  3. 12. Heat Transfer and Energy Efficiency in Infrared Paper Dryers

    Författare :Magnus Pettersson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; experimental; modelling; electricity; gas; efficiency; energy; drying; dryer; heat transfer; radiation; paper; infrared; IR; coating; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : Infrared (IR) dryers are widely used in the paper industry, mainly in the production of coated paper grades. The thesis deals with various aspects of heat transfer and energy use in infrared heaters and dryers as employed in the paper industry. Both gas-fired and electric IR dryers are considered and compared. LÄS MER

  4. 13. Theoretical modeling of x-ray and vibrational spectroscopies applied to liquid water and surface adsorbates

    Författare :Mathias P. Ljungberg; Lars Pettersson; Shaul Mukamel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water; XAS; XES; IR; Raman; Chemical physics; Kemisk fysik; kemisk fysik; Chemical Physics;

    Sammanfattning : This thesis presents results of theoretical modeling of x-ray and vibrational spectroscopies applied to liquid water and to CO adsorbed on a Ni(100) surface. The Reverse Monte Carlo method is used to search for  water structures that reproduce diffraction, IR/Raman and x-ray absorption by fitting them to experimental data and imposed constraints. LÄS MER

  5. 14. Isotope labeling of proteins for spectroscopic studies

    Författare :Emil Gustavsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Isotope labeling; Proteins; Cell-free protein expression; NMR; IR; Infrared;

    Sammanfattning : Protein structural dynamics have been closely tied to the molecular mechanisms controlling for example enzyme activities. In my work, I have mainly studied the bacteriophytochrome from Deinococcus radiodurans. LÄS MER

  7. 15. Spectral Analysis of Neutron Capture Elements in the Laboratory and Stars

    Författare :Martin Lundqvist; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cosmic chemistry; Astronomy; space research; Atom- och molekylärfysik; Atomic and molecular physics; Astronomi; Sm; Hf; Os; Ir; Neutron capture processes; rymdvetenskap; kosmisk kemi; cool stars; Spectroscopy; atomic data;

    Sammanfattning : The pedigree of the elements heavier than iron is a vital question in the history and evolution of our galaxy. The elements up to and including those of the iron group are produced mainly through fusion processes within stars, giving the stars their energy. LÄS MER
