Abstract: An apparatus and method are described for producing and harvesting algae. The orientation of the production substrates is critical for maximizing production as a function of water area utilized. By employing an array of algae production substrates in a vertical configuration relative to the water surface, the yield of algae production per area of open water is increased substantially relative to prior art algae production systems.

Abstract: Carbon nanoflakes, methods of making the nanoflakes, and applications of the carbon nanoflakes are provided. In some embodiments, the carbon nanoflakes are carbon nanosheets, which are less than 2 nm thick. The carbon nanoflakes may be made using RF-PECVD. Carbon nanoflakes may be useful as field emitters, for hydrogen storage applications, for sensors, and as catalyst supports.

Abstract: Compositions of carbon nanoflakes are coated with a low Z compound, where an effective electron emission of the carbon nanoflakes coated with the low Z compound is improved compared to an effective electron emission of the same carbon nanoflakes that are not coated with the low Z compound or of the low Z compound that is not coated onto the carbon nanoflakes. Compositions of chromium oxide and molybdenum carbide-coated carbon nanoflakes are also described, as well as applications of these compositions. Carbon nanoflakes are formed and a low Z compound coating, such as a chromium oxide or molybdenum carbide coating, is formed on the surfaces of carbon nanoflakes. The coated carbon nanoflakes have excellent field emission properties.

Abstract: Silicon oxynitride compositions are described herein. These compositions are typically deposited onto substrates using a nitrogen plasma-based, reactive sputtering method. Depending on their composition, these coatings can be used for field emission suppression, dielectric applications, reflection control, and surface passivation.

Abstract: Novel compositions and morphologies of carbon nanoflakes are described, as well as methods for making carbon nanoflakes using a radio frequency plasma enhanced chemical vapor deposition (RF-PECVD) process. Acetylene is used as a CVD source gas. By utilizing high concentrations of acetylene in the CVD source gas at relatively low temperatures, carbon nanoflake growth rate and robustness are improved, and the resulting carbon nanoflakes have enhanced height uniformity.

Abstract: A microwave-driven ultraviolet (UV) light source is provided. The light source comprises an over-moded microwave cavity having at least one discharge bulb disposed within the microwave cavity. At least one magnetron probe is coupled directly to the microwave cavity.

Abstract: An rf capacitively-coupled electrodeless light source is provided. The light source comprises a hollow, elongated chamber and at least one center conductor disposed within the hollow, elongated chamber. A portion of each center conductor extends beyond the hollow, elongated chamber. At least one gas capable of forming an electronically excited molecular state is contained within each center conductor. An electrical coupler is positioned concentric to the hollow, elongated chamber and the electrical coupler surrounds the portion of each center conductor that extends beyond the hollow, elongated chamber. A rf-power supply is positioned in an operable relationship to the electrical coupler and an impedance matching network is positioned in an operable relationship to the rf power supply and the electrical coupler.

Abstract: A plasma gun is described which is capable of creating and directing a plasma towards a neutralizing plate. The plate is comprised of a material which is chemically inert, metallic, and whose atoms are substantially heavier than the atoms of the plasma gas. The plasma, upon impacting the neutralizing plate, picks up sufficient electrons to cause the ions to revert to their neutral state. The particles, upon hitting the neutralizing plate, are redirected towards a substrate whose surface is to be altered or eroded. A potential may be applied to the neutralizing plate to enable the energy of the reflected particles to be controlled. The neutral atoms, so redirected, provide a desired anisotropic erosion capability.

Abstract: A method of treating the interior surfaces of a waveguide to improve power transmission comprising the steps of mechanically polishing to remove surface protrusions; electropolishing to remove embedded particles; ultrasonically cleaning to remove any residue; coating the interior waveguide surfaces with an alkyd resin solution or electrophoretically depositing carbon lamp black suspended in an alkyd resin solution to form a 1.mu. to 5.mu. thick film; vacuum pyrolyzing the film to form a uniform adherent carbon coating.
