  3. 27. Improved Adhesion Between Ethylene Polymers and Aluminium

    Författare :Anders Strålin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Adhesion between aluminium and polymers is important in a wide variety of applications. The aim of the present work was to improve adhesion in polyethylene- aluminium laminates by surface modification of aluminium. The treatments examined were hydration in boiling water and phosphatation by immersion in dilute phosphoric acid solutions. LÄS MER

  4. 28. Formation and properties of polyelectrolyte multilayers on wood fibres : influence on paper strength and fibre wettability

    Författare :Rikard Lingström; Lars Wågberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polyelectrolyte; multilayer; adsorption; reflectance; contact angle; dynamics; paper; mechanical properties; individual; wood fibre; Chemistry; Kemi;

    Sammanfattning : The work in this licentiate thesis examines the adsorption of polyelectrolyte multilayers (PEM) onto wood fibres as a new way to influence the properties of the fibre surfaces and hence the fibres. Fundamental aspects of PEM formation on wood fibres have been studied, and discussed in terms of paper strength and wood fibre wettability. LÄS MER

  5. 29. Biomedical Applications of Bacterial Cellulose Fermentation, Morphology and Surface Properties

    Författare :Aase Katarina Bodin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocompatibility; xyloglucan epitopes; mechanical properties; cell adhesion; tubular fermentation; morphology; Bacterial cellulose; surface properties; meniscus mold; crystal formation.; ozonation; adsorption;

    Sammanfattning : Because average life expectancy has increased and peoples lifestyles have changed, degenerative diseases have become a critical issue. The demand for biomedical materials to replace or improve major body systems (skeletal, circulatory and nervous, etc.) will increase as people strive to maintain good quality of life. LÄS MER

  7. 30. Wafer Bonding for Spaceflight Applications : Processing and Characterisation

    Författare :Kerstin Jonsson; Maaike Visser-Taklo; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; wafer bonding; oxygen plasma; wet chemical; anodic bonding; gamma irradiation; proton irradiation; temperature cycling; vibration; shock; Weibull; adhesion quantification; double cantilever beam; tensile; chevron; blister; Teknisk fysik; Engineering physics; Teknisk fysik;

    Sammanfattning : Bonding techniques intended for assembling space microsystems are studied in this work. One of the largest problems in bonding pre-processed semiconductor wafers are the severe process restrictions imposed by material compatibility issues. LÄS MER
