  4. 2. 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

  5. 3. 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 : NATURVETENSKAP; NATURAL SCIENCES; 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

  6. 4. 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

  7. 5. Ordering in Crystalline Short-Chain Polymer Electrolytes

    Author : Anti Liivat; Joseph Nordgren; Josh Thomas; Daniel Brandell; David Brown; Uppsala universitet; []
    Keywords : Atomic and molecular physics; polymer electrolytes; molecular dynamics; ionic conductivity; crystalline ordering; polymer chain length; smectic; nematic; Atom- och molekylfysik;

    Abstract : Polymer electrolytes are the most obvious candidates for safe "all-solid" Li-ion batteries and other electrochemical devices. However, they still have relatively poor ionic conductivities, which limits their wider adoption in commercial applications. READ MORE
