  2. 16. Low temperature CO oxidation over Pt/CeO2

    Author : Noemi Bosio; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Heterogeneous catalysis; Cerium oxide; CO oxidation; kinetic Monte Carlo; density functional theory;

    Abstract : The oxidation of CO to CO2 is a widely studied reaction not only for its practical applications but also for its apparent simplicity. CO oxidation is, in fact, often used as a model reaction for other oxidation reactions. READ MORE

  5. 18. Ca-Pd/Pt-Ge Compounds on the Zintl Border

    Author : Isa Doverbratt; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Zintl compounds form a category in intermetallic chemistry somewhere between metallic and ionic compounds. Classical Zintl compounds form between electropositive and electronegative elements, such as the alkaline earth metals and the p-block elements, i.e. elements with a relatively large electronegativity difference.

    Abstract : Almost precisely a century ago, in the 1920s and 1930s, cattle bled to death in North America after being fed moldy hay containing sweet clover, the yellow Melilotus officinalis, and the white Melilotus albus. The toxic substance in the hay inhibiting blood coagulation was identified and named dicumarol. READ MORE

  7. 20. Studies of NOx Storage Catalysts - Preparation, Characterization, Sulfur Deactivation and Micro Kinetic Modelling

    Author : JAZAER DAWODY; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kinetic modelling; metal oxide additives; NO oxidation; Zeta potential; FTIR; SO2 oxidation; Al2O3; NOx storage and reduction catalysts; TEM; BaCO3; SEM; Pt precursors; sulfur deactivation;

    Abstract : For the protection of the global environment, it is essential to decrease the emissions of CO2 which is a green house gas. Lean-burn and diesel engines offer relatively low CO2 emissions and good fuel economy. READ MORE
