  1. 1. Thermal degradation of PFAS in solid matter

    Master-uppsats, KTH/Kemi

    Författare :Tuqa Al-Badri; [2024]
    Nyckelord :PFAS; PFOS; PFOA; thermal degradation; sewage sludge; PFAS; PFOS; PFOA; termisk nedbrytning; avloppsslam;

    Sammanfattning : Per- och Polyfluorerade alkylsubstanser (PFAS) är syntetiskt framställda organiska föreningar som har använts i stor utsträckning i konsument- och industriprodukter. PFAS-substanser besitter attraktiva egenskaper såsom resistans mot väta, fett, fläckar och är dessutom värmetåliga. LÄS MER

  3. 2. Study case: The water-cooling effect on floating photovoltaic plants performance

    Master-uppsats, KTH/Energiteknik

    Sammanfattning : Floating solar technology is relatively new, and it comes with its own set of challenges and opportunities. This master thesis focuses on understanding how Floating Photovoltaic (FPV) projects perform compared to Ground-Based Photovoltaic (GPV) projects, in specific weather conditions. LÄS MER

  4. 3. Influence of different carbon sources on methane fluxes in sediments of eelgrass beds and unvegetated areas: a case study on the Swedish west coast

    Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Hampus Holmberg; [2023-06-22]
    Nyckelord :;

    Sammanfattning : One of the best ways to mitigate climate change is through natural carbon sequestration. An efficient way to mitigate climate change is through carbon sequestration from coastal habitats. LÄS MER

  5. 4. Yearly distribution and composition of per- and polyfluoroalkyl substances (PFAS) in Luleå wastewater treatment plant

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Moa Sjöberg; [2023]
    Nyckelord :PFAS; WWTP; Wastewater treatment; Consumer products; Precursors;

    Sammanfattning : PFAS (per- and polyfluoroalkyl substances) are a large group of substances that are used in a large variety of products because of their unique water and dirt repellent properties. The substances are extremely persistent and can spread over large distances in groundwater, surface water, and in the air, which makes them an environmental and a health concern. LÄS MER

  7. 5. Kurita : CARING FOR SOIL

    Master-uppsats, Konstfack/Industridesign

    Författare :Andrea García Portolés; [2023]
