  1. 11. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Ahsan Ali; [2023]
    Nyckelord :High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

    Sammanfattning : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

  3. 12. Estimating Photovoltaic capacity using customs data : Model development of the tool NJORD and photovoltaics' characterization and impact on the African continent

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Albin Åbrink; [2023]
    Nyckelord :Photovoltaic; Trade analysis; Development Goals; Africa;

    Sammanfattning : Photovoltaics (PV) is one of the fastest growing power sources in the world in the last twenty years, being the most installed power source in almost half of the world's countries in 2020. Despite this, precise tracking of installations of PV does not exist in most of the world's markets due to PVs unique scalability and modularity. LÄS MER

  4. 13. Synthesis and Characterization of Materials for Carbon Based Hybrid Asymmetric Supercapacitor Electrodes

    Master-uppsats, KTH/Tillämpad fysikalisk kemi

    Författare :Avital Cherednik; [2023]
    Nyckelord :Supercapacitor; hybrid supercapacitor; metal oxide nanoparticles; carbon electrodes; ionic liquid; Superkondensator; hybrid superkondensator; metaloxid nanopartiklar; kolelektroder; jonvätska;

    Sammanfattning : Superkondensatorer är energilagringsenheter som har uppmärksammats mer under det senaste decenniet. Några av de fördelar som dessa enheter har varit är lagring av hög effekttäthet, förlängda livscykler och snabba laddnings- och urladdningstider. LÄS MER

  5. 14. Exhaust system for hydrogen fuelled combustion engines: effect of high-water content on the SCR vanadium catalyst

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Cecilia Zambelli; [2023]
    Nyckelord :;

    Sammanfattning : Transportation represents a key secot in the journey towards a greener future, and alternative solutions are needed to meet the decarbonaisation need. Hydrogen internal combustion engines could represent a solution in the short-term, allowing for emission reduction with limited modification to the already existing traditional combustion engines.

  7. 15. Hur kultur formar narrativ : En jämförande studie av sociokulturella värden i västerländskt och österländskt berättande

    Kandidat-uppsats, Umeå universitet/Institutionen för kultur- och medievetenskaper

    Författare :Nora Eriksson; [2023]
    Nyckelord :South Korea; cinema; narrative; sociocultural values; Sydkorea; film; narrativ; sociokulturella värden;

    Sammanfattning : This is a comparative cultural study from a literary perspective, focusing on characterization in Western and Eastern storytelling. By comparing a selection of Korean dramas with Anglo-American TV series and films, I want to examine possible similarities and differences in the character representation, emotional expressions and philosophies of the stories, as well as how these may be grounded in different cultural structures.
