Title (EN) DEVICE AND METHOD FOR PRODUCING STATIONARY MULTI-COMPONENT LIQUID CAPILLARY STREAMS AND MICROMETRIC AND NANOMETRIC SIZED CAPSULES
(ES) DISPOSITO Y PROCEDIMIENTO PARA PRODUCIR CHORROS LÍQUIDOS COMPUESTOS MULTICOMPONENTES ESTACIONARIOS Y CÁPSULAS DE TAMAÑOS MICRO Y NANOMÉTRICO
(FR) DISPOSITIF ET PROCEDE PERMETTANT D'OBTENIR DES JETS LIQUIDES COMPOSES MULTICOMPOSANTS STATIONNAIRES ET DE CAPSULES AUX DIMENSIONS MICRO ET NANOMETRIQUES
Abstract:
(EN) The invention relates to a device and method for generating liquid capillary streams of multi-component immiscible liquids, the diameter of which may range 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 are 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 and controlled handling of structured micrometric and nanometric sized streams is an essential part of the process.
(ES) Esta invención describe un dispositivo y procedimiento para generar chorros líquidos capilares compuestos multi-componentes de líquidos inmiscibles cuyos diámetros pueden variar desde unas decenas de nanómetros hasta cientos de micras, así como un aerosol relativamente monodisperso de gotas multicomponentes, cargadas eléctricamente, generadas mediante la rotura por inestabilidades capilares de los chorros compuestos. Dichos líquidos inmiscibles fluyen, a caudales apropiados, a través de agujas metálicas conectadas a fuentes de alto voltaje, de tal modo que una de las agujas contiene en su interior a las demás, pudiento o no situarse concéntricamente entre sí. Las fuerzas eléctricas extrusionan los chorros hasta conseguir diámetros en un rango desde 100 micras hasta pocos nanómetros. El dispositivo y procedimiento objetos de la presente invención son aplicables a campos como Ciencia de los Materials y Technología de Alimentos, donde la generación y manipulación controlada de chorros estructurados de tamaño micro o nanométrico sea parte esencial del proceso.
(FR) L'invention porte sur un dispositif et sur un procédé permettant de générer des jets liquides capillaires composés multicomposants de liquides non miscibles dont les diamètres peuvent être compris entre des dizaines de nanomètres et des centaines de micra. L'invention porte également sur un aérosol relativement monodispersé aux gouttes multicomposants chargées électriquement et engendrées à travers la rupture par instabilité capillaire des jets composés. Lesdits liquides non miscibles s'écoulent, à des débits appropriés, à travers des aiguilles métalliques reliées à des sources haute tension, de manière qu'une des aiguilles contienne à l'intérieur les autres aiguilles susceptibles d'être disposées de manière concentrique. Les forces électriques profilent les jets jusqu'à obtention de diamètres allant de 100 micras jusqu'à quelques nanomètres. Le dispositif et le procédé sont applicables à des domaines, dont la science des matières et la technologie des aliments, dans lesquels la génération et la manipulation contrôlée de jets structurés de taille micro ou nanométrique constituent une partie essentielle du processus.
