Kinexus

The Kinexus rheometer design has been underpinned with the market-defining strengths of the previous generation Bohlin rheometers, coupled with advances in shear and vertical (axial) testing, to deliver a rotational rheometer platform with unprecedented dual-action capabilities.

Commentary, courtesy of Everett Crews (Ingevity), and AMAP
Although the history of the scientific study of the flow of matter is replete with names of our greatest thinkers, from Aristotle, Galileo, and Newton to Maxwell, Edison, and Einstein, the term “rheology,” like the science itself, was arguably born in the early twentieth century. The English-speaking world attributes the creation of the term, “rheology,” to E.C. Bingham and J. R. Crawford in 1929, although the word had been in use in German scientific literature as early as 1901 (the French limnologist, Francois …

The most common approach for measuring time-dependent viscoelastic properties of a material on a rotational rheometer is to perform small amplitude oscillatory shear (SAOS) over a range of oscillation frequencies – commonly referred to as a frequency sweep – where the sample is oscillated back and forth with a given stress or strain. Here the oscillation frequency, measured in rad/s, is equivalent to 1/t, with t the deformation time of the material.
Let’s consider a sample of Play Putty which is a viscoelastic material. At short deformation times (high frequencies) Play …

So, which is it? I get asked this simple question more and more with the increased interest in Superpave. Superpave (SUperior PERforming Asphalt PAVEments) was developed by the Strategic Highway Research Program (SHRP) in the United States to help improve performance, efficiency, durability and safety of the highway system. As many more countries adopt Superpave or at least parts of it, there are many more individuals interested in understanding this new design system and all the new testing methods associated with it. Depending on what you search for, read in journals, …

Here at Malvern Panalytical, we seem to enjoy testing the rheological properties of drinks, particularly those of the alcoholic variety! John Duffy and Steve Carrington looked into the differences between traditional ales and 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 our latest dispersion geometry using John’s loyal drinking partner – the Kinexus rheometer!
We decided to run …

Le congrès du GFR est la réunion annuelle des rhéologues français. L’édition 2017 était très réussie avec un programme social intéressant dans la très belle ville de Nice.
Le congrès a enchaîné des sessions posters, quatre conférences plénières et des présentations orales avec entre autre celle de Frédéric Fraïsse qui a présenté la « Caractérisation de suspensions de nanoparticules de SiO2 » (voir photo ci-contre). Le congrès prévoyait également des espaces des discussions informelles et conviviales autour des stands d’exposition d’instruments auxquels nous avons participé.

Lors du 52ème Congrès du Groupe Français de Rhéologie (GFR), Guillaume Ovarlez (Directeur de recherche au CNRS, Laboratoire du Futur CNRS-Solvay, Pessac, France) a reçu le prix Maurice Couette et présenté ses travaux sur les inhomogénéités dans les écoulements de suspensions concentrées pour lesquels des rhéomètres de la gamme Kinexus ont été utilisés.
https://partage.legfr.social/index.php/s/ug25vSvEfExKacE
Monsieur Ovarlez a notamment expliqué que la rhéométrie classique fonctionnait très bien dès lors que les matériaux étudiés sont homogènes et que l’écoulement et lui aussi homogène. Cependant la structure des suspensions et leur écoulement peuvent s’influencer.
Ainsi, les …

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 …

To support the growing interest in Malvern PANalytical technologies for use in the food and drink industry, we held a joint free seminar devoted to this extremely important industry sector. This took place on Wednesday, June 8th in the Marriott Hotel Schaumburg, Chicago and saw more than 20 enthusiastic attendees from the food industry attend for an applications-focused set of presentations stressing the importance of Malvern PANalytical’s  complementary analytical techniques and the value they add to this sector.  We kicked off with a ‘Deluxe Continental Breakfast’ as befitting the attendees.

Personally, I must say that this was …

How to best measure a viscosity flow curve?
 
Choosing the right measuring geometry and preventing measurement artifacts
There are several ways to obtain viscosities at different shear rates using a rotational rheometer. For instance, we could gently ramp through the different speeds starting at the lowest and ending at the highest (good for a quick measurement where time is of the essence).  Alternatively, we could step through the required shear rates as discussed later, while waiting for a steady state viscosity at each step.  This is known as generating an equilibrium flow …

Controlling the performance of an ink is a complex optimization challenge. Understanding how features of the system, the dispersed particle size in particular, impact stability and behavior during each stage of the printing process is crucial for effective formulation.
Over the past 30 years, the use of commercial and industrial inks has changed substantially. In particular, the maturation of inkjet technology has revolutionized printing. From office printers through to industrial coding and marking systems, inks are now required to meet demanding performance targets, for a wide range of different applications.

The recently announced merger of Malvern Instruments and PANalytical could not be better timed from the Cement industry’s perspective. Both companies are market leaders in their respective technology fields – Malvern in particle characterization and PANalytical in elemental and mineralogical analysis – and both having strong teams of application experts with a lot of experience in cement production and characterization.
The synergy between the teams and product offerings was described in a recent webinar by Harald van Weeren of PANalytical and myself. The live event was attended by over one hundred participants and …

Why measure a viscosity flow curve, rather than just give a number?
 

Very often chemists are asked to provide a single viscosity value for a product or formulation without much information about the required conditions of the measurement.  For an oil or low viscosity liquid which is Newtonian this is pretty straightforward, so long as your viscometer is properly calibrated and the measurement temperature is provided. However, most industrially interesting or complex fluids such as polymer solutions, suspensions and emulsions are non-Newtonian, meaning that their viscosity varies with shear rate – …
