  1. 21. Synchrotron radiation induced fluorescence spectroscopy of gas phase molecules

    Författare :Jesús Álvarez Ruiz; Elisabeth Rachlew; J. E. Rubensson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; molecular spectroscopy; photon induced fluorescence; synchrotron radiation; superexcited states; Fysik; Physics; Fysik;

    Sammanfattning : A new experimental set-up for gas phase fluorescence studies using synchrotron radiation has been designed and constructed to perform simultaneously total and dispersed fluorescence measurements. Neutral photodissociation of CO has been investigated after excitation with 19-26 eV photons. LÄS MER

  3. 22. Laser Scanning Multiphoton Microscopy – Focusing on Fluorescence Correlation Spectroscopy and Fluorescence Lifetime Imaging for Biomedical Applications

    Författare :Jeemol James; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser scanning multiphoton microscopy; intrinsic cellular fluorophores.; fluorescence correlation spectroscopy; fluorescence lifetime imaging; melanoma metastasis;

    Sammanfattning : Laser scanning multiphoton microscopy (MPM) is considered as a non-invasive technology for three-dimensional imaging of complex biological tissues. The quantitative potential of the MPM is not investigated as much as qualitative imaging. LÄS MER

  4. 23. New applications of fluorescence spectroscopy for monitoring drinking water disinfection and distribution

    Författare :Masoumeh Heibati; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dissolved organic matter; UV disinfection; Fluorescence spectroscopy; drinking water; distribution network;

    Sammanfattning : The task of providing safe drinking water requires proper monitoring of water quality and treatment performance from source to tap. Accordingly, the demand for online monitoring is increasing both at treatment plants and within distribution networks. LÄS MER

  5. 24. The effect of sequence truncation and amino-acid substitutions on the biophysical properties of protein S and calbindin D9k

    Författare :Karin Julenius; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surface plasmon resonance; fluorescence spectroscopy; circular dichroism spectroscopy; NMR spectroscopy; hydrophobic effect; protein stability; dimerization; cooperativity; calcium binding; EGF-module; EF-hand; calbindin D9k; protein S; synthet; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Protein S is a modular protein and a cofactor in the protein C anticoagulant system. It consists of a Gla-module, a thrombin-sensitive loop, four EGF-modules and a SHBG-like module. LÄS MER

  7. 25. Laser-Induced Emission Techniques for Concentration and Temperature Probing in Combustion

    Författare :Gustaf Särner; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermographic phosphor; phosphor; phosphorescence; Laser Combustion Diagnostics; Laser-Spectroscopy; LIF; spectroscopy; Thermometry; LIP; Laser-Induced Fluorescence;

    Sammanfattning : The work in this thesis is aimed at the development of temperature and gas concentration measurement techniques in laser diagnostics for use in combustion research. The techniques are developed as tools for the combustion community to meet future demands on combustion efficiency and legislation of exhaust gases. LÄS MER
