Cov txiaj ntsig zoo ntawm SWCNTS siv hauv dej phwj tuaj:
Daim Ntawv Thov: Vim qhov sib txawv ntawm nws cov cheeb thiab Helix Angle, cov pa roj carbon monoxide, cov pa roj carbon monoxide, cov pa roj carbon monoxide Yog li, tuaj yeem siv nws los ua cov molecular-teev diode, thiab cov diode yuav me li nanometer uas yog ntau me dua li lub universal ib qho tam sim no. Cov pa roj nanotube muaj lub zog siab tshaj plaws, uas muaj zog dua li cov hlau. Nyob rau tib lub sijhawm, cov pa roj carbon naniberube yog lub teeb heev hauv qhov hnyav, uas tsuas yog ib feem kaum ntawm cov hlau. Nws muaj cov kev xav tau zoo nyob hauv thaj teb ntawm cov khoom siv sib xyaw thiab yuav ua rau muaj kev cuam tshuam loj rau aerospace thiab aeronautics.
Cov Nanotube muaj cov teb zoo tshaj plaws emission kev ua tau zoo. Nws tuaj yeem siv nyob rau hauv kev ua vaj huam sib luag lub chaw ua haujlwm thiab hloov chaw loj thiab hnyav Cathade hluav taws xob cov txheej txheem. Dhau li, cov pa roj carbon nanotube tseem tuaj yeem siv ua molecule bearings thiab nano neeg hlau. Nws yog haum siv raws li lub zog cia khoom xws li hydrogen cia. Hauv cov txheej txheem tshuaj, nws tuaj yeem siv ua nano thawv thiab kom ua tiav kev tswj hwm cov tshuaj.
Cov pa roj carbon nano-raj yog lub nano qib tubular graphite muaju, uas muaj monolayer lossis multiilayer ntsuab rov qab raws li qee tus kheej kheej cylindrical raj. Vim tias kev tsim kho tshwj xeeb, nws muaj ntau yam khoom tshwj xeeb thiab tuaj yeem siv rau hauv cov khoom siv hluav taws xob, kho tshuaj, kho tshuaj, thiab lwm yam kev siv tshuaj txuj ci, nrog rau cov peev xwm siv hauv cov duab kos duab. Lawv nthuav tawm lub zog txawv tshaj plaw thiab cov hluav taws xob hluav taws xob, thiab ua cov thermalmer.
Lub zog thiab hloov cov pa roj carbon nanotubes ua rau lawv muaj peev xwm siv nyob rau hauv kev tswj hwm lwm cov qauv nanoscale cov qauv, uas qhia tias lawv yuav muaj lub luag haujlwm nanotecology.
