Oxidation,n situ by Mössbauer spectroscopy during the oxidation of methanol. The ferroferriborate exhibits two kinds of thermally activated electron exchange: direct (3d.Fe.↔3d.Fe.) and indirect (3d.Fe.↔O↔3d.Fe.) In Mg.Fe..Fe.BO. the direct exchange is blocked by Mg. ions and only indirect exchange (3d.Fe.↔O↔

Electronic Structure of Vanadia Systems: Systematic Theoretical Studies,tically enforced reactions involving V.O. include mild oxidation, ammoxidation and dehydrogenation of hydrocarbons and other organic compounds, oxidation of SO. to SO., naphthalene or oxylene to phthalic anhydride and more recently n-butane to maleic anhydride. Vanadia catalysts also seem promising
