  1. 16. Fracture characteristics of acetylated birch - Experimental and numerical studies

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Author : Gary Lai; Samuel Plönning; [2019]
    Keywords : acetylation; modification; birch; fracture mechanics; Technology and Engineering;

    Abstract : Modication of wood is carried out to increase the durability and dimensional stability of wood, and one of the modication methods is acetylation. Acetylation of wood means that polymers in the cell wall react with acetic anhydride. READ MORE

  3. 17. Finger-jointing of acetylated Scots pine using a conventional MUF resin

    University essay from KTH/Byggnadsmaterial

    Author : Christian Wincrantz; [2018]
    Keywords : Acetylated wood; Scots pine; juvenile wood; finger-jointing; mechanical properties modulus of rupture.;

    Abstract : Acetylation of wood is a modification technique that chemically alters the wood substance and enhances several properties of wood. The basic principle is to impregnate wood with acetic anhydride to react and replace OH-groups with acetyl groups in the wood cell wall. READ MORE

  5. 19. Estimating above ground biomass in a Salix plantation using high resolution UAV images

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Simon Nåfält; [2018]
    Keywords : biomass; Salix; structure from motion; unmanned aerial vehicle; allometry; point cloud; Earth and Environmental Sciences;

    Abstract : In forest biomass estimations, three dimensional (3D) canopy structure data derived from images captured by unmanned aerial vehicles (UAVs), also known as drones, has shown potential due to the flexibility and cost efficiency of the method. However, little research has been done for its applicability in bioenergy forest. READ MORE

  6. 20. Cellulosasyntesgener i två Populusarter : släktskap och uttrycksmönster under vedbildning

    University essay from SLU/Dept. of Forest Ecology and Management
