Nyob rau hauv xyoo tas los no, nrog kev nce hauv streaming,fullerene hmoov, uas yog ib tug paub tsis meej txij thaum yug los, tau maj mam nkag mus rau hauv lub qhov muag ntawm pej xeem, thiab los ntawm lub touting ntawm ntau lub tuam txhab thiab kev zoo nkauj bloggers, fullerene tau hailed raws li "tus huab tais ntawm antioxidants". Nws tau tshaj tawm tias muaj ze li ntawm 10, 000 cov ntaub ntawv tshawb fawb thiab 3, 000 patents ntawm cov txiaj ntsig kho tawv nqaij ntawm fullerene. Los ntawm kev tshawb fawb mus rau kev siv tswv yim, fullerene tau nyob rau hauv lub tsom teeb ntawm kev zoo nkauj kev lag luam txij li thaum lawv nrhiav tau cov kev pab cuam ntawm daim tawv nqaij, thiab tau los ua ib tug nrhiav-tom qab muaj nyob rau hauv lub cosmetic kev lag luam.
Lub hnub yug ntawm fullerene pib nrog kev tshawb fawb astronomical. Cov kws tshawb fawb tau paub ntev ntev tias carbon yog lub ntsiab lus tseem ceeb uas tsim lub neej hauv ntiaj teb. Thiab nyob rau xyoo 1970, Harold Kroto thiab lwm tus tau teeb tsa kev tshawb nrhiav lub neej extraterrestrial thaum lawv nrhiav pom, los ntawm kev soj ntsuam hauv xov tooj cua astronomy, muaj coob tus ntawm cov saw ntev carbon molecules nyob rau hauv interstellar qhov chaw. Kroto ntseeg hais tias cov saw hlau ntev ntev tsis zoo no tau tsim nyob rau hauv cov huab cua ntawm carbon-nplua nuj liab giants.
Txhawm rau ntsuas qhov kev xav no, nws yuav tsim nyog los ua cov kev sim uas simulated ib puag ncig stellar, thiab hauv 1984, thaum mus koom lub rooj sib tham molecular hauv Texas, Kroto ntsib ib tug phooj ywg qub, Robert Curl. Thaum lub sijhawm sib tham, Kroto tau kawm tias Cole tam sim no tau ua haujlwm ntawm cov khoom siv semiconductor hauv kev koom tes nrog nws cov npoj yaig Smalley ntawm Rice University. Thiab nws paub tias Richard Smalley muaj lub tshuab super, Cluster Beam Generator (aka AP2), uas tuaj yeem siv los soj ntsuam cov qauv kab txawv.
Kroto tau txaus siab los ntawm cov cuab yeej thiab ua raws Cole mus rau Rice University tom qab lub rooj sib tham. Tom qab pom AP2 ntawm tus kheej, nws tam sim ntawd pom tau hais tias nws tuaj yeem siv los ntsuas nws txoj kev xav ntawm kev tsim cov pa roj carbon molecules thiab tau thov kom peb tus txiv neej koom tes hauv txoj kev tshawb no.
Tom qab ib lub sijhawm ntawm kev sim, lawv pom ob qhov txiaj ntsig tseem ceeb: qhov kev npaj txhij txog ntev-chain carbon molecule uas Smalley hu ua "Kroto's long carbon nab" thiab yav tas los tsis paub tseeb cov pa roj carbon monoxide. Kev tsom xam spectrometer tau pom tias feem ntau ntawm cov pa roj carbon molecules muaj 60 carbon atoms, thiab qee qhov muaj 70 carbon atoms.
Kroto zoo siab nrog cov khoom uas tsis tau xav txog. Cov kev tshawb fawb ntxiv tau qhia tias C60 ruaj khov heev, qhia tias cov molecule tej zaum yuav muaj cov qauv zoo sib xws uas tsis muaj cov pa roj carbon monoxide dawb lossis cov nyiaj tsis muaj txiaj ntsig valence. Tom qab qee qhov kev xav nyuaj, pab pawg tau tuaj nrog tus qauv "pob ncaws pob": tag nrho cov molecule muaj pentagons thiab hexagons stitched ua ke los tsim ib lub tawb zoo li cov qauv. Lub tswv yim tau txais kev tshoov siab los ntawm kev ua haujlwm ntawm tus kws kes duab vajtse Buckminster Fuller - US Pavilion ntawm Montreal World's Fair, nrog nws cov phiaj xwm loj zoo li dome. Pab pawg hu ua cov pa roj carbon molecules buckminsterfullerene (tom qab hloov mus rau fullerene).
Rau daim ntawv thov ntawm fullerene, lub ntsiab daim ntawv thov kev taw qhia nyob rau hauv lub tebchaws United States yog fullerene lubricant additives, thiab cov teb chaws Europe feem ntau txhawb nqa fullerene composite cov ntaub ntawv. Nyob rau hauv lub teb ntawm cov tshuaj pleev ib ce, European thiab American hom muaj tsawg daim ntawv thov rau fullerene, ntau los yog lub teb chaws thiab Japanese hom, uas cov thawj mus thov fullerene nyob rau hauv kev zoo nkauj yog Nyiv lub Mitsubishi.
