  2. 16. Nanostructured surfaces created by the interactions of dendrimers and oppositely charged amphiphiles

    Author : Marianna Yanez; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PAMAM; Surfactant; SDS; Lipid; Bilayer; Model Biomembrane; Nucleolipid; DLPA; DLPU; DNA; RNA; Neutron Reflectometry; Poly amidoamine ; Interface; Adsorption; Polyelectrolyte;

    Abstract : The research described in this thesis aims to understand the interactions between cationic poly(amidoamine) (PAMAM) dendrimers and small oppositely charged amphiphiles at the solid-liquid and air-liquid interfaces in relation to the bulk solution behavior. There is high interest in PAMAM dendrimers because they are well-defined polymers with a hierarchical architecture which makes them promising materials as nanocapsules and gene vectors. READ MORE

  4. 17. Redox Reactions of Uranium-Based Materials in Aqueous Systems and Under UHV Conditions. : Two models mimicking radiation-induced oxidation of spent nuclear fuel

    Author : Ghada El Jamal; Mats Jonsson; Christophe Jégou; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Abstract : The demand for clean electricity is a primary concern in Europe. Nuclear power isconsidered as a greenhouse gas-free technology for generation of electricity. However,compared to other energy sources, it generates a highly toxic waste.In Sweden, the long-term solution for the waste disposal issue is called the KBS-3 method. READ MORE

  5. 18. Interactions of Mucins with Biopolymers and Drug Delivery Particles

    Author : Olof Svensson; Malmö högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mucin; chitosan; lactoperoxidase; multilayer; mucoadhesion; nanoparticles; ellipsometry;

    Abstract : The main components in the mucous gels apart from water are mucins, which are proteins with high molecular weights and an abundance of negatively charged oligosaccharide side chains. The aim of the investigations was to characterize interactions between mucins and other proteins that are present in the mucous gel, and also between mucins and components used in pharmaceutical formulations.

  6. 19. Molecular Adsorption on Self Assembled Monolayers studied by Surface Acoustic Waves and Infrared Spectroscopy

    Author : Lars Bertilsson; Antonio J. Ricco; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Chemical sensors based on the selective absorption of gas/vapors in polymer layers rely on molecular interactions. Details of the mechanisms involved can be obtained by studying the adsorption on well defined model organic surfaces. READ MORE

  7. 20. Physical Properties and Structural stability of carbon nanotubes under extreme conditions

    Author : Maxime Noël; Roberts Joffe; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics; Physics; Fysik;

    Abstract : Carbon nanotubes (CNTs) have attracted an immense attention of the research community since reporting on this system by S. Ijima in 1991. A "single-walled" CNT (SWCNT) can be considered as a rolled-up single-layer graphene - a one atom-thick layer of carbon atoms arranged in a hexagonal lattice. READ MORE
