  1. 1. 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

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Marine Jeanne Debouvry; [2023]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

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

    Sammanfattning : 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. LÄS MER

  4. 3. Elemental variability in tree-rings as indicator for climate change : a case study on beech and oak trees at the Laacher See, Germany

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Ann-Kathrin Wild; [2022]
    Nyckelord :trace elements; tree-rings; dendrochemistry; dendroclimatology; ITRAX; Laacher See; mofettes; tree-bark; Quercus sp.; Fagus sp.;

    Sammanfattning : The aim of this study was to contribute to the comprehension of the connection of element uptake in trees at the Laacher See in Germany and climatic parameters on different time scales. Understanding the relationship of certain elements in trees and temperature might enable the assignment of extraordinary high peaks in the elemental concentration, which cannot be explained by temperature, to another process as CO2 degassing of the mofettes, which are relics of the volcanic past of the lake.

  5. 4. Rumen metabolism and digestibility in dairy cows offered diets with forest by-products

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Muhammad Irfan; [2022]
    Nyckelord :Dairy cows; Wood by-products; Rumen digestibility; Metabolism; Aspen tree;

    Sammanfattning : Swedish dairy industry faced a cris i s of feed shortage in summer of 2018, followed by a dry autumn. The forage shortage was severe in some regions. During that period Swedish g overnment intervened by introducing a 1. LÄS MER

  7. 5. Process simulation of HMF production from wheat bran and sugar beet pulp

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Matilda Petersson; [2021]
    Nyckelord :5-hydroxymethylfurfural; Wheat bran; Sugar beet pulp; Process simulation; Aspen Plus; Biorefinery; Chemical engineering; Technology and Engineering;

    Sammanfattning : Due to the progressing environmental problems related to global warming, the chemical industry is transitioning from fossil to renewable feedstocks. For added environmental benefits, surplus biomass from the agricultural industry which currently does not have any high-value applications can be used for production of chemicals. LÄS MER
