    Sammanfattning : Artificial photosynthesis requires catalysts for efficient and selective conversions of small molecules. Molecular catalysts are advantageous to use in these instances as they offer precise control over chemical reactivity. LÄS MER

  3. 7. Advances in Stereoselective Palladium(ΙΙ)-Catalyzed Oxidative Transformations of Allenes

    Författare :Daniels Posevins; Jan-Erling Bäckvall; Troels Skrydstrup; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Synthesis; Palladium Catalysis; Allenes; Biomimetic; Carbocyclization; Borylation; Carbonylation; Oxidation; Heterogeneous; organisk kemi; Organic Chemistry;

    Sammanfattning : Palladium(ΙΙ)-catalyzed carbon-carbon and carbon-heteroatom bond formation via selective C-H bond oxidation constitutes a step-economical and versatile approach towards complex target molecules. This thesis has been focused on the development of new selective palladium(ΙΙ)-catalyzed transformations of allenes under oxidative conditions catalyzed by either homogenous or heterogeneous palladium(ΙΙ) catalysts.

  4. 8. Cartilage Oligomeric Matrix Protein (COMP). Functions in collagen binding and assembly

    Författare :Krisztina Rosenberg; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical biology; Klinisk biologi;

    Sammanfattning : Connective tissues contain a prominent extracellular matrix that provides mechanical and physical properties. This extracellular matrix contains as a major constituent a network of collagen fibres. These are composed of collagen fibrils, which in turn are assembled from many collagen molecules aligned parallel to each other. Several proteins, e. LÄS MER

  5. 9. Interrogating Diffusional Mass and Charge Transport in Catalytic Metal-Organic Frameworks

    Författare :Ben A. Johnson; Sascha Ott; Nicolas Plumeré; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal-organic frameworks; molecular catalysis; reaction-diffusion; electrochemistry; water oxidation; charge transport;

    Sammanfattning : Molecular catalysts are efficient and selective for the electrochemical conversion of small molecules for energy conversion. Application of molecular species in a large-scale industrial setting requires stabilization in a heterogeneous support material. LÄS MER

  7. 10. Mimicking the Outer Coordination Sphere in [FeFe]-Hydrogenase Active Site Models : From Extended Ligand Design to Metal-Organic Frameworks

    Författare :Sonja Pullen; Sascha Ott; Patrick L. Holland; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; [FeFe]-hydrogenases; outer coordination sphere; model complexes; biomimetic catalysis; artificial photosynthesis; metal-organic frameworks;

    Sammanfattning : Biomimetic catalysis is an important research field, as a better understanding of nature´s powerful toolbox for the conversion of molecules can lead to technological progress. [FeFe]-hydrogenases are very efficient catalysts for hydrogen production. These enzymes play a crucial role in the metabolism of green algae and certain cyanobacteria. LÄS MER
