  • Publication number: 20220256682
    Abstract: 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.

  • Patent number: 10308885
    Abstract: 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.

  • Patent number: 10167209
    Abstract: A treatment system for treating water, such as produced water that is produced during hydraulic fracturing. The system employs a combination of a plasma spark discharge and an RF oscillating electric field. The plasma spark discharge and the RF oscillating electric field may be employed simultaneously or in an overlapping manner within a chamber to treat the water. The treatment system is able to kill microorganisms as well as reduce or eliminate fouling due to, for example, bicarbonates. In some embodiments, grids are employed to further enhance the heat produced by the RF oscillating electric field.

  • Patent number: 10098687
    Abstract: The present invention is direct to a nano-probe corona tool and uses thereof. A nano-probe corona tool is disclosed having a tip with a diameter in the nano-scale, typically around 100 nm. The nano-probe corona tool is constructed of electrically conductive material. On the other end of the tool, a pulsed voltage source outputs a pulsed voltage to generate a pulsed electrical potential at the tip. The pulsed electrical potential at the tip causes a plasma discharge corona to occur. Uses of the corona discharge include, but are not limited to, optical emission spectroscopy, in the enhancement of deposition of coatings and nanoscale welding, e.g., nanotube or nanowires to a contact pad and welding two nanowires together, and in nanoscale surgery. For example, a nano-probe comprising CNTs may be inserted into cell membranes. The resulting corona discharge may be used to destroy tumors within the cell.

  • Patent number: 9834442
    Abstract: A reactor for reforming a liquid hydrocarbon fuel, and associated processes and systems, are described herein. In one example, a two stage process is disclosed in which a first reactor is coupled to a second stage reactor having a reaction volume greater than the first reactor. In the first reactor, the liquid hydrocarbon fuel is partially reformed and thereafter is inputted into the second stage reactor for complete partial oxidation. The reaction product is at last partially synthesis gas, a mixture of carbon monoxide, hydrogen, as well as other low hydrocarbons such as methane, ethylene, ethane, and acetylene. The low hydrocarbons can be reformed further in a solid oxide fuel cell. A portion of the gaseous, rotating contents of the second stage reactor may be input into the first reactor to help generate and sustain rotation within the first reactor.
