    Abstract : Popular Abstract in Swedish De flesta svenskar har nog upplevt hur skönt det kan värma i solen en klar vinterdag, trots att termometern visar minusgrader. Eller hur kallt det känns på ryggen en sommarkväll fastän man så sitter så nära en eld att det nästan bränns. 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

    Abstract : Popular Abstract in Swedish Grundämnena tyngre än järns ursprung är en vital fråga inom historien on och evolutionen av vår galax. Grundämnena upp till och med järngruppen produceras huvudsakligen genom fusion inne i stjärnor som ger dem deras energi. READ MORE

  5. 5. The chemical nature of CO2 adsorption in zeolite A

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

    Author : Przemyslaw Rzepka; Stockholms universitet.; [2019]

    Abstract : The climate changes are accelerated by increasing levels of carbon dioxide in the atmosphere connected to the fossil-fuel-based energy system. Substantial reforms of the system are needed immediately and could include the implementation of carbon capture and storage (CCS) technologies. READ MORE
