1. Uranium nitride synthesis by gas/gas reaction of UF6 and NH3
University essay from KTH/FysikAbstract : This thesis project aims to develop an innovative technique for the production of high-purity uranium nitride (UN) through the ammonolysis of fluorides. The desired objective is to perform a controlled gas/gas reaction between uranium hexafluoride (UF6) and ammonia (NH3) at 800°C. READ MORE

2. Experimental studies of radiation damage in uranium nitride
University essay from KTH/FysikAbstract : The effect of proton (H+) irradiation on uranium mononitride (UN) and UN compositefuel with 10 at.% ZrN (UN10at%ZrN) was examined. Protons of 2 MeV with fluences of1E17, 1E18, 1E19 and 1E20 ions/cm2 were accelerated towards the fabricated samples in orderto investigate the evolution of the micro-structure. READ MORE

5. Synthesis of Nanostructured Silicon - Germanium Thermoelectric Materials by Mechanical Alloying
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : 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. READ MORE
