  1. 1. Fluids, Gels and Crystals : Phase behavior of binary thermoresponsive microgel mixtures

    Detta är en avhandling från Kemiska institutionen, Lunds universitet

    Författare :Jasper Immink; Lund University.; Lunds universitet.; [2019-03]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; colloidal phase behavior; microgel; binary mixture; colloidal gel; sequential gelation; patchy particle; binary crystal; crystal-to-crystal transition;

    Sammanfattning : Thermoresponsive colloidal microgels expel solvent from their interior upon crossing a threshold temperature, resulting in a significantly reduced size. The collapse of microgels can reversibly switch the interparticle interactions from soft repulsive to attractive, and the accompanying size reduction allows for precise control over volume fraction.

  2. 2. Modelling anisotropic interactions in colloidal systems

    Detta är en avhandling från Lund University, Faculty of Science, Department of Chemistry, Division of Physical Chemistry

    Författare :Alexei Abrikossov; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SIMULATION; Modelling; electrostatic interactions; Colloids; Statistical mechanics; SIMULATION; Modelling; electrostatic interactions; colloid; Statistical mechanics;

    Sammanfattning : There has been an increased interest to design “smart materials” which can self-assemble into complex structures in accordance to external factors such as for example electromagnetic fields. By designing particles with directional interactions one is able to control how particles will interact with each other. LÄS MER

  3. 3. Exactly Solvable Models for Self-Assembly

    Detta är en avhandling från Lund University, Faculty of Science, Department of Chemistry, Division of Physical Chemistry

    Författare :Erik Edlund; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The field of self-assembly studies the spontaneous formation of order from preexisting components.It holds the promise of fabricating tomorrows materials and devices not by traditional methods, but by designing building blocks that will act as supramolecular ``atoms'' and form the desired structures without external input.

  4. 4. Development of a Passive Immunization Strategy Against Atherosclerosis

    Detta är en avhandling från Department of Clinical Sciences, Lund University

    Författare :Alexandru Schiopu; Lund University.; Lunds universitet.; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; regression; plaque; peptide; oxidized LDL; immune system; carotid stenosis; cardiovascular diseases; apolipoprotein B-100; atherosclerosis; Kardiovaskulära systemet; Cardiovascular system; vascular injury; ultrasound; antibodies;

    Sammanfattning : Atherosclerosis is a chronic inflammatory disease, characterized by the accumulation of lipids and fibrous tissue in the wall of medium and large-sized arteries. The characteristic culprit of the disease is the atheroma, or atherosclerotic plaque, a patchy thickening of the arterial wall which affects the lumen, inducing various degrees of stenosis. LÄS MER

  5. 5. On the Phase Behaviour of Soft Matter: Understanding Complex Interactions via Quantitative Imaging

    Detta är en avhandling från Lund University, Faculty of Science, Department of Chemistry

    Författare :Maxime Bergman; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2019-02]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microgels; Lysozyme; eye lens proteins; confocal microscopy; interaction potential; phase behaviour; simulations;

    Sammanfattning : The effect of microscopic colloid interactions on the resultant macroscopic phase behaviour is a frequently studied topic in soft matter resarch, and lies at the heart of this thesis. Key structural and dynamic properties of colloidal model systems across liquid-solid transitions are tracked using optical imaging techniques. LÄS MER
