1. Characterisation of Non-metallic Inclusions in Special Steels using Electrolytic Extraction
Master-uppsats, KTH/MaterialvetenskapSammanfattning : When producing high strength special steels strict requirements are in place to assure the quality of the final product, both in terms of harmful elements and the content of non-metallic inclusions (NMI). Achieving cleanliness is a gradual process where all the steps of the production process are inter- connected, meaning that it is crucial to know the influence of each step in order to assure the contents of the final product.

2. Micromechanical Characterization of Thin Paper Materials
Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska HögskolaSammanfattning : Hur ser framtidens hållbara förpackning ut och vad är den tillverkad av? För att besvara denna fråga blir mikromekanisk karakterisering av material en viktig parameter att utforska och förstå. I synnerhet är mikromekaniken hos tunna pappersmaterial intressant då materialet har användningspotential i flera förpackningsapplikationer. LÄS MER
3. Microstructure and Mechanical Investigation ofCarbides Particles Reinforced High AusteniticManganese Steel
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : The objective of this study was to produce a metal matrix composite (MMC). This compositematerial proves highly suitable for scenarios involving abrasive wear, owing to the exceptionalhardness of carbide particles, in conjunction with the remarkable ductility and capacity for workhardening found in Hadfield steel.

4. Heteroepitaxial Growth of GaN Film on Si substrate by Magnetron Sputtering
Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologiSammanfattning : In this study, the effect of AlN buffer layer structure and morphology on the GaN films deposited on Si (111) substrate by reactive DC magnetron sputtering have been studied. For structural and morphological characterization X-ray diffraction (XRD) and Scanning electron microscope (SEM) were used. LÄS MER
5. 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].
