Partial Oxidation of Hydrocarbons Over Ceria Zirconia Catalysts
… research along several avenues pertaining to oxidation reactions. First, the major conclusions are summarized from a perspective describing active oxygen species on catalyst surfaces. Some oxygen species are more selective than others and if these species were better understood, a catalyst …

Exploration of Chemical and Biochemical Mechanisms of Catalysis
Nature uses proteins to catalyze a wide range of chemical processes that control cellular signaling. One such enzyme is ERK2 which plays a role in the transmission of signals by catalyzing the phosphorylation of its substrates. The signaling pathway that it is a part of is important in the control …

The transport and remote oxidation of compartment fire exhaust gases
The majority of deaths and injuries in compartment fires result from inhalation of the toxic gas, carbon monoxide (CO), especially in locations remote from the burning compartment. This causes the transport and oxidation of CO in burning buildings to become an important topic. Studies have been …

Synthesis and characterization of metal reagents mediating C-X activation (X=Cl, H) of hydrocarbons
… thesis develops methodology for the activation of C-X (X=H, Cl) bonds by transition metals. 2/4-Substituted alkyl pyridines such as cyclohexyl, adamantyl, hydroxyethyl and hydroxymethyl pyridines have been synthesized in moderate to good yields using [Fe<sup>II</sup> (Pic)₂(Py)₂] as a catalyst …

Getting to the Point: Bridging the Gap between Simple and Complex Catalytic Systems using Temporal Analysis of Products (TAP)
One of the key issues in the field of catalysis is to relate the catalyst structure/composition to its activity/selectivity. One way to understand this relationship is to understand the individual role each catalyst component plays in the chemical reaction. Industrial catalysts can be extremely …

Band engineering of metal oxide heterostructures for catalysis applications
… oxides are used as catalysts for a wide variety of industrially and environmentally important reactions such as the selective oxidation of hydrocarbons and alcohols and the selective catalytic reduction of nitrogen oxides. The support often plays an important role in the activity and selectivity …

Statistical description of turbulent reacting media
Present work concerns the interaction of chemistry and turbulence in a turbulent reacting flow. Both self-ignition and flame propagation are studied. For self-ignition study, the combined effects of temperature/concentration inhomogeneities and turbulence were studied numerically. For this purpose …
