Abstract: L1 is a maximum distance across a non-contacting section between intersection points of a straight line crossing the non-contacting section in parallel with an alignment direction of a carbon nanotubes in a plan view of a mounting section with a border between the non-contacting section and a contacting section. L2 is a maximum distance across the non-contacting section between intersection points of a straight line crossing the non-contacting section and intersecting the alignment direction of the carbon nanotubes in the plan view of the mounting section with the border between the non-contacting section and the contacting section. When L1 is larger than L2, at least L2 is more than 0 mm and less than 10 mm. When smaller, at least L1 is more than 0 mm and less than 10 mm. When equal, L1 and L2 are each more than 0 mm and less than 10 mm.

Abstract: The present invention provides a method for producing a carbon nanotube sheet that is excellent in light transmittance and conductivity, and the carbon nanotube sheet. The method includes firstly modifying of modifying a free-standing unmodified carbon nanotube sheet in which a plurality of carbon nanotubes are aligned in a predetermined direction. The firstly modifying includes performing a densification process of bringing the unmodified carbon nanotube sheet into contact with either one of or both of vapor and liquid particles of a liquid substance to produce a modified carbon nanotube sheet that contains the carbon nanotubes which are mainly aligned in a predetermined direction, and that includes a high density portion where the carbon nanotubes are assembled together and a low density portion where density of the carbon nanotubes is relatively lower than density in the high density portion.

Abstract: Nerve scaffolds are described that include a tubular outer housing fabricated from a biocompatible polymer, within which are disposed a plurality of carbon nanofiber yarns. The carbon nanofiber yarns, which can be separated by distances roughly corresponding to an average nerve fiber diameter, provide surfaces on which nerve fibers can regrow. Because the proximate carbon nanofiber yarns can support individual nerve fibers, a nerve can be regenerated with a reduced likelihood of undesirable outcomes, such as nerve pain or reduced nerve function.

Abstract: A carbo nanofiber nerve scaffold includes a cylindrical helix, a bundle of aligned carbon nanofiber yarns, and a carbon nanofiber sheet. The cylindrical helix includes a surgical suture material, and the cylindrical helix defines an interior of the carbon nanofiber nerve scaffold. The bundle of aligned carbon nanofiber yarns is disposed within the interior of the cylindrical helix. The carbon nanofiber sheet is disposed around the cylindrical helix on a side of the cylindrical helix opposite of the interior.
