High pressure rheology explores phenomena that are not accessible at ambient laboratory conditions. Three of the advantages of using a pressure rheometer cell include a controlled environment for volatile fluids, saturating fluids with soluble constituents, and exploring new phase space using a combination of temperature and pressure.
Randy H. Ewoldt: Experimental Challenges of Shear Rheology, How to Avoid Bad Data How do you know when to trust your rheology data? How do you avoid bad data? Is there a checklist? Can you co-plot quantitative experimental boundaries against measured data? This presentation will discuss techniques for identifying and minimizing experimental errors and for…
Norman J. Wagner: An Introduction to Colloidal Suspension Rheology Colloidal suspensions are encountered across a broad range of natural phenomena and industrially relevant products and processes. From coatings and inks, to foods and pharmaceuticals, dispersions, sols, gels, and glasses of colloidal particles exhibit a rich rheological behavior. This webinar will present an introductory overview of…
João Maia, Ph.D. The Role of Interfacial Elasticity on the Rheological Behavior of Polymer Blends https://www.youtube.com/watch?v=PZyr-_uPGRg&feature=youtu.be The Role of Interfacial Elasticity on the Rheological Behavior of Polymer Blends Polymer blends are commonly used to generate materials with a desired combination of performance properties and cost. Most polymer blends are compatibilized to promote stability of the…
Neil Cunningham: Essential tools for the new Rheologist. https://www.youtube.com/watch?v=WPf-jtzIboA What is rheology and how can you use it to practically describe the flow and deformation of structured fluids and soft solids? Neil Cunningham will provide an accessible introduction to key rheological behaviours that will enhance your tool kit for understanding these important product characteristics. He will…
In this TA Webinar, Professor Nand Kishore discusses how to best discover and interpret protein folding, ligand binding, aggregation and molecular partitioning in self assemblies. Tribology complements rheology, providing information on solid-solid interactions that adds insight to the bulk fluid measurements of rheology. Tribology is especially concerned with quantifying the coefficient of friction as a…
Extensional flows dominate many polymer processes, including blow molding, film blowing, fiber spinning, thermoforming and many others. The rheology of polymeric materials under extensional flows can differ significantly from shear flows and it is important to understand this in order to optimize both materials and processes. In this webinar, we will: Introduce examples of extensional…
Tribology complements rheology, providing information on solid-solid interactions that adds insight to the bulk fluid measurements of rheology. Tribology is especially concerned with quantifying the coefficient of friction as a function of sliding speed and load force, under dry or lubricated conditions. This provides useful information about lubrication, wear, tactility, and mouthfeel.
The combination of optical microscopy with rheological tests enables direct observation of material structure under shear deformation. This provides critical information that can help understand, predict, and tune the material response under processing, storage, or end-use conditions.
