Abstract: In an embodiment, the present disclosure pertains to a cavitation generation device that includes a dactyl plunger rotatable about an axis between an open position and a closed position and a propus socket having a channel. The propus socket is rigidly mounted below the dactyl plunger, and the dactyl plunger is received into the propus socket when the dactyl plunger is in the closed position. The cavitation generation device can also include a torsion spring that biases the dactyl plunger into contact with the propus socket. In another embodiment, the present disclosure pertains to a method of inducing a cavitation including biasing a dactyl plunger via a torsion spring, and rotating the dactyl plunger, by action of the torsion spring, into a propus socket. The propus socket includes a nozzle-shaped channel. The method further includes ejecting a socket cavity volume through the nozzle-shaped channel thereby inducing a cavitation event.

Abstract: A method and apparatus for depositing a film on a biological substrate are provided. A plasma generation device includes a dielectric conduit and a high voltage electrode. The plasma generation device is placed in proximity to the biological substrate and a gas supply that includes a precursor material is directed through the dielectric conduit. An electric field generated by the potential difference between the high voltage electrode and the biological substrate ionizes at least a portion of the gas supply and causes plasma to emanate from the dielectric conduit and contact the biological substrate. The plasma induces a reaction of the precursor material to form a film that is deposited on the biological substrate.

Abstract: Disclosed are example efficient circuits that produce spark discharges for hydrocarbon conversion (or treatment of other mixtures) using a high-voltage rectified DC supply to discharge a capacitor (either internal or external) across a two-electrode gap, optimized to minimize waste energy by operating in a constant current, approximately-constant current, or constant power mode. The circuits may operate off of a standard electrical supply line (e.g. 120 VAC or 240 VAC, 60 Hz, single-phase or multi-phase). The disclosed approach is scalable to any number of discharge gaps while maintaining similar pulse characteristics and electrical efficiency.

Abstract: A high voltage discharge generating a plasma wave front is disposed within a headspace over an oil-containing liquid in order to create various chemical changes within the headspace, and ultimately within the liquid in order to inactivate various microbes, synthesize new chemicals, speed separation of a mixture, and aid in oil extraction. Such a discharge may be repeated at an optimum duration and duty-cycle to maximize the chemical effects of the non-equilibrium plasma at a substantially lower temperature than for an equilibrium plasma.

Abstract: Hydrocarbon conversion and transportation methods and apparatuses are provided. An apparatus may apply electron beam irradiation to hydrocarbons (i.e., natural gas) to convert the hydrocarbons to liquid fuel. Lower-weight hydrocarbons may be converted into medium-weight organics through a gas to liquid process (GTL). The electrons may generate radicals that facilitate desired reactions. The hydrocarbons may be temperature and pressure controlled. For example, the hydrocarbons may be at lower temperatures (e.g., cryogenic or otherwise below ambient) and/or at higher pressures (e.g., greater than standard atmospheric pressures). Temperature suppression may reduce decomposition reactions. A high energy electron beam (e.g., 500 keV or higher, such as 10 MeV) could be used for the conversion process. The hydrocarbon may be liquefied. The liquid-like, higher density lower-weight hydrocarbons may lead to radical-neutral interactions. The high-energy electrons may penetrate the liquid hydrocarbon, treating more than just the surface of the liquid hydrocarbon.