Txawm hais tias Tuam Tshoj kuj tseem lig rau daim ntawv thov ntawm fullerene, tab sis nyob rau hauv kev tshawb fawb thiab kev xyaum tsis tu ncua, tau ua tiav ntau yam kev siv ntawm fullerene nyob rau hauv ib tug xov tooj ntawm cov teb, ib tug ntawm cov feem ntau lug siv nyob rau hauv lub teb ntawm tshuaj pleev ib ce.
Fullerene muaj qhov ruaj khov peb-dimensional non-deterministic conjugated molecular qauv, uas tuaj yeem tiv thaiv cov dawb radicals. Cov huab cua-nplua nuj electron ntawm fullerene deactivates lub unpaired radicals, thiab lub fullerene tsis hnov mob nrog cov radicals nyob rau hauv cov txheej txheem no, tab sis tsuas yog plays lub luag hauj lwm ntawm electron thauj, yog li nws muaj peev xwm ua hauj lwm stably rau lub sij hawm ntev. Fullerene muaj peb yam tseem ceeb: quenching dawb radicals, ntev-ntev antioxidant, inhibiting inflammatory yam, regulating inflammatory teb, kho thiab tiv thaiv cellular kev ua si. Molecular biology kev tshawb fawb tau pom tias fullerenes tswj cellular metabolic homeostasis los ntawm kev tswj intracellular mitochondrial respiratory chain complex enzymes thiab li no kho mitochondrial puas. Fullerene cov qauv molecular ruaj khov thiab muaj txiaj ntsig zoo ntawm cov dawb radicals ua rau nws muaj peev xwm rau ntau yam kev siv tshuaj biomedical, piv txwv li, ua tshuaj rau kev kho mob loj xws li mob qog noj ntshav, ntshav qab zib, thiab Parkinson's, lossis ua tus neeg sawv cev sib txawv rau MRI. rau kev kuaj mob kuaj mob.
Tsis tas li ntawd, fullerenes tiv thaiv hom I / IV collagen fibers, feem ntau los ntawm inhibiting kev puas tsuaj ntawm hom I / IV collagen fibers. Catalase thiab glutathione nyob rau hauv daim tawv nqaij yog inhibited los ntawm UV teeb thiab dawb radicals, thaum C60 tsis cuam tshuam, yog li supplementing lub physiological antioxidant kev ua ntawm daim tawv nqaij. Fullerene kuj synergizes nrog VC nyob rau hauv daim tawv nqaij kom tswj ib txwm collagen synthesis, feem ntau yog los ntawm kev tiv thaiv VC los ntawm reactive oxygen hom, ua kom VC nquag, tswj cov kev ua ntawm collagen synthase, thiab txhawb collagen synthesis. Fullerene muaj tag nrho ntawm xya qhov txiaj ntsig ntawm kev saib xyuas tawv nqaij, suav nrog kev tiv thaiv kev laus thiab kev tshem tawm wrinkle, ntxuav hniav dawb thiab txo qis, tawv nqaij zawm thiab rov ua dua tshiab, cov plaub hau dawb rau cov xim dub, tiv thaiv plaub hau poob thiab ntom ntom, tiv thaiv kab mob thiab pob txuv, thiab tiv thaiv. kev tsis haum tshuaj kho. Cov kws tshawb fawb tau siv cov tshuaj potassium iodide oxidation discoloration test los kuaj thiab sib piv cov antioxidant muaj peev xwm ntawm fullerene thiab VC. Cov txiaj ntsig tau pom tias lub zog antioxidant ntawm fullerene yog ntau dua 1000 npaug ntawm VC.
Tsis tas li ntawd, piv rau lwm cov khoom xyaw ntawm kev tu tawv nqaij, qhov nyuaj ntawm kev siv cov hmoov fullerene nyob rau hauv lawv cov khoom nyuaj thiab cov txiaj ntsig me me, vim tias fullerene tsis muaj nyob hauv lub ntiaj teb thiab tsis tuaj yeem tau txais ib txwm muaj, yog li lawv yuav tsum vam khom cov thev naus laus zis kom tau txais. lawv. Ib xyoo caum dhau los, fullerene siv los ua ib qho ntawm cov khoom xyaw uas kim tshaj plaws. Yog li, nws tau raug hu ua "pob zeb diamond khoom ntawm kev lag luam kev zoo nkauj". Txawm li cas los xij, ua tsaug rau kev siv zog ntawm cov kws tshawb fawb hauv tsev thiab txawv teb chaws, thev naus laus zis ntawm kev npaj ntau ntawm high-purity fullerene hmoov tau kov yeej, thiab cov nqi ntawm cov ntaub ntawv fullerene tau poob qis, ua rau nws muaj peev xwm ua kom zoo nkauj.
