1. Fabrication and Characterization of Bulk Nanostructured Cobalt Antimonide based Skutterudites Materials for Thermoelectric Applications.
Master-uppsats, KTH/Material- och nanofysikSammanfattning : The increasing price of oil, global warming and rapid industrial growth has drawn much attention to renewable energy technologies over the last few decades. The total energy consumption is estimated to increase 1.4% per year globally. About 90% of this energy supply is generated through fossil fuel combustion with a typical efficiency of 30-40%. LÄS MER
2. Fabrication and Characterization of UN-USix Nuclear Fuel
Master-uppsats, KTH/ReaktorfysikSammanfattning : In this thesis, UN-U3Si2 nuclear fuel was fabricated using spark plasma sintering and characterized to analyze the microstructure and crystal structure of the resulting pellets. This work was done in collaboration with accident tolerant fuel research, an effort which aims at developing nuclear fuel with superior safety and performance compared to currently used oxide fuels.

3. Synthesis of Nanostructured Silicon - Germanium Thermoelectric Materials by Mechanical Alloying
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : Silicon-germanium (SiGe) thermoelectric material is especially suited in power generation operating above 700 °C to 1000 °C to convert heat into electricity. Traditional bulk SiGe alloy thermoelectric materials has the value of dimensionless thermoelectric figure of merit (ZT) at maximum about 0.93 at 900 °C. LÄS MER

5. Manufacturing methods for (U-Zr)N-fuels
Master-uppsats, KTH/FysikSammanfattning : In this work a manufacturing method for UN, ZrN and (U,Zr)N pellets was established at the nuclear fuel laboratory at KTH Stockholm/Sweden, which consists of the production of nitride powders and their sintering into pellets by spark plasma sintering. The nitride powders were produced by the hydriding-nitriding route using pure metal as starting material. LÄS MER
