1. Chemical Properties of Oxidized Silver - A Density Functional Theory Study
Sammanfattning : .... LÄS MER
2. Spectral Mammography with X-Ray Optics and a Photon-Counting Detector
Sammanfattning : Early detection is vital to successfully treating breast cancer, and mammography screening is the most efficient and wide-spread method to reach this goal. Imaging low-contrast targets, while minimizing the radiation exposure to a large population is, however, a major challenge. LÄS MER
3. Nanostructured carbon materials prepared by hole-mask colloidal lithography
Sammanfattning : Research and development of nanofabrication methods can be motivated both formanufacturing of commercially available products like micro electronic componentsand for development of model systems for fundamental and applied science. Thefabrication process developed during this work, hole-mask colloidal lithography(HCL), is primarily oriented towards the latter two, specifically for research in thefields of catalysis, nanoparticle plasmons, and bio- and fundamental physics.

4. Nanostructures of Graphite and Amorphous Carbon - Fabrication and Properties
Sammanfattning : Nanoscience is a well-established research area, which concerns properties and fabrication of objects with typical dimensions on the 1-100 nanometer length scale. A central issue has been the development of techniques for fabrication and characterization of nanometer sized objects, which have contributed considerably to progress in both practical applications and fundamental research.

5. Kinetic Measurements Using Nanoplasmonic Sensing
Sammanfattning : In this thesis the nanoplasmonic sensing technique was used to study kinetics of (i) the oxidation of Al nanoparticles in air and water and (ii) the solid-liquid phase transition in Sn nanoparticles. The nanoplasmonic sensing technique detects changes of the localized surface plasmon resonance (LSPR) in metal nanoparticles. LÄS MER
