  1. 6. Investigation of robustness of a SiC MOMS pressure sensor in high pressure/temperature operation conditions

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Monika Sieczka; [2022]
    Nyckelord :;

    Sammanfattning : Rigorous environmental policies and the need for higher fuel economy continuously demand new innovations in the combustion process of automotive engines. Consequently, there is an increasing necessity for active monitoring of the combustion event, and therefore, microsystems have started coming into play. LÄS MER

  2. 7. Improvement of Pt-based catalyst supported on CeZrO2 used for the high-temperature water-gas shift reaction

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Milda Grikainyte; [2022]
    Nyckelord :Water-gas shift; catalyst; chemical engineering; Chemistry;

    Sammanfattning : The iron-chromium (Fe/Cr) catalyst is used for high-temperature water-gas shift (HT WGS) reaction. A major concern using the Fe/Cr catalyst is that it contains hexavalent chromium (Cr+6) which is a potent carcinogen causing health and environmental issues. LÄS MER

  3. 8. UV Curable Polymers for use in Additively Manufactured Energetic Materials

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Alexis Delorme; [2022]
    Nyckelord :Additive manufacturing; 3D printing; UV curing; mechanical properties; solid rocket motor; propellant; polymers; depth of cure; Additiv tillverkning; 3D-utskrift; UV-härdning; mekaniska egenskaper; fast-bränsleraketmotor; drivmedel; polymerer; härdningsdjup;

    Sammanfattning : Fast-bränsle-raketer (SRM) har funnit sin plats i en stor mängd tillämpningar sedan deras framkomst mer än 2000 år sedan. En SRMs prestanda är förutbestämd av geometrin av drivmedelskrutet och är begränsad av gjutningsmetoden, som idag främst används i produktion. LÄS MER

  4. 9. Oligosaccharide Analysis - Assessment of the DNS Method and Specification of Glucans Processed with CGTase

    Master-uppsats, Lunds universitet/Bioteknik; Lunds universitet/Bioteknik (master)

    Författare :Matilda Johansson; [2022]
    Nyckelord :CGTase; DNS; Chromatography; HPAEC; HPAE; Carbohydrate; Carbohydrates; Glucans; Cyclodextrin glycosyltransferase; Biotechnology; Bioteknik; Flory; Enza; Enzyme; Technology and Engineering;

    Sammanfattning : In this study, the reagent 3,5-dinitrosalicylic acid (DNS) and high-performance anion exchange chromatography (HPAEC) were used for carbohydrate characterisation. It was revealed that the DNS reaction is not exclusive to reducing ends as commonly thought, but rather that the reagent reacts with other parts of the carbohydrate molecules as well. LÄS MER

  5. 10. A comparison of pressurised cylinders in HIP systems using CFD and FEM

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Lisa Lindqvist; [2021]
    Nyckelord :Hot isostatic pressing; HIP; Pressure vessel; Monoblock; Axisymmetric; FSI;

    Sammanfattning : A hot isostatic press (HIP) is a system which utilises high temperatures and pressure in order to densifyand enhance the material properties of components in the aerospace, automotive and additive manufacturingindustries, to mention a few. Quintus is a world leading manufacturer of HIP systems, and this master’s thesiswork has been written in collaboration with them. LÄS MER
