  1. 1. Self-assembly of magnetic particles

    Författare :Hauke Carstensen; Max Wolff; Vassilios Kapaklis; Björgvin Hjörvarsson; Benjamin Yellen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; self-assembly; tunable interactions; phase transition; ferrofluid; Fysik; Physics;

    Sammanfattning : Self-assembly is the spontaneous formation of larger structures from small building blocks. This process is driven and determined by the interactions between the constituents. LÄS MER

  3. 2. Spectral Methods for Self-Assembly

    Författare :Erik Edlund; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; classical spin models; patterns; isotropic interactions; colloids; Self-assembly;

    Sammanfattning : Conventional manufacturing relies on robotics and chemistry to create, shape and combine components into products. Nature shows us an alternative route: by carefully designing interactions between components, they can be made to spontaneously self-assemble into complex arrangements. LÄS MER

  4. 3. Electro-Interfacial Composition Control by Ionic Liquid Technology : Nanostructure, Self-Assembly, and Friction

    Författare :Sichao Li; Mark W. Rutland; Sergei Glavatskih; Nicholas Spencer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ionic liquids; electrical double layer; self-assembly; electro-interfacial structure; tribotronics; supercapacitors; friction; lubrication; Jonvätskor; elektriskt dubbelskikt; självassociering; gränsskiktselektrostruktur; tribotronik; superkondensatorer; friktion; smörjning; Kemi; Chemistry;

    Sammanfattning : Given the potential of ionic liquids (ILs) for batteries, supercapacitors and advanced lubricants, it is crucial to understand how electric fields affect the interfacial behaviour in IL-solvent systems and the intricate relationship between nanostructure and tribotronic properties. This thesis investigates the structural and compositional changes of ILs with different solvents at electrified interfaces. LÄS MER

  5. 4. Following nanoparticle self-assembly in real-time : Small-angle X-ray scattering and quartz crystal microbalance study of self-assembling iron oxide nanocubes

    Författare :Martin Kapuscinski; Lennart Bergström; Niklas Hedin; Andrei Petukhov; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; self-assembly; mesocrystal; time-resolved; small-angle X-ray scattering; iron oxide nanocubes; QCM-D; Materials Chemistry; materialkemi;

    Sammanfattning : Self-assembly of nanoparticles is a widely used technique to produce nanostructured materials with crystallographic coherence on the atomic scale, i.e. mesocrystals, which can display useful collective properties. This thesis focusses on the underlying mechanism and dynamics of mesocrystal formation by using real-time techniques. LÄS MER

  7. 5. Structure formation at solid/liquid interfaces : Understanding self-assembly and environmental challenges

    Författare :Shirin Nouhi; Adrian R. Rennie; Vassilios Kapaklis; Maja S. Hellsing; Ann Terry; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solid liquid interface; neutron scattering; colloidal particles; self-assembly; perfluoroalkyl substance; Moringa seed proteins; adsorption; lamellar disorder; thermal fluctuations.;

    Sammanfattning : The work described in the present dissertation has explored the structure of particles and molecules at solid/liquid interfaces, aiming to understand the physics of self-organizing systems and use this knowledge to address some environmental issues. Surface-sensitive neutron scattering techniques, such as reflectometry and grazing incidence small angle scattering, have been used as the primary tool to investigate structures in proximity to an interface.
