"Modeling the Complexities of Heterogeneous Catalysts"

In the past several decades, surface science methodologies have contributed significantly to our understanding of reaction mechanisms of heterogeneous catalysts. From fundamental studies on metal single crystals to investigations of metal oxide supported metal clusters, the relative complexities of model catalyst systems have continued to evolve in complexity and likeness to industrial catalysts. Fundamental studies of reactive systems on metal single crystals have aided researchers in understanding the effect of surface structure on catalyst reactivity and selectivity for a number of important reactions. More recently model systems consisting of metal clusters deposited on planar oxide surfaces under ultra high vacuum conditions have facilitated the study of metal particle size and support effects. These model systems are useful for carrying out kinetic investigations, yet are amenable to surface spectroscopic techniques, thus enabling investigations under realistic pressures and at working temperatures. This talk will present selected investigations of catalytic reactions on single crystal and model supported catalysts with emphasis on recent work addressing the nature of the active site in catalysis by mixed-metals.

Veniamin Davydovich Kalner, Ecological paradigm as it is seen by an engineer


The necessary participation of each man in the preservation and rehabilitation of the nature and environment is discussed. The discussion is based on public papers and estimation of anthropogenic impacts.

The author uses his engeneer’s and researcher’s exact knowledge to describe the modern concept of the visual environment. The history of introduction and development of term ecology and its philosophic generalization was analyzed to formulate the concepts of ecological culture and outlook as the basis for development and creation of modern products and services. The reasons for aggravation of the ecological crisis and nature degradation are identified, ways to abate them considered. The lecture will be of interest to those who are anxious about the catastrophic contamination and degradation of the environment.
