  1. 11. Lignin Biorefining: Swelling and activation of fibers for lignin extraction

    University essay from KTH/Fiber- och polymerteknologi

    Author : Ali Al Husseinat; [2023]
    Keywords : Biorefining; Carboxymethylation; Extraction; Lignin; Swelling; Bioraffinering; Extraktion; Karboxymetylering; Lignin; Svällning;

    Abstract : I världens omvandling mot en bioekonomi kommer lignocellulosa material spela en stor roll i ersättningen av fossila resurser. Lignin är den mest tillgängliga källan av förnybara och naturligt förekommande aromatiska ämne och den utgör 15–30% av ved. READ MORE

  3. 12. Petrography of impactites from the Dellen impact structure, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Robert Mroczek; [2023]
    Keywords : Dellen; Impact; structure; magnetite; apatite; shock waves; shock-metamorphic; features; Impactite; petrography; scanning electron microscope; SEM; geology; Earth and Environmental Sciences;

    Abstract : Identification and characterization of shock-metamorphic features in hypervelocity impact craters is important for our understanding of how shock waves interact with geologic materials and how impact craters form, which in turn is essential to our understanding of what role impact cratering played in the development of our solar system. Of particular interest are accessory minerals like apatite, which contains various volatiles that can affect the atmosphere of a body, or magnetite whose magnetic properties constitute a remote sensing indicator which allows us to study and understand the internal structures of distant bodies.

  4. 13. Motion of icy grains originating in Saturn’s D-ring

    University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen; Uppsala universitet/Institutionen för fysik och astronomi

    Author : Apostolos Kolokotronis; [2023]
    Keywords : ;

    Abstract : Saturn's rings have long been thought to provide the planetary atmosphere with infalling material, affecting both its chemical composition and physical properties (e.g. temperature). READ MORE

  5. 14. The Magnetocaloric Effect in Antiferromagnetic and Noncollinear Magnets

    University essay from Uppsala universitet/Materialteori

    Author : Siri Alva Berge; [2023]
    Keywords : magnetocaloric effect; atomistic spin dynamics; monte carlo; antiferromagnet; neodymium; noncollinear magnetism;

    Abstract : The magnetocaloric effect (MCE) is the temperature change in a magnetic material due to a change in an applied magnetic field. How the MCE behaves in different magnetic materials and at different phase transitions is fundamental to understand. READ MORE

  6. 15. Quantitative susceptibility mapping of the knee: A comparison of approaches for addressing fatty tissue

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Cornelia Säll; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Background/purpose Quantitative susceptibility mapping (QSM) is an MRI-based post processing technique to evaluate the magnetic susceptibility, χ, of human tissue using phase data. While brain imaging has been the most common application, other areas have also raised interest. READ MORE
