  1. 1. Investigation of plasma cleaning on molybdenum crystals for diagnostic mirrors in fusion devices

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hafssa Laabadi; [2023]
    Nyckelord :;

    Sammanfattning : In the long-term energy scenario, nuclear fusion is a promising low-carbon and sustainable energy source. The unavoidable exposure of the wall materials to the plasma is a big challenge in realizing a fusion reactor. The plasma-facing components (PFCs) in the reactor wall will experience erosion deposition in the surface materials. LÄS MER

  3. 2. The research on perfluoroalkyl and polyfluoroalkyl substances (PFASs) in different research areas from the 1950s to the present.

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Amanda Sahlin; [2017]
    Nyckelord :högflourerade ämnen; PFCs; perfluorinated chemicals; PFASs; Perfluoroalkyl and polyfluoroalkyl substances; poly - och perfluorerade alkylsubstanser; PFAS; Earth and Environmental Sciences;

    Sammanfattning : Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are found globally in the environment, in humans and in wildlife and it is still not sure how these substances affect humans and animals. This study was performed as a systematic review to examine when these substances first attracted attention in different research areas. LÄS MER

  4. 3. Characterization of the metabolic changes in chicken liver due to exposure of perfluorooctane sulfonate (PFOS) during the embryo development

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Ayan Au Musse; [2017]
    Nyckelord :PFCs; PFOS; Lipidomics; Lipid metabolism; UHPLC Q-TOF-MS;

    Sammanfattning : Perfluoroalkyl substances (PFASs) are anthropogenic compounds that have been classed as persistent organic pollutants (POPs) and are found in both commercial and industrial products. PFASs have been detected in different environmental matrices and have been found to bioaccumulate in all trophic levels. LÄS MER

  5. 4. MIFO fas 2: Riskklassning av PFAS-förorenad mark vid Sundsvall-Timrå Airport

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Emelie Haglund; [2016]
    Nyckelord :Sundsvall-Timrå Airport; PFCs; PFOS; fire-fighting foam; MIFO; contamination; Sundsvall-Timrå flygplats; PFAS; PFOS; MIFO; förorenat område; släckskum;

    Sammanfattning : The Methodology for inventory of contaminated sites (MIFO) is a method designed by the Swedish Environmental Protection Agency with an aim to facilitate agents and consultants during inventory of contaminated areas. It is structured into two stages, the first phase comprises oriented studies of the area while the second one consists of conceptual studies, such as field testing and analysis. LÄS MER

  7. 5. Greener Water Repellency? Feasible alternatives to fluoro chemicals for DWOR treatments on textiles

    Kandidat-uppsats, Högskolan i Borås/Institutionen Textilhögskolan

    Författare :Denize Åkerblom; Erik Göranzon; [2014]
    Nyckelord :Water and oil repellent; treatments; water and oil repellency; DWR; DWOR; perfluorinated compounds; PFCs; perfluorooctanoic acid; PFOA; perfluorooctane sulfonates; PFOS; dendrimers; organic silicon; hydrocarbon; hydrocarbon; aliphatic polyurethane; textiles; outdoor clothing; performance; UV-radiation; Martindale; washing;

    Sammanfattning : BACKGROUND: Perfluorinated compounds (PFCs) have been used as durable water and oil repellent treatments in clothing for more than 50 years. The reason for its popularity is related to the chemical structure, which also makes these compounds persistent in the environment. LÄS MER
