1. On Surface Characteristics and Microstructural Development of Soft Magnetic Composite Powder and Components
Sammanfattning : Soft Magnetic Composite (SMC) products manufactured by traditional Powder Metallurgical (PM) techniques, are strong candidate materials for electromagnetic applications. Their advantages are based on cost and energy efficient production methods, shape complexity realization and uniquely uniform and isotropic three dimensional (3D) magnetic properties. LÄS MER
2. Magnetic orientation in migratory birds
Sammanfattning : My thesis focuses on magnetic orientation in migratory birds, i.e. how they can perceive information from the Earth’s magnetic field and use it for orientation. LÄS MER
3. Magnetic Nanoparticle Based Biosensors for Pathogen Detection and Cancer Diagnostics
Sammanfattning : This thesis describes several magnetic nanoparticle (MNP)-based biosensing strategies which take advantage of different magnetic sensors, molecular tools and nanotechnologies. Proposed biosensors can be classified into three groups, i.e., immunoassay-based, molecular amplification-based, and nanoparticle assembly-based. LÄS MER
4. Testing and Modelling of Electrical Traction Machines : Performance Characterisation with Measurements from Transient Operation
Sammanfattning : This thesis presents methods to derive and model the performance characteristics of interior permanent magnet machines – a machine type which is commonly used for propulsion of electrical vehicles. The thesis divides the performance characteristics into three subcategories: The electromagnetic properties, the loss profile and the thermal behaviour of the machines. LÄS MER
5. Application of magnetic nanoparticles and reactive filter materials for wastewater treatment
Sammanfattning : Lately sewage wastewater treatment processes (WWTP) are facing challenges due to strict regulations in quality of effluent standards and waste production. The reuse of wastewater treatment effluents is rapidly gaining attention as a means of achieving sustainable water supply. Therefore, new methods are required to achieve an efficient WWTP. LÄS MER
