1. Synchrotron-based characterization of mechanobiological effects on the nanoscale in musculoskeletal tissues
Abstract : 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. READ MORE

2. Ultrafast spin dynamics at the nanoscale : using coherent X-ray and terahertz radiation
Abstract : The field of ultrafast magnetism is driven by the growing need for faster and more efficient magnetic data storage, which comprises the vast majority of the digital information worldwide. However, after more than two decades of intense research, the understanding of the fundamental physical processes governing the transfer of angular momentum necessary for magnetic switching, is still lacking, partially hampered by the appropriate experimental tools.

3. X-Ray Diagnostics in Combustion - Study of Particle Formation in Flames Using Combined Small- and Wide-Angle X-Ray Scattering
Abstract : In the thesis work, two X-ray scattering techniques, small- and wide-angle X-ray scattering (SAXS and WAXS) were combined to study particle formation in-situ and non-intrusively in ethylene laboratory flames. Combining these two techniques enabled information concerning the size and concentration as well as the subnanometer structure of the nanoparticles within the 1–100 nm range there to be obtained.

4. Multiscale X-ray Characterisation of Cellulose-based Solid Dispersions
Abstract : Cellulose-based solid dispersions are a promising formulation strategy for providing controlled drug release and dissolution enhancement of poorly soluble drugs. These dispersions can from structures on multiple length scales which can have both positive and negative effects on the functional properties of the formulation. READ MORE

5. Bone structure characterisation using neutron scattering techniques
Abstract : Bones have unique mechanical properties that originate from their main constituents: mineral, in the form of hydroxyapatite (HAp) crystals, and collagen type-I. The stiffness of the HAp mineral combined with the flexibility of collagen, and their intricate hierarchical arrangement from the smallest individual building blocks to the organ level, result in a composite tissue with a remarkable ability to withstand complex loading scenarios.
