  1. 1. Heat Transfer and Energy Efficiency in Infrared Paper Dryers

    University dissertation from Chemical Engineering, Lund University

    Author : Magnus Pettersson; Lund University.; Lunds universitet.; [1999]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Mathias P. Ljungberg; Stockholms universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; water; XAS; XES; IR; Raman; NATURAL SCIENCES Physics Atomic and molecular physics Chemical physics; NATURVETENSKAP Fysik Atom- och molekylfysik Kemisk fysik; Chemical Physics; kemisk fysik;

    Abstract : 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.

  3. 3. Isotope labeling of proteins for spectroscopic studies

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Emil Gustavsson; Göteborgs universitet.; Gothenburg University.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Isotope labeling; Proteins; Cell-free protein expression; NMR; IR; Infrared;

    Abstract : 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. READ MORE

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

    University dissertation from Lund Observatory, Lund University

    Author : Martin Lundqvist; Lund University.; Lunds universitet.; [2006]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. Beyond average crystal structures: understanding extended and local environments in proton-conducting Sc-substituted BaTiO3 perovskites

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Nico Torino; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; proton conducting oxide; IR; thermogravimetry; perovskite; neutron scattering; Raman; Reverse Monte Carlo; ordering; BaTiO3;

    Abstract : Proton conducting ceramics are very promising for applications concerned with energy sourcing with cleaner, safer, more abundant and cheaper alternatives to fossil fuels. These materials are still in development and advances in the field depend on a better understanding of the role of defects, their identification and location in the host framework, and the assessment of their short- and long-range dynamics and kinetics.
