  2. 21. Fabrication, functionalization and electrical conductance modulation of nanoparticle based molecular electronic Nano-devices

    Author : Ishtiaq Hassan Wani; KLAUS LEIFER; Silvia Karthäuser; Uppsala universitet; []
    Keywords : Molecular electronics; gas sensor; hybrid materials; place exchange; random telegraph signal;

    Abstract : Over the years many techniques have been proposed for the purpose of the formation of electrically conducting metal-molecule-metal junctions. One such technique utilizes gold-nanoparticles (AuNPs) that could assist in contacting small molecules between large gaps. READ MORE

  4. 22. Exhaust aftertreatment under lean conditions, regenerable SOx traps and NOx reduction catalysts

    Author : Lisa Kylhammar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heterogenous catalysis; Selective catalytic reduction; HC-SCR; Sulfur storage; SOx trap; Spectroscopy; Lean exhausts; NOx; Ag Al2O3; DRIFT; XPS;

    Abstract : The aim of this thesis was to investigate i) potential materials for regenerable SOx traps and ii) the influence of silver distribution within Ag/Al2O3 catalysts on the selective reduction of NOx by hydrocarbons (HC-SCR). Both areas are highly relevant for present and future vehicle aftertreatment technologies for lean exhausts. READ MORE

  5. 23. Oxy-Fuel Combustion - The Control of Nitrogen Oxides

    Author : Fredrik Normann; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxy-fuel; NOx; O2 CO2; combustion; emission; nitrogen oxides;

    Abstract : Oxy-fuel combustion is one of the main candidates for carbon dioxide capture from power plants. In oxy-fuel combustion, oxygen diluted with recycled flue gas oxidizes the fuel. The elimination of air-borne nitrogen generates a flue gas that mainly consists of carbon dioxide and water. READ MORE

  6. 24. Transition Metal Mediated Transformations of Carboranes

    Author : Ludvig Eriksson; Kalman Szabo; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; carborane; isoquinoline; PK11195; peripheral bensodiazepine receptor; Cu I Iodide; iodinated carborane; palladium; isotopic exchange; Herrmann’s Catalyst; Heck reaction; Suzuki-Miyaura reaction; cross coupling; arylation; olefination; 125-iodine; radiolabelling; carboraneboronic ester; BNCT; 2-iodo-; Kemi; Chemistry; Kemi; organisk kemi; Organic Chemistry;

    Abstract : This thesis describes the use of copper and palladium to mediate transformations of carboranes, especially p-carborane.1-(1-p-carboranyl)-N-methyl-N-(2-butyl)-3-isoquinolinecarboxamide, a carborane containing analogue of the peripheral benzodiazepine receptor (PBR) ligand PK11195, has been synthesised.

  7. 25. Allylic alcohols and aziridines from alkenes : Studies in asymmetric catalysis

    Author : Mikael J. Södergren; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Enantioselective; allylic alcohols; epoxide rearrangement; lithium amides; desymmetrization; kinetic resolution; allylic oxidation; alkenes; aziridination; Kemi; Chemistry; Kemi; organisk kemi; Organic Chemistry;

    Abstract : The development of methodology for asymmetric catalytic transformation of alkenederivatives is summarized. The studies concern the [a] Cu(I)-catalyzed allylic oxidation,[b] isomerization of epoxides to allyl alcohols, and [c] Cu(I)-catalyzed alkeneaziridination, respectively.[a] The preparation of exo-2-azabicyclo[2.2.
