    Författare :Sheng Xie; Mingdi Yan; Olof Ramström; Stefan Bräse; KTH; []
    Nyckelord :Click Chemistry; Dipolar Cycloaddition; Enamine; Triazoline; Amidine; Aggregation-induced emission; pure nanodrugs; aryl amide; thioacid azide reaction; nucleophilic aromatic substitution; azide-masked fluorophore; nitrene insertion; Kemi; Chemistry;

    Sammanfattning : The work centersaround perfluoroaryl azides (PFAAs), and theirability to undergo certain fast and robusttransformations. The chemistry was furtherappliedfor biomedical applications.The first section focuses on the azide-aldehyde-amine cycloaddition using PFAAs. LÄS MER

  2. 22. Novel Possibilities for Advanced Molecular Structure Design for Polymers and Networks

    Författare :Anna Finne; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ring-opening polymerization; coordination-insertion; germanium; cyclic tin alkoxides; spirocyclic initiators; poly L-lactide ; poly 1; 5-dioxepan-2-one ; triblock; star-shaped; network; functionalization; morphology; AFM; Polymer chemistry; Polymerkemi;

    Sammanfattning : Synthetic and degradable polymers are an attractive choicein many areas, since it is possible to control the way in whichthey are manufactured; more specifically, pathways tomanipulate the architecture, the mechanical properties and thedegradation times have been identified. In this work,L-lactide, 1,5-dioxepan-2-one and ε-caprolactone were usedas monomers to synthesize polymers with different architecturesby ring-opening polymerization. LÄS MER

  3. 23. Electronic Properties of Metal Oxide Films Studied by Core Level Spectroscopy

    Författare :Jan Hinnerk Richter; Anders Sandell; Håkan Rensmo; Anne Borg; Uppsala universitet; []
    Nyckelord :Physics; electron spectroscopy; metal oxide; chemical vapour deposition; ion insertion; metal organic; band alignment; zirconium; titanium; silicon; high k; Fysik;

    Sammanfattning : In this dissertation core level electron spectroscopy has been employed to study various aspects of metal oxide films grown under ultra-high vacuum conditions. Studies on in situ ion insertion of lithium into thin TiO2 systems were performed. LÄS MER

  4. 24. Insertion and Topology of Inner Membrane Proteins in Escherichia coli

    Författare :Annika Sääf; Tony Pugsley; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Sammanfattning : Integral membrane proteins are found in all cellular membranes and fulfil many of the functions that are central to life. They maintain the membrane structure, but are also involved in the regulation of different cellular processes. LÄS MER

  5. 25. Identification of novel antibiotic resistance genes through the exploration of mobile genetic elements

    Författare :Mohammad Razavi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Environment; Metagenomics; Antibiotic resistance; Mobile genetic elements; Insertion sequences; Integron; Resistome; Next-generation sequencing;

    Sammanfattning : Backgrounds and aims: The evolution of multi-resistant pathogens is seriously threatening our ability to provide modern healthcare. Many of the mobile resistance factors in clinics appear to originate from environmental bacteria. LÄS MER
