1. Uranium nitride synthesis by gas/gas reaction of UF6 and NH3
Master-uppsats, KTH/FysikSammanfattning : 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. LÄS MER
2. Experimental studies of radiation damage in uranium nitride
Master-uppsats, KTH/FysikSammanfattning : 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. LÄS MER
3. Fabrication and characterization of GaAsxP1-x single junction solar cell on Si for III-V/Si tandem solar cell
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Silicon based solar cells have been used as photovoltaic devices for decades due to reasonable cost and environment- friendly nature of silicon. But the conversion efficiency of silicon solar cell is limited; for instance, the maximum conversion efficiency of a crystalline silicon solar cell available in the market developed by Kaneka Corporation is 26 % [1].

4. Theoretical investigation of α-iron chromium carbide (α-Fe/Cr7C3) interfaces
Master-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)Sammanfattning : This master thesis presents a theoretical investigation of the energy and stability of interfaces in iron-carbide compounds, specifically focusing on the α-Fe/Cr7C3 system. The study aims to fill the gap in knowledge regarding the surface energetics of these interfaces using Density Functional Theory (DFT). LÄS MER
5. Study of Reverse Water Gas Shift reaction using bimetallic catalysts on active supports : The case of unpromoted and K-promoted FeCu/CeO2
Master-uppsats, KTH/KemiteknikSammanfattning : Reverse Water Gas Shift Reaction (RWGS) är en attraktiv lösning för CO2-använding och minskning av utsläppen i atmosfären. Denna reaktion begränsas av termodynamiken och det finns problem med storskalig tillämpning. För att förbättra genomförandet av processen krävs utveckling av en effektiv katalysator. LÄS MER
