  1. 1. Surface Force and Friction effects of adsorbed layers and surface topography

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Xiaoyan Liu; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction; nanotribology; surface forces; diblock copolymer; lipid; QCM-D; AFM; optical reflectometry; neutron reflectivity; X-ray reflectivity; micro-patterned surface; Kemi; Chemistry;

    Abstract : Interfacial features of polymers are a complex, fascinating topic, and industrially very important. There is clearly a need to understand interactions between polymer layers as they can be used for controlling surface properties, colloidal stability and lubrication. The aim of my Ph. READ MORE

  2. 2. Controlling DNA compaction and the interaction with model biomembranes

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Marie-Louise Ainalem; Lunds universitet.; Lund University.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; model biomembrane; DNA compaction; cryo-TEM; null ellipsometry; dynamic light scattering; toroid; bilayer; neutron reflectivity; dendrimer; PAMAM; DNA; poly amido amine ;

    Abstract : The studies described in this thesis forms part of a larger collaborative project, Neonuclei, with the objective to design a module for packaging the negatively charged DNA into a ”neonucleus” with transcription competence. There are many applications that require control of DNA compaction, i.e. packaging or condensation. READ MORE

  3. 3. Interfacial Properties of Lipid Liquid Crystalline Nanoparticles

    University dissertation from Lund University

    Author : Pauline Vandoolaeghe; Lunds universitet.; Lund University.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; interaction; adsorption; surface; peptide; bilayer; cubic phase; monoolein; cubosome; lipid; liquid crystalline nanoparticles; ellipsometry; neutron reflectivity; QCM-D; SAXD;

    Abstract : Lipid liquid crystalline nanoparticles are studied for their potential as biocompatible carriers for pharmaceutical, food and cosmetic applications. Their potential as delivery vehicles is due to their nanometer size, their controllable structure and physical properties and their large carrying capacity of a wide range of molecules. READ MORE

  4. 4. A Structural Viewpoint of Magnetism in Fe and Co Based Superlattices

    University dissertation from Uppsala : Acta Universitatis Upsaliensis
