  1. 1. On the stability of current collectors in high-voltage lithium-ion batteries containing LiFSI electrolytes

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

    Författare :Kevin Carlö; [2023]
    Nyckelord :LiFSI; high-voltage; anodic dissolution; corrosion; aluminum; current collector; electrolyte; battery;

    Sammanfattning : The increasing energy demand requires a transition from fossil fuels to renewable resources. Lithium-ion batteries (LIBs) offer a promising solution as efficient energy storage devices. However, the aluminum current collector (CC) in LIBs is susceptible to anodic dissolution above 3 V vs. LÄS MER

  3. 2. Uncertainties in Proton Therapy and Their Impact on Treatment Precision : Looking at Mechanical and Beam Alignment Uncertainties

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Albin Karlsson; [2022]
    Nyckelord :Proton therapy; Machine quality assurance; Uncertainties; Robust optimization;

    Sammanfattning : With the growing use and complexity of proton therapy, the safety and accuracy of the machines becomes increasing important. This, to be able to deliver the prescribed dose to the target while minimizing the dose to healthy tissue. LÄS MER

  4. 3. Optimization and Characterization of Luminescent Materials for the ESS Proton Beam Imaging System

    M1-uppsats, Lunds universitet/Centrum för analys och syntes
