1. Iron Losses in Electrical Machines - Influence of Material Properties, Manufacturing Processes, and Inverter Operation
Sammanfattning : As the major electricity consumer, electrical machines play a key role for global energy savings. Machine manufacturers put considerable efforts into the development of more efficient electrical machines for loss reduction and higher power density achievements. LÄS MER
2. Fischer-Tropsch synthesis from bio-syngas models over cobalt and cobalt-iron alumina supported catalysts
Sammanfattning : Fischer-Tropsch (FT) synthesis is a process in which synthesis gas (syngas), a mixture of H2 and CO, is converted into long chain hydrocarbons mainly over Co- or Fe-based catalysts. The FT synthesis requires an H2/CO molar ratio (usage ratio) of approximately 2.1 above the catalyst surface. If the inlet syngas H2/CO ratio is less than 2. LÄS MER
3. Partial methane oxidation from electronic structure calculations
Sammanfattning : Investigating catalytic reactions with computational methods is a powerful approach to understand fundamental aspects of catalytic reactions and find ways to guide catalytic design. Partial methane oxidation is one example of a reaction with intriguing challenges, where a detailed atomistic approach may help to unravel the bottlenecks of this, as of yet, inefficient reaction.
