Ubwino wa SWCNTs ntchito Chimbudzi Chithandizo:
Ntchito: Chifukwa cha kusiyana kwake kwa mainchesi ake ndi ngodya ya helix, mpweya wa nanotube ukhoza kukhala chitsulo kapena semi-conductive.Chifukwa chake, atha kuyigwiritsa ntchito popanga diode yama cell, ndipo diode idzakhala yaying'ono ngati nanometer yomwe ndi yaying'ono kwambiri kuposa yapadziko lonse lapansi pano.Mpweya wa carbon nanotube uli ndi mphamvu zambiri, zomwe zimakhala zamphamvu kwambiri kuposa zitsulo.Pa nthawi yomweyi, carbon nanotube ndi yopepuka kwambiri, yomwe ndi gawo limodzi mwa magawo khumi a zitsulo.Ili ndi malingaliro abwino ogwiritsira ntchito pazinthu zophatikizika ndipo izikhala ndi chikoka chachikulu pazamlengalenga ndi ndege.
Carbon nanotube ili ndi ntchito yabwino kwambiri yotulutsa mpweya.Itha kugwiritsidwa ntchito popanga zida zowonetsera gulu lathyathyathya komanso m'malo mwa njira yayikulu komanso yolemetsa ya ma elekitironi ya cathode.Kupatula apo, mpweya wa nanotube ungagwiritsidwenso ntchito popanga mayendedwe a molekyulu ndi nano loboti.Ndizoyenera kugwiritsa ntchito ngati zinthu zosungira mphamvu monga kusungirako hydrogen.Mu njira zamankhwala, itha kugwiritsidwa ntchito ngati chidebe cha nano ndikukwaniritsa kuwongolera mlingo.
Mpweya nano-chubu ndi nano grade tubular graphite makhiristo, omwe amakhala ndi monolayer kapena multilayer flakegraphite yomwe imazungulira shaft yapakati molingana ndi ma spiral angle curly ndi kulowa mu chubu chopanda msoko.Chifukwa cha zomangamanga zapadera, zimakhala ndi zinthu zambiri zapadera ndipo zingagwiritsidwe ntchito pamagetsi, makina, mankhwala, mphamvu, mankhwala, optics ndi zina za sayansi ya zipangizo, komanso ntchito zomwe zingagwiritsidwe ntchito m'madera omangamanga.Amawonetsa mphamvu zodabwitsa komanso mawonekedwe apadera amagetsi, komanso ndi ma conductor otenthetsera bwino.
Mphamvu ndi kusinthasintha kwa ma carbon nanotubes amawapangitsa kuti azitha kugwiritsidwa ntchito poyang'anira zida zina za nanoscale, zomwe zikuwonetsa kuti adzakhala ndi gawo lofunikira muukadaulo wa nanotechnology.
