  2. 6. Design of carbide-based nanocomposite coatings

    Author : Erik Lewin; Ulf Jansson; Jörg Patscheider; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; chemistry; thin film; dc magnetron sputtering; carbide; nanocomposite; PVD; solid solution; Chemistry; Kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; Oorganisk kemi;

    Abstract : In this thesis research on synthesis, microstructure and properties of carbide-based coatings is reported. These coatings are electrically conducting, and can be tailored for high hardness, low friction and wear, along with load-adaptive behaviour. Tailoring these properties is achieved by controlling the relative phase content of the material. READ MORE

  4. 7. Glycoconjugates : Solid-phase synthesis and biological applications

    Author : Fredrik Wallner; Mikael Elofsson; Jan Kihlberg; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Glycoconjugate; Glycolipid; Solid-phase synthesis; Glycosylation; Gel-phase 19F-NMR spectroscopy; Fluorinated linker; Carbohydrat array; CD1; Organic chemistry; Organisk kemi;

    Abstract : Glycoconjugates are biologically important molecules with diverse functions. They consist of carbohydrates of varying size and complexity, attached to a non-sugar moiety as a lipid or a protein. Glycoconjugate structures are often very complex and their intricate biosynthetic pathways makes overexpression difficult. READ MORE

  5. 8. Phase Transformations in Solid Pharmaceutical Materials Studied by AFM, ESCA, DSC and SAXS

    Author : Denny Mahlin; Göran Alderborn; Sven Engström; Duncan Q M Craig; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; polymer; lipid; lactose; phase transformation; phase formation; crystallisation; AFM; X-ray diffraction; ESCA; DSC; solid dispersion; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

    Abstract : Mixing excipients is a common way to produce pharmaceutical materials with suitable properties for drug formulation. An understanding of the basic mechanisms involved in the formation and transformation of the structures of solid state mixtures is crucial if one is to be able to produce materials with the desired properties in a reliable way.

  6. 9. Kinetic Measurements Using Nanoplasmonic Sensing

    Author : Markus Schwind; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sn Nanoparticles; Sensing; Localized Surface Plasmon Resonances; Particle Plasmon; Metal Oxidation; Metal Corrosion; Solid-Liquid Phase Transition; Kinetics; Al Nanoparticles;

    Abstract : In this thesis the nanoplasmonic sensing technique was used to study kinetics of (i) the oxidation of Al nanoparticles in air and water and (ii) the solid-liquid phase transition in Sn nanoparticles. The nanoplasmonic sensing technique detects changes of the localized surface plasmon resonance (LSPR) in metal nanoparticles. READ MORE

  7. 10. Immobilization and Interaction of Biomolecules at the Solid-Liquid Interface : Applications to Solid-Phase Analytical Techniques

    Author : Ulf Jönsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein immobilization; silica; Immunoglobulins; Protein A; Fibronectin; chemical-vapour deposition; silane; ellipsometry; radiolabeling; contact-angle measurement; solid-phase analytical techniques;

    Abstract : The development of solid-phase-analytical techniques based on surface-concentration-measuring devices requires a stable and reproducible immobilization of biomolecules on well-characterized solid surfaces. This study reports on the immobilization of Immunoglobulin G, Protein A and Fibronectin on chemically modified silica surfaces. READ MORE
