    Abstract: A method of recovering an organic decomposition product from an organic source may include: a) causing an inert gas to flow through the reduction zone from a reduction inlet to a reduction outlet in such a way that pressure in the reduction zone is maintained above ambient pressure of a local environment for the material recovery system and b) applying electromagnetic wave energy to the organic source in the reduction zone via a bifurcated waveguide assembly in the substantial absence of oxygen to produce at least one gaseous organic decomposition product in the reduction zone that is exhausted from the reduction zone along with the inert gas through the reduction outlet. A material recovery system may include a housing with an inert gas inlet, a reduction zone, and a reduction outlet, an inert gas supply, an electromagnetic wave generator, a bifurcated waveguide assembly, and a controller.

  • Patent number: 8425735
    Abstract: A method of fabricating pillared graphene assembles alternate layers of graphene sheets and fullerenes to form a stable protostructure. Energy is added to the protostructure to break the carbon-carbon bonds at the fullerene-to-graphene attachment points of the protostructure and allow the bonds to reorganize and reform into a stable lower energy unitary pillared graphene nanostructure in which open nanotubes are conjoined between graphene sheets. The attachment points may be functionalized using tether molecules to aid in attachment, and add chemical energy to the system. The arrangement and attachment spacing of the fullerenes may be determined using spacer molecules or an electric potential.

  • Publication number: 20130087446
    Abstract: A method of producing exfoliated graphite or graphene from a graphitic or carbonaceous material. The method includes: (a) dispersing a graphitic material in a liquid intercalating agent to form a suspension; and (b) subjecting the suspension to microwave or radio frequency irradiation for a length of time sufficient for producing the exfoliated graphite or graphene. In one preferred embodiment, the intercalating agent is an acid or an oxidizer, or a combination of both. The method enables production of more electrically conducting graphene sheets directly from a graphitic material without going through the chemical intercalation or oxidation procedure. The process is fast (minutes as opposed to hours or days of conventional processes), environmentally benign, and highly scalable.

  • Publication number: 20130048486
    Abstract: A method is disclosed for the treatment of a liquid, in particular a mineral oil, for increasing the portion of low-boiling fractions. The treatment comprises generating pressure waves having a first frequency, subjecting the liquid to said pressure waves in a region of application and feeding the so-treated liquid to a tank. At least one pipe flowed through by the treated liquid and immediately following said region of application is excited to oscillations of a second frequency, which is the resonance frequency of the excited system.

  • Patent number: 8317983
    Abstract: Single walled carbon nanotubes are produced in a novel apparatus by the laser-induced ablation of moving carbon target. The laser used is of high average power and ultra-fast pulsing. According to various preferred embodiments, the laser produces and output above about 50 watts/cm2 at a repetition rate above about 15 MHz and exhibits a pulse duration below about 10 picoseconds. The carbon, carbon/catalyst target and the laser beam are moved relative to one another and a focused flow of “side pumped”, preheated inert gas is introduced near the point of ablation to minimize or eliminate interference by the ablated plume by removal of the plume and introduction of new target area for incidence with the laser beam. When the target is moved relative to the laser beam, rotational or translational movement may be imparted thereto, but rotation of the target is preferred.
