  1. 19. Keynote 9 - Neutron spin echo spectroscopy as a sensitive tool to study membrane elasticity in microemulsions and lipid membranes
    Dr Olaf Holderer (Julich Center for Neutron Scattering at MLZ, Garching, Germany)

    The high energy resolution of Neutron Spin Echo (NSE) Spectroscopy is perfectly suited for studying thermally driven membrane fluctuations in soft matter systems. Measuring membrane fluctuations allows determining the membrane bare bending rigidity of a membrane patch and is complementary to phase diagram measurements and SANS [1]. Adding co-surfactants such as diblock copolymers or...

  2. 20. Contr. Talk 9 - On the kinetic stability of non-ionic surfactant vesicles.
    Ulf Olsson (Lund University)

    Surfactant/lipid vesicles are closed bilayer aggregates that are interesting to understand because of their importance in several biological processes. They are often surprisingly stable, partly because of an intriguing stability against Ostwald ripening. If, in addition, fusion events are rare, a vesicle dispersion may retain its size distribution for weeks and months. For this reason,...

  3. 21. Keynote 10 - Hydrostatic Pressure Effects on the Structure and Stability of Lipid Membranes
    Prof. John Seddon (Imperial College, London, UK)
    13/09/2018, 16:20

    We have studied the effects of pressure on the gel-fluid transition in sphingomyelin bilayer membranes, and have found that the ordering of the chains and the development of the ripples on forming the gel phase occur on different timescales.
    We have demonstrated by x-ray diffraction that fluid-fluid phase separation in ternary DOPC / DPPC / cholesterol mixtures can be induced in bulk phases by...
