8. Keynote 11 - Development of µRheoSANS and Investigating the Structure and Rheology of Complex Fluids at High Shear Rate

We are developing slit rheometers compatible with simultaneous small angle neutron scattering (SANS) measurements to directly correlate structure and rheology over a broad range of conditions. Eventually we hope to probe sample structure in Poiseuille flow at high shear rates, under high pressure head, and relatively high temperatures. This builds upon an existing suite of Couette rheoSANS and...

9. Contr. Talk 12 - Effect of confinement on lyotropic lamellae dynamics under shear flow

Dr Luigi Gentile (Department of Biology, Microbial Ecology Group, Lund University)

Lyotropic lamellar phases under shear flow show surprising changes in the microscopic structures and physical properties. Lamellae-to-multi-lamellar-vesicle (MLV) transition has been widely investigated, whereas lamellae tilting and vesicles inclination have not been highlighted during this kind of transition. Flow instabilities and their correlation with structures and properties in a...

10. Contr. Talk 13 - Studying slow dynamics with X-ray photon correlation spectroscopy

Oier Bikondoa (ESRF-The European Synchrotron, Grenoble, France)

Scattering experiments based on coherent X-ray beams have opened new possibilities for the investigation of soft and hard condensed matter. X-ray photon correlation spectroscopy (XPCS) allows to access a wide variety of dynamic phenomena at the nanoscale by studying the temporal correlations among photons that are scattered by a material when it is illuminated using a coherent X-ray beam.
