1. Regioselective Heck Coupling Reactions : Focus on Green Chemistry
Abstract : Carbon-carbon bond formation reactions are among the most important processes in chemistry, as they represent key steps in the synthesis of more complex molecules from simple precursors. This thesis describes mainly the development of novel regioselective applications of the mild and versatile palladium-catalyzed carbon-carbon coupling method, commonly known as the Heck reaction.

2. Fluxes and Mixing Processes in the Marine Atmospheric Boundary Layer
Abstract : Atmospheric models are strongly dependent on the turbulent exchange of momentum, sensible heat and moisture (latent heat) at the surface. Oceans cover about 70% of the Earth’s surface and understanding the processes that control air-sea exchange is of great importance in order to predict weather and climate. READ MORE

3. Radio Frequency Systems for NMR Imaging: Coil Development and Studies of Non-Thermal Biological Effects
Abstract : This thesis concerns both design and optimization of NMR imaging systems and studies on non-thermal biological effects of electromagnetic fields. These two research fields are linked together by the fact that humans are subject to static and pulsed magnetic fields as well as to magnetic radio frequency fields (RF) during an NMR imaging investigation.

4. Reduced Order Modeling and Substructuring : Applications in Nonlinear Structural Dynamics
Abstract : A structural design process typically involves various load cases for which a sufficient load-bearing capacity must be demonstrated. In addition to static load cases, a verification of dynamic loads, such as blast and impact loading, may be required. READ MORE

5. Predicting Xenon Oscillations in PWRs using Intrusive Reduced Order Modelling
Abstract : The increasing presence of intermittent energy sources in the Swedish electricity grid necessitates a transition of Swedish nuclear reactors from constant base load operation to load-following mode. However, such changes in power can induce xenon oscillations, a phenomenon that poses operational challenges and the risk of fuel damage. READ MORE
