  1. 6. Decellularized ECM derived collagen bioinks

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för cell- och molekylärbiologi

    Författare :Matilda Carlson; [2023]
    Nyckelord :;

    Sammanfattning : 3D bioprinting allows for the manufacturing of tissue-like structures that could be used for culturing and studying cells in a microenvironment representative of the cell’s natural environment. In recent years, hydrogel bioinks from different biomaterials have been in development and utilized in tissue engineering applications. LÄS MER

  3. 7. Experimental study on the effect of rocket nozzle wall materials on the stability of methane

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Thomas L. Holmboe; [2023]
    Nyckelord :Methane; pyrolysis; catalysis; nickel; coke deposition; chemical modelling; GRI3.0; rocket nozzle; regenerative cooling;

    Sammanfattning : There has recently been an increased interest in methane as a rocket propellant due to its physical properties as well as the possibility of in-situ resource utilization in places like Mars. As part of ESA’s Future Launcher Preparatory Program, KTH in cooperation with GKN Aerospace has started the MERiT program, which seeks to study the characteristics of methane under conditions found in rocket nozzle cooling channels.

  4. 8. ROP in novel biobased ionic liquids towards cellulose functionalization

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Rebecca Mattsson; [2023]
    Nyckelord :Ionic liquids; SI-ROP; coROP; polyesters; cellulose; Jonvätska; yt-initierad Ringöppnings-polymerisation; ringöppnings-sampolymerisation; polyestrar; cellulosa;

    Sammanfattning : Ett nytt sätt att aktivera cellulosa för kemisk modifiering med hjälp av en miljövänlig process har utvecklats innan starten av detta projekt. Två versionen av den nyskapade betain-baserade jonvätskan, BBIL har syntetiserats, en som använder mesylat som motjon, M-BBIL och en som använder acetat, A-BBIL. LÄS MER

  5. 9. Moisture Transport in PA6

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Emanuel Markström; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Polyamide 6 (PA6) is known to absorb water from its environment due to its chemical structure. The water absorption leads to changes in the mechanical properties as well as an increase in volume (swelling) of the polyamide. LÄS MER

  7. 10. Thermal Initiation of Energetic Materials Caused by Hot Fragments

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Sirak Ghebreamlak; [2022]
    Nyckelord :Applied mathematics; computational mathematics; heat equation; thermal initiation; chemical kinetics; energetic materials; Tillämpad matematik; beräkningsteknik; värmeledningsekvationen; termisk initiering; kinetik; energetiska material;

    Sammanfattning : The cause of unintentional initiations of energetic materials is an important area of study due to the risks that comes with storing energetic materials such as high explosives. The current models used to simulate the process of heating energetic materials by a hot metal fragment do not give reliable predictions. LÄS MER
