This week is the Annual European Rheology Conference (AERC) held in beautiful Copenhagen. It has been a great conference so far with the opening reception at the City Hall – what an impressive building.
Malvern had a talk on Tuesday with our very own Nordic Rheology Specialist, Mats Larsson, talking about how “Creep testing can be used as an alternative to multi wave oscillation for determining the true gel point of network polymers“.
The session was appropriately chaired by Professor Henning Winter who along with Francois Chambon set out the criterion for determining the true gel point in such systems 30 years ago [1,2]. It was a great talk, with a full house and lots of interest about our new and exciting test method.
The accompanying paper will be published in The Annual Transactions of the Nordic Rheology Society while the principle behind the approach can be found in a recent Malvern paper published in the Journal of Applied Rheology .
We are of course exhibiting here as well and have our own booth with our Kinexus rotational rheometer and some of our accessories on show.
It is great to see so many familiar faces from last year’s international conference in Japan, and like in Japan there have been some very interesting talks on a variety of subject matters and materials including foods, suspensions, blood, proteins, foams, polymers and powders etc. It just shows how relevant rheology is for so many different materials, sectors and applications and it gets more diverse every year.
Tonight, we venture out for dinner to dine beside the ‘little mermaid’ – Copenhagen’s famous attraction from H.C. Anderson. After hearing all about the rheology and tribology of food today, let’s hope the cuisine on offer meets those mouth feel expectations!
Malvern will also be sponsoring next week’s meeting of the Institute of Non-Newtonian Fluid Mechanics in the Idyllic setting of Lake Vyrnwy in Wales.
Alex Malm of Malvern will be presenting a poster based on his PhD work at University of Manchester; Measuring elastic turbulence of DNA solutions using optical coherence tomography (OCT) velocimetry.
