    Sammanfattning : Many aspects of modern human life pose a strain on the delicate ecosystems around us. One example is marine litter – mainly various plastic items – which accumulate in the marine environment, where they cause problems for the fauna, such as ingestion and entanglement. LÄS MER

  4. 13. Two-dimensional Nanocomposites Based on Cellulose Nanofibrils and Graphene Oxide

    Författare :Hanieh Mianehrow; Lars Berglund; Aji Mathew; KTH; []
    Nyckelord :Cellulose nanofibrils; graphene oxide; orientation; reinforcement; oxygen barrier; bio-nanocomposite; moisture; molecular adhesion; interfacial shear strength.; Nanocellulosa; grafenoxid; orientering; förstärkning; syrebarriär; bionanokomposit; fukt; molekylär adhesion; skjuvhållfasthet hos gränsytan.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Two-dimensional (2D) nanocomposites based on cellulose nanofibrils (CNF) and 2D nanomaterials are of interest as sustainable materials combining functional and structural properties. To achieve reinforcement effects from 2D nanomaterials, their orientation and dispersion state in the CNF matrix are important. LÄS MER

  5. 14. Bonding veneers using only heat and pressure : focus on bending and shear strength

    Författare :Carmen Cristescu; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; self-bonding; auto-adhesion; LVL; beech; Fagus Sylvatica; high-temperature; pressure; Wood Technology; Träteknik;

    Sammanfattning : A compact laminated board can be obtained by pressing layers of veneers with no other material or substance placed between them. The process does not require the use of steam pretreatment, surface activation methods, a gastight press, friction or adhesives. It strictly involves the heat and the pressure induced by the press in the veneers. LÄS MER

  7. 15. The Influence of Molecular Adhesion on Paper Strength

    Författare :Malin Eriksson; Lars Wågberg; Orlando Rojas; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : This thesis deals with the influence of molecular adhesion on paper strength. By combining the use of high-resolution techniques and silica/cellulose surfaces, with various fibre–fibre and sheet testing techniques, new information regarding the molecular mechanisms responsible for paper strength has been obtained.
