The droplet-based microfluidic technology has a potent high throughput platform for biomedical research and applications [1]. Recently, Link et al. showed that an electric field can be very useful to control water droplet in carrier oil [2]. In this research, simultaneous droplet formation and sorting has been demonstrated using an electric field, allowing very precise droplet sorting to different outlets depending on the electrical actuation.

Transparent model oils are commonly used to study the flow patterns and pressure gradient of crude oil-water flow in gathering pipes. However, there are many differences between the model oil and crude oils. The existing literatures focus on the flow pattern transition and pressure gradient calculation of model oils. This paper compares two most commonly used model oils (white mineral oil and silicon oil) with Xinjiang crude oil from the perspectives of rheological properties, oil-water interfacial tensions, emulsion photomicrographs and demulsification process. It indicates that both the white mineral oil and the crude oils are pseudo plastic fluids, while silicon oil is Newtonian fluid. The viscosity-temperature relationship of white mineral oil is similar to that of the diluted crude oil, while the silicon oil presents a less viscosity gradient with the increasing temperature. The oil-water interfacial tension can be used to evaluate the oil dispersing ability in the water phase, but not to evaluate the emulsion stability. According to the Turbiscan lab and the stability test, the model oil emulsion is less stable than that of crude oil, and easier to present water separation.

Apparent Influence

Studies on the chemical control of sucker growth on cigar tobacco showed that a mineral oil-water emulsion applied to the stub of the broken stem after the plant was decapitated and diethanolamine salt of maleic hydrazide sprayed on the leaves suppressed sucker growth significantly and increased the yield of the cured crop. Each chemical treatment resulted in a decrease in the percentage content of total alkaloids, nicotine, calcium, and total ash in the cured leaf but had no apparent influence on the content of total nitrogen, nornicotine, potassium, phosphorus, magnesium and chlorine.
