▎ 摘 要
NOVELTY - Nanosynthesis apparatus (10) comprises: an outer tube (12) having an internal surface; an inner tube (14) at least partially disposed within the outer tube, where the inner tube has an external surface that opposes the internal surface of the outer tube across a gap (30); a deposition fluid source in fluid communication with the gap; and a heater (16) arranged to heat at least a portion of the gap during operation of the apparatus. USE - The nanosynthesis apparatus is useful for nanosynthesizing carbon nanotubes and graphene (claimed). ADVANTAGE - The apparatus is capable of operating at larger pressure differentials and synthesizing carbon nanotubes and graphene in an industrial manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for nanosynthesizing carbon nanotubes and graphene comprising (a) placing a growth substrate in a reaction chamber having an annular cross-section, and (b) flowing the deposition fluid through at least a portion of the reaction chamber in an axial direction, where a constituent of the fluid is deposited along the growth substrate as part of a nanostructure. DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of a nanosynthesis apparatus. Nanosynthesis apparatus (10) Outer tube (12) Inner tube (14) Heater (16) Gap. (30)
