  1. 1. Geomorphic change along the Rönne river : Effects caused by dams

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Adam Scheér; [2024]
    Nyckelord :fluvial morphology; dams; GIS; Rönne river;

    Sammanfattning : Many rivers can shape their path through the landscape with erosion and deposition where the riverbed and riverbanks both shape the direction and energy of the flow. The river flow can erode the riverbanks and create meanders which is when the river creates bends in its path that become increasingly curved. LÄS MER

  3. 2. Influence of pulsing on PVD TiAlN coating microstructure and mechanical properties : Master thesis project on the impact of deposition parameters on performance and properties of PVD titanium aluminum nitride.

    Master-uppsats, Karlstads universitet

    Författare :Marcus Roseen; [2023]
    Nyckelord :;

    Sammanfattning : This thesis investigates the influence of pulsing on the mechanical properties of PVD TiAlN coatings. The thesis focuses on defects caused by droplets during the arc-evaporation technique by altering the duty time, which affects mechanical properties. LÄS MER

  4. 3. Heteroepitaxial Growth of GaN Film on Si substrate by Magnetron Sputtering

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Zahra Mohammadianrasnani; [2023]
    Nyckelord :GaN; Sputter epitaxy; Thin film;

    Sammanfattning : 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. 4. Electrochemical Characterisation of LiFePO4-Coated Carbon Fibres: A Comparative Electrochemical Analysis of Three Coating Methods

    Master-uppsats, KTH/Tillämpad elektrokemi

    Författare :Julia Szecsödy; [2023]
    Nyckelord :Structural battery composite; Carbon fibres; Lithium-ion battery; Electrophoretic deposition; Spray coating; Powder impregnation; Strukturella batteri kompositer; Kolfiber; Litiumjon batteri; Elektroforetisk beläggning; Sprutbeläggning; Pulverimpregnering;

    Sammanfattning : Kolfiber CF kan användas som positiv elektrod i strukturella batterier om de beläggs med ett aktivt material, såsom litiumjärnfosfat LFP. Fördelen med att använda kolfibrer som elektroder är att de samtidigt kan bära mekanisk belastning och lagra elektrisk energi. Det finns flera tekniker för att belägga kolfibrerna. LÄS MER

  7. 5. The Effect of Process Parameters on Columnar-To-Equiaxed-Transition (CET) During Electron Beam-Powder Bed Fusion of Ferritic Stainless Steel

    Master-uppsats, KTH/Materialvetenskap

    Författare :Doom Eleanor Ihensekhien; [2022]
    Nyckelord :Additive manufacturing; E-PBM; Inoculation; process parameters; TiN; CET;

    Sammanfattning : Electron Beam Powder Bed Fusion manufacturing of components is an additive manufacturing process that is complex and has widespread advantages for aerospace and many industrial processes. It reduces costs and has a larger powder particle size requirement. LÄS MER
