11. Characterisation of Muko iron ores (Uganda( for defferent routes of iron production
Sammanfattning : Iron and its products, especially the various forms of steel, have been and still are a vital material in many sectors of life. It is utilized in many industrial activities ranging from production of heavy duty mechanical equipment to light electrical appliances and home appliances. With the world‟s iron ore consumption estimated to stand at 1. LÄS MER
12. Sustainable Aluminum and Iron Production
Sammanfattning : Aluminium recycling requires 95% less energy than primary production with no loss of quality. The Black Dross (BD) produced during secondary aluminium production contains high amounts of water-soluble compounds, therefore it is considered as a toxic waste. LÄS MER
13. Variance Reduction in Analytical Chemistry : New Numerical Methods in Chemometrics and Molecular Simulation
Sammanfattning : This thesis is based on five papers addressing variance reduction in different ways. The papers have in common that they all present new numerical methods. LÄS MER
14. Towards Rational Design of Asymmetric Catalyst for Organometallic and Organocatalytic Reactions
Sammanfattning : This thesis deals with synthetically modified chiral molecules and their application in asymmetric catalysis. The first part of the thesis describes the use of commercially available chiral diamine ligands in the iridium catalyzed transfer hydrogenation of aromatic ketones. LÄS MER
15. Transition delay in boundary-layer flows via reactive control
Sammanfattning : Transition delay in boundary-layer flows is achieved via reactive control of flow instabilities, i.e. Tollmien-Schlichting (TS) waves. Adaptive and model-based control techniques are investigated by means of direct numerical simulations (DNS) and experiments. LÄS MER
