Trapping of Gas Bubbles Injected through Capillary Electrodes into Dielectric Liquid
TLDR
In this article, the electric force plays an important role in the trapping of air bubbles under the capillary electrode dipped in a dielectric liquid, and the maximum trapping time is about 20 min.Abstract:
Trapping of air bubbles under the capillary electrode dipped in a dielectric liquid is found experimentally. The trapping is observed only in some kind of liquid in which a remarkable rise of the free surface along the electrode has been observed. Only bubbles injected from the charged capillary electrode can be trapped. The maximum trapping time is about 20 min. The electric force is shown to play an important role in the trapping. Trapped air bubbles slightly oscillate vertically and horizontally accompanied by a pulsation at a frequency of several kHz.read more

Electric and Magnetic Separation via Contactless Suspension of Particles, Droplets, and Bubbles
TL;DR: The theoretical relationship existing between these techniques and the methods employed for free levitation of solid objects in vacuum and in mid-air are examined in this article, as well as systems associated with magnetic and electric separation methods.
