16. Permanent Magnet Machines with Air Gap Windings and Integrated Teeth Windings
Sammanfattning : The thesis deals with axial and radial flux permanent magnet machines with air gap windings and an integrated teeth winding. The aim is to develop a machine that produces a high torque per unit volume with as low losses as possible. LÄS MER
17. Rechargeable Aqueous Batteries Based on Available Resources : Investigation and Development towards Efficient Battery Performance
Sammanfattning : Batteries employing water based electrolytes enable extremely low manufacturing costs and are inherently safer than Li-ion batteries. Batteries based on zinc, manganese dioxide, iron, and air have high energy relevancy, are not resource restricted, and can contribute to large scale energy storage solutions. LÄS MER
18. Settling Mechanisms of Valuable Metal Droplets in Iron Silicate Slag
Sammanfattning : A significant source of copper losses from pyrometallurgical copper extraction is attributed to dissolved and entrained copper in discarded slag. Entrained copper can be recovered via pyrometallurgical slag cleaning in a settling furnace where the droplets settle under gravity. LÄS MER
19. Studies for the Low Emittance MAX-IV Storage Rings
Sammanfattning : This thesis discusses the feasibility of a low emittance lattice proposed for the MAX-IV storage rings. The MAX-IV facility will have two storage rings that are identical but operated at two different energies, 1.5 GeV for soft X-ray and 3 GeV for hard X-ray production. LÄS MER
20. Stepping into Catalysis : Kinetic and Mechanistic Investigations of Photo- and Electrocatalytic Hydrogen Production with Natural and Synthetic Molecular Catalysts
Sammanfattning : In light of its rapidly growing energy demand, human society has an urgent need to become much more strongly reliant on renewable and sustainable energy carriers. Molecular hydrogen made from water with solar energy could provide an ideal case. LÄS MER
