    Författare :Elisabet Boija; Gunnar Johansson; Per Lundahl; Christine Lagerquist Hägglund; Marja-Liisa Riekkola; Uppsala universitet; []
    Nyckelord :Biochemistry; Bilayer disk; Capillary electrophoresis; Detergent; Drug; Electrostatic interaction; Hydrophobic interaction; Immobilized liposome chromatography; Lignin; Lignin precursor model; Liposome; Membrane model; Octanol water partitioning; Partitioning; Phospholipid; Phospholipid bilayer; Sterol; Biokemi;

    Sammanfattning : The main aim of this thesis was to characterize membrane-solute interactions using artificial membranes in immobilized liposome chromatography or capillary electrophoresis. The partitioning of a solute into a cell membrane is an essential step in diffusion across the membrane. LÄS MER

  4. 23. NMR Diffusion Studies of Association in Surfactant Systems Inclusion Complexes, Micellar Solutions and Microemulsions

    Författare :Markus Nilsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; host-guest complexation; gemini surfactant; cyclodextrin; bolaform surfactant; self-diffusion NMR; pluronic; bicontinuous microemulsion; polydispersity; boosting effect;

    Sammanfattning : The aim of this thesis has been to investigate self-diffusion behavior of host-guest complex, microemulsion and polymer solution. Pulsed Field Gradient NMR (PFG-NMR) was shown to provide detailed molecular information in all system studied. LÄS MER

  5. 24. Surface modification approaches of cellulose nanofibrils and their effect on dispersibility

    Författare :Tahani Kaldéus; Eva Malmström; Tekla Tammelin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose nanofibrils; colloidal stability; re dispersibility; surface modification; bio-nanocomposites; interface; cellulosa nanofibriller; kolloidal stabilitet; re dispergerbarhet; ytmodifiering; bio-nanokompositer; gränssnitt; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : In the strive to find and develop sustainable bio-based materials an increased interest for nanocellulosic materials as attractive alternatives has arisen during the past decades. This can be attributed to their abundant renewability, remarkable inherent mechanical properties and their capability to be chemically modified. LÄS MER

  7. 25. Aspects of aquatic sampling and exploratory data analysis of hydrophobic organic compounds

    Författare :Harald Pettersen; Mats Tysklind; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : This thesis is based on seven papers describing studies conducted with samples from the Baltic Sea. It discusses some aspects on the use of multivariate methods for evaluation of data on hydrophobic organic compounds (HOCs) found in the aquatic environment. LÄS MER
