  1. 6. 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

  3. 7. Cereal Dietary Fibre - Physicochemical Properties and Suitability for Addition to Low-Fat Meat Products

    Författare :Karin Petersson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dietary fibre; cereals; oat bran; rye bran; wheat bran; barley fibre; hydrolytic enzymes; physicochemical properties; low-fat sausages; low-fat meatballs; sensory perception; texture;

    Sammanfattning : It is well known that dietary fibre is good for the health. Cereals, and in particular the outer parts of the cereal kernels, are rich in dietary fibre. Rye bran, wheat bran, oat bran and barley fibre have been investigated regarding their suitability as additives in low-fat meat products. LÄS MER

  4. 8. Pulp displacement washing - An investigation of the influence of fibre and bed properties using a novel measurment technique

    Författare :Jenny Lindau; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; displacement washing; pulp properties.; measurement technique; compression; dispersion; fibre damage; local properties; kraft pulp;

    Sammanfattning : There are many incentives for making the pulp washing process as efficient as possible: an efficient separation of the pulp from the black liquor will increase energy efficiency, reduce costs by minimizing the need for make-up chemicals and improve the bleaching process. Research in this area has, however, been more or less neglected and in the existing literature there are many discrepancies as to how different parameters influence the washing process. LÄS MER

  5. 9. Fibre Bragg Gratings : Characterization, Realization and Simulation

    Författare :Ingemar Petermann; Ari Friberg; Sten Helmfrid; Morten Ibsen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bragg gratings; optical fibres; optical fibre components; Physics; Fysik;

    Sammanfattning : The main topic of this thesis is realization and characterization of fibre Bragg gratings. A novel versatile grating fabrication technique is developed and a number of gratings are realized, showing the potential of the system. LÄS MER
