1. Time-Resolved Photoemission Electron Microscopy: Development and Applications
Sammanfattning : Time-resolved photoemission electron microscopy (TR-PEEM) belongs to a class of experimental techniquescombining the spatial resolution of electron-based microscopy with the time resolution of ultrafast opticalspectroscopy. This combination provides insight into fundamental processes on the nanometer spatial andfemto/picosecond time scale, such as charge carrier transport in semiconductors or collective excitations ofconduction band electrons at metal surfaces.

2. Growth and Characterization of Tandem-Junction Photovoltaic Nanowires
Sammanfattning : In order to satisfy the growing energy needs of our planet’s population, and at the same time mitigate global warming, sustainable energy sources such as solar energy are indispensable. In addition to conventional silicon-based solar cells, nanotechnology offers interesting approaches for complementary applications. LÄS MER
3. Solar receiver development for gas-turbine based solar dish systems
Sammanfattning : Small-scale concentrating solar power plants such as micro gas-turbine based solar dish systems have the potential to harness solar energy in an effective way and supply electricity to customers in remote areas. In such systems, the solar receiver transfers the power of concentrated solar radiation to the working fluid of the power conversion cycle. LÄS MER
4. Some Investigations into the Class of Exponential Power Distributions
Sammanfattning : In this thesis, methods are developed relating to the exponential power class of distributions.Paper I considers Bayesian linear mixed models where the usual normality assumption is replaced by the multivariate exponential power distribution. Particular focus lies on Bayesian testing of the fixed effects. LÄS MER
5. Lipid-based liquid crystals as drug delivery vehicles for antimicrobial peptides
Sammanfattning : The development of antimicrobial resistance is a great challenge within health sectors worldwide. Thus, demand for new, efficient treatments is urgent in order to treat various bacterial infections. Antimicrobial peptides (AMPs) are a group of antibiotics that have gained more and more attraction in the past decade. LÄS MER
