  1. 1. Alkylglucosides - physical chemical properties

    Författare :Frederik Nilsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; penetration experiment; DSC; SAXS; NMR self-diffusion; phase separation; size micro-structure; aggregate-aggregate interaction; liquid crystalline phases; micelles; alkylglucosides; phase diagrams; fluorescence.; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The aim of this study is to characterise the physical-chemical properties of alkylglucosides. Alkylglucosides are non-ionic surfactants synthesized from glucose and a fatty alcohol. The glucose molecule constitutes the hydrophilic head group and the fatty alcohol constitutes the hydrophobic tail. LÄS MER

  3. 2. Environmentally adapted lubricants : properties and performance

    Författare :Anders Pettersson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Sammanfattning : The lubricants of the future have to be more environmentally adapted, show a higher level of performance, and give a lower total life cycle cost (LCC) than the lubricants that are used today. One way to be able to produce, choose and formulate these lubricants is to have good knowledge about the properties of the base fluids and their additive response. LÄS MER

  4. 3. Fate and exposure assessment of PCDD/Fs at contaminated sites

    Författare :Annika Åberg; Karin Wiberg; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; contaminated sites; dioxins; PCDD F; exposure; food chain; modeling; risk assessment; physical-chemical properties; förorenade områden; dioxiner; PCDD F; exponering; födokedja; modellering; riskbedömning; fysikaliska-kemiska egenskaper; Environmental chemistry; Miljökemi;

    Sammanfattning : Polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzo-furans (PCDFs) belong to the most toxic compounds known to science and they are defined as Persistent Organic Pollutants (POPs) under the Stock-holm Convention. The general human exposure to PCDD/Fs is primarily through dietary intake. LÄS MER

  5. 4. Physical, Chemical and Biochemical Modifications of Industrial Softwood Kraft Lignin for Different Applications

    Författare :Miao Wang; Jiebing Li; Mikael Lindström; Elisabeth Sjöholm; Gunnar Westman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Sammanfattning : Various technical lignins, e.g. industrial Softwood Kraft lignin (SKL), are now largely available while they are generally underutilized due to their heterogeneous and complicated structures and/or the poor properties. LÄS MER

  7. 5. Confronting new challenges in chemical assessment : emerging contaminants and climate change

    Författare :Deguo Kong; Ian Cousins; Matthew MacLeod; Mick Whelan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; emerging chemicals; climate change; fate; multimedia model; risk assessment; physical-chemical property; uncertainty; Arctic; Baltic; time series; persistent organic pollutants; temporal trend; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Both chemical-specific (e.g. physical-chemical properties) and environmental (e.g. LÄS MER
