Interfacial rheology: From fundamentals to application



Watch this recorded webinar to learn about:

Fluid interfaces present us with fascinating mechanical responses that control many physical phenomena encountered in liquid processing, human health, and the environment. A proper understanding of these forces requires the measurement of interfacial microstructure and how that microstructure responds to flow and deformation.

This webinar introduces the audience to methods of measurement and links them directly to applications. It begins with a brief overview to liquid interfacial science and the basic concepts of surface tension and interfacial rheology. Recognizing that the applications are fundamentally fluid mechanical in nature, the Webinar then discusses the boundary conditions where these interfacial forces are exerted. These conditions immediately recognize that two types of interfacial deformations must be considered: constant area shear and dilatation.

Commercial equipment that is available for these measurements are presented and three applications are highlighted for their use: coalescence of water droplets in the presence of asphaltenes, the stability of monoclonal antibodies, and the stability of liquid layers by lung surfactants.
