Recent Advances in the Interfacial Shear and Dilational Rheology of Polymer Systems: From Fundamentals to Applications [PDF]
Polymers, 2022 The study of the viscoelastic properties of polymer systems containing huge internal two-dimensional interfacial areas, such as blends, foams and multilayer films, is of growing interest and plays a significant role in a variety of industrial fields. Hence, interfacial rheology can represent a powerful tool to directly investigate these complex polymer–

Shear and dilational interfacial rheology of surfactant-stabilized droplets
Journal of Colloid and Interface Science, 2012 A new measurement method is suggested that is capable of probing the shear and dilational interfacial rheological responses of small droplets, those of size comparable to real emulsion applications. Freely suspended aqueous droplets containing surfactant and non-surface-active tracer particles are transported through a rectangular microchannel by the ...

Behaviour of potato protein-pectin conjugates in emulsions: Insights from interfacial shear rheology
Food HydrocolloidsIt is currently known that conjugation can improve the emulsion-stabilising properties of plant proteins, although the properties of conjugate samples at the oil/water interface are still unclear. This study characterises the interfacial rheological properties of potato protein-pectin conjugates, focusing on the impact of pH and pectin type.

Operating windows for oscillatory interfacial shear rheology [PDF]
Journal of Rheology, 2019 Interfacial rheology becomes important when surface active species such as surfactants, particles, or proteins are present in sufficient quantities at liquid-liquid interfaces and interact between them. Interfacial rheometry measurements are challenging for various reasons.

Contactless interfacial rheology: Probing shear at liquid–liquid interfaces without an interfacial geometry via fluorescence microscopy [PDF]
Journal of Rheology, 2022 Interfacial rheology is important for understanding properties such as Pickering emulsion or foam stability. Currently, the response is measured using a probe directly attached to the interface. This can both disturb the interface and is coupled to flow in the bulk phase, limiting its sensitivity.

Quantitative Relationship between Monolayer Domain Structure and Interfacial Shear Rheology [PDF]
Biophysical Journal, 2016 With micro-disc rheometry, we have been able to map out the viscosity of dipalmitoylphosphatidylcholine monolayers, and determine how the viscosity changes with additions of cholesterol and/or palmitic acid, which are common additives to clinical lung surfactants.

Interfacial shear rheology of β-lactoglobulin—Bovine submaxillary mucin layers adsorbed at air/water interface [PDF]
International Journal of Biological Macromolecules, 2017 The interfacial rheological properties of solutions of β-lactoglobulin (BLG), as a model food compound, mixed with bovine submaxillary mucin (BSM), a major salivary protein, have been investigated. Time, frequency, stress sweep and flow measurements have been performed at different pHs (7.4, 5.0 and 3.0), to investigate the air/water interfacial ...
