  1. 1. Evaluation of the Tactoid Formation in Clay Systems

    Författare :Maria Jansson; Teoretisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lera; Montmorillonit; Nano-plattor; Taktoider; Anisotropi; Grov korninga modeller; MD simuleringar; MC simuleringar; SAXS; Svälltryck; Clay; Montmorillonite; Nanoplatelets; Tactoid; Anisotropy; Coarse-grained models; MD simulations; MC simulations; SAXS; Swelling pressure;

    Sammanfattning : Clay minerals consist of anisotropic nanoplatelets where the majority of the clay minerals are highly charged, and thus, swell in aqueous solution. The structure and swelling depend on the type of clay mineral, and also on the ionic composition, and temperature. LÄS MER

  2. 2. Synchrotron X-ray Scattering and Monte Carlo Simulations of Structure and Forces in Silicate Nanoplatelet Dispersions

    Författare :Mo Segad; Teoretisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAXS; MC simulations; Swelling; Tactoids; EXAFS; DLS; Cryo-TEM; Nanoplatelets; MX80; Na Ca montmorillonite.;

    Sammanfattning : Clays are the world’s most widely used natural material, however, little is known regarding the microstructure as well as the forces involved in clay-water interactions, and their influence on the swelling properties. The utilization of clay platelets is nowadays a key in a number of biological and industrial applications e.g. LÄS MER

  3. 3. Swelling and Microstructure of Nanoplatelet Systems

    Författare :Axel Thuresson; Teoretisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nanoplatelets; Model clay system; Coarse grained models; Statistical mechanics; MC simulations; MD simulations; SAXS; Cryo-TEM; Laponite; Montmorillonite; Swelling; Tactoid;

    Sammanfattning : Many clay minerals consist of charged nanoplatelets that swell in an aqueous solution. The swelling and the microstructure depend on the type of clay mineral but are also dependent on, for example, the ionic composition and the temperature of the solution. LÄS MER

  4. 4. Electrostatically Driven Structure Formation in Clay Dispersions

    Författare :Maria Jansson; Teoretisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lera; Montmorillonit; Laponite®; Taktoid; Anisotropi; Överladdning; Interkalering; Grov korninga modeller; MD simuleringar; MC simuleringar; SAXS; Svälltryck; zeta-potential; Clay; Montmorillonite; Laponite®; Nanoplatelets; Tactoid; Anisotropy; Overcharging; Intercalation; Coarse-grained modeling; MD simulations; MC simulations; SAXS; Swelling pressure; zeta-potential;

    Sammanfattning : Clay minerals consist of clay platelets, which are anisotropic in both size and charge, and these can form a lamellar structure depending on the size, making it a seemingly perfect model system for an electrical double layer. The situation is however, from a structural point, slightly less ideal. LÄS MER

  5. 5. Manufacturing and Characterization of Filled Polymeric Systems

    Författare :Henrik Oxfall; Chalmers University of Technology; []
    Nyckelord :PS; hybrid composites; EBA; computer simulations; graphene; rheology; mould filling; graphite nanoplatelets; powder injection moulding; electrical conductivity; elongational flow; thermal properties; jetting;

    Sammanfattning : The physical properties are changed if fillers are added to a polymeric material. In this work a highly filled model system for power injection moulding (PIM) and graphite nanoplatelet (GNP) based nanocomposites have been manufactured and characterized. LÄS MER
