  2. 1. Biomolecular interactions at model interfaces : a self-assembled monolayer approach

    Author : Sofia Svedhem; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The overall aim of this thesis has been to explore the use of self-assembled monolayers (SAMs) in model studies of biomolecular binding at interfaces. Molecular details of interfaces are difficult to address experimentally, and in spite of the fact that interactions in the living system commonly occur at interfaces, e.g. READ MORE

  4. 2. Self-organization of nanoparticles - implications for interface biology

    Author : Anders Lundgren; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gold nanoparticles; self-organization; self-assembly; nanostructure; nanopatterns; cell surface interactions; chemical gradients;

    Abstract : Cells bind to their surroundings via proteins displayed on the cell surface. These interactions support the cells and are important for many cellular processes, e.g. cell migration during morphogenesis, wound healing and cancer metastasis. READ MORE

  5. 3. Characterization of Self-Assembled Monolayers of Oligo(phenyleneethynylene) Derivatives on Gold

    Author : Somsakul Watcharinyanon; Lars Johannson; Ellen Moons; Stacey Sorensen; Karlstads universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Following nanoparticle self-assembly in real-time : Small-angle X-ray scattering and quartz crystal microbalance study of self-assembling iron oxide nanocubes

    Author : Martin Kapuscinski; Lennart Bergström; Niklas Hedin; Andrei Petukhov; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; self-assembly; mesocrystal; time-resolved; small-angle X-ray scattering; iron oxide nanocubes; QCM-D; Materials Chemistry; materialkemi;

    Abstract : Self-assembly of nanoparticles is a widely used technique to produce nanostructured materials with crystallographic coherence on the atomic scale, i.e. mesocrystals, which can display useful collective properties. This thesis focusses on the underlying mechanism and dynamics of mesocrystal formation by using real-time techniques. READ MORE

  7. 5. Electro-Interfacial Composition Control by Ionic Liquid Technology : Nanostructure, Self-Assembly, and Friction

    Author : Sichao Li; Mark W. Rutland; Sergei Glavatskih; Nicholas Spencer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ionic liquids; electrical double layer; self-assembly; electro-interfacial structure; tribotronics; supercapacitors; friction; lubrication; Jonvätskor; elektriskt dubbelskikt; självassociering; gränsskiktselektrostruktur; tribotronik; superkondensatorer; friktion; smörjning; Kemi; Chemistry;

    Abstract : Given the potential of ionic liquids (ILs) for batteries, supercapacitors and advanced lubricants, it is crucial to understand how electric fields affect the interfacial behaviour in IL-solvent systems and the intricate relationship between nanostructure and tribotronic properties. This thesis investigates the structural and compositional changes of ILs with different solvents at electrified interfaces. READ MORE
