  1. 6. Exploring Particulate Filtration during Thermal Runaway in Lithium-Ion Battery Packs

    Master-uppsats, KTH/Kemiteknik

    Författare :Amanda Halvarsson; [2023]
    Nyckelord :battery pack; particles; thermal runaway; filtration; batteripack; partiklar; termisk rusning; filtrering;

    Sammanfattning : Med övergången till elektrifiering inom transport uppstår nya utmaningar när det gäller batterisystem som placeras i elfordon. Det finns för närvarande en möjlighet att minska riskerna med toxiciteten hos partiklar som sprutas ut med de gaser som bildas under termisk rusning i litiumjonbattericeller som är placerade i batterisystem.

  3. 7. Radiation Shielding Simulations for Small Satellites on Geostationary Transfer Orbit

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Anton Fetzer; [2022]
    Nyckelord :GTO; Foresail-2; CubeSat; Radiation Shielding; Geant4; Radiation Belts; GTO; Foresail-2; CubeSat; säteilysuojaus; Geant4; säteilyvyöhyke;

    Sammanfattning : The emergence of small and affordable satellites has led to rapid growth in the number of launched satellites over the past two decades. To save costs, small satellites often use mass-produced electronic components not explicitly designed for the radiation environment of space, which reduces reliability and makes them unsuitable for higher orbits.

  4. 8. Investigation of the Magnetic- and Electron Transport Properties of Fe/MgO Superlattices

    Kandidat-uppsats, Uppsala universitet/Materialfysik

    Författare :Ali Rostom; David Holmgren; [2022]
    Nyckelord :Fe MgO superlatice; interlayer exchange coupling; Van der Pauw; electronic transport; magnetic field; resistive properties; 3D memory storage;

    Sammanfattning : Anti-ferromagnetic interlayer exchange coupling between iron layers in Fe/MgO superlatices have recently been of interest among researchers for its potential application in 3D memory storage in computers (hard drives) and in the research field of spintronics. Thinfilms and bi-layers between the 10-100 ångström range in thicknesses were analyzed for its resistive properties during different conditions. LÄS MER

  5. 9. Use of the JET pedestal database to assess the role of ion temperature and plasma rotation on the discrepancy between ideal peeling-ballooning model and experimental data

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

    Författare :Max Eichenberger; [2022]
    Nyckelord :Nuclear fusion; Joint European Torus JET ; H-mode; pedestal; Edge-localized-modes ELMs ; Peeling-Ballooning; relative shift; ion temperature; plasma rotation; Kärnfusion; JET Joint European Torus ; H-läge; piedestal; ELM Edge Localized­Modes ; peeling-ballooning; relativ förskjutning; jontemperatur; plasmarotation;

    Sammanfattning : Next-generation and present fusion devices such as the Joint European Torus (JET) aim for plasma operations in H-mode, a plasma regime with high confinement and low loss of energy and fuel that results from a barrier for heat and particle transport at the plasma edge, the pedestal. Due to steep gradients of the density, temperature and pressure profiles, the pedestal experiences instabilities called Edge-localized-modes (ELMs) which lead to large fluxes of heat and particles that might damage machine components.

  7. 10. Reaction of Copper and Copper(I) Iodide with Iodine and Strong Field Ligands

    Master-uppsats, KTH/Tillämpad fysikalisk kemi

    Författare :Aya Ali; [2022]
    Nyckelord :in films; AFM; copper iodide; solar cells; transparent conductive films; tunnfilm; AFM; koppar jodid; solceller; transparent ledande film;

    Sammanfattning : Perovskit solceller (PSCs) är kända som 'ljusomvandling' enheter med ökad omvandlingseffektivitiet (PCE). PSCs är kända för detta flexibilitet och hög tolerans mot defekter och består av fem lager med olika material och egenskaper. LÄS MER
