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.

International Classification:

F27B 14/00

US Classification:

219425000

Abstract:

Current industrial and research applications that utilize resistance heating and temperature measurement require separate power and temperature connections, typically two for each. Such applications require separate assemblies and control. We describe herein a combined unit utilizing a thermocouple wire as one of its two leads. The resulting device requires only two connections and one control. An alternating cycle can be used to apply heating power, and temperature measurements are made during the power off portion of the cycle.

International Classification:

B32B 5/16
H05H 1/24

US Classification:

428402, 427569, 977890

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.

US Classification:

252504, 252506, 252502, 252509, 427 77, 977775, 977890

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.

International Classification:

H05H 300

US Classification:

250251

Abstract:

A vacuum compatible hyperthermal atom generator includes a membrane having two sides, the membrane having the capability of dissolving atoms into the membrane's bulk. A first housing is furnished in operative association with the first side of the membrane to provide for the exposure of the first side of the membrane to a gas species. A second housing is furnished in operative association with the second side of the membrane to provide a vacuum environment having a pressure of less than 1. times. 10. sup. -3 Torr on the second side of the membrane. Exciting means excites atoms adsorbed on the second side of the membrane to a non-binding state so that a portion from 0% to 100% of atoms adsorbed on the second side of the membrane are released from the second side of the membrane primarily as an atom beam.

International Classification:

H05H 300

US Classification:

250251

Abstract:

A high purity, hyperthermal, continuous beam atomic oxygen source capable of retrofitting to existing UHV systems has been developed. The instrument complements a general system capability, while its small size and simplicity of design permits tailoring the instrument for most experimental geometries. The flux level presently available is near 1. times. 10. sup. 14 cm. sup. -2 s. sup. -1 (. sup. 3 P) but may be extended toward the theoretical limit of 3. times. 10. sup. 15 cm. sup. -2 s. sup. -1. The energy distribution of the emitted neutrals shows that the mean kinetic energy is about the same as observed for the ions or about 5 eV. The energy of the oxygen atoms may be substantially reduced for other applications by collision with a temperature controlled, non-reactive surface (with a concomitant spread in the energy distribution).

International Classification:

B01D 5332

US Classification:

423579

Abstract:

A method for producing an atomic oxygen beam is provided by the present invention. First, a material 10' is provided which dissociates molecular oxygen and dissolves atomic oxygen into its bulk. Next, molecular oxygen is exposed to entrance surface 11' of material 10'. Next, material 10' is heated by heater 17' to facilitate the permeation of atomic oxygen through material 10' to the UHV side 12'. UHV side 12' is interfaced with an ultra-high vacuum (UHV) environment provided by UHV pump 15'. The atomic oxygen on the UHV side 12' is excited to a non-binding state by exciter 14' thus producing the release of atomic oxygen to form an atomic oxygen beam 35'.
