DEVICE AND METHOD FOR PRODUCING STATIONARY MULTI-COMPONENT LIQUID CAPILLARY STREAMS AND MICROMETRIC AND NANOMETRIC SIZED CAPSULES

摘要

The invention relates to a device and method for generating liquid capillary streams of multi-component immiscible liquids, the diameter of which may ran ge from tens of nanometers to hundreds of microns and to a relatively monodispersed aerosol of electrically charged multi-component droplets generated by rupture of the streams due to capillary instabilities. Said immiscible liquids flow at appropriate volumes through metal needles that ar e connected to a high voltage source in such a way that all the needles are contained inside one needle. The needles may or may not be placed concentrically relative to one another. The electric forces extrude the streams thereby resulting in diameters ranging from 100 microns to a few nanometers. The device and method disclosed in the invention can be used in fields such as materials science and food technology, wherever generation an d controlled handling of structured micrometric and nanometric sized streams i s an essential part of the process.
