  3. 17. Modelling and Optimisation of Relativistic Magnetron with Transparent Cathode : Applications for High-Power Microwaves

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :David Sawert; [2023]
    Nyckelord :Relativistic Magnetron; RM; High-Power Microwaves; HPM; Particle-in-Cell; PIC; MAGIC3D; TE11;

    Sammanfattning : This thesis aimed to investigate the relativistic magnetron (RM), which is a high-power microwave (HPM) source. Since the RM can generate high-intensity microwave radiation, it can be used as a pulsed electromagnetic weapon to target electronic systems in different objects, such as drones, missiles, or vehicles.

  4. 18. Electrochemical strategies to retrieve lost capacity in Li-ion batteries by reversed Li-trapping

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Oorganisk kemi; Uppsala universitet/Strukturkemi

    Författare :Christopher Thulin; [2023]
    Nyckelord :Electrochemistry; lithium trapping; lithium-ion battery; diffusion;

    Sammanfattning : Since the transportation sector wants to move away from fossil fuels and become more dependen ton clean and green energy, the use of rechargeable batteries is a good solution. Lithium-based batteries work very well as rechargeable batteries in electric vehicles. LÄS MER

  5. 19. Sublimation temperature prediction of OLED materials : using machine learning

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Analys och partiella differentialekvationer

    Författare :Niklas Norinder; [2023]
    Nyckelord :Semiconductors; OLED; machine learning; vapor deposition; sublimation; molecular property prediction; regression; ensemble learning; deep learning;

    Sammanfattning : Organic light-emitting diodes (OLED) are and have been the future of display technology for a minute. Looking back, display technology has moved from cathode-ray tube displays (CRTs) to liquid crystal displays (LCDs). Whereas CRT displays were clunky and had quite high powerconsumption, LCDs were thinner, lighter and consumed less energy. LÄS MER

  7. 20. Freestanding graphite cathode with graphene additive for aluminum dual-ion batteries

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Adam Rosvall; [2023]
    Nyckelord :Aluminum ion batteries; Dual-ion batteries; Graphite; Graphene; Ionic liquid; Phase inversion method;

    Sammanfattning : In today’s fast adjustment to renewable energy, new battery technologies are needed to meetthe ever-growing demands of energy storage. Cheaper and easier to produce materials areneeded, as well as materials with a lower environmental impact. LÄS MER
