  1. 6. Fungal degradation patterns and toxicity of furfurylated wood

    Författare :Annica Pilgård; RISE; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Daphtox; Quantitative real-time PCR; Furfurylation; Microtox; Basidiomycota; Acetylation; Wood modification.; Daphnia magna; Thermal modification; Trametes versicolor; Decay; Vibrio fischeri;

    Sammanfattning : The demand for timber products is increasing with global population and affluence. Concerns regarding conventionally used toxic wood preservatives and the deforestation of tropical forests have become more prominent both socially and politically. Wood based products are generally recognised as an environmentally favourable raw material. LÄS MER

  2. 7. Studies on Industrial-Scale Thermal Modification of Wood

    Författare :Ola Dagbro; Lidia Gurau; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forestry and Wood Technology; Skog och träteknik; Wood Physics;

    Sammanfattning : Wood as a raw material is useful for many purposes even though some properties are less than optimal, for example, dimensional stability and durability. These characteristics can however be improved by different treatment methods. LÄS MER

  3. 8. Biochemical modification of wood components

    Författare :Peter Josefsson; Lars Wågberg; Mark Rutland; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : The degradation of cellulose found in wood is one of the most important degradation processes for the carbon flux on earth. The degradation is performed by microorganisms that typically use enzymes. LÄS MER

  4. 9. Tribology of hot forming tool and high strength steels

    Författare :Jens Hardell; Robert J. K. Wood; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : Tribological research pertaining to moving machine components operating at elevated temperatures has so far received only limited attention despite the fact that many technological applications encounter high-temperature conditions. Examples of such applications can be commonly found in the aerospace, power generation and hot metal working industries. LÄS MER

  5. 10. Light propagation and photonic functionalization of semi-ordered material (transparent wood)

    Författare :Adil Baitenov; Sergei Popov; Sergey Ponomarenko; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; light scattering; scattering material; hierarchical structure; FEM model; wood modification; random lasers; dye lasers; transparent wood; adsorption; diffusive media; Optics and Photonics; Optik och fotonik;

    Sammanfattning : Investigating novel materials requires understanding their chemical and optical properties, which allows for finding their uses through functionalization by chemical modification. In this thesis, we are focusing on a material with high anisotropic scattering - transparent wood. LÄS MER
