  1. 1. Extraction Properties of some Nitrogen-Containing Extractants and Determination of Nitrate Complex Formation for Lanthanides and Selected Actinides Using Solvent Extraction

    Författare :Sofie Andersson; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actinides; solvent extraction; separation; lanthanides; nitrate complex formation;

    Sammanfattning : Partitioning and transmutation of spent nuclear fuel will reduce the amount of waste and its radiotoxicity in a long-term perspective. At the same time the energy content of the spent nuclear fuel can be used more efficiently by recycling of uranium and plutonium and by using energy from the transmutation reactor. LÄS MER

  2. 2. Mononuclear Ruthenium Complexes that Catalyze Water to Dioxgen Oxidation

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Lianpeng Tong; KTH.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ruthenium complex; Homogeneous catalysis; Water oxidation; O2 evolution; anionic ligand; Molecular catalyst; Electrocatalysis; Kinetics; Artificial photosynthesis; Light-driven; Immobilization of catalyst;

    Sammanfattning : The theme of this thesis is the development of mononuclear Ru-based complexes that are capable of catalyzing the water oxidation (or O2-evolving) reaction, e.g. 2 H2O → O2 + 4 H+ + 4 e−. Several families of mononuclear Ru water oxidation catalysts were designed and prepared. LÄS MER

  3. 3. The significance of sexuality and cyst formation in the life-cycles of four marine dinoflagellate species

    Detta är en avhandling från Lund University

    Författare :Rosa Figueroa; Lunds universitet.; Lund University.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cyst; Hydrobiology; akvatisk ekologi; marine biology; aquatic ecology; limnology; sexuality.; meiosis; Lingulodinium polyedrum; life-cyle; limnologi; Marinbiologi; Gymnodinium nolleri; Gymnodinium catenatum; Alexandrium catenella; dinoflagellates;

    Sammanfattning : Sexuality and cyst formation were studied in the marine dinoflagellate species Gymnodinium catenatum Graham, Gymnodinium nolleri Ellegaard ? Moestrup, Alexandrium catenella (Whedon et Kofoid) Balech, and Lingulodinium polyedrum (Stein) Dodge. The study included the morphological characterization of sexual stages and processes, the time and description of meiosis, the study of the length and regulation of the mandatory dormancy period of resting cysts, and the relationships among parental strains and cyst progeny at phenotypic and molecular levels.

  4. 4. Modelling of molybdopterin-dependent enzymes

    Detta är en avhandling från Anders Thapper, Inorganic Chemistry 1, Chemical Center, Lund University

    Författare :Anders Thapper; Lunds universitet.; Lund University.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; enzymes; transition state; intermediate; mechanism; molybdopterin; density functional theory; model systems; oxygen atom transfer; molybdenum; tungsten; Oorganisk kemi; Chemistry; Kemi;

    Sammanfattning : Popular Abstract in Swedish Molybden ingår som en viktig del i två typer av biologiska system - dels i nitrogenas, som fixerar kvävgas ur atmosfären, och dels i de enkärniga molybdenenzymerna. De senare är enzymer som innehåller endast en molybdenatom i sina aktiva säten. LÄS MER

  5. 5. Structural studies on aerobic and anaerobic respiratory complexes

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Susanna Törnroth; Uppsala universitet.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; biokemi; Biochemistry;

    Sammanfattning : All respiratory pathways, whether aerobic or anaerobic, are based on formation of an electrochemical proton gradient called proton motive force (pmf) that drives ATP formation. Membrane-bound respiratory complexes translocate protons across the membrane from a region of low [H+] and negative electrical potential to a region of high [H+] and positive electrical potential.
