  1. 1. Versatile Association Behavior in Mixtures of Oppositely Charged Amphiphiles : From DNA-Like Assembly of Supramolecular Helices to Coacervation in Chiral Surfactant Systems

    Författare :Guanqun Du; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bile salts; Block copolymers; Oppositely charged polymer-surfactant systems; Co-assembly; BS sequestrants; Gemini surfactants; Supramolecular helices; Hexagonal packing; Chirality; Thermoresponsive behavior; Scattering; Tomography; Calorimetry;

    Sammanfattning : As biological surfactants, bile salts (BSs), play important roles in biological processes, i.e., food digestion, but also in BS-related diseases, as well as in applications. LÄS MER

  3. 2. Internal erosion in embankment dams : fluid flow through and deformation of porous media

    Författare :J. Gunnar I. Hellström; Thanasis D. Papathanasiou; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : A basic understanding of fluid flow through a porous media facilitates a comprehensive understanding of internal erosion in embankment dams. Hence, it is necessary to reveal the detailed seepage flow, the flow-induced forces acting within the porous media and the fluid flow deformation of the porous media. LÄS MER

  4. 3. Molecular Modeling of Cardiolipin

    Författare :Martin Dahlberg; Arnold Maliniak; Richard W. Pastor; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Biological membranes are assembled from many different lipids. Our understanding of membrane function and morphology is dependent on linking the properties of the lipids to the properties of the membranes. LÄS MER

  5. 4. Design and characterization of nanoparticles and their assemblies : Transmission electron microscopy investigations from atomic to mesoscopic length scales

    Författare :Arnaud Mayence; Lennart Bergström; Liberato Manna; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; electron microscopy; Materials Chemistry; materialkemi;

    Sammanfattning : Transmission electron microscopy (TEM) is a powerful and versatile tool for investigating nanomaterials. In this thesis, various transmission electron microscopy techniques are used to study the chemical and structural features of different types of inorganic nanoparticles of well-defined morphologies as well as their assemblies.

  7. 5. Hydrophobic surfaces: Effect of surface structure on wetting and interaction forces

    Författare :Petra M Hansson; Per M. Claesson; Agne Swerin; Adam C Simonsen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrophobic surface; superhydrophobic surface; atomic force microscopy; surface forces; capillary forces; cavitaion; surface roughness; friction; wetting; confocal Raman; contact angles; surface preparation; Langmuir-Blodgett;

    Sammanfattning : The use of hydrophobic surfaces is important for many processes both in nature and industry. Interactions between hydrophobic species play a key role in industrial applications such as water-cleaning procedures and pitch control during papermaking but they also give information on how to design surfaces like hydrophobic mineral pigments.
