Interfacial Rheology: Fundamental Overview and Applications

Overview

Interfacial rheology dominates the behavior of many complex fluid systems. Whether the system is characterized by a fluid-fluid interface or fluid-air interface, these characteristics influence the behavior of biological systems, oil recovery, personal care products, food and more. Learn the basic forces that drive interfacial dynamics and stability, what we can learn from them about product performance and therapeutic efficacy, and how we can measure them accurately. Specific illustrations will be presented using examples of biofilms, hydrates, asphaltene-stabilized emulsions, and engineered emulsions.

About the Speaker

Gerald Fuller is the Fletcher Jones II Professor of Chemical Engineering at Stanford University where he has carried out research and taught since graduating from Caltech in 1980. Professor Fuller’s research has centered on three areas of rheology: optical rheometry, extensional rheology, and interfacial rheology. This experimental effort has been aimed at a wide range of soft materials that includes polymer solutions and melts, liquid crystals, suspensions, and surfactants. Recent applications are especially focused on biophysics and a wide range of interfacial phenomenon. Professor Fuller received the Bingham Award from The Society of Rheology and is a member of the National Academy of Engineering and the American Academy of Arts and Sciences.

An Introduction To High Pressure Rheology

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.

The Role of Interfacial Elasticity on the Rheological Behavior of Polymer Blends: João Maia, Ph.D.

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 otherwise immiscible components. Compatibilizers also modify the rheology of the blend in complex and important ways. We must integrate extensional rheology, shear rheology, and other techniques to develop a complete understanding of this rich behavior. This webinar will use case studies of two compatibilized blends to elucidate the effect that compatibilizers have on the elasticity of polymer blends and the mechanism behind that behavior.

About Professor João Maia

His main research interests lie in the areas of rheology applied to polymer processing, with an emphasis on the development of new functional multiphase polymeric materials, e.g. blends and composites, on-line sensoring of extrusion and compounding, and extensional rheology.

He has published more than 300 scientific works, including 8 patents, more than 80 papers in international refereed journals, and more than 200 communications to International Conferences, of which more than 20 were Invited/Plenary/keynotes. He was a Fulbright Fellow in 2007 and received the 2010 Annual Award of the British Society of Rheology and the 2011 Morand Lambla Award of the Polymer Processing Society, the latter the highest honor of the PPS. He was the organizer and Co-Chairman of the XVIth International Congress on Rheology held in Lisbon, Portugal in August 2012.

He currently leads five scientific R&D projects and another twelve in cooperation with industry, for a total funding in excess of $5,000,000. His research group is currently constituted by three post-doctoral researchers, fifteen PhD students and several undergraduate students.

Neil Cunningham: Essential tools for the new Rheologist.

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 answer questions such as:

  • What is viscoelasticity and how does it relate to structured fluids and soft solids?
  • What is the difference between rate-control and stress-control, and what common processes are associated with each?
  • What are shear thinning and thixotropy? How do these apparently similar phenomena differ from one another?
  • What is the difference between strength and rigidity in structured fluid and soft solid structure?
  • What are normal stresses and why are they important?

Join us for an applied, accessible introduction to these important tools for understanding and describing rheological behaviour.

About the Speaker

Neil Cunningham is the founder and director of the Centre for Industrial Rheology (www.rheologylab.com). Neil started his career in rheology in 1995 as a sales engineer for TA Instruments in the United Kingdom and Rheometric Scientific throughout the UK and Europe. Since becoming an independent consultant in 1998, Neil has consulted for many hundreds of companies worldwide and has trained an estimated three thousand formulators, researchers, process designers, and quality controllers in the principles and practical application of rheology and viscosity testing. Over that time he has gained an intimate knowledge of rheometry and viscometry and has gained a unique breadth of understanding of the needs of industries from pharmaceuticals and consumer healthcare products, to foods, cosmetics, and industrial coatings and adhesives.

In 2012, Neil founded the Centre for Industrial Rheology, a specialist laboratory in Hampshire, England, providing sample testing services, practical training courses, and advice for companies looking to gain a better understanding of the behavior of their products.

Neil has gained a reputation for his accessible, enthusiastic approach to rheology and his ability to convey seemingly impenetrable concepts to even the most non-technical person.
