    Sammanfattning : In light of its rapidly growing energy demand, human society has an urgent need to become much more strongly reliant on renewable and sustainable energy carriers. Molecular hydrogen made from water with solar energy could provide an ideal case. LÄS MER

  4. 3. Biomimetic Iron Complexes involved in Oxygenation and Chlorination : A Theoretical Study

    Författare :Holger Noack; Margareta R. A. Blomberg; Per E. M. Siegbahn; Martin Kaupp; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biomimetic; iron; density functional theory; intradiol; chlorination; adpic acid; diamond core; reactivity; Bio-inorganic chemistry; Bio-oorganisk kemi; Theoretical chemistry; Teoretisk kemi; kemisk fysik; Chemical Physics;

    Sammanfattning : Biomimetic chemistry is directed towards the simulation of enzymatic reactivity with synthetic analogues. In this thesis a quantum chemical method has been employed to study the mechanism of highly reactive iron-oxo complexes involved in oxygenation and chlorination of organic substrates. LÄS MER

  5. 4. Oxidized Lipids and Lysosomal Pathology in Atherogenesis

    Författare :Wei Li; Wendy Jessup; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Macrophages take up large amount of exogenous materials such as oxidatively modified low-density lipoproteins (oxLDL) and lysosomotropic agents. OxLDL is taken up into macrophage lysosomes through receptor-mediated endocytosis, but poorly degraded, resulting in foam cell formation. LÄS MER

  7. 5. Molecular Approaches to Photochemical Solar Energy Conversion : Towards Synthetic Catalysts for Water Oxidation and Proton Reduction

    Författare :Gerriet Eilers; Reiner Lomoth; Leif Hammarström; Wolfgang Lubitz; Uppsala universitet; []
    Nyckelord :Physical chemistry; artificial photosynthesis; solar fuel; WOC; OEC; accumulative electron transfer; hydrogenase mimic; oxygen evolution; proton reduction; water oxidation; Fysikalisk kemi;

    Sammanfattning : A molecular system capable of photoinduced water splitting is an attractive approach to solar energy conversion. This thesis deals with the functional characterization of molecular building blocks for the three principal functions of such a molecular system: Photoinduced accumulative charge separation, catalytic water oxidation, and catalytic proton reduction.
