  1. 1. In Situ Soft X-ray Spectroscopies Applied to Atmospheric Corrosion And Related Systems

    Author : Johan Forsberg; Joseph Nordgren; Laurent Duda; Clemens Heske; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Physics; Fysik;

    Abstract : This thesis concerns the application of various soft x-ray spectroscopic methods (soft x-ray absorption, SXA, and emission, SXE) to complex, non-vacuum compatible systems, including liquids and multi-phase systems. The design, construction, and application of new instrumentation for in situ spectroscopy is described in detail. READ MORE

  2. 2. Resonant Inelastic X-ray Scattering of Rare-Earth and Copper Systems

    Author : Kristina Kvashnina; Joseph Nordgren; Clemens Heske; Uppsala universitet; []
    Keywords : Physics; resonant inelastic X-ray scattering; Fysik;

    Abstract : Rare earths and copper systems were studied using X-ray absorption spectroscopy (XAS) and resonant inelastic X-ray scattering (RIXS). The use of monochromased synchrotron radiation and improved energy resolution for RIXS made possible to obtain valuable information on the electronic structure in 4f, 5f and 3d systems. READ MORE

    Abstract : In spite of their high abundance and importance, aqueous systems are enigmatic on the microscopic scale. In order to obtain information about their geometrical and electronic structure, simple aqueous solutions have been studied experimentally by photo- and Auger electron spectroscopy using the novel liquid micro-jet technique in conjunction with synchrotron radiation.
