    Sammanfattning : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. LÄS MER

  3. 7. Optimization of hot strip drawing test methodology for hot forming of aluminium alloys

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

    Författare :Rabia Arshad; [2022]
    Nyckelord :Hot forming of aluminium; friction; high temperature lubrication; strip draw; wear.;

    Sammanfattning : The development of lightweight design for automotive applications has lasted for many years and is still increasing. Vehicles with light structures use less fuel, emit less CO2, and are better for the environment. LÄS MER

  4. 8. Life Cycle Assessment of typical projects of the distribution power network : Assessment, Improvement & Recommendations

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hugo Serres; [2022]
    Nyckelord :Life cycle assessment; GHG emissions; power infrastructures; Livscykelanalys; växthusgasutsläpp; energiinfrastrukturer;

    Sammanfattning : The carbon footprint of the power generation is studied for more than 30 years now. In order to curb GHG emissions, politics, industrials and consumers tend to take action to reduce the carbon intensity of the electricity mix, spread electrification and enhance usage efficiency.

  5. 9. Template-assisted Electrodeposition and Model Electrodes Studied by Electron Microscopy and High Energy X-ray Diffraction

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Hanna Sjö; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : There is a great interest in studying detailed changes at electrode surfaces during electrochemical processes to better understand the electrochemical reactions at the electrode surface-liquid interface and improve the electrode efficiency. The Au(110) surface has a known (1$\times$2) missing row reconstruction in vacuum conditions, which can change into higher-order (1$\times$3), (1$\times$5), and (1$\times$7) depending on environment.

  7. 10. Insights into the burning behaviour of wood in the cone calorimeter

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Ellinor Sanned; [2022]
    Nyckelord :Wood combustion; fire test; cone calorimetry; heat release rate; char formation;

    Sammanfattning : Climate change and its accompanying environmental issues have caused the building industry to use more environmentally friendly building materials. Wood have always been a buildingmaterial but due to the renewed interest in imparting sustainability and renewability, its usage has increased over the recent years. LÄS MER
