  1. 1. Visualization, modeling and consequences of residual stresses in glass frit sealing of a UV light source

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Mikrosystemteknik

    Författare :Vilma Hurtigh Grabe; [2023]
    Nyckelord :bonding; micro system; glass frit; sealing; finite element; modeling; glass; mikrosystem; sammanfogning; glasfog; fog; finita element; modellering; glas;

    Sammanfattning : PureFize Technologies AB develops and manufactures a broadband ultraviolet (UVC) light technology device that is mercury-free and based on nanotechnology, using the principle of field emission. The light source is made of Ti and glass, which are hermetically bonded, using a low-temperature glass frit, at elevated temperatures. LÄS MER

  3. 2. How does temperature affect the severity of Bd infection in the common toad (Bufo bufo)? : A test of thermal mismatch hypothesis

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Felix Fridh; [2023]
    Nyckelord :chytridiomycosis; amphibians; fungi; fungus; thermal mismatch hypothesis; bufobufo; common toad; Batrachochytrium dendrobatidis; Bd;

    Sammanfattning : Batrachochytrium dendrobatidis (Bd) is a fungus that causes chytridiomycosis in amphibians. This fungus is an invasive species that has spread all over the world and is causing mass deaths in many areas. Bd has an efficient life cycle which targets suitable hosts and causes disturbances in amphibian osmoregulation and eventually death. LÄS MER

  4. 3. Life Cycle Assessment of Borehole Thermal Energy Storage

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Saga Karlsson; [2022]
    Nyckelord :;

    Sammanfattning : Borehole thermal energy storage (BTES) is a technology used to store energy between seasons. It could therefore be a solution to the seasonal mismatch between the use and production of (renewable) energy, which can be used to increase energy efficiency and reduce greenhouse gas emissions.

  5. 4. Investigating and Fabricating High-K (Al2O3) and Ferroelectric (HfO2) MIM-Capacitors for use in BEOL Fabrication Applications

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

    Författare :Thomas Hackett; [2021]
    Nyckelord :atomic layer deposition ALD ; ferroelectric; metal-insulator-metal MIM capacitors; low thermal budget; rapid thermal annealing RTA ;

    Sammanfattning : Integration of high-K Metal-Insulator-Metal (MIM) capacitors in the Back-end-of-line (BEOL) is a topic of interest for the further development of the process at KTH Royal Institute of Technology. MIM-capacitors benefit from having constant capacitance values over a range of voltages and/or frequencies. LÄS MER

  7. 5. THE POTENTIAL OF A LATENT HEAT THERMAL ENERGY STORAGE : An Investigation on Rocklunda's Sport Facilities

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Anton Egersand; Emil Fransson; [2021]
    Nyckelord :LHTES; PCM; TES; Al-Si; Latent Heat; High-Temperature PCM; VRE;

    Sammanfattning : The world is ever increasing in its energy usage, making energy that is sustainable and secure harder to achieve. To fulfil the Paris agreement to limit global warming, the world needs to transition from fossil fuels toward more renewable energy sources, like wind and solar, but these sources have fluctuation in supply which often create a mismatch with demand.
