    摘要: A carbon nanotube layer for a field emission cathode where individual carbon nanotubes or small groups of carbon nanotubes that stick out from the surface more than the rest of the layer are avoided. Electron fields will concentrate on these sharp points, creating an enhanced image on the phosphor, resulting in a more luminous spot than the surroundings. Activation processes further free such carbon nanotubes or groups of carbon nanotubes sticking out from the surface, exasperating the problem.

    摘要: A high voltage driver with capacitive coupling that is useful in the presence of the high power supply ripple common with higher-voltage systems. It permits extreme ranges of duty cycle, but without the limitations of transformer magnetics, or the increased complexity of optical coupling methods. It is also robust in the presence of voltage transients created by high-voltage arcing to the output drive-line.

    摘要: The present invention provides for variable-range hydrogen sensors and methods for making same. Such variable-range hydrogen sensors comprise a series of fabricated Pd—Ag (palladium-silver) nanowires—each wire of the series having a different Ag to Pd ratio—with nanobreakjunctions in them and wherein the nanowires have predefined dimensions and orientation. When the nanowires are exposed to H2, their lattace swells when the H2 concentration reaches a threshold value (unique to that particular ratio of Pd to Ag). This causes the nanobreakjunctions to close leading to a 6–8 orders of magnitude decrease in the resistance along the length of the wire and providing a sensing mechanism for a range of hydrogen concentrations.
