  2. 21. Life of Excitons in Artificial Photosynthetic Antennas

    Author : Johan Andersson; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zn-porphyrin; Osmium; Ruthenium; Polypyridine; Inter Ligand Energy Transfer; Inter System Crossing; Excited state dynamics; Transition metal complexes; Photosynthetic Antennas; Solar energy conversion; Artificial photosynthesis; Physical chemistry; Fysikalisk kemi; Transient Absorption Anisotropy.; Reaction Center; Dendrimer; Energy Transfer;

    Abstract : Due to the predicted energy crisis when fossil fuels will be exhausted it is important to search for alternative energy sources. Utilizing sunlight via artificial photosynthesis is an interesting possibility. READ MORE

  4. 22. Convergent and Tandem Strategies in Iridium-Catalyzed Asymmetric Hydrogenation of Olefins

    Author : Luca Massaro; Pher Andersson; Antoni Riera; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Enantioconvergent catalysis; asymmetric hydrogenation; iridium catalysis; tandem reaction; mechanistic investigation; Organic Chemistry; organisk kemi;

    Abstract : The work presented in this thesis describes the development of enantioselective methods and their corresponding mechanistic studies to expand the field of catalytic asymmetric hydrogenation. Efficient catalytic systems based on iridium complexes were designed and employed in convergent and tandem strategies to prepare important optically enriched organic compounds. READ MORE

  5. 23. Molecular machinery of a membrane-bound proton pump : Studies of charge transfer reactions in cytochrome c oxidase

    Author : Emelie Svahn; Peter Brzezinski; Ville Kaila; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; membrane protein; respiration; redox reaction; cytochrome aa3; cytochrome c oxidase; Biochemistry; biokemi;

    Abstract : In cellular respiration, electron transfer from the breakdown of foodstuff is coupled to the formation of an electrochemical proton gradient. This is accomplished through proton translocation by respiratory complexes, and the proton gradient is subsequently used e.g. to drive ATP production. READ MORE

  6. 24. Formation and Decomposition of Platinum–Thallium Bond, Kinetics and Mechanism. Structural Characterization of Some Metal Cyanides in the Solid State

    Author : Péter Nagy; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal–metal bond; platinum; thallium; kinetics; mechanism; stopped flow; oxidative addition; cyano complexes; edta; redox reaction; metal cyanides; X–ray diffraction; Raman; NMR; mercury; palladium; nickel; one dimensional wire;

    Abstract : The kinetic and mechanistic features of a new series ofplatinum-thallium cyano compounds containing a direct andunsupported by ligands metal-metal bond have been studied insolution, using standard mix–and–measurespectrophotometric technique and stopped–flow method.These reactions are interpreted as oxidative addition of the cspecies to the square planar Pt(CN)42-complex.

  7. 25. Observability and identifiability of nonlinear systems with applications in biology

    Author : Milena Anguelova; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Observability; identifiability; nonlinear systems; time delay; delay systems; state elimination; metabolism; conservation laws; signalling pathways.; signalling pathways.;

    Abstract : This thesis concerns the properties of observability and identifiability of nonlinear systems. It consists of two parts, the first dealing with systems of ordinary differential equations and the second with delay-differential equations with discrete time delays. READ MORE
