  • Patent number: 9023214
    Abstract: The invention provides a method and apparatus for creating plasma particles and applying the plasma particles to a liquid. Liquid feedstock (e.g., water and/or hydrocarbons mixed with biomass) is pumped through a pipeline; the single-phase stream is then transformed into a biphasic liquid-and-gas stream inside a chamber. The transformation is achieved by transitioning the stream from a high pressure zone to a lower-pressure zone. The pressure drop may occur when the stream further passes through a device for atomizing liquid. Inside the chamber, an electric field is generated with an intensity level that exceeds the threshold of breakdown voltage of the biphasic medium leading to a generation of a plasma state. Furthermore, the invention provides an energy-efficient highly adaptable and versatile method and apparatus for sanitizing water using plasma particles to inactivate biological agents contaminating water.

    Abstract: A system providing selective spin modification and reaction in an electrolytic cell. An electrolytic cell is coupled to a magnet that provides a level-splitting magnetic field in a region of electrolyte adjacent to a working electrode, thus establishing a spin resonance for an unpaired electron associated with a chemical species in the region of electrolyte adjacent to the working electrode. The working electrode carries an excitation current produced by a switching source or amplifier. The excitation current produces an alternating magnetic field adjacent to the working electrode that alters the spin state population density for the unpaired electron associated with a chemical species within the electrolyte, thereby enhancing or inhibiting the reaction of the chemical species during subsequent electrolysis.

    Abstract: A hydrogen storage and recovery system includes a substrate having embedded hydrogen molecules and a grid of cells. Each cell includes an electron source for directing electrons onto the substrate, two orthogonal magnetic or electric fields that are oriented so that the electrons pass through both magnetic fields prior to striking the substrate, and an ion guide. A voltage source establishes a potential for the electrons that is equal to the ionization potential of the hydrogen molecules, so that hydrogen molecules are ionized when the electrons impinge on the substrate. The magnetic fields can be manipulated to deflect, or change, the direction of said electrons passing through the fields, so that electrons strike the substrate at different locations, which allows for more recovery of the embedded hydrogen molecules from the substrate. The ion guide uses an applied electric field to draw hydrogen ions that have been ionized for subsequent storage.

  • Patent number: 8021521
    Abstract: A method of processing a workpiece in a plasma reactor having an electrostatic chuck for holding a workpiece in a chamber of the reactor includes providing a thermally conductive gas under pressure between a backside of the workpiece and a top surface of the electrostatic chuck, controlling the temperature of the electrostatic chuck, defining a desired workpiece temperature, measuring a current workpiece temperature or temperature related to the workpiece temperature and inputting the measured temperature to a thermal model representative of the electrostatic chuck. The method further includes determining from the thermal model a change in the pressure of the thermally conductive gas that would at least reduce the difference between the measured temperature and the desired temperature, and changing the pressure of the thermally conductive gas in accordance with the change determined from the thermal model.

  • Patent number: 7767062
    Abstract: Provided is a submerged-type, electrosorption-based desalination apparatus for water purification and method, comprising applying a DC voltage of 0.1 to 2.0 volts to a carbon electrode of the reactor to thereby adsorb inorganic ions on the carbon electrode, and reversely applying the same DC voltage having opposite polarity to recycle regeneration solution to the outside of the apparatus or into the treatment tank, thereby enhancing a recovery rate. In addition, in order to improve desalination efficiency, the reactor used in the desalination apparatus may be embodied in various forms of T-shaped, linear type, single, composite, and ion exchange membrane electrodes. Therefore, the present invention may be applied to remove inorganic ions from industrial wastewater, sea water, and brackish water, which contain large amounts of inorganic ions.

  • Publication number: 20090308729
    Abstract: An apparatus and method for hydrogen production by dissociating water molecules in response to plasma output from a plasma source. This plasma source can have an RF antenna, capable of operating in capacitive, inductive, or helicon mode when operating conditions match those required to excite these modes. Hydrogen is produced by injecting water vapor into the plasma source. According to the principles of the present teachings, the apparatus and method are, thus, capable of dissociating water molecules into their constituent species.

  • Patent number: 7615931
    Abstract: A dielectric barrier plasma discharge device consistent with certain embodiments of the present invention has a pair of electrodes spaced apart by an electrode gap. A dielectric is disposed between the electrodes. The electrode gap is provided with a gas at a specified pressure. A rapid rise time voltage pulse generator produces a voltage pulse across the electrodes to cause an extreme overvoltage condition, wherein the rapid rise time is less than a plasma generation time so that the extreme overvoltage condition occurs prior to current flow across the electrode gap. Due to the high voltages and high current densities, the product yields an extremely high instantaneous power density. This extreme overvoltage condition is also believed to lead to production of shock waves and runaway free electrons. The resulting plasma can be utilized to carry out many potential tasks including, but not limited to etching, deposition, and sterilization.

  • Publication number: 20080296143
    Abstract: Plasma systems with magnetic filter devices to alter film deposition/etching characteristics by altering the effective magnetic field distribution. The magnetic filter devices are placed between the magnet or magnets and a target, typically a semiconductor wafer, and selected and configured to alter the magnetic field to obtain the desired processing results. For deposition, the magnetic filter may be chosen to provide more uniform deposition, to provide increased deposition rates at or adjacent the edges of a wafer to compensate for increased etching rates at the edges of a wafer in a subsequent etching or polishing process. For annealing and doping, the magnetic field may be altered to provide more uniform equivalent annealing or doping across the wafer. Various applications are disclosed.
