Ib pab neeg ntawm physicists los ntawm Australian National University (ANU) thiab University of Adelaide tau tshaj tawm tias los ntawmtsim lub teeb tshiab siv nanoparticles, lawv yuav tuaj yeem soj ntsuam lub ntiaj teb ntawm cov khoom me me ntau txhiab zaus me dua li tib neeg cov plaub hau, Qhov no tau cog lus tias yuav ua rau muaj kev txhim kho loj hauv tshuaj thiab lwm yam thev naus laus zis.
Cov kev tshawb fawb tuaj yeem muaj kev cuam tshuam loj rau kev tshawb fawb txog kev kho mob vim nws muab cov txiaj ntsig zoo rau kev tshuaj xyuas cov khoom me me uas yav tas los tsis tuaj yeem "pom" nrog lub tshuab tsom, thiab kev ua haujlwm kuj tseem tuaj yeem muaj txiaj ntsig zoo rau kev lag luam semiconductor los ntawm kev txhim kho kev tswj hwm ntawm lub computer nti. kev tsim khoom.
ANU thev naus laus zis siv ua tib zoo tsim cov nanoparticles kom nce qhov zaus ntawm lub teeb pom los ntawm cov koob yees duab thiab lwm yam thev naus laus zis los ntawm ib qho ntawm xya. Muaj "tsis muaj kev txwv" mus deb npaum li cas ntawm lub teeb tuaj yeem txhawb nqa, cov kws tshawb fawb tau hais. Qhov ntau zaus, cov khoom me me uas peb pom nrog lub teeb ci.
Cov thev naus laus zis, uas tsuas yog xav tau ib qho nanoparticle nkaus xwb los ua haujlwm, tuaj yeem siv rau lub tshuab tsom iav, pab cov kws tshawb fawb zoom nyob rau hauv lub ntiaj teb ntawm cov khoom me me ntawm 10 npaug ntawm qhov kev daws teeb meem ntawm cov khoom siv microscopes. Qhov no yuav tso cai rau cov kws tshawb fawb los kawm txog cov khoom uas tsis yog qhov tsawg dhau los pom, xws li cov qauv sab hauv ntawm cov hlwb thiab cov kab mob ntawm tus kheej. Muaj peev xwm txheeb xyuas cov khoom me me zoo li no tuaj yeem pab cov kws tshawb fawb kom nkag siab zoo dua thiab tawm tsam qee yam kab mob thiab kev noj qab haus huv.
"Tseem niaj hnub microscopes tsuas tuaj yeem kawm cov khoom loj dua li ib kaum-millionth ntawm ib lub 'meter'. Txawm li cas los xij, muaj kev xav tau ntau ntxiv hauv ntau thaj chaw, suav nrog kev kho mob, kom muaj peev xwm txheeb xyuas cov khoom me me li ib billionth ntawm ib lub 'meter'. ," hais tias tus kws sau ntawv los ntawm "Peb cov thev naus laus zis tuaj yeem pab ua kom tau raws li qhov xav tau no," tus thawj coj kws sau ntawv Dr. Anastasiia Zalogina, los ntawm Australian National University's Research School of Physics thiab University of Adelaide.
Nanotechnology tsim los ntawm Australian National University tuaj yeem pab tsim lub cim tshiab ntawm microscopes uas tuaj yeem tsim cov duab ntxaws ntxiv, cov kws tshawb fawb hais.
"Cov kws tshawb fawb uas xav tsim cov duab loj heev ntawm cov khoom me me nanoscale tsis tuaj yeem siv lub teeb pom kev zoo li qub. Xwb, lawv yuav tsum tau tso siab rau super-resolution microscopy lossis siv electron microscopy los kawm cov khoom me me no," said Dr. Zalogina "Tab sis cov txheej txheem no. qeeb thiab kim heev, feem ntau raug nqi ntau dua $ 1 lab. Lwm qhov tsis zoo ntawm electron microscopy yog tias nws tuaj yeem ua rau cov qauv me me uas raug tshuaj xyuas, uas yog txo los ntawm lub teeb microscopy. " ."
Thaum peb ob lub qhov muag tsis tuaj yeem ntes lub teeb infrared thiab ultraviolet, nws muaj peev xwm rau peb "pom" lawv los ntawm lub koob yees duab thiab lwm yam thev naus laus zis. Co-sau Dr. Sergey Kruk, kuj yog los ntawm Australian National University, hais tias cov kws tshawb fawb tau txaus siab rau kev nkag mus rau lub teeb hluav taws xob ntau zaus, los yog hu ua ' ultraviolet heev'. Peb tuaj yeem pom tej yam me me nrog lub teeb violet dua li lub teeb liab. Thiab nrog lub teeb pom kev zoo ntawm ultraviolet, peb tuaj yeem pom ntau dua li qhov ua tau nrog cov tshuab tsom iav niaj hnub no.
Dr. Sergey Kruk tau hais tias ANU thev naus laus zis kuj tseem tuaj yeem siv rau hauv kev lag luam semiconductor raws li kev tswj xyuas kom zoo los xyuas kom meej cov txheej txheem tsim khoom. "Computer chips yog tsim los ntawm cov khoom me me, nrog cov yam ntxwv ntsuas yuav luag ib txhiab lab ntawm ib lub 'meter'. Thaum lub sijhawm tsim cov chips, nws yog ib qho tseem ceeb rau cov tuam txhab siv me me heev ultraviolet lub teeb los saib xyuas cov txheej txheem hauv lub sijhawm tiag tiag rau kev kuaj mob ntxov. cov lus nug, nws yuav pab tau. "
Nyob rau hauv txoj kev no, cov tuam ntxhab tuaj yeem txuag cov peev txheej thiab lub sijhawm ntawm kev ua cov chips tsis zoo, yog li ua kom cov qoob loo ntawm chip manufacturing. Nws tau kwv yees tias txhua 1 feem pua nce hauv cov khoom siv hluav taws xob hauv computer txuag $ 2 billion.
"Australia txoj kev vam meej ntawm optics thiab optoelectronics kev lag luam, sawv cev los ntawm ze li ntawm 500 tuam txhab uas muag thiab nrog kev lag luam ntawm kwv yees li $ 4.3 billion, ua haujlwm rau peb cov txheej txheem thev naus laus zis los txhawb cov teeb pom kev tshiab thiab nkag mus rau thaj chaw tshiab ntawm nanotechnology kev lag luam thiab kev tshawb fawb thoob ntiaj teb," said Dr. Sergey Kruk.
Txoj haujlwm tau ua los ntawm pab pawg tau hais los saum no hauv kev koom tes nrog cov kws tshawb fawb los ntawm University of Brescia, Arizona, thiab Kaus Lim Kauslim.
