  1. 1. Discharge and Flame Chemistry in Lithium-Ion Battery Vent Gases : Investigations using Breakdown Experiments with Laser-Based Diagnostics

    Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Författare :Julia Lövgren; [2023]
    Nyckelord :PLIF; Laser-induced fluorescence; Laser-based diagnostics; Combustion; Lithium-ion battery; Physics and Astronomy;

    Sammanfattning : Due to the environmental impact of fossil fuels, there has been a growing interest in lithium-ion batteries for electric vehicles. However, safety concerns have arisen regarding potential fire hazards associated with the vent gases of these batteries. LÄS MER

  3. 2. 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.

    Sammanfattning : Syfte  Syftet med föreliggande studie var att undersöka hur böjhållfastheten på zirkonia påverkas av värmebehandling, ytbehandlingar vid re-cementering och långtidsförvaring i cirka två år. Material och metod I en tidigare studie av A.Cervenka och H. LÄS MER

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

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

    Författare :Emelie Wiklund; Anton Järild; [2021]
    Nyckelord :Chemical Engineering; Luminescent materials; Cr-doped Alumina; Proton Beam Imaging System; ESS; Chemistry; Technology and Engineering;

    Sammanfattning : Spallation sources such as European Spallation Source (ESS) produces neutrons by bombarding high-energy protons onto the target wheel. To determine the location of the proton beam a Proton Beam Imaging (PBI) system will be installed. LÄS MER

  7. 5. A comparison between LiF, Al2O3 and NaCl pellets for luminescence dosimetry based on clinical and laboratory measurements

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Edita Solak; [2021]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Radiation protection is of importance for the general public, patients and personnel in many different situations: rare accidents involving ionizing radiation, medical examinations or work tasks in the medical clinic or nuclear industry to name a few. Optimization in radiation protection and limitation of radiation doses are essential to prevent overexposure and for reducing negative health consequences. LÄS MER
