Sorbitan Tristearate Layers at the Air/Water Interface Studied by Shear and Dilatational Interfacial Rheology

Langmuir, 2005
The shear and dilatational rheology of condensed interfacial layers of the water-insoluble surfactant sorbitan tristearate at the air/water interface is investigated. A new interfacial shear rheometer allows measurements in both stress- and strain-controlled modes, providing comprehensive interfacial rheological information such as the interfacial ...

Towards the synthesis of hydroxyapatite/protein scaffolds with controlled porosities: Bulk and interfacial shear rheology of a hydroxyapatite suspension with protein additives

Journal of Colloid and Interface Science, 2013
The synthesis of porous hydroxyapatite scaffolds is essential for biomedical applications such as bone tissue engineering and replacement. One way to induce macroporosity, which is needed to support bone in-growth, is to use protein additives as foaming agents.

Interfacial Rheology of Globular and Flexible Proteins at the Hexadecane/Water Interface:  Comparison of Shear and Dilatation Deformation

The Journal of Physical Chemistry B, 2004
After long-time exposure, protein adsorption at fluid/fluid interfaces is documented to produce interfacial, gellike networks. Formation of this network apparently results from adsorption-induced conformational changes and subsequent interprotein aggregation at the interface. We utilize interfacial shear and dilatational rheology to probe the structure

Interfacial Shear Rheology of Aged and Heat-Treated β-Lactoglobulin Films:  Displacement by Nonionic Surfactant

Journal of Agricultural and Food Chemistry, 2000
Interfacial shear rheology of adsorbed beta-lactoglobulin films (bulk protein concentration 10(-)(3) wt %) has been studied over the temperature range 20-90 degrees C using a two-dimensional Couette-type viscometer. Effects of the type of interface (air-water, triolein-water, and n-dodecane-water), the pH (2.0, 5.6, 6.0, 7.0, and 9.0), and the extent ...

Interfacial shear rheology study of wet foams

, 2007
The texture and the persistence of the wet foam of tiny sphere-shaped gas bubbles that tops the espresso coffee liquid phase are of the utmost importance for the quality of this brew. The prevailing liquid phase of the wet foam solubilizes biopolymers and natural surfactants which will participate to the formation of the liquid films framing the gas ...

Combined surface pressure-interfacial shear rheology studies of the interaction of proteins with spread phospholipid monolayers at the air–water interface

International Journal of Pharmaceutics, 2005
The adsorption of two model proteins, catalase and lysozyme, to phospholipid monolayers spread at the air-water interface has been studied using a combined surface pressure-interfacial shear rheology technique. Monolayers of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC), 1,2-dipalmitoyl-sn-glycero-3-[phospho-rac-(1-glycerol)] (DPPG) and DPPC:DPPG (

Viscoelastic characterization of the crosslinking of β-lactoglobulin on emulsion drops via microcapsule compression and interfacial dilational and shear rheology

Journal of Colloid and Interface Science, 2020
Interfacial rheology provides insight into the mechanical properties of adsorption layers on liquid-liquid interfaces, which mediates the stability of emulsion droplets. The use of capsule compression at the scale of an emulsion droplet to probe the interfacial rheology may open up the possibility of testing the interfacial rheological properties of ...

Interfacial shear rheology of glassy polymers at liquid interfaces

Journal of Rheology, 2023
When surface-active molecules or particles assemble at fluid–fluid interfaces, these interfaces acquire complex rheological properties that are of importance in processes that involve flow and deformation of interfaces. Although much progress has been made, interfacial rheology measurements and, in particular, the measurement of interfacial rheological
