Abstract
(EN)
A system is provided that can be utilized to generate nanotubes with substantially similar chirality. The system provides a resonant frequency, keyed to a desired radial breathing mode linked to the desired chirality, that causes a template of catalysts particles or nanotubes to oscillate at the provided resonant frequency, so as to stimulate growing nanotubes to oscillate at a corresponding resonant frequency. This resonant frequency can be a result of a high frequency field or the natural heat radiation generated by the system.
(FR)
L'invention concerne un système permettant de produire des nanotubes présentant une chiralité sensiblement similaire. Ce système produit une fréquence de résonance réglée sur un mode de respiration radial recherché, associé à la chiralité recherchée, qui provoque l'oscillation d'une matrice de particules de catalyseur ou de nanotubes à la fréquence de résonance produite, afin de stimuler les nanotubes en cours de formation pour qu'ils oscillent à la fréquence de résonance correspondante. Cette fréquence de résonance peut résulter d'un champ haute fréquence ou du rayonnement thermique naturel généré par le système.
