Once more, Professor Mackley and his wife kindly invited the members of the Polymer Fluids Group and their partners to party at his home on the 3rd December to celebrate the start of winter. All who attended enjoyed the evening and would like to thank Margaret and for the excellent food and drink. A special thank you goes to Amanda for the pumpkin cheesecake.

The Polymer Fluids Group took part in the Nuffield Science Bursary Scheme again this year. The scheme allows sixth form students to gain experience of research in an academic or industrial laboratory for approximatley one month during the summer vacation. The regonal co-ordinator for the Cambridge area is STEM Team Cambridgeshire. This year Eleanor Mottram worked with Drs Simon Butler, Damien Vadillo and Tim Lord to investigate the rheology of hens eggs. This included studying the rheology of egg white, yolk and scrambled egg and investigated the effect of heating.

Members of the Polymer Fluids Group attended the Polymer Processing Society's 24th annual meeting, which was held a Salerno, Italy. The group gave the following presentations:

  • The development of voidage and capillary size within extruded plastic films - Dora Medina
  • The processing of optically transparent polystyrene blends filled with cross-linked polystyrene beads - Tim Lord
  • Flow-induced crystallisation of polyethylene and polypropylene melts - Lino Scelsi
  • The Rheology and Microstructure of Carbon Nanotube (CNT) Suspensions - Anson Ma

Bioenergy: Challenges and Opportunities: Portugal, 6th - 9th April 2008

Ben Taylor, Arjan Abeynaike, and Nuno Reis attended the international conference and exhibition on bioenergy from 6th - 9th April at the University of Minho in Guimaraes, Portugal. The conference, entitled "Bioenergy: Challenges and Opportunities", included experts in fields ranging from ecology and engineering to economics and politics. There were many views presented on the directions in which bioenergy will or should focus, but a consensus that bioenergy must play an important role in worldwide energy and fuel was clearly evident. The hot topics of the conference were anaerobic digestion to produce biogas, traditional, 1st generation biofuels generated from crops such as rapeseed and maize, 2nd generation biofuels from cellulosic crop materials, and the special category of biofuels generated from algae. The conference proved a worthwhile endeavour, bringing together top researchers to address crucial environmental, social, and fuel supply security concerns and potential solutions. The setting was wonderful, the people delightful, and the content stimulating.


David goes to the East

Dr David Hassell, who has worked in the Polymer Fluids Group for a number of years, has left to take up a lecturing position at the University of Nottingham's Malysia Campus. David will be working in the School of Chemical and Enviromental Engineering. This follows his successful research on polymer melts conducted as part of the second microscale polymer processing consortuim (muPP2). We wish David all the best in the future.


muPP2 Spring Meeting: University of Bradford, 2nd - 4th April 2008

Professor Mackley, David Hassell, Tim Lord, Lino Scelsi and Simon Butler attended the muPP2 Spring meeting in Bradford during the Easter break. The meeting was held to discuss the latest research conducted as part of the second Microscale Polymer Processing consortium. Lino gave a presentation on his work investigating polymer crystallisation entitled "Flow-induced crystallisation of HDPE and PP in a Multi-Pass Rheometer". He and Tim Lord also presented posters to the meeting entitled:

  • The sensitivity of the numerical predictions of principal stress difference (PSD) and pressure difference for a HDPE flowing in an abrupt contraction to the choice of fitting parameters for a tube-theory based constititutive equation. Lino Scelsi
  • The processing behaviour of an optically transparent polystyrene blend in which the polystyrene matrix is filled with cross-linked polystyrene beads, Tim Lord
