    摘要： There is provided a method of purifying single wall carbon nanotubes so as to be able to remove impurities such as a metal catalyst to obtain the single wall carbon nanotubes with high purity. The method includes the first oxidizing step of oxidizing the single wall carbon nanotubes soot 1 containing an impurity with a metal catalyst 2, the first refluxing step of refluxing the single wall carbon nanotubes soot 1 obtained by the first oxidizing step in an acid solution, the second oxidizing step of oxidizing the single wall carbon nanotubes soot 1 obtained by the first refluxing step, and the second refluxing step of refluxing the single wall carbon nanotubes obtained soot 1 by the second oxidizing step in an acid solution. The single wall nanotubes 1 are synthesized by an arc discharge with a carbon electrode containing a metal catalyst 2. The carbon electrode contains a metal catalyst which consists of Ni, Y, and Ti. The first oxidizing step is performed by heating at a temperature between 350 and 600° C. or by a wet-oxidization in hydrogen peroxide solution. The first refluxing step is performed by refluxing in nitric acid. The second oxidizing step is performed by wet-oxidizing in hydrogen peroxide. The second refluxing step is performed by refluxing in hydrochloric acid.

    摘要： A hydrogen storage tank comprises a hydrogen adsorbent accommodated in a pressure-resistant container. The hydrogen adsorbent is capable of adsorbing and retaining hydrogen gas of a volume exceeding an occupation volume occupied by the hydrogen adsorbent itself. As for the hydrogen adsorbent, the amount of endothermic heat, which is generated when the adsorbed hydrogen gas is released, is not more than 16 kJ per mol of hydrogen molecules. The hydrogen adsorbent is prevented from leaking outside of the pressure-resistant container by a filter.

    摘要： Carbon structures, e.g. carbon nano-fibers, suitable for absorbing hydrogen at low pressures and low temperatures are produced by a selective oxidation and/or acid reflux process. The process includes heating an impure mixture containing a crystalline form of carbon in the presence of an oxidizing gas at a temperature and time sufficient to selectively oxidize and remove a substantial amount of any amorphous carbon impurities from the mixture. Metal containing impurities can be removed from the mixture by exposing the desired carbon and accompanying impurities to an acid to produce a carbon fiber that is substantially free of both non-fiber carbon impurities and metal impurities. Another aspect of the present invention includes purified carbon structures that can store hydrogen at low pressures and temperatures.

A nucleus generation site is disposed on a substrate 6. The first material gas is fed to the nucleus generation site to form a wire-like semiconductor 2a in the nucleus generation site. A second material gas to the fourth material gas are fed to form the wire-like semiconductor 3 on the semiconductor 2a, the wire-like semiconductor 4 on the semiconductor 3, and the wire-like semiconductor 5 on the semiconductor 4. The bandgaps of the semiconductors decrease and increase consistently with the distance to the substrate 2 or 6. The nucleus generation site is made of catalytic particles such as Au.

    摘要： A gas cooking stove is disclosed to which a very-small gas cylinder is joined in a one-touch manner and the state of joining is reliably maintained. When the gas cooking stove is used, the gas cooking stove can stably be installed. When the gas cooking stove is not used, the overall size can be reduced to save the space. Thus, the operability, safety and the portability can be improved. A valve mechanism, an operation member for opening/closing the valve mechanism and a piezoelectric spark unit are provided. Moreover, a stove body is provided which has an upper portion to which a dish is joined and a lower portion provided with a gas-cylinder joining portion to which a gas cylinder is joined. A grate is rotatively supported by the dish. The gas cylinder having a valve-joining cylindrical portion which is integrally formed with the gas cylinder, which accommodates a valve mechanism, in which the valve mechanism is secured and from which a stem is allowed to project over the valve-joining cylindrical portion is joined to the gas-cylinder joining portion in the one-touch manner. The gas cylinder has the valve-joining cylindrical portion which is held by a cylinder holding member.
