The British Society of Rheology held its Midwinter Meeting at the Department of Chemical Engineering, University of Cambridge, on the 8th and 9th December 2005. The Polymer Fluids Group hosted the meeting and the theme was Multiscale Rheology. Speakers included Professor Ken Walters, Professor Sir Sam Edwards, Professor Malcolm Mackley and Professor Tom McLeish.

Dr David Hassell is a Postdoctoral Fellow with the Polymer Fluids Group, working on Microscale polymer processing and the images show some of his results:

Profiles of principle stress difference for a long branched polyethylene (HDB2) taken in a Cambridge Multi-Pass Rheometer (MPR) with cross slot inserts. The images were captured using optical birefringence for a maximum extension rate of 14 s-1 at 155oC (left) and 175oC (right).
