1. 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
2. Understanding the correlation between molecular structure of chilled dairy creams and the risk of environmental stress cracking in Tetra Pak® carton packages
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : Multilayer food packaging are lined with an inner layer of plastic and has excellent barrier properties. However, plastics lose their mechanical properties after being exposed to certain conditions; the combination of factors generates failures in the material such as the appearance of cracks, this phenomenon is known as environmental stress cracking (ESC).

3. Broad ion beam cross-sectioning, microscopy, and image analysis of battery electrode morphology
Master-uppsats, Lunds universitet/Industriell ProduktionSammanfattning : Lithium-ion batteries (LiB) are witnessing an increasing demand for electric vehicles. It provides a sustainable energy storage solution that is more efficient and ecofriendly than the fossil fuels. LÄS MER
4. Investigating Particle Cracking in Single- and Polycrystalline Nickel-Rich Cathodes using In Situ Impedance Spectroscopy
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/StrukturkemiSammanfattning : State-of-the-art Li-ion cathode materials are based on LiMO2 (M=Ni, Mn, Co) layered transition metal oxides (denoted NMC) with Ni-rich composition because of their high specific capacity. Yet, these materials suffer from poor capacity retention due to crack formation during de-/lithiation cycling. LÄS MER
5. Erosion Behaviour of Thermal Barrier Coatings
Master-uppsats, Linköpings universitet/KonstruktionsmaterialSammanfattning : Thermal barrier coatings (TBCs) are advanced material systems used in the hot sections of gas turbines. The TBCs are designed to provide insulation against hot gases by a ceramic top coat and to provide oxidation and corrosion resistance by a metallic bond coat. LÄS MER
