  1. 1. Application of ring statistics to characterise graphitisation of carbon fiber heat shields under atmospheric re-entry conditions

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Hamish Keay; [2023]
    Keywords : Aerospace; Heat shields; Re-entry; Graphitisation; Carbon fiber; Carbon phenolic; Ring statistics; Graph theory; Molecular Dynamics; återinträde; grafitisering; kolfiber; kolfenol; ringstatistik; grafteori; molekylär dynamik;

    Abstract : Carbon fibers submitted to high temperatures (>2000 °C) experience a permanent increasein their thermal conductivity. This change has been attributed to a change in the molecularstructure due to graphitisation. READ MORE

  2. 2. Methods and Potentials of Kraft Lignin Esterification

    University essay from KTH/Fiber- och polymerteknologi

    Author : Taoran Xu; [2023]
    Keywords : Kraft lignin; acetylation; fatty acid esterification; quantitative 31P NMR; lignin nanoparticles; Kraftlignin; acetylering; fettsyreesterifiering; kvantitativ 31P NMR; lignin nanopartiklar;

    Abstract : Lignin, en av huvudkomponenterna i lignocellulosabiomassa, utgör en stor mängd av sidoströmen från massaindustrin. Lignin är aromatiska makromolekyler som förekommer i rikliga mängder i naturen och uppvisar unika antioxidant-, uv-skyddande, anti-ultravioletta, antikorrosiva och antimikrobiella egenskaper, etc. READ MORE

  3. 3. Alkaline wet oxidation of biorefinery lignin from wheat straw

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Maja Lindblad; [2021]
    Keywords : alkaline wet oxidation; lignin oxidation; wheat straw; chemical pretreatment; biorefinery lignin; anaerobic digestion; response surface-modelling; chemical engineering; Technology and Engineering;

    Abstract : Climate change and depletion of fossil resources have generated a need for energy production based on renewable resources such as lignocellulosic biomass. Agricultural residues, like wheat straw, is lignocellulosic biomass that could contribute to the energy supply if it was used for biogas production. READ MORE

  4. 4. Development of magnetic lignin nanoparticles from low-molecular-weight eucalyptus and spruce lignin fractions

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Anna Wessén; Eliot Diklev; Lejla Al-Tamimi; [2020]
    Keywords : Magnetic nanoparticles; Hardwood; Softwood; Self-assembly; Lignin;

    Abstract : Lignin is one of the most common biopolymers in the world. Together with cellulose andhemicellulose it constitutes the fibers in the wood. It has a high molecular weight due to its complexstructure consisting of crossed-linked phenolic monomers and is concatenated with different types ofcarbon and ether bonds. READ MORE
