SCATTERING BY COMPLEX FLUIDS UNDER SHEAR

Scattering techniques are advancing knowledge of structural changes an d phase behaviour in flowing systems; this information increases our u nderstanding of rheological behaviour. Studies of sheared fluids at su rfaces and experiments with synchrotron X-ray scattering on thin films are showing potential in the investigation of novel flow geometries. Experiments can now quantitatively test theoretical models and have, f or example, highlighted the importance of hydrodynamic interparticle f orces.
