Qhov sib txawv tseem ceeb ntawm buckyballs thiab nanotubes yog buckyballs muaj cov qauv globular nrog carbon atoms muaj peb daim ntawv cog lus nrog ib leeg, whereas nanotubes yog tubular qauv nrog peb daim ntawv cog lus ntawm carbon atoms.
Ob leeg Buckyballs thiab nanotubes yog cov qauv nanoscale. Lo lus buckyballs hais txog Buckminsterfullerene. Nanotubes yog ib hom raj ua los ntawm cov pa roj carbon atoms, thiab cov raj no muaj cov diameters feem ntau ntsuas hauv nanometers.
Buckyballs yog dab tsi?
Lo lus buckyballs hais txog Buckminsterfullerene. Nws yog ib hom fullerene nrog cov tshuaj formula C60. Cov khoom no yog lub tawb zoo li fused-ntiv nplhaib qauv uas zoo li zoo li football vim nws yog ua los ntawm 20 hexagons thiab 12 pentagons. Cov qauv no muaj cov pa roj carbon atom nrog peb daim ntawv cog lus nruab nrab ntawm lawv. Buckyballs tshwm li cov khib nyiab dub uas zoo li yaj hauv cov kuab tshuaj hydrocarbon, tsim cov tshuaj violet.
Daim duab 01: Cov qauv ntawm Buckyballs
Buckyballs tshwm sim ib txwm ua kom puv. Peb tuaj yeem pom qhov me me ntawm Buckyballs hauv cov kua qaub. Ntxiv mus, nws muaj nyob rau hauv qhov chaw, nyob rau hauv planetary nebulae, thiab nyob rau hauv ib co hnub qub. Raws li txoj cai, cov khoom no yog thawj zaug kwv yees hauv xyoo 1960 thiab 1970s. Nws yog thawj zaug tsim nyob rau hauv 1984 los ntawm Eric Rohfing, Donald Cox, thiab Andrew Kaldor. Lawv siv lub laser vaporize carbon nyob rau hauv lub supersonic helium beam.
Nws yog ib qho molecule ruaj khov uas tuaj yeem tiv taus qhov kub thiab txias. Nws yog qhov loj tshaj plaws paub molecule pom los nthuav tawm nthwv dej-particle dual mus txog 2020. Cov tshuaj ntawm Buckyballs feem ntau muaj cov xim sib sib zog nqus. Nws tawm xim av residue thaum evaporated. Qhov kev hloov xim no tshwm sim vim yog lub zog nqaim dav ntawm pawg ntawm cov qib molecular uas yog lub luag haujlwm rau lub teeb ntsuab absorbed los ntawm tus neeg C-60 molecules. Tsis tas li ntawd, cov khoom no yog me ntsis soluble hauv cov kuab tshuaj tsw qab thiab carbon disulfide. Tab sis nws yog insoluble hauv dej.
Nanotubes yog dab tsi?
Nanotubes yog ib hom raj ua los ntawm cov pa roj carbon atoms, thiab cov raj no muaj cov diameters feem ntau ntsuas hauv nanometers. Muaj ob hom nanotubes ua ib phab ntsa carbon nanotubes (SWCNTs) thiab ntau phab ntsa carbon nanotubes (MWCNTs).
The SWCNTs tuaj yeem piav qhia tias yog ib qho allotrope ntawm cov pa roj carbon uas yog qhov nruab nrab ntawm fullerene thiab tiaj graphene. Peb tuaj yeem ua qhov zoo tshaj plaws ntawm cov nanotubes li kev txiav tawm los ntawm 2D hexagonal lattice ntawm carbon atoms uas tau dov raws li ib qho ntawm Bravais lattice vectors ntawm hexagonal lattice, tsim ib lub tog raj kheej hollow.
Daim duab 02: Cov pa roj carbon nanotubes
Ntawm qhov tod tes, MWCNTs muaj cov nested ib leeg-phab ntsa carbon nanotubes uas tsis muaj zog ua ke los ntawm Van der Waals kev sib cuam tshuam hauv cov ntoo zoo li lub nplhaib. Qee zaum, peb tuaj yeem xa mus rau lawv li ob-thiab triple-phab ntsa carbon nanotubes.
Muaj qhov zoo tshaj plaws hluav taws xob conductivity los ntawm carbon nanotubes. Tsis tas li ntawd, lawv muaj qhov tshwj xeeb tensile lub zog thiab thermal conductivity. Qhov no yog vim lub nanostructure thiab lub zog ntawm kev sib txuas ntawm cov pa roj carbon atoms. Tsis tas li ntawd, peb tuaj yeem hloov kho cov nanotubes.
Dab tsi zoo sib xws ntawm Buckyballs thiab Nanotubes?
- Buckyballs thiab nanotubes yog nyob rau hauv nanoscale.
- Ob leeg muaj carbon atom nrog peb daim ntawv cog lus (ob daim ntawv cog lus thiab ib daim ntawv cog lus ob zaug).
Qhov txawv ntawm Buckyballs thiab Nanotubes yog dab tsi?
Ob leeg Buckyballs thiab nanotubes yog cov qauv nanoscale. Qhov sib txawv tseem ceeb ntawm buckyballs thiab nanotubes yog tias buckyballs muaj cov qauv globular nrog carbon atoms muaj peb daim ntawv cog lus nrog ib leeg, whereas nanotubes yog tubular cov qauv nrog ob daim ntawv cog lus thiab ib daim ntawv cog lus ob npaug ntawm txhua cov pa roj carbon atom.
Cov hauv qab no qhia txog qhov sib txawv ntawm buckyballs thiab nanotubes hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Buckyballs vs Nanotubes
Ob leeg Buckyballs thiab nanotubes yog cov qauv nanoscale. Lo lus buckyballs hais txog Buckminsterfullerene. Nanotubes yog ib hom raj ua los ntawm cov pa roj carbon atoms, thiab cov hlab no muaj cov diameters feem ntau ntsuas hauv nanometers. Qhov sib txawv tseem ceeb ntawm buckyballs thiab nanotubes yog tias buckyballs muaj cov qauv globular nrog carbon atoms muaj peb daim ntawv cog lus nrog ib leeg, whereas nanotubes yog tubular cov qauv nrog ob daim ntawv cog lus thiab ib ob daim ntawv cog lus ntawm txhua cov pa roj carbon atom.
