  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. Human Exposure to Per- and Polyfluoroalkyl : Substances through Fish Consumption

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Welmoed Nauta; [2023]
    Keywords : Per- and polyfluoroalkyl substances; Human exposure; Fish consumption; Glasbruket; Target analysis; Mass balance analysis;

    Abstract : Human exposure to per- and poly-fluoroalkyl substances (PFAS) occurs mainly through two pathways, inhalation and ingestion. Dietary exposure to persistent organic pollutants (POPs), including PFAS, is driven mainly by the consumption of foods of marine or terrestrial animal origin. READ MORE

  4. 18. Biobased Photocurable Resins for 3D-Printing of Self-Healable & Recyclable Thermosets

    University essay from KTH/Fiber- och polymerteknologi

    Author : Anna Gardell; Maria Aspenberg; Julia Aziz; [2022]
    Keywords : vanillin; vitrimer; imine; resin; dynamic covalent bonds; biobased thermoset; photocuring; chemical recyclability; self-healing; digital light processing DLP ; 3D-printing; vanillin; vitrimer; imin; resin; dynamiska kovalenta bindningar; biobaserad härdplast; fotohärdning; kemisk återvinningsbarhet; självläkning; digital light processing DLP ; 3D-utskrift;

    Abstract : Överkonsumtionen av engångsartiklar i fossilbaserad plast är ett av dagens stora miljöproblem. Således finns en efterfrågan på strategier för framställning av biobaserade plaster i allmänhet och härdplaster i synnerhet. READ MORE

  5. 19. Reinforced Biodegradable Polymer Composite Material based on Japanese Washi Paper

    University essay from Uppsala universitet/Institutionen för kemi - Ångström

    Author : Lovisa Rova; [2022]
    Keywords : biodegradable; polymer; composite; paper-based; washi; poly butylene succinate ; biodegradation;

    Abstract : In this study, traditional Japanese washi paper was sandwiched with poly(butylene succinate)(PBS) in order to produce a paper-based composite material that can be biologically degraded. Specimens were prepared using a hot press, and the mechanical properties of the washi paperand the new composite material were investigated by tensile tests. READ MORE

  6. 20. Modeling of Low-Energy Neutron Scattering in Liquid Hydrogen Using NCrystal

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/Kärnfysik

    Author : Tim Günter; [2022]
    Keywords : ESS; European Spallation Source; neutron; scattering; moderator; liquid hydrogen; modeling; ncrystal; njoy; Physics and Astronomy;

    Abstract : The European Spallation Source ESS, under construction in Lund, Sweden, aims to produce high-brightness and intensity neutrons for a multitude of experiments upon completion. An efficient production of neutrons requires elaborate understanding of the moderation process which slows the neutrons from relativistic speed to a kinetic energy of meV. READ MORE
