  4. 7. Interaction and adhesion at the interface between wood and paint, glue, lacquer measured with DMTA and SEM

    Author : Anna Backman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Abstract : The aim of the present thesis was to study the interface between wood (Pinus sylvestis) and synthetic polymers such as glue, lacquer and paint. The weakest part of these interfaces is always the bond. The long-term properties of bonds between wood and an adherend are those which are interesting. READ MORE

  5. 8. From bio-based residues to nanofibers using mechanical fibrillation for functional biomaterials

    Author : Linn Berglund; Kristiina Oksman; Monika Österberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanofibers; Industrial residues; Ultrafine grinding; Energy-efficiency; Network formation; Hydrogel; Trä och bionanokompositer; Wood and Bionanocomposites;

    Abstract : Bio-based resource utilization in different forms has been driven by societal, industrial and academic research interests towards the development of “green”, sustainable materials from renewable sources. Within this context, exploiting biomass from different industrial residues is further advantageous from an environmental and economic point of view, leading to minimization of residues by means of waste treatment and to the development of high-addedvalue- products.

    Abstract : Transparent wood (TW) shows interesting optical properties and offers a sustainable alternative to petroleum-based polymer glasses. The influence of the TW internal structure (e.g. READ MORE

  7. 10. Wood shrinkage in CT-scanning analysis

    Author : José Couceiro; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Abstract : Computed tomography (CT) can be used to study wood-water interactions in differentways, such as by determining wood moisture content (MC). The determination of MCrequires two CT images: one at the unknown moisture distribution and a second one ata known reference MC level, usually oven-dry MC. The two scans are then compared. READ MORE
