  1. 16. Viscoelasticity of transparent wood-polymer biocomposites : Measuring the time-dependence of a delignified birch and poly(methyl methacrylate) composite’s mechanical properties, using digital image correlation

    University essay from KTH/Materialvetenskap

    Author : Marine Jeanne Debouvry; [2023]
    Keywords : ;

    Abstract : The viscoelastic behavior of a delignified birch and poly(methyl methacrylate) (PMMA) composite was investigated, in an effort to learn more about the mechanical properties of transparent wood-polymer biocomposites. Tensile creep tests with constant load were performed for native wood, non-delignified, and delignified wood-polymer composites. READ MORE

  3. 17. A Study on Lignin or Zein Based Hydrophobic Coatings

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Filippa Wentz; Sandra Olofsson; [2023]
    Keywords : Lignin; Zein; Hydrophobic Coating; Dispersion; Chemical engineering; Technology and Engineering;

    Abstract : The two by-products lignin, from the paper industry, and zein, from starch production, have shown potential as hydrophobic barriers. Therefore, this study has aimed to produce and in-vestigate the hydrophobicity of lignin or zein dispersions coated on paper. READ MORE

  4. 18. Production, Purification, and Characterization of wood substrates and Galactose oxidase enzyme

    University essay from KTH/Industriell bioteknologi

    Author : Rakhesh Pongalikonnar Ranganathan; [2023]
    Keywords : Peracetic acid treatment; Galactose oxidase; Pichia pastoris; Biomass recalcitrance; Enzymatic upgrading; Perättiksyrabehandling; Galaktosoxidas; Pichia pastoris; Motsträvighet i biomassa; Enzymatisk uppgradering;

    Abstract : Trä är den bästa förnyelsebara källan för att producera många produkter på grund av dess biokompatibla och biologiskt nedbrytbara natur. Träets biomassa har en motstridig natur mot enzymatisk uppgradering. READ MORE

    Abstract : As our lives become more and more digital, our exposure to certain phenomena increases, one of which is hate speech. Thus, automatic hate speech identification is needed. READ MORE

  6. 20. Knock on wood - The relationship between macro variables and forest land return in Sweden 1996-2020

    University essay from Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Author : Julius Abelson; Per Liljered; [2022-02-15]
    Keywords : Forest Yield; Panel-data; Random Effects; Macro Viarables;

    Abstract : This thesis examines if three commonly used regions in Sweden differ in yearly forest yield over the period 1996-2020. An expression defining yearly forest yield is constructed and evaluated, together with macro economy determinants in a panel data model, using Random effects. READ MORE
