6. Molecular Mechanisms Influencing the Performance of Amorphous Formulations for Poorly Water-Soluble Drugs
Sammanfattning : Crystallisation is a concern for amorphous formulation because it compromises the solubility-enhancing benefit gained from amorphisation. Traditionally, amorphous formulation had been designed primarily based on trial-and-error approach. LÄS MER
7. Insights into key processes governing atmospheric aerosol loadings and their interactions with clouds
Sammanfattning : Aerosol particles are ubiquitous in the atmosphere and an essential part of the atmospheric radiation balance regulating the Earth’s temperature. Aerosol-cloud interaction still remains the largest single uncertainty in future climate projections. In addition, aerosols are also responsible for air pollution, causing severe health effects.

8. Flow structures in solid-liquid suspensions in mixing and confined jets
Sammanfattning : This thesis is an investigation of the influence of solid particles on different liquid flow systems. Large-scale periodic fluctuations such as macro instabilities (MI) and particle cloud dynamics in a mixing vessel and confined jets were studied experimentally and compared to numerical results from CFD simulations.

9. Turbulence-droplet interaction modelled by One-Dimensional-Turbulence
Sammanfattning : A stochastic model to study droplet/particle influence on the gas phase using the One-Dimensional-Turbulence model (ODT) is evaluated. To address one of the major problems for multiphase flow simulations, namely computational costs, the dimension-reduced model is used with the goal of predicting certain classes of these flows more efficiently.

10. Flow structures in solid-liquid suspensions in mixing and confined jets
Sammanfattning : This thesis investigates the influence of solid particles on different liquid flow systems.Large-scale periodic fluctuations such as macro instability (MI) phenomena in a mixingvessel and jet flows in a confined jet were experimentally analyzed by means of LDV.
