  1. 21. New Arylation Strategies Based on Organomain Group Reactivity

    Författare :Carina Sollert; Lukasz T. Pilarski; Brenton L. DeBoef; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; C-H functionalisation; catalysis; ruthenium; indole; silylation; boronate; boryl aryne; aryne distortion; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Sammanfattning : The work in this thesis describes the development of new heteroarylation methodology based on transition metal-catalysed C-H functionalisation and the properties of organomain group compounds. The underlying reaction mechanisms and reactivity patterns of the (hetero)arene substrates are also investigated. LÄS MER

  3. 22. Strength analysis and modeling of hybrid composite-aluminum aircraft structures

    Författare :Zlatan Kapidzic; Larsgunnar Nilsson; Per Gradin; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The current trend in aircraft design is to increase the proportion of fiber composites in the structures. Since many primary parts also are constructed using metals, the number of hybrid metal-composite structures is increasing. LÄS MER

  4. 23. Process chain simulation of forming, welding and heat treatment of Alloy 718

    Författare :Joachim Steffenburg-Nordenström; Lars-Erik Svensson; Lars-Erik Lindgren; Fredrik Niklasson; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forming; Welding; Stress relieve annealing; Heat treatment; Finite Element Simulation; Manufacturing process chain; Alloy 718; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Manufacturing of aero engine components requires attention to residual stress and final shape of the product in order to meet high quality product standards.This sets very high demands on involved manufacturing steps to meet design requirements. LÄS MER

  5. 24. Mercury-induced autoimmunity : Genetics and immunoregulation

    Författare :Monika Hansson; Manuchehr Abedi-Valugerdi; Marita Troye-Blomberg; Lucette Pelletier; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mercury; autoimmunity; collagen-induced arthritis; Th1 Th2; silver; tight-skin 1 mice; Immunology; Immunologi;

    Sammanfattning : The existence of immune self-tolerance allows the immune system to mount responses against infectious agents, but not against self-molecular constitutes. Although self-tolerance is a robust phenomenon, in some individuals as well as in experimental models, the self-tolerance breaks down and as a result, a self-destructive autoimmune disease emerges.

  7. 25. Supported Palladium Nanoparticles for Sustainable Cross-Coupling and Oxidation Reactions

    Författare :Vlad Pascanu; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The work presented in this thesis aims to combine the rich chemistry ofpalladium and the benefits of heterogeneous catalysis with metal-organic frameworks(MOFs) in developing robust materials that are recyclable and adaptable to operationunder a continuous flow regime.Two new catalysts were created based on palladium nanoparticles in themesoporous MOFs MIL-101 and MIL-88B.
