  • Patent number: 11642645
    Abstract: A system and method are provided for the separation of hydrogen from natural gas feedstock to form hydrocarbon radicals. Aspects of the system include perpendicular magnetic and electric fields, a method of radical formation that separates hydrogen from the reaction process, and a separation method based on centrifugal forces and phase transitions. The gases rotate in the chamber due to the Lorentz force without any mechanical motion. Rotation separates gases and liquids by centrifugal force. The lighter species are collected from the mid region endpoint of the apparatus and fed back for further reaction. A new concept of controlled turbulence is introduced to mix various species. A novel magnetic field device is introduced comprised of two specially magnetized cylinders. A novel control of temperatures, pressures, electron densities and profiles by, RF, microwaves, UV and rotation frequency are possible especially when atomic, molecular, cyclotron resonances are taken into account.

  • 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.

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.

The rate at which the plurality of ionized carbon atoms is produced is controlled to control the rate of graphene generation. The magnetic field of the magnetic structure can be controlled to control the rate at which the generated graphene moves through the graphene generation chamber until it exits as a recovered graphene product.

  • 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.

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.
