20090261186 | ELECTROSTATIC ATOMIZING FUEL INJECTOR USING CARBON NANOTUBES - Use of carbon nanotubes (CNTs) in a charge injector to assist in atomizing fuel for engine applications. A CNT charging unit is positioned in front of a fuel injector. A voltage is applied on a CNT coated mesh to charge the fuel stream when it passes. Then the charged stream goes through a grounded metal cage. The fuel is thereby electrostatically charged causing repulsive forces on surfaces of liquid in the fuel resulting in the liquid splitting into droplets. | 10-22-2009 |

20100102245 | PHOTOCATHODE WITH NANOMEMBRANE - Optical beam modulation is accomplished with the aid of a semiconductive nanomembrane, such as a silicon nanomembrane. A photocathode modulates a beam of charged particles that flow between the carbon nanotube emitter and the anode. A light source, or other source of electromagnetic radiation, supplies electromagnetic radiation that modulates the beam of charged particles. The beam of charged particles may be electrons, ions, or other charged particles. The electromagnetic radiation penetrates a silicon dioxide layer to reach the nanomembrane and varies the amount of available charge carriers within the nanomembrane, thereby changing the resistance of the nanomembrane. As the resistance of the nanomembrane changes, the amount of current flowing through the beam may also change. | 04-29-2010 |

20150040388 | Application of Dielectric Layer and Circuit Traces on Heat Sink - A dielectric layer is directly applied onto the surface of a heat sink part. For example, the composition for making the dielectric layer may be made into a paste or ink and then printed as a paste or ink, or applied with some other equivalent method, such as a lamination technique. The electrical circuit traces are then printed in a similar fashion onto the dielectric layer in the required pattern for whatever circuitry is to be applied. That circuitry (e.g., circuit elements) is then attached to the electrical traces as needed for the particular application. | 02-12-2015 |
