  1. 31. Suppression of Li-ion Battery Fires

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Linfan Cai; [2023]
    Keywords : Lithium-ion Battery; Fire Suppression System; Extinguishing Agent; Thermal Runaway; Battery Energy Storage System; Electric Vehicle; Technology and Engineering;

    Abstract : This thesis presents a systematic literature review of fixed fire suppression systems and extinguishing agents for lithium-ion battery (LIB) fires. The review identifies 85 relevant sources published between 2013 and March 2023, and categorises different research experiments into cell-level, module-level, electric vehicle (EV) pack-level, battery energy storage system (BESS) rack-level and warehouse storage experiments, according to LIB configurations.

  5. 34. Development and Evaluation of an Enzyme-Based Sunscreen

    University essay from Lunds universitet/Bioteknik; Lunds universitet/Bioteknik (master)

    Author : Karolina Eriksson Torfgård; [2023]
    Keywords : Enzyme activity; UV-filter; Protease; Biotechnology; Technology and Engineering;

    Abstract : Ultraviolet radiation (UVR), specifically of UVA and UVB, has been associated with the development of both photoaging and photo-carcinogenesis, potentially leading to cancer. The use of sun protection in the form of UV filters is known to minimize these damages. READ MORE

  6. 35. Building performance optimisation tools for the decarbonisation of Swedish buildings

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Nadja Baden; Marziyeh Taghizadeh; [2023]
    Keywords : Optimisation; Parametric design; Decarbonisation; Renovation; Technology and Engineering;

    Abstract : To mitigate climate change and reach Sweden’s goal of becoming carbon neutral by 2045, or at an earlier stage of 2030 for 23 Swedish cities, urgent action is required to reduce greenhouse gas emissions. Due to the building sector’s significant contribution to carbon emissions, a crucial aspect in achieving these goals is improving the energy efficiency of existing buildings, as most of these will still be in use by this time.
