  2. 11. Crystallization on the Mesoscale : Self-Assembly of Iron Oxide Nanocubes into Mesocrystals

    Author : Michael Agthe; Lennart Bergström; German Salazar-Alvarez; Tommy Nylander; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Self-assembly; iron oxide nanocubes; mesocrystal; small angle X-ray scattering; video microscopy; QCM-D; Materials Chemistry; materialkemi;

    Abstract : Self-assembly of nanoparticles is a promising route to form complex, nanostructured materials with functional properties. Nanoparticle assemblies characterized by a crystallographic alignment of the nanoparticles on the atomic scale, i.e. mesocrystals, are commonly found in nature with outstanding functional and mechanical properties.

  4. 12. Polymorphism and Crystallization of p-Aminobenzoic Acid

    Author : Sandra Gracin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; controlled crystallization; polymorphism; p-aminobenzoic acid;

    Abstract : Polymorphs are solid phases where the chemical composition isequal but the crystal structure differs. Many organic compoundsmay appear in more than one crystalline structure. READ MORE

  5. 13. Crystallization and Differentiation Processes in the Thin Layered Alkali Gabbroic Intrusions of the Ulvö Gabbro Complex, Central Sweden

    Author : Johan Hogmalm; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; layered intrusion; fractional crystallization; modal layering; in situ crystallization; Ulvö; saucer-shaped sill; post-cumulus; LA ICP-MS;

    Abstract : Fractional crystallization of magma is a commonly invoked mechanism for chemical differentiation in systems that range from volcanoes to entire planets. However, the processes that control separation of crystals and liquids in natural systems remain controversial, since the dynamics of crystallizing magma chambers cannot be studied directly.
