A gas concentration regulator for use in culture of anaerobic bacteria, including: (a) dehydroascorbic acid; (c) a transition metal catalyst; (d) activated carbon; (e) at least one selected from the group consisting of an alkali metal carbonate, an alkali metal hydroxide, and an alkaline earth metal hydroxide; and (f) water.

Agent for regulating concentration of gas for anaerobic bacterium culture and method for culturing anaerobic bacterium using same

An object of the invention is achieved by a method for producing a composite material, including the steps of combining a resin precursor and a reinforcing fiber and carrying out a polymerization reaction of the resin precursor. That is, a thermoplastic resin composite material having high strength can be obtained by the production method.

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.

Aligned carbon nanotube films and a process for producing them

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.

Process for producing cold field-emission cathodes

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.
