1 mar 2022 · The current work is a critical review to highlight the energy input needed to promote the formation of an emulsion and the type of emulsifying agents necessary to enable the appearance of oil-in-water or water-in-oil emulsion.
3 sty 2017 · The formation process consists of two steps: (1) the formation of water-in-oil droplets at a co-flowing structure formed by a syringe needle and a flexible microtubing, and (2) the formation of water-in-oil-in-water compound droplets at the tip of the microtubing by buoyancy.
27 gru 2021 · In this study, we demonstrate flow cytometry as a rapid, simple and efficient technique to characterize complex and polydisperse oil in water emulsions. In a matter of seconds, flow cytometry can provide a measurement of the size and complexity of these complex and dynamic systems.
11 kwi 2022 · The increasing output of oil–water emulsions poses a major challenge to industrial practice and environmental protection. The contribution of fine solid particles and surfactant-active agents to the formation of oil–water emulsions and the difficulties of separation are analyzed.
7 wrz 2020 · Two methods based on passive flow focusing and active pico-injection are demonstrated to generate water-water-oil double emulsions, achieving a high generation frequency of ~2.4 kHz.
1 sie 2021 · Water-in-oil emulsion formation is a result of crude oil and brine interfacial activities. • Brine-crude oil system with lowest IFT forms more stable and smaller emulsions. • Water snap-off and water shortcut are main mechanisms of in-situ water-in-oil emulsification. • Emulsion division and rupture are additional mechanisms of water ...
