  1. 16. Transition Metal Hydrides : Biomimetic Studies and Catalytic Applications

    Författare :Jesper Ekström; Hans Adolfsson; Jonathan Williams; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transition metals; catalysis; bioinorganic chemistry; hydrides; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Sammanfattning : In this thesis, studies of the nature of different transition metal-hydride complexes are described. The first part deals with the enantioswitchable behaviour of rhodium complexes derived from amino acids, applied in asymmetric transfer hydrogenation of ketones. LÄS MER

  3. 17. Blue Laser Source for Laser-Induced Fluorescence

    Författare :Jesper Holm; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Second Harmonic Generation; Lasers; PPKTP; ALA; Tapered laser diodes; External cavity lasers; Laser-induced fluorescence; photodynamic therapy; mTHPC;

    Sammanfattning : Laser-induced fluorescence is a clinical diagnostic tool, used for tumor demarcation and detection. The technique relies on the injection or topical application of a light sensitive drug called a photosensitizer. This substance has the ability to be accumulated to higher concentrations in cancer cells than in normal cells. LÄS MER

  4. 18. Light-Induced Routes to Sustainable Biocrudes for Fuels and Lubricant Oils

    Författare :Leandro Cid Gomes; Henrik Ottosson; Norbert Hoffmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aviation fuels; triplet sensitization; photoacid; renewable energy; photochemistry; Kemi; Chemistry;

    Sammanfattning : Fossil-based hydrocarbons are at present the ideal compounds for jet fuels and lubricant oils, so their replacement by novel technologies is not easy. Instead, sustainable routes to hydrocarbons, such as sunlight-driven processes, are desired to reduce the environmental impact by the transport sector. LÄS MER

  5. 19. Mimicking Photosystem II with Manganese Model Complexes to Approach Artificial Photosynthesis

    Författare :Joakim Högblom; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Hydrogen; EPR; Cobalt; Biokemi; metabolism; Biochemistry;

    Sammanfattning : The work in thesis aims for artificial photosyntesis, which could and will mimic natural photosynthesis, the process that uses light to create energy rich compounds from H2O and CO2. Water is oxidized in Photosystem II (PSII) by the Water Oxidizing Complex (WOC), which is a catalytic site on the lumenal side of the thylakoid membrane. LÄS MER

  7. 20. Exploring nanosystems for biomedical applications focusing on photodynamic therapy and drug delivery

    Författare :Vladimir Kirejev; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photodynamic therapy; PDT enhancement; Nitric oxide; NO-based PDT; Targeted drug delivery; Galectin-3; mTHPP; Cyclodextrin; CD-mTHPP conjugate; PpIX AuNP combination; Two-photon microscopy; FLIM; Cell phototoxicity; Ex vivo skin;

    Sammanfattning : The increasing incidences of cancer and related deaths call for the development of new and improved treatment modalities. Photodynamic therapy (PDT) today is an alternative to conventional treatments, but has limitations. This thesis explores different nanosystems with aim to improve PDT focusing on spectroscopic and ex vivo studies. LÄS MER
