Abstract: The invention involves electrospray ionization of dissolved substances at atmospheric pressure in the ion source of a mass spectrometer. A chip with a multitude of spray nozzles is proposed, where each individual spray nozzle is surrounded by several sheath gas nozzles, preferably in a symmetric arrangement, for the jet-like introduction of a sheath gas. A shared attracting-voltage electrode is positioned substantially opposite the spray nozzles. The attracting-voltage electrode may have a tapering (e.g. funnel-shaped) opening above each spray nozzle so that the sheath gas jets are forced to closely envelop the spray jet, which is comprised of ions and very fine droplets. Heavier ions and droplets are thus prevented from discharging on the surfaces of the openings of the attracting-voltage electrode. Special measures can be taken to make all spray nozzles spray uniformly and to supply them with substance peaks from chromatographic or electrophoretic separators as simultaneously as possible.

Abstract: The present invention is directed to a multiplexed system for electrospraying cooling fluid to produce electrically charged droplets essentially uniform in size for cooling applications. The system comprise a preferably microfabricated fluid distributor consisting of multiple nozzles/atomizers from which the droplets are dispersed, an extractor electrode consisting in an electrically conductive plate with multiple holes coaxial with the nozzles and a third electrode consisting of either the surface to be cooled or another conductive material in contact with said surface. The system provides highly efficient cooling by avoiding the droplet rebound, when the charged droplets are pinned on the surface to be cooled by the electric image force. Testing of a prototype system demonstrated a heat flux removal of 96 W/cm2 with a remarkable cooling efficiency reaching 97%. Applications of the invention pertain to the effective removal of high heat flux from microelectronic chips or similar devices with cooling requirements.

Voltage is applied to the atomization electrode when the condensed water is produced to generate charged fine water droplets. A partition plate includes an insertion hole that receives the electrode body of the atomization electrode.

Abstract: A method of forming a material structure from structural units contained within a liquid solution in a spray head is described. The liquid solution includes a solvent and a solute, the solute comprising a plurality of the structural units, the structural units including monomer units, oligomer units, or combinations thereof. The method comprises forming droplets of the liquid solution including the structural units, and spraying the droplets on a substrate, thereby substantially increasing the reactivity of the structural units within the droplets relative to the structural units within the liquid solution in the spray head. The increase in reactivity can result from the droplets containing an excess of a particular ion, the ion excess resulting from a voltage applied to conductive walls of the device which dispenses the droplets. The material structure is then formed on the substrate from the more highly reactive structural units within the droplets.
