  1. 21. Alternative Adsorption Materials for Treatment of Contaminated Waters

    Författare :Yuliya Kalmykova; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adsorption; Sphagnum peat; Heavy metals; Fiber ash;

    Sammanfattning : The thesis presents a study of adsorbent materials for treatment of contaminated waters and remediation of contaminated soils. Natural and waste product materials showed high adsorption capacity for metals and organic pollutants and proved to be a good alternative to commercial adsorbents. LÄS MER

  3. 22. Adsorption Properties of Triblock Copolymers at Solid Surfaces

    Författare :Krister Eskilsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; Ellipsomery; Surface force; Adsorption; Triblock Copolymer;

    Sammanfattning : The interfacial behaviour of nonionic triblock copolymers of the type poly(ethylene oxide-tetrahydrofurane-ethylene oxide) has been systematically examined at different types of surfaces. It is shown how the chemical nature of the substrate greatly influences the adsorption behaviour of block copolymers. LÄS MER

  5. 24. Adsorption of xylans on cellulosic fibres -Influence of xylan composition on adsorption characteristics and kraft pulp properties

    Författare :Tobias Köhnke; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Xylan; Hornification; Lignin-carbohydrate complexes; Cationization; Isolation; Softwood kraft pulp; Extraction; Adsorption;

    Sammanfattning : Xylans are polysaccharides present in large amounts in cell walls of vascular plants. They possess an inherent affinity to cellulose and will thus adsorb irreversibly on cellulose surfaces. LÄS MER

  7. 25. Making sense of adsorption : Attempting to explain the adsorption of histatin 5 with models, metaphors, and machines

    Författare :Kristin Hyltegren; Beräkningskemi; []
    Nyckelord :Intrinsically Disordered Proteins; histatin 5; adsorption; ellipsometry; Monte Carlo simulations; coarse graining; charge regulation;

    Sammanfattning : This thesis summarises two studies in which the main purpose was to find out how and why the amount of the protein histatin 5 that adsorbs to negatively charged surfaces changes with pH and ionic strength. Histatin 5 is an intrinsically disordered saliva protein, and in the oral environment it adsorbs to tooth enamel. LÄS MER
