Abstract

A continuous and scalable bubbling system for functional nanoemulsions was reported. For each experiment, a thin layer of the dispersed phase nonpolar oil, was deposited on an aqueous solution containing an ionic surfactant. Air bubbles were formed at the tip of a tube located at the bottom of the tank. The bubbles rose to the interface because of buoyancy. The size of the bubbles were changed by adjusting the injection pressure and the diameter of the tube. The bubbling frequency was adjusted to 0.1?1 Hz and it was made sure that there were at most a few bubbles at the interface without forming a bubble column Each experiment ran for 48 h to produce enough sub-micrometer droplets to be detected. To reduce the influence of dust, the container was cleaned before each experiment. The UV-cured experiments were carried out using a UV oven to crosslink the particles. The DLS result for the water sample after heating shows a smaller mean droplet diameter which suggests one way to eliminate the oil phase in the lipid nanoemulsions.
