Last year I went on a rheology tour!! I gave 12 talks in 10 days in 7 locations around Australia and New Zealand, talking primarily about suspension rheology and how particle characteristics such as particle size and shape affect rheology.
I spoke about the stability of suspensions and the factor to consider when assessing suspension stability but another major focus was the viscoelastic properties of materials.
Viscoelasticity: A material that possesses both liquid and solid-like properties which may change depending on how we handle and treat it.
One great example of a viscoelastic material is pitch, asphalt or bitumen …

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 …

It is time to pop on my curly false moustache and chef’s hat to become high, mighty and judgmental about what has been bothering me lately: the ‘not so’ culinary delights on the rheology road….

Sauces, custards, creams and gravies… viscosity and consistency…it bothers me! We’ve all …

Over the last few years, the nail polish industry has really opened up its beauty box of tricks, and on the market today, to name but a few, we see nail polishes with “magnetic, gel, matte, glitter, crackle, stamping, quick-dry, caviar, sponge, color changing, leather and sandy” effects. There are also nail polishes with kale, silk and nylon extracts! It really has turned into an art form. However, in order for us to appreciate the wonders of these magical nail polishes, there must be some exciting science behind it all?

Nutri Ninja Pro Vs the Nutribullet
Smoothie Wars! Which blends the best?
Here at Malvern Instruments, we seem to enjoy testing the rheological properties of drinks, particularly those of the alcoholic variety! Just before Christmas John Duffy and Steve Carrington looked into the differences between traditional ales and more recently they explored the properties of Guinness. Any excuse to go down the pub…!
Therefore, it was probably about time to explore the healthier option on the drinks menu, and an ideal hangover cure – smoothies. Additionally this was a perfect opportunity to demonstrate …
