    Abstract: Electrospray devices are described. The devices may comprise a substrate and a plurality of emitters. The emitters may comprise a plurality of channels therein, wherein the channels may be configured to convey immiscible liquids to the distal end of the emitters. The channels may be arranged such that, at the distal end, one liquid enclosed another liquid. The device may comprise a plurality of reservoirs, each reservoir being configured to contain liquid therein and to convey the liquid to a respective channel. Core-shell droplets may be formed by forming Taylor cones through the application of an electric field. The core-shell droplets may include a core liquid enclosed within a shell liquid, wherein the two liquids may be immiscible.

    Abstract: Microplasma generators and associated arrays and methods are described herein. Certain embodiments relate to a microplasma generator in which an elongated semiconductor structure can control electronic cun'ent supplied to a microplasma cavity. Plasmas can be created by supplying energy to a neutral gas so that free electrons and ions are created. In a thermal plasma, electrons, ions, and neutral atoms and/or molecules (referred to as “neutrals”) are in thermal equilibrium

    Abstract: Techniques for manufacturing miniaturized diaphragm pumps using additive manufacturing techniques, such as polyjet printing, are provided, as are the pumps and systems that result from using such techniques to produce the pumps. The provided pumps include a compression chamber that has a first surface, a second opposed surface, and a conical outer wall that extends between the first surface and the second surface and that has a bowed configuration in which the outer wall has a generally concave shape. A diaphragm is disposed proximate to the compression chamber, and the pump also includes one or more valves that control the flow of fluid between the compression chamber and one more fluid ports. Fluid can be selectively vacuumed into and exhausted out of the compression chambers. Various manufacturing techniques for fabricating the pumps are also provided.
