Applications of dielectric barrier discharge (DBD) based atmospheric pressure plasma jets are often limited by the relatively small area of treatment due to their 1D configuration. This system generates 2D plasma jets permitting fast treatment of larger targets. DBD evolution starts with formation of transient anode glow, and continues with development of cathode-directed streamers. The anode glow can propagate as an ionization wave along the dielectric surface through and outside of the discharge gap. Plasma propagation is not limited to 1D geometry such as tubes, and can be organized in a form of a rectangular plasma jet, or other 2D or 3D shapes. Also described are a method for generating 2D plasma jets and use of the 2D plasma jets for cancer therapy.

Method of generation of planar plasma jets

Disclosed herein are atmospheric pressure pin-to-hole pulsed spark discharge devices and methods for creating plasma. The devices include a conduit for fluidically communicating a gas, a plasma, or both, therethrough, portion of the conduit capable of being connected to a gas supply, and a second portion of the conduit capable of emitting a plasma; a positive electrode comprising a sharp tip; and a ground plate electrode. Disclosed are methods for treating a skin ulcer using non-thermal plasma include flowing a gas through a cold spark discharge zone simultaneously with the creation of a pulsed spark discharge to give rise to a non-thermal plasma emitted from a conduit, the non-thermal plasma comprising NO; and contacting a skin ulcer with said non-thermal plasma for sufficient time and intensity to give rise to treatment of the skin ulcer.

Apparatus for atmospheric pressure pin-to-hole spark discharge and uses thereof

The present invention provides a method of incorporating a gaseous hydrocarbon into a liquid hydrocarbon. The method comprises steps of exposing a gaseous hydrocarbon to non-thermal plasma generated using a reduced electric field with an E/N ratio in a range of from about 10 to about 30 Td to activate the gaseous hydrocarbon, and contacting the activated gaseous hydrocarbon with the liquid hydrocarbon to incorporate the gaseous hydrocarbon into the liquid hydrocarbon. The method provides the advantages of low energy consumption and relatively low capital expenditure.

Direct incorporation of natural gas into hydrocarbon liquid fuels

Aspects of the present subject matter are directed to a method comprising contacting an fluid, optionally containing an added organic material, with a non-thermal plasma to form a disinfection composition, wherein the disinfection composition is a liquid, and contacting a surface with the disinfection composition, wherein the surface is at least partially disinfected upon contact with the disinfection composition. Additional aspects of the present subject matter are directed to a method comprising forming a disinfection composition by contacting an organic material with a non-thermal plasma, wherein the disinfection composition is a liquid. A further aspect of the present subject matter is directed to a disinfection composition comprising an organic material contacted by a non-thermal plasma, wherein the disinfection composition is a liquid.

Materials for disinfection produced by non-thermal plasma

Non-thermal plasma is a partly ionized gas, which can be generated by a high-voltage electric field at a low pressure. Disclosed herein are apparatuses and methods for treating an enteric disease in vivo using non-thermal plasma. The disclosed apparatuses have a first conduit comprising a lumen and a tip; a first electrode disposed within the lumen of the first conduit; a second electrode comprised of a metal conduit disposed within the first conduit; an insulator disposed within the lumen of the first conduit, the insulator configured to electrically insulate the first electrode from the second electrode; and a gas channel disposed between the outer surface of the metal conduit and the inner surface of the first conduit, the gas channel being capable of feeding a gas from a gas source to the tip, wherein when the potential is applied, the gas is ionized to produce the non-thermal plasma.
