Interfacial Rheology: From Emulsion Stability to Lung Surfactants

July 22, 2020 in Online | News Type: Technology:

Join Nanoscience Instruments for a webinar on Dilatational and Shear Interfacial Rheology measurements utilizing various techniques we provide in our instrumentation offerings.

Surface and interfacial tension measurements are often not enough to characterize complex interfaces. For example, in emulsions and foams for food, oil & gas, and personal care products, processes that are critical to stability including coalescence and Ostwald ripening have been shown to depend on interfacial viscoelasticity. In biological systems involving lung surfactants or eye lipids, the response of surface tension to dilatational and shear deformation through breathing or blinking is crucial for healthy physiological function, and interfacial rheology can characterize these responses. In each case, standard surface and interfacial tension measurements are not sufficient to properly characterize the film.

In this webinar we will discuss both dilatational and shear interfacial rheology measurement solutions including the Attension Theta Flex PD200, KSV NIMA Langmuir Trough, and KSV NIMA Interfacial Shear Rheometer, and we will close by highlighting several case studies that span these application areas.
