  1. 26. Asymmetrical Flow Field-Flow Fractionation in the Separation, Characterization and Application of Wine Particle Matter

    Författare :Daniel Osorio Macias; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AF4-UV-MALS-dRI; wine colloids; wine macromolecules; phenolic compounds; polysaccharides; winemaking;

    Sammanfattning : Wine particle matter is mainly constituted by wine colloids and wine macromolecules. These wine colloidal and macromolecular compounds are barely studied, possibly due to the difficulty in facing the challenges that their study merits. LÄS MER

  3. 27. Salting-out of Colloidal Latex Particles Grafted with Poly(ethylene glycol)

    Författare :Kristin Jonsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PEG; fluorinated colloids; monodisperse spheres; steric stability; emulsion polymerization; SAXS; crosslinking; salting-out; interfacial tension; SANS;

    Sammanfattning : Colloidal particles dispersed in a medium are important both in nature and in industry. The stability of colloidal particles is determined by the interactions between them and can be improved by steric stabilization. There is no conclusive understanding of how these sterically stabilized particles become unstable. LÄS MER

  5. 29. The impact of groundwater chemistry on the stability of bentonite colloids

    Författare :Sandra Garcia Garcia; Mats Jonsson; Per Claesson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear chemistry; Kärnkemi;

    Sammanfattning : I det svenska djupförvaret för kärnbränsle ska kompakterad bentonit användas som barriär mellan kopparkapslar med utbränt kärnbränsle och berget. I kontakt med vattenförande sprickor kan bentonitbarriären under vissa omständigheter avge montmorillonitkolloider. LÄS MER

  7. 30. Molecular Interactions in Thin Films of Biopolymers, Colloids and Synthetic Polyelectrolytes

    Författare :Johansson Erik; Lars Wågberg; Andreas Fery; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polyelectrolyte multilayers; Layer-by-Layer assembly; Adhesion; Adsorption; Young s modulus; Mechanical buckling; AFM; JKR; SPAR; QCM-D; SIEBIMM; PAH; PAA; Starch; NFC; Nanocellulose;

    Sammanfattning : The development of the layer-by-layer (LbL) technique has turned out to be an efficient way to physically modify the surface properties of different materials, for example to improve the adhesive interactions between fibers in paper. The main objective of the work described in this thesis was to obtain fundamental data concerning the adhesive properties of wood biopolymers and LbL films, including the mechanical properties of the thin films, in order to shed light on the molecular mechanisms responsible for the adhesion between these materials.
