  1. 21. On the interactions in cellulose systems : surface forces and adsorption

    Author : Monika Österberg; KTH; []
    Keywords : cellulose; hemicellulose; xylan; lignin; surface forces; adsorption; polyelectrolyte; SFA; AFM; ESCA; Langmuir-Blodgett films; chitosan; steric forces; bridging; adhesion;

    Abstract : In this thesis the interactions in cellulose systems havebeen studied with emphasis on surface forces and adsorptionphenomenon. The study was limited to surfaces and polymers ofinterest for papermaking. READ MORE

  2. 22. Effects of plasticizing and crosslinking on the mechanical and barrier properties of coatings based on blends of starch and poly(vinyl alcohol)

    Author : Asif Javed; Lars Järnström; Henrik Ullsten; Peter Rättö; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Citric acid; Glycerol; Polyethylene glycol; Barrier properties; Starch; Mechanical properties; Polyvinyl alcohol; Adhesion; Cross linking; Extrusion coating; Chemical Engineering; Kemiteknik;

    Abstract : In the last decades, intensive research has been carried out in order to replace oil-based polymers with bio-based polymers due to growing environmental concerns. So far, most of the barrier materials used in food packaging are petroleum-based materials. READ MORE

  3. 23. Erosion - Corrosion Resistance and Adhesion of Laser and Thermally Deposited Coatings in Fluidised Beds

    Author : Anders Hjörnhede; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coating; fluidised bed; HVOF; laser cladding; CFB; FBC; adhesion testing; PFBC; thermal spraying; arc spray; erosion - corrosion; acoustic emission;

    Abstract : High temperature erosion - corrosion is the major source for degradation of components such as heat exchangers, tubes, cyclones and water walls used in Fluidised Bed Combustion (FBC) plants. By coating the exposed components with a protective material, the degradation rate can be decreased. READ MORE

  4. 24. Flexible Composites - Strength, Deformation and Fracture Proecesses in Woven and D.O.S. Reinforcement Materials

    Author : Torbjörn Dartman; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kompositmaterial; Composite materials; Textile materials; Joints; Coated fabrics; Tear strength; Flexible composites; Damage resistance;

    Abstract : In this thesis the tensile strength, deformation, damage resistance and tear propagation for flexible composites are analysed. There are two essential requirements common to all flexible composites; namely, high tearing strength and good matrix-to-fabric adhesion. The interaction of fabric and matrix is complex. READ MORE

  5. 25. A Fundamental Adhesion Model for Asphalt

    Author : Åsa Laurell Lyne; Björn Birgisson; Robert Lytton; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : One of the mechanisms for the deterioration of asphalt is debonding. This is often referred to as stripping. Most losses of adhesion at the bitumen-aggregate interface are attributed to the action of water leading to a reduction in properties such as tensile strength, tensile stiffness and wear resistance.
