Effect of temperature on whey protein isolated (WPI) films adsorbed at the water-oil interface

Grasas y Aceites, 2002
Heat-induced interfacial aggregation of a whey protein isolate (WPI) with a high content of β-lactoglobulin, previously adsorbed at the oil-water interface, was studied by interfacial dynamic characteristics (interfacial tension and surface dilational ...

Synthesis and Nucleation Mechanism Recognition of BaSO4 Nanoparticle in the Presence of Biopolymers [PDF]

Journal of Nanostructures, 2019
A major portion of BaSO4 is used as drilling fluid additives in the presence of some biopolymers such as starch and PAC (Polyanionic Cellulose) as filtration control and viscosifier.

Smoothed Dissipative Particle Dynamics model for mesoscopic multiphase flows in the presence of thermal fluctuations

, 2015
Thermal fluctuations cause perturbations of fluid-fluid interfaces and highly nonlinear hydrodynamics in multiphase flows. In this work, we develop a novel multiphase smoothed dissipative particle dynamics model.

Characterization and identification of the most appropriate nonionic surfactant for enhanced oil recovery

Journal of Petroleum Exploration and Production Technology, 2019
The paper focuses on the behaviour of nonionic surfactants (NISs) for enhanced oil recovery (EOR) processes with special reference to its applicability in the reservoirs of Upper Assam. The present work specifically studies three NISs, viz. Tergitol 15-s-

Phase-field modeling droplet dynamics with soluble surfactants [PDF]

, 2010
Using lattice Boltzmann approach, a phase-field model is proposed for simulating droplet motion with soluble surfactants. The model can recover the Langmuir and Frumkin adsorption isotherms in equilibrium.

Tensiometry as a Simple Analytical Method for Quantification of Solubility and Release of Aroma Molecules in Aqueous Media

Molecules, 2021
Dynamic tensiometry is shown to be a high-potential analytical tool in assessing physico-chemical characteristics of fragrance molecules, such as solubility limit, volatility as well as much rarely assessed interfacial activity of these amphiphilic ...

Emulsions stabilised by whey protein microgel particles: Towards food-grade Pickering emulsions [PDF]

, 2014
We have investigated a new class of food-grade particles, whey protein microgels, as stabilisers of triglyceride-water emulsions. The sub-micron particles stabilized oil-in-water emulsions at all pH with and without salt.
