Device and procedure to generate steady compound jets of immiscible liquids and micro/nanometric sized capsules

1. - Device to produce steady compound multi-component liquid jets and micro and nanometric sized capsules, consisting of a number N of feeding tips of N liquids, such that the i-th liquid is injected at a flow rate Qi through the i-th tip, where i varies between 1 and N. The feeding tips are arranged such that the (i−
- 1)-th liquid surrounds the i-th tip, and each tip is connected to an electrical potential Vi with respect to a reference electrode. The i-th liquid, which flows trough the i-th tip, is immiscible or poorly miscible with liquids (i+1)-th and (i−
1)-th. An electrified capillary liquid meniscus with a noticeable conical shape forms at the feeding points exit in such a way that from the cone apex issues a steady capillary jet made up of the N liquids, such that the (i-1)-th liquid surrounds the i-th liquid, and such that the diameter of the capillary jet has a value between 100 microns and 15 nanometers which is much smaller than the characteristic diameter of the liquid meniscus from which the jet is emitted.

Abstract
A device and method for generating drops. The drops are generated by applying an electrical potential to a set of feeding tips which have immiscible or poorly miscible liquids running through them.

- 2. - Device to produce steady compound multicomponent liquid jets and micro and nanometric sized capsules, consisting of a number N of feeding tips of N liquids, such that the i-th liquid is injected at a flow rate Qi through the i-th tip, where i varies between 1 and N. The feeding tips are arranged such that liquid 1 surrounds all the other feeding points. Liquid 1 is immiscible or poorly miscible with the rest of liquids. Each feeding point is connected to an electrical potential Vi, where i varies from 1 to N, respect to a reference electrode. An electrified capillary liquid meniscus with a noticeable conical shape forms at the feeding points exit in such a way that from the cone apex issues a steady capillary jet made up of the N liquids, so that liquid 1 surrounds the rest of liquids, and such that the diameter of this capillary jet has a value between 100 microns and 15 nanometers which is much smaller than the characteristic diameter of the electrified liquid meniscus from which the jet is emitted.
