ULTRASONIC PRODUCTION OF NANO-SIZE DISPERSIONS AND EMULSIONS
Ultrasonic Production of Nano-Size Dispersions and Emulsions parameters of the ultrasound differ a lot. For each specific application and process there is a specific optimal parameter configuration. For new processes and formulations this configuration has to be identified. In the following the parameters important to the liquid

Microfluidization initiated cross-linking of gliadin
In summary, we demonstrated a facile and novel way to prepare structured emulsions with high algal oil volume fraction (φ oil = 50%) stabilized by gliadin particles via microfluidization initiated cross-linking. The cross-linking was firstly initiated by hydrophobic interaction after mild alkaline pH-shifting processes, and then ...

Efficient Emulsification of Viscous Oils at High Drop
It is shown experimentally in this study that the increase of drop volume fraction can be used as an efficient tool for emulsification of viscous oils in turbulent flow. In a systematic series of experiments, the effects of drop volume fraction and viscosity of the dispersed phase on the mean, d32, and maximum, dV95, diameters of the drops, formed during emulsification, are quantified.
Fabrication of Silica Nanospheres Coated Membranes
Contact angles were measured on a contact angle measurement machine (OCA15 machine, Data-Physics, Germany) at ambient temperature. The oil concentration in filtrate was measured using an infrared spectrometer oil content analyzer (Oil480, Beijing Chinainvent Instrument Tech. Co. Ltd., China). CCl4 was used to extract oil from filtrate.
Energies | Free Full-Text | Influence of Droplet Size
The influence of droplet size on exergy destruction rate in flow of highly concentrated oil-in-water emulsions was investigated experimentally in a cone and plate geometry. The oil concentration was fixed at 74.5% by volume. At this dispersed-phase (oil) concentration, two different droplet size emulsions were prepared: fine and coarse emulsions.
Entropy Generation in Flow of Highly Concentrated Non
Entropy generation in adiabatic flow of highly concentrated non-Newtonian emulsions in smooth tubes of five different diameters (7.15–26.54 mm) was investigated experimentally. The emulsions were of oil-in-water type with dispersed-phase concentration (Φ) ranging from 59.61–72.21% vol. The emulsions exhibited shear-thinning behavior in that the viscosity decreased with the increase in ...

Interfacial behavior of oil/oil and oil/water soluble
Instability of highly concentrated water-in-oil emulsions which contain a metastable inorganic salt solution in a form of drops arises from the crystallization of saltThe results showed that the interfacial study are important for the understanding of instability due to crystallization in emulsions with an
Effect of different surfactant mixtures on the stabilisation mechanism
The subject of this investigation was a highly concentrated water-in-oil emulsion (HCE), explosive grade, with volume fraction of approximately 88 volThe choice of co-surfactants depends on the nature of the components of the emulsion and is mainly empirically-based. The key concept is using
