Nano-Heating Wonders: 2-5nm Tubes rau cov kev daws teeb meem tshiab

Nrog nws cov khoom tshwj xeeb nano-kub cua sov, 2 - 5 nm hlab tau dhau los ua qhov kev loj hlob zoo nyob rau hauv kev hloov pauv sai ntawm nanotechnology, npaj los hloov ntau yam sib txawv.
Feem ntau ua los ntawm cov ntaub ntawv uas nthuav tawm cov yam ntxwv zoo nkauj nanoscale, cov nanotubes no muaj cov kab me me hauv 2-5 nm. Ib qho piv txwv zoo tiag tiag yog carbon nanotubes. Ua los ntawm dov-up graphene nplooj ntawv, lawv qhia txawv txawv mechanical zog thiab hluav taws xob conductivity. Quantum - mechanical phenomena ua haujlwm ntawm qhov ntsuas me me, muab cov nanotubes tshwj xeeb lub cev thiab tshuaj lom neeg yam tsis muaj nyob hauv lawv cov khoom sib npaug.
Lub tshuab hluav taws xob semiconductor yog ib qho ntawm cov haujlwm zoo siab tshaj plaws ntawm kev siv rau cov raj 2-5 nm. Kev koom ua ke ntawm cov nanotubes no muab txoj hauv kev ua ntej raws li lub siab xav kom me me, nrawm dua, ntau lub zog siv hluav taws xob ua kom muaj zog ntxiv. Cov khoom siv semiconductor tso cai rau ib qho los tsim ultra-luv channel ntev transistors rau cov khoom siv semiconductor. Qhov no cia transistors tig nrog ntau lub zog siv qis dua thiab nrawm dua. Rau huab - ultraviolet (EUV) lithography, piv txwv li, kev tswj xyuas meej ntawm cov yam ntxwv ntawm 2 - 5 nm cov hlab ntsha tuaj yeem ua rau qhov xav tau kev daws teeb meem los tsim sub - 10 nm loj transistors. Cov txheej txheem lithography tuaj yeem txhim kho los ntawm kev kho kom zoo ntawm cov khoom siv hluav taws xob thiab thermal ntawm cov nanotubes, yog li tsim cov khoom ntim tau zoo, ua tau zoo heev.
Cov raj nano cua sov no kuj tseem yuav muaj txiaj ntsig zoo rau kev kho mob. Ntawm cov kev siv nthuav tshaj plaws yog tsom rau kev xa tshuaj. Ib tus tuaj yeem ua haujlwm rau cov nanotubes no txhawm rau tsom cov qog nqaij hlav cancer tshwj xeeb. Cov tshuaj tuaj yeem muab tso rau hauv nanotubes tom qab lawv tau txuas mus rau cov qog nqaij hlav cancer. Los ntawm kev siv cov stimuli sab nraud, zoo li lub teeb ze-infrared, cov nanotubes sov thiab ua rau cov tshuaj tso tawm. Qhov no tsom rau cov cua sov thiab cov tshuaj tso tawm tsis yog tsuas yog ua kom muaj txiaj ntsig kho mob qog noj ntshav xwb tab sis kuj txo qis cov txiaj ntsig tsis zoo rau cov hlwb noj qab haus huv. Tsis tas li ntawd, qhov tshwj xeeb kho qhov muag thiab hluav taws xob cov yam ntxwv ntawm 2-5 nm raj yuav siv tau rau hauv cov ntawv siv bio-sense los txheeb xyuas biomarkers txuas nrog cov kab mob ntawm qhov qis heev. Los ntawm kev tso cai rau kev kho mob sai, muaj peev xwm tshawb pom ntxov ua rau cov neeg mob tau txais txiaj ntsig zoo.
Ob mus rau tsib nanometer raj muaj peev xwm loj heev nyob rau hauv lub tshav pob ntawm lub zog cia. Piv txwv li, cov nanotubes no tuaj yeem txhim kho kev ua haujlwm ntawm lithium-ion roj teeb hauv ntau yam. Kev them nyiaj sai dua thiab kev tso tawm tau ua tau los ntawm lawv txoj kev txhim kho ntawm electrode conductivity. Thaum tshav kub kub yog tsim thiab cov nanotubes tuaj yeem tswj tau zoo thoob plaws hauv lub voj voog them nqi. Kev siv hluav taws xob zoo ua kom tsis txhob muaj roj teeb overheating, yog li ncua nws lub neej thiab txhim kho nws txoj kev nyab xeeb. Ntau lub zog cia muaj peev xwm ua tau los ntawm cov nanotubes kuj ua rau thaj chaw saum npoo nkag tau rau cov txheej txheem electrochemical.
Kev siv lub zog ntawm 2-5 nm raj rau cov kev siv qib siab no nthuav tawm qee cov haujlwm nyuaj, txawm li cas los xij. Cov txheej txheem tsim khoom yog qhov nyuaj heev thiab hu rau lub xeev-ntawm -- cov cuab yeej kos duab. Technically nyuaj yog loj hlob carbon nanotubes nrog xws li qhov ntau thiab tsawg. Tus cwj pwm tshwj xeeb ntawm cov txheej txheem yuav tsum tau ua thiab qhov xav tau ntawm kev huv - chav tsev ib puag ncig ua rau cov nqi tsim khoom lag luam shockingly kim. Tsis tas li ntawd muab cov raj nanoscale rau hauv cov tshuab tam sim no hu rau cov qauv tsim tshiab. Lwm yam teeb meem kev sib raug zoo ntawm cov khoom siv yuav tsim; nanotube cwj pwm ntawm nanoscale tej zaum yuav nyuaj rau kev kwv yees thiab tswj.
Txawm hais tias cov kev cov nyom no, siv 2-5 nm raj yuav muab cov txiaj ntsig tseem ceeb. Cov tuam txhab thev naus laus zis nrhiav kev tsim kho tshiab thiab kev vam meej yuav pom muaj txiaj ntsig zoo hauv lawv qhov tseeb thiab kev tswj hwm hauv cheeb tsam ntawm nanoscale. Peb yuav cia siab tias cov raj nanoscale no yuav dhau los ua ib qho tseem ceeb ntawm cov kev xav tau yav tom ntej raws li kev tshawb fawb thiab kev tsim kho kev ua haujlwm nrawm txhawm rau txhim kho cov txheej txheem tsim khoom thiab kev sib koom ua ke, yog li tso cai rau cov ntawv thov yav dhau los xav tias ua tsis tau.
2-5 nm raj cim qhov zoo tshaj plaws thiab kev hloov pauv thev naus laus zis. Lawv lub peev xwm loj los hloov lub zog cia, kho tshuaj kho mob, thiab kev tsim khoom semiconductor Txawm hais tias lawv cov khoom tsim thiab kev sib koom ua ke tam sim no muaj teeb meem loj, kev tshawb fawb thiab kev tsim kho txuas ntxiv yuav pab kom kov yeej cov teeb meem no thiab qhib txoj hauv kev rau lub hnub nyoog tshiab ntawm kev tsim kho thev naus laus zis ua tau los ntawm cov nanoscale. txuj ci tseem ceeb.
