  1. 1. Atmospheric Chemistry of Volatile Organic Compounds: Oxidation Products, Mechanisms and Secondary Organic Aerosol Formation

    Detta är en avhandling från Göteborgs universitet

    Författare :Julia Hammes; Göteborgs universitet.; Gothenburg University.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SOA; VOC; anthropogenic; biogenic; FIGAERO; CIMS; HOMs; ELVOCs; atmospheric oxidation; chemical mechanism; NOx; limonene; a-pinene; TMB; ozone; nitrate; OH; radical chemistry; RO2; G-FROST; GO:PAM;

    Sammanfattning : The results from this work are a piece in understanding the complex puzzle of atmospheric aerosol formation. Secondary organic aerosol (SOA) formed by the oxidation of volatile organic compounds (VOC) in the atmosphere is a key component of air pollution with a strong negative impact on human health and influence on climate, but its formation is poorly understood.

  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; Lund University.; Lunds universitet.; [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; Lund University.; Lunds universitet.; [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 : The thesis deals with models for molybdopterin-dependent enzymes. Several model systems containing molybdenum or tungsten have been prepared and characterised, and their reactivity with oxygen atom acceptors and donors have been investigated. 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.
