16. Numerical modelling of fluid flow and particle transport in rough rock fracture during shear
Abstract : The effects of different shearing processes and sample sizes on the fluid flow anisotropy and its impact on particle transport process in rough rock fractures are significant factors that need to be considered in the performance and safety assessments of underground nuclear waste repositories. The subjects, however, have not been adequately investigated previously in either laboratory experiments or numerical modeling. READ MORE

17. Structural Studies of Large dsDNA Viruses using Single Particle Methods
Abstract : Structural studies of large biological assemblies pose a unique problem due to their size, complexity and heterogeneity. Conventional methods like x-ray crystallography, NMR, etc. are limited in their ability to address these issues. To overcome some of these limitations, single particle methods were used. READ MORE

18. Operando Single Particle Catalysis - Combining a Nanoreactor and Plasmonic Nanospectroscopy
Abstract : Heterogeneous catalysis is an important cornerstone of modern society with strong ties to the development of sustainable sources of energy and products. Catalysts are typically realized as supported metal nanoparticles that offer active sites that can accelerate chemical reactions by providing energetically more favorable reaction paths. READ MORE

19. Transition in Particle-laden Flows
Abstract : This thesis presents the study of laminar to turbulent transition of particle laden flows. When a flow becomes turbulent, the drag increases one order of magnitude compared to a laminar flow, therefore, much research is devoted to understand and influence the transition. READ MORE

20. Heat Transfer in Circulating Fluidized Bed Boilers
Abstract : Heat transfer to single particles in the transport zone of circulating fluidized beds and heat transfer to membrane tube walls have been investigated. The heat transfer coefficient to spheres in the transport zone of a circulating fluidized bed boiler has been measured with dark and light calorimeters. READ MORE
