  2. 11. Soft X-ray Emission Spectroscopy of Liquids and Lithium Battery Materials

    Author : Andreas Augustsson; Joseph Nordgren; Jinghua Guo; Kevin Smith; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Soft X-ray emission; resonant inelastic X-ray scattering; lithium battery; electronic structure; liquid water; Atom- och molekylfysik; Atomic and molecular physics; Atom- och molekylfysik;

    Abstract : Lithium ion insertion into electrode materials is commonly used in rechargeable battery technology. The insertion implies changes in both the crystal structure and the electronic structure of the electrode material. READ MORE

  4. 12. 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 : Unconventional superconductivity is one of the many fascinating research areas of condensed matter physics. Understanding the superconducting pairing mechanism and its connection with other competing states remains unclear. READ MORE

  6. 14. Ab initio simulations of core level spectra : Towards an atomistic understanding of the dye-sensitized solar cell

    Author : Ida Josefsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multiconfigurational quantum chemistry; CASSCF calculations; core-level spectroscopy; x-ray photoelectron spectroscopy; x-ray absorption; resonant x-ray scattering; dye solar cells; transition metals; kemisk fysik; Chemical Physics;

    Abstract : The main focus of this thesis is ab initio modeling of core level spectra with a high-level quantum chemical description both of the chemical interactions and of local atomic multiplet effects. In particular, the combination of calculations and synchrotron-based core-level spectroscopy aims at understanding the local structure of the electronic valence in transition metal complexes, and the details of the solvation mechanisms of electrolyte solutions, systems relevant for the dye-sensitized solar cell.
