    Författare :Somsakul Watcharinyanon; Lars Johannson; Ellen Moons; Stacey Sorensen; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-assembled monolayers; Oligo phenyleneethynylene ; high-resolution X-ray photoemission spectroscopy HRXPS ; near-edge X-ray absorption fine structure spectroscopy NEXAFS ; Material physics with surface physics; Materialfysik med ytfysik; Physics; Fysik;

    Sammanfattning : Oligo(phenyleneethynylene) (OPE) molecules are a class of fully conjugated aromatic molecules, that attract attention for their application as “molecular wires” in molecular electronic devices. In this thesis work, self-assembled monolayers (SAMs) formed from a variety of OPE derivatives have been studied. LÄS MER

  4. 3. Nucleic acid in gene delivery and gene regulation

    Författare :Pedro Moreno; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The concept of gene therapy, initially attributed to a technology that would allow the correction of inherited genetic disease, has evolved over the years. The realization of the immense technical hurdles to achieve genetic correction led to a broadening of the concept now including the transfer of genetic material whose expression will counteract, mitigate or revert a disease phenotype.

  5. 4. Strategies for building polymers from renewable sources : Using prepolymers from steam treatment of wood and monomers from fermentation of agricultural products

    Författare :Margaretha Söderqvist Lindblad; KTH; []
    Nyckelord :renewable sources; biodegradable polymers; hemicellulose; 2-hydroxyethyl methacrylate; modification of hemicellulose; methacrylation reaction; rheology measurements; dynamic-mechanical behavior; 1; 3-propanediol; 1; 4-cyclohexanedimethanol; succinic ac;

    Sammanfattning : A strategic research area today is development of polymericproducts made from renewable sources. The ways of utilizingrenewable sources studied in this thesis are using 1)prepolymers obtained by steam treatment of wood and 2) monomersobtainable by fermentation of agricultural products. LÄS MER

  7. 5. Therapeutic Cancer Vaccines Targeting Molecules Associated with Tumor Angiogenesis

    Författare :Julia Femel; Anna-Karin Olsson; Grietje (Ingrid) Molema; Uppsala universitet; []

    Sammanfattning : Induction of an endogenous antibody response by therapeutic vaccination could provide an alternative to cost-intensive monoclonal antibody-based treatments for cancer. Since the target of a cancer vaccine will most likely be a self-antigen, self-tolerance of the immune system must be circumvented. LÄS MER
