  1. 1. Human Metabolism and Ecological Transfer of Radioactive Caesium

    Författare :Christopher Rääf; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; committed effective dose; aggregate transfer; ecological half-time; equivalent biological half-time; urianry excretion; radiocaesium; body burden; Environmental health; Miljömedicin; creatinine-normalisation; potassium-normalisation;

    Sammanfattning : The whole-body content of radiocaesium was measured in a South-Swedish urban group of people residing in the city of Lund (55.7°N, 13.2°E) between 1960 and 1994. LÄS MER

  3. 2. Exciton coupling and energy transfer in perylene-based systems

    Författare :Alexei Cravcenco; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; Photophysics; Energy transfer; FRET; Perylene; J-aggregate;

    Sammanfattning : Understanding the nature of photoinduced processes in organic molecules is essential for the design and synthesis of compounds with desired photochemical properties. This dissertation aims for gaining knowledge and mechanistic understanding of energy transfer in perylene-based systems. LÄS MER

  4. 3. Melanosome transfer, photoreception and toxicity assays in melanophores

    Författare :Daniel Hedberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; colour change; melanophores; melanosome; intracellular transport; pigment transfer; photoreception; toxicity assay; Roundup; glyphosate;

    Sammanfattning : Many animals such as fish and frogs have developed the ability to change colour of their skin to adapt to the environment or to signal to other individuals. This ability is due to specialised skin cells called melanophores. LÄS MER

  5. 4. Quantum Coherence for Light Harvesting

    Författare :David Palecek; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coherent two-dimensional spectroscopy; Quantum coherence; Light harvesting; Photosynthetic reaction center; Energy transfer;

    Sammanfattning : Almost all life on Earth depends on the products of photosynthesis — the biochemical process whereby solar energy is stored as chemical-rich compounds. The energy of captured photons is transferred through a network of pigment-protein complexes towards the reaction center. LÄS MER

  7. 5. Probing the Effects of Conformation on the Photophysics of Conjugated Porphyrin Oligomers

    Författare :Melina Gilbert Gatty; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electron transfer; conformational analysis; conjugated porphyrin oligomers;

    Sammanfattning : Controlling the conformational heterogeneity of molecular systems is fundamental to envisage future applications of these systems, such as in solar cells or molecular devices to name a few. The work presented in this Thesis investigates the effects of conformational flexibility on the photophysical properties of a series of conjugated porphyrin oligomers Pn (n = 1-4, 6, 8). LÄS MER
