  1. 16. Aqueous behaviour of characteristic molecules in the synthesis of porous silica materials : - an atomistic description

    Författare :Emelie Nilsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; porous silica; struture directing agents; 29Si-NMR; neutron scattering; empirical potentail structure refinement; micelles;

    Sammanfattning : The formation process of porous silica materials is an intricate process, involving a number of components that interact to form a highly organized material. Both zeolites and mesoporous silica materials typically require the presence of organic structure director agents (SDAs) around which the silica network polymerizes. LÄS MER

  5. 19. Next generation tools for microbial cell factories

    Författare :Alister James Cumming; Daniel Daley; Neil Dixon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbial cell factories; Recombinant protein production; Bacteria; Plasmid; Genetic sensor; Inducible promoter; Genetic cassette; biokemi; Biochemistry;

    Sammanfattning : The bacterium E. coli is a popular choice for expressing recombinant proteins. It is easy to culture and many molecular tools for are available for directing protein production. When producing recombinant proteins, high yields and good quality soluble products are desirable. LÄS MER

  7. 20. Palladium Catalysis in Directed C-H Bond Activation and Cycloisomerisation Reactions

    Författare :Michael Oschmann; Jan-Erling Bäckvall; Oscar Verho; Jose Luis Mascareñas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Palladium II ; Catalysis; C-H Functionalisation; Transamidation; XAS; organisk kemi; Organic Chemistry;

    Sammanfattning : The main focus of this thesis concerns the development of Pd(II)-catalysed synthetic methodologies for the preparation of biologically active compounds.In the first part (paper I-III), unactivated C–H bonds of a cyclobutane derivative are selectively functionalised using a directing group starting from the feedstock compound verbenone (paper I).
