摘要:
A carbon nanotube production method forms a carbon nanotube aggregate having a high perpendicular orientation characteristic where a plurality of carbon nanotubes are aligned in a direction perpendicular to a surface of a substrate, without using terpineol, which is a viscosity improver. A catalyst solution having a predetermined concentration (from 0.2 M to 0.8 M) of a transition metal salt dissolved therein, and free of terpineol is prepared. Catalyst particles are caused to be present on the surface of the substrate by making the catalyst solution contact with the surface of the substrate. By making a carbon nanotube forming gas contact with the surface of the substrate in a carbon nanotube forming temperature region, the carbon nanotube aggregate is grown on the surface of the substrate where a plurality of carbon nanotubes are aligned in the direction perpendicular to the surface of the substrate.

Disclosed is a composite carbon having a novel structure. This composite carbon has fibrous carbon which extends in the direction of the long axis, and multiple carbon nanotubes which are formed on the surface of the fibrous carbon and have a smaller diameter than the diameter of the fibrous carbon. The carbon nanotubes are formed as a group of multiple carbon nanotubes, with the lengthwise directions of each of the carbon nanotubes aligned in the same direction.

Provided is a method for producing lilies containing a blue pigment (delphinidin) in the petals thereof by introducing a foreign gene into lilies. The method pertaining to the present invention is a method for producing lilies containing delphinidin in the petals thereof, including the following steps: introducing, into a lily, a F3′5′H gene derived from a campanula and comprising a nucleotide sequence encoding a peptide having flavonoid 3′5′-hydroxylase (F3′5′H) activity, such as a nucleotide sequence represented by SEQ ID NO: 1 or SEQ ID NO: 11; while also introducing a F3′H gene fragment derived from a lily and comprising a nucleotide sequence encoding a peptide having flavonoid 3′-hydroxylase activity, such as a nucleotide sequence represented by SEQ ID NO: 3 or SEQ ID NO: 16; and inhibiting the expression of endogenous F3′H expression, which acts on cyanidin synthesis in lily petals, while the F3′5′H gene that has been introduced acts to cause the synthesis of delphinidin.
