    Sammanfattning : Executive summary Today, packaging has gained a significant role in the food industry as well as other industries. Paper substrates that have been coated in some ways are typically used to make packaging. The amount and type of pigment used in the formulation determine whether this coating is a pigment coating or a barrier coating. LÄS MER

    Sammanfattning : Poly- and perfluorinated alkyl substances (PFASs) is a group of more than 5000 different substances, of which all consist of a fluorinated carbon chain resulting in a strong bond. Most of these substances are shown to be persistent, bioaccumulative and toxic for both humans and the environment. LÄS MER

  4. 23. GIANT UNILAMELLAR VESICLES FOR PEPTIDE-MEMBRANE INTERACTION STUDIES USING FLUORESCENCE MICROSCOPY

    Master-uppsats, Linköpings universitet/Biofysik och bioteknik

    Författare :Martin Nilsson; [2020]
    Nyckelord :Giant unilamellar vesicles; Lipid rafts; Fluorescence microscopy; Drug delivery;

    Sammanfattning : Vesicles are a type of biological or biomimetic particle consisting of one or more often spherical bilayers made up of amphipathic molecules, creating a closed system. They can function as an encapsulating device, holding hydrophilic molecules on the inside of the bilayer membrane(s) or hydrophobic molecules in the non-polar interstitial space in the middle of the bilayers.

  5. 24. Development of corrosion resistant coatings using natural biopolymer and pollen

    Master-uppsats, KTH/Materialvetenskap

    Författare :Alessandro Armani; [2020]
    Nyckelord :;

    Sammanfattning : Corrosion is a mechanism that highly reduces the lifetime of metals in different environments, especially in water or moisture environment. The worldwide maintenance cost due to corrosion is estimated in billions of dollars per year, and actual solutions in terms of coating usually contains toxic or environmentally harmful species.

  7. 25. Binding of per- and polyfluoroalkyl substances (PFASs) to organic soil horizons of peat and mor : effect of solution chemistry and soil organic matter composition

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Jennifer Makselon; [2019]
    Nyckelord :sorption; electrostatic interactions; isotherms; partitioning coefficient; soil organic matter; cation; PFOS; PFOA; desorption;

    Sammanfattning : The understanding of sorption processes of per- and polyfluoroalkyl substances (PFASs) in soils is important for the determination of their fate and transport in the environment. The sorption behavior of PFASs of varying chain length and hydrophilic headgroup was studied in three organic soils, two peat soils and one mor layer, with differing chemical composition of the soil organic matter (SOM).
