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 plane Poiseuille flow of the continuous oil ...

Exergy destruction in adiabatic pipeline flow of surfactant-stabilized oil-in-water emulsions is investigated in five different diameter pipes. The dispersed-phase (oil droplets) concentration of the emulsions is varied from 0% to 55.14% vol. The emulsions are Newtonian in that the viscosity is independent of the shear rate. For a given emulsion and pipe diameter, the exergy destruction rate pe...

The effect of type of emulsifier, 2 w/w% whey protein concentrate (WPC) or 2 w/w% WPC and 0.1 w/w% chitosan (CH) on the rheological changes and droplet size distribution during the ex vivo digestion of oil in water emulsions (pH 2) containing 1 w/w% rapeseed oil (RSO) were investigated. The procedure was used to mimic the human gastro duodenal digestion in two steps, gastric phase at pH 2 for 3...

Polymerization conditions in the Pickering emulsion of colloidal silica-stabilized polystyrene latex were optimized. The influence process on various parameters, including particle size and distribution was investigated. Monomodal particles obtained by conducting at a temperature 80°C slightly acidic environment (pH = 5), while maintaining fast monomer conversion. It has been shown that amount ...

Double emulsions are a promising formulation for encapsulation and targeted release in pharmaceutics, cosmetics food. An inner water phase is dispersed an oil phase, which again emulsified second phase. The encapsulated can be released via diffusion or coalescence, neither of desired during storage but might intended application. two interfaces double emulsion stabilized by hydrophilic lipophil...

Due to increased environmental and health concerns, there has been an demand for sustainable natural emulsifiers/stabilizers create a stable O/W emulsion. their unique properties, cellulose nanocrystals (CNC) have considerably investigated as stabilizer producing However, the utilization of CNC stabilized emulsion is only limited viscous or semi-solid foods. Hence this study investigates modifi...

Phospholipid-stabilized microbubbles are utilized as contrast agents in medical ultrasound imaging, and researchers currently investigating their potential theranostic agents. Due to the inadequate water solubility poor stability of numerous new therapeutics, development stable with capacity encapsulate hydrophobic therapeutics is necessary. Herein, we proposed a flow-focusing microfluidic devi...
