  1. 1. Photophysics and Photochemistry of Iron Carbene Complexes

    Författare :Linnea Lindh; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tidsupplöst spektroskopi; täthetsfunktionalteori; järn-komplex; färgämne; grätzelsolcell; fotokatalys; elektronöverföringsreaktion; time-resolved spectroscopy; density functional theory; earth-abundant; iron-complex; photosensitiser; dye-sensitised solar cell; photocatalysis; electron transfer;

    Sammanfattning : Nature captures sunlight via light-absorbing molecules.Similarly, photosensitisers are used in applications of solar cells and artificial photosynthesis to absorb sunlight, and transfer the excited electron. LÄS MER

  3. 2. Spectroscopic techniques for photodynamic therapy dosimetry

    Författare :Ann Johansson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; diffuse light spectroscopy; photodynamic therapy; biomedical optics; Atom- och molekylärfysik;

    Sammanfattning : Photodynamic therapy (PDT) as a cancer treatment modality relies on the simultaneous presence of three components; light, photosensitiser and oxygen. Once excited by the light, the photosensitiser can interact with oxygen, leading to the formation of toxic oxygen species. LÄS MER

  4. 3. Development and evaluation of optical techniques for tumour detection

    Författare :Charlotta Lindquist; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Different optical methods for tumour detection have been studied. Interference between photon density waves has been examined with the aim of investigating the potential of this technique for optical transillumination diagnostics. LÄS MER

  5. 4. Development of metal complexes for water oxidation

    Författare :Bao-Lin Lee; Sascha Tiede; Stockholms universitet; []
    Nyckelord :;

    Sammanfattning : In the course of developing a water oxidation catalyst, five metal complexes have been synthesised, characterised and studied for catalytic activity. Three of them are dinuclear complexes (Ru, Co and Cu) of 2,6-bis[(2-hydroxybenzyl)-(2-pyridylmethyl)aminomethyl]-4-methylphenol (H3bbpmp). LÄS MER

  7. 5. Development of metal complexes for water oxidation

    Författare :Bao-Lin Lee; Björn Åkermark; Xiaodong Zou; Antoni Llobet; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organisk kemi; Organic Chemistry;

    Sammanfattning : In an artificial version of photosynthesis, sunlight and water are used to produce fuels. Our research focuses on the bottleneck in this process, the photooxidation of water. In the course of developing a water oxidation catalyst, a number of metal complexes have been synthesised, characterised, and studied for catalytic activity. LÄS MER
