Abstract: Provided is an oxygen absorber containing: a liquid oligomer of an unsaturated hydrocarbon; a transition metal catalyst; a carrier supporting the liquid oligomer of the unsaturated hydrocarbon and the transition metal catalyst; granular activated carbon; and crystalline thermoplastic resin particles. In an analysis curve derived by subjecting the crystalline thermoplastic resin particles and the granular activated carbon to a pyrolysis-gas chromatography analysis under a pyrolysis condition of 600° C., a ratio [Cref/Pref] of a peak area (Cref) of a decomposition product of a low molecular weight component of the crystalline thermoplastic resin particles adsorbed on the granular activated carbon per unit mass of the activated carbon to a peak area (Pref) of the crystalline thermoplastic resin particle decomposition product per unit mass of the crystalline thermoplastic resin particles is 0.20 or less.

Abstract: Fine catalyst particles are loaded on a sol-gel method porous carrier having fine pores of 0.1-50 nm and a carbon compound is decomposed to form a carbon nanotube film on the carrier that is aligned perpendicular to the carrier surface. The starting sol to be processed by a sol-gel method is a dispersion of fine alumina particles, fine aluminum hydroxide particles, fine silica particles or mixtures thereof. Alternatively, the starting sol may be an aluminum alkoxide, an alkoxysilane, a mixture thereof or a solution of an aluminum alkoxide, an alkoxysilane or a mixture thereof. If desired, a flammable or a thermally decomposable organic compound may be added as a microporous template.

Abstract: A process for producing a cold field-emission cathode by patterning an aligned carbon nanotube film on a surface of a substrate for electrode, comprising the steps of preparing an aligned carbon nanotube film on a surface of a basic substrate, patterning a conductive binder on a surface of a substrate for electrode, and bonding a surface of the aligned carbon nanotube film to a surface of the conductive binder and then transferring the aligned carbon nanotube film by stripping the basic substrate, leaving those portions of the aligned carbon nanotube film behind which have been bonded to the conductive binder.

Abstract: A process for producing aligned carbon nanotube films, wherein a carbon compound is decomposed using a substrate that is coated with an element having no catalytic ability by itself and which loads a metallic element having catalytic ability or a compound thereof, thereby forming a film of fine carbon nanotubes on the surface of the substrate which are aligned in a direction perpendicular to the substrate.
