摘要： A method for manufacturing carbon nanotubes with an integrally attached outer graphitic layer is disclosed. The graphitic layer improves the ability to handle and manipulate the nanometer size nanotube device in various applications, such as a probe tip in scanning probe microscopes and optical microscopes, orbs an electron emitting device. A thermal chemical vapor deposition reactor is the preferred reaction vessel in which a transition metal catalyst with an inert gas, hydrogen gas and a carbon-containing gas mixture are heated at various temperatures in a range between 500° C. and 1000° C. with gases and temperatures being adjusted periodically during the reaction times required to grow the nanotube core and subsequently grow the desired outer graphitic layer.

摘要： A cold-cathode fluorescent lamp, comprising a sealed lighting enclosure provided with a phosphor coating on at least part of an inner surface thereof the lighting enclosure. An electrode is provided juxtaposed a region of the inner surface of the lighting tube, the electrode energisable from an external source of energy via an electric lead supporting the electrode, and positioned adjacent the main ionisation region within the lighting enclosure. The phosphor is to be excited by radiation to be generated inside the lighting tube by electric discharge from the electrode to provide visible radiation. At least part of the surface(s) of that portion of the electrode proximal most to the ionisation region are overlaid by a cap made from a high heat resistive and non conductive material.

摘要： Carbon nanoparticles including both nanofilaments and nanotubes produced by an electrochemical deposition method from organic solutions at room temperature, in which the formation and growth of carbon nanoparticles are stimulated by the catalyst, such as iron and nickel. It has been found that the electrochemical deposition conditions have a strong influence on the growth phenomenon of the carbon nanotubes. Scanning electron microscope (SEM) and transmitting electron microscope (TEM) characterizations show that the diameter of nanotubes is of the order of approximately 100 nm, and the length of filaments can be up to approximately 50 &mgr;m, depending on the size of catalyst particles.

摘要： A flash discharge lamp includes a pair of electrodes i.e. an anode and a cathode, oppositely disposed in at both ends of the glass bulb. An electro-conductive member is provided on the outer surface of the glass tube. A triggering electrode is mounted on the cathode and electrically connected to the electro-conductive member. Xenon gas is sealed in the glass tube. The flash discharge lamp further includes at least one High Temperature Resistant electrode mounted on the cathode and at least one Getter electrode mounted on the cathode and/or the anode. Not only can the above design increase the discharge output power and the discharge frequency, but it also extends the life expectancy of the flash discharge lamp.

摘要： A method is provided for growing a diamond thin film on a selected substrate. First the substrate is prepared by scratching the surface thereof with diamond paste. The substrate is then confined in an enclosed space which includes high purity hydrogen and high purity methane gasses under relatively low pressure. The substrate is then irradiated with microwave energy to subject the substrate to a plasma exhibiting a first predetermined power density for a first period of time sufficient to form, on the substrate, diamond-like ball structure particles. The power density of the plasma to which the substrate is exposed is then effectively increased to a second predetermined power density and the substrate in exposed to the plasma for a second period of time sufficiently long such that (100) diamond faces grow on top of the ball structure particles. Finally, the irradiation of the substrate with the diamond-like ball structure particles thereon is continued at the second predetermined power density for a third period of time sufficient to cause the (100) faces on top of the particles to be joined together into a substantially continuous diamond film.
