1. Resonant Soft X-Ray Emission Spectroscopy of Vanadium Oxides and Related Compounds
Sammanfattning : This thesis addresses the electronic structure of vanadium and copper oxides using soft X-ray absorption (SXA) spectroscopy and resonant inelastic X-ray scattering (RIXS) at high brightness synchrotron radiation sources. In RIXS incident photons, tuned to the energy of specific absorption resonances, are inelastically scattered leaving behind a low energy valence excitation in the system studied. LÄS MER
2. Synchrotron-based characterization of mechanobiological effects on the nanoscale in musculoskeletal tissues
Sammanfattning : Collagen is the main organic building block of musculoskeletal tissues. Despite collagen being their smallest load bearing unit, these tissues differ significantly in mechanical function and properties. A major factor behind these differences is their hierarchical organization, from the collagen molecule up to the organ scale. LÄS MER
3. Anion redox processes in novel battery cathode materials investigated by soft X-ray spectroscopy
Sammanfattning : This thesis presents experimental investigations of the electronic structure of emerging and novel cathode materials used in lithium- and sodium-ion batteries. The investigated materials include a range of oxide materials containing the elements nickel and manganese. LÄS MER
4. Applications of Soft X-Ray Spectroscopy
Sammanfattning : Soft X-ray emission spectroscopy is an old experimental technique that has seen a strong revival since the advent of new high brilliance soft X-ray sources in the shape of synchrotrons. This thesis covers a range of applications where soft x-ray techniques have been applied. LÄS MER
5. Spontaneous and stimulated X-ray Raman scattering
Sammanfattning : The present thesis is devoted to theoretical studies of resonant X-ray scattering and propagation of strong X-ray pulses. In the first part of the thesis the nuclear dynamics of different molecules is studied using resonant X-ray Raman and resonant Auger scattering techniques. LÄS MER
