Fullerenes tuaj yeem yog siv rau kev xa tshuaj rau hauv lub cev, raws li lubricants, thiab raws li catalysts. Lawv tuaj yeem ua raws li qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Nov yog qhov lawv nqa tau tshuaj molecules nyob ib ncig ntawm lub cev thiab xa lawv mus rau qhov chaw uas lawv xav tau, thiab ntxiab cov khoom txaus ntshai hauv lub cev thiab tshem tawm lawv.
Ua raws li qhov xav tau, cov fullerenes siv hauv catalysts li cas?
Nanotubes ua raws li catalysts thaum muaj hluav taws xob tam sim no dhau los ntawm lawv. Qhov no ua rau lawv pub dawb electrons rau cov molecules uas tuaj rau hauv kev sib cuag nrog cov chaw tshuaj tiv thaiv. Hmoov zoo, lwm cov tshuaj tiv thaiv uas carbon nanotubes tuaj yeem hloov pauv cov tshuaj hu ua resazurin mus rau lwm qhov, resorufin, uas yog fluorescent.
Ib sab saum toj no, fullerenes ua haujlwm li cas? A fullerene yog ib qho allotrope ntawm cov pa roj carbon uas nws cov molecule muaj cov pa roj carbon atoms txuas los ntawm ib leeg thiab ob daim ntawv cog lus thiaj li rau tsim ib qho kaw lossis ib nrab kaw mesh, nrog fused rings ntawm tsib rau xya atom. Cov molecule tej zaum yuav yog ib tug hollow kheej kheej, ellipsoid, raj, los yog ntau lwm yam duab thiab ntau thiab tsawg.
Tib neeg kuj nug, vim li cas cov fullerenes siv los ua roj nplua nyeem?
Buckyballs yog qhov zoo lubricants vim lawv cov duab kheej kheej. Lawv cov qauv hollow tuaj yeem ua rau lawv muaj txiaj ntsig zoo rau kev xa tshuaj yav tom ntej. Cov pa roj carbon nanotubes muaj zog heev thiab lub teeb, thiab tuaj yeem ua cov semiconductors lossis conductors. Lawv yog siv ntxiv dag zog rau cov khoom sib xyaw.
Dab tsi yog qhov zoo ntawm kev siv fullerenes?
Raws li cov kws tshawb fawb taw qhia, kev siv polyhydroxy fullerenes rau mob qog noj ntshav theranostics muaj ntau yam zoo dua tam sim no tau npaj ib phab ntsa carbon nanotubes thiab kub raws li nanostructures: PHF yog dej-soluble, biocompatible thiab biodegradable, thiab tau pom tias muaj antioxidant zog, inhibit.

Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Yuav siv cov tshuaj neutralization li cas los nrhiav cov concentration ntawm cov kua qaub?
Ib qho titration yog ib qho kev sim uas siv cov tshuaj tiv thaiv acid-base neutralization los txiav txim qhov tsis paub txog cov kua qaub lossis lub hauv paus. Qhov sib npaug taw tes yog mus txog thaum tus naj npawb ntawm hydrogen ions sib npaug rau tus naj npawb ntawm hydroxide ions
Yog vim li cas sodium poov tshuaj twj tso kua mis suav hais tias yog ib qho kev thauj mus los uas cov kev taw qhia yog cov sodium thiab poov tshuaj tau pumped?
Sodium-Potassium Pump. Kev thauj mus los yog lub zog xav tau cov txheej txheem ntawm kev siv cov molecules thiab ions hla daim nyias nyias 'nce toj' - tiv thaiv kev sib tw gradient. Txhawm rau txav cov molecules tawm tsam lawv cov concentration gradient, yuav tsum muaj cov khoom siv protein
Cov tshuaj tiv thaiv zoo li cas thaum cov tshuaj nkag mus rau hauv cov hlab ntsha?
Cov tshuaj tiv thaiv 'systemic' tshwm sim thaum cov tshuaj nkag mus rau hauv cov hlab ntsha los ntawm daim tawv nqaij, qhov muag, qhov ncauj, lossis lub ntsws
Vim li cas CDCl3 yog siv los ua cov kuab tshuaj rau sau cov NMR spectrum ntawm ib qho kev sib txuas?
Nws tuaj yeem tau yooj yim sib cais los ntawm kev sib xyaw tom qab dissolving vim tias nws yog volatile nyob rau hauv cov xwm, thiaj li yuav yooj yim evaporated. Vim muaj cov tsis-hydrogen atom nws tsis cuam tshuam rau kev txiav txim siab ntawm NMR spectrum. Raws li nws yog cov kuab tshuaj deuterated yog li nws lub ncov tuaj yeem txheeb xyuas tau yooj yim hauv NMR nrog kev siv ntsuas TMS
