26. Continuum modelling of particle flows in high shear granulation
Sammanfattning : High shear granulation is an important process in the pharmaceutical industry. The aim of the process is to produce granules with specific properties, like size and hardness, from powder mixtures. The properties of the granules are determined by the flow field in the mixer. LÄS MER
27. Transition Metal Catalysis for Selective Synthesis and Sustainable Chemistry
Sammanfattning : This thesis discusses the preparation and use of transition-metal catalysts for selective organic chemical reactions. Specifically, two different matters have been studied; the asymmetric hydrogenation of carbon-carbon double bonds using N,P-ligated iridium catalysts and the metal-catalyzed transfer of small molecules from biomass to synthetic intermediates.

29. Palladium(II)-Catalyzed Oxidative Carbocyclization/Functionalization of Allenynes
Sammanfattning : The selective formation of carbon-carbon bonds constitutes a key transformation in organic synthesis with useful applications in pharmaceutical or material industry. A particularly versatile tool for carbon-carbon as well as carbon-heteroatom bond formation is palladium catalysis, which allows for mild and selective routes even towards complex structures. LÄS MER
30. Self assembly of surfactants and polyelectrolytes in solution and at interfaces
Sammanfattning : This thesis focuses on the study of the interactions between polyelectrolytes and surfactants in aqueous solutions and at interfaces, as well as on the structural changes these molecules undergo due to that interaction. Small–angle neutron scattering, dynamic, and static light scattering were the main techniques used to investigate the interactions in bulk. LÄS MER
