Abstract: A method for delivering an aerosol, especially an aromatic aerosol, comprising the steps of contacting a capillary wick, comprising an EHD comminution site, with a liquid source, whereby at least a portion of the liquid transports to the EHD comminution site; applying a voltage to the liquid within the capillary wick at a location spaced apart from the liquid source and proximate the EHD comminution site; and applying a ground reference at a location external to the EHD comminution site, wherein at least a portion of the liquid EHD comminutes to form a spray having a generally-consistent flowrate and a device therefor.

Abstract: Methods, and the products thereof, for producing nanoparticles that in some embodiments are at least partially encapsulated by an encapsulant; and methods, and products thereof, for producing nanoformulations that are suspensions of nanoparticles in a liquid formulation. Typically the nanoparticles include agrochemicals, pharmaceuticals, catalysts, and other active ingredients.

Abstract: A non-respirable aerosol, particularly a non-respirable aerosol comprising a biologically-effective amount of a biologically-active agent dissolved, emulsified, or suspended in a highly-aqueous liquid carrier vehicle. The highly-aqueous liquid carrier vehicle comprises about 60 wt % to about 100 wt % water, about 0 wt % to about 40 wt % of a co-solvent, about 0.05 wt % to about 10 wt % of an acceptable surfactant, and about 0 wt % to about 10 wt % of an excipient. The non-respirable aerosol is substantially monodisperse when dispensed from a sprayhead assembly comprising a preferably linear array of a plurality of nozzles and at least one counter electrode adapted to substantially equalize the charge fields of the plurality of nozzles.

Abstract: A spray head for use with an electrohydrodynamic spray device is provided. The spray head comprises at least one nozzle and a shroud that at least partially surrounds the nozzle. The nozzle is configured to provide a charged aerosol from a liquid formulation. The nozzle comprises a manifold having at least one fluid entrance and one or more discrete fluid spray sites.

Abstract: A method and device are provided for providing sensory cues, signals, or indicators regarding the status of electrohydrodynamically spraying a material, including power-on status of an electrohydrodynamic spray device, active electrohydrodynamic spray status, and material status within the electrohydrodynamic spray device. In particular, audible, tactile, or intermittent visible signals indicate active electrohydrodynamic spraying, audible, tactile, or visible signals indicate power-on status of the electrohydrodynamic spray device, and sensory signals indicate the status of other operationally-related variables, including the rate of electrohydrodynamic spray, time increments, which may be correlated with electrohydrodynamic spray flowrates, and material supply levels.
