  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. Evaluation of antioxidant effect of an algae extract on skin: in vitro study

    Kandidat-uppsats, Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Författare :Oday Al Mustafa; [2023]
    Nyckelord :Algae extract; antioxidant; DPPH; microalgae; ROS; skin covered oxygen electrode; skin;

    Sammanfattning : Algae extracts are used as cosmetic products and used as additives in specific foods because of their antioxidant activity. Reactive oxygen species (ROS) such as hydrogen peroxide and superoxide radicals are toxic on the skin and can be scavenged by antioxidants, which are abundant in microalgae. LÄS MER

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Alexander Petersson; [2023]
    Nyckelord :Electrical Discharge; Electrical Arc; Spark Discharge; Combustion; Ignition; Lithium-Ion Battery; Thermal Runaway; Vent Gases; Breakdown Voltage; Ionization; High-Speed Imaging; Technology and Engineering; Chemistry;

    Sammanfattning : The increasing drive for sustainable and eco-friendly transportation has made the electrification of cars a top priority in the energy and transportation sectors. Ensuring the safety of electrical vehicle (EV) batteries is of the utmost importance. LÄS MER

  5. 4. Decreasing barrier while maintaining shelf-life for highly sensitive products - A more recyclable and sustainable packaging for infant formula

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Eva Weishaupt; [2020]
    Nyckelord :infant formula; packaging material; lipid oxidation; TBARS assay; shelf-life; Technology and Engineering;

    Sammanfattning : With increasing concerns about environmental impacts of the food that is consumed, so is also the concern about packaging materials. This also comprises the packaging that is currently used to pack infant formula (IF), very often containing aluminum as the barrier material. LÄS MER

  7. 5. DNA damage – a novel method to measure the rate of single-stranded breaks from fragmenting dsDNA in nanochannels – theory and modeling

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Magnus Brander; [2020]
    Nyckelord :biophysics; DNA damage; single-stranded breaks; double-stranded breaks; Bayesian inference; Brownian motion; Gillespie algorithm; photosensitized DNA damage; Physics and Astronomy;

    Sammanfattning : Damage to DNA can cause death to an individual cell and serious harm to the host organism. Photosensitized reactions are one cause of DNA damage. It can lead to destructive chemical reactions targeted to a base of the DNA as well as a breakage along one or both of the DNA strands. LÄS MER
