Yini Eyenza I-Fullerene C60 Ibe Yingqayizivele
Uma ubheka I-Fullerene C60, ubona i-molecule ebunjwe njengebhola lezinyawo. Ama-athomu e-carbon angamashumi ayisithupha ahlangana ndawonye ngendlela yama-pentagon nama-hexagon. Lesi simo esikhethekile sinikeza i-molecule amandla amakhulu, ibhalansi, kanye nokuzinza. Ososayensi nonjiniyela bayayisebenzisa ezindaweni eziningi ngenxa yalezi zimfanelo.
Izinto Ezibalulekile Okufanele Uzicabangele
- I-Fullerene C60 inesimo sebhola lezinyawo esiyingqayizivele esenziwe ngama-athomu ekhabhoni angu-60, enikeza amandla nokuqina.
- Ukulingana kwayo okuphezulu kuvumela ukusetshenziswa okuhlukahlukene kwezokwelapha, izinto zikagesi, kanye nesayensi yezinto zokwakha, okwenza kube yi-molecule ewusizo.
- I-Fullerene C60Ikhono lokumunca ukukhanya nokusebenza njenge-electron acceptor lithuthukisa ukusetshenziswa kwalo kumaseli elanga kanye nobuchwepheshe obuthuthukisiwe.
I-Fullerene C60 Isakhiwo sama-molecular
Ukuma kwe-Buckyball kanye nokuhlelwa kwe-athomu
Uma ubheka I-Fullerene C60, ubona i-molecule ebukeka njengebhola lezinyawo. Lesi simo sibizwa ngokuthi "i-buckyball." Ama-athomu e-carbon angamashumi ayisithupha ahlangana ndawonye ukuze akhe ikheji elivaliwe. Iphethini ihlanganisa ama-pentagon ayi-12 nama-hexagon angama-20. I-athomu ngayinye ye-carbon ibophana nomakhelwane abathathu. Ezimbili zalezi zibopho ziyizibopho ezilodwa nama-pentagon, kanti enye iyisibopho esiphindwe kabili ne-hexagon. Ama-engeli esibopho alinganisa cishe ama-120° nama-108°, okwenza isakhiwo sihluke ku-graphite noma idayimane.
Ungaqhathanisa i-Fullerene C60 nezinye izinhlobo zekhabhoni ngokubheka izakhiwo zazo:
| I-Carbon Allotrope | Incazelo Yesakhiwo |
|---|---|
| I-Fullerene C60 | Isakhiwo sekheji elivaliwe elinama-pentagon ayi-12 nama-hexagon angama-20, okubonisa ukulingana okuphezulu. |
