Qhia: thev naus laus zis ntawm microscopes
Hauv keeb kwm ntawm kev txhim kho niaj hnub, cov xov xwm tshawb nrhiav tau sai heev nrog kev txhim kho ntawm cov tshuab hluav taws xob me me ntawm cov tshuab hluav taws xob tshiab. Atomic quab yuam metcopy tuaj yeem siv rau hauv ntau qhov chaw tshawb fawb, xws li cov khoom siv hluav taws xob, thiab lwm yam rau cov chaw tshawb fawb thiab lub tswv yim.
Raws li cov lus tshaj tawm, Cornlell University Doricist KanoelectRonics uas tuaj yeem ntes cov duab ntawm tus kheej ntawm qhov chaw ceev tsawg kawg 100 npaug ntawm cov khoom siv hluav taws xob uas twb muaj lawm. Kev ntsuas lub tsom iav siv tau siv lub peev xwm ntawm quarum the totneling los ntawm kev ntsuas kom ntsuas qhov kev ncua deb ntawm rab koob ntes thiab ua kom zoo.
Cov kws tshawb nrhiav ntxiv xov tooj cua ntau zaus hauv qhov chaw thiab xa ib nthwv dej mus rau hauv lub tshuab ntsuas hluav taws xob los ntawm lub network yooj yim. Lawv pom tias lawv tuaj yeem siv tus yam ntxwv ntawm kev cuam tshuam ntawm nthwv dej ntawm cov hauv paus kom pom cov kev tawm tsam ntawm lub qhov kev sib tua. Qhov kev thev naus laus zis no yog hu ua kev xav txog cov kev xav, uas siv cov qauv txheem tsim kho kom zoo thiab tsis qeeb vim kev muaj peev xwm muaj peev xwm muaj peev xwm txwv. Thiab ib qho voltage me me tau thov rau cov qauv, txav lub ntsuas mus rau ib txoj haujlwm tsuas yog ob peb lub angstroms saum npoo ntawm cov qauv.
Nws yuav tsum tau sau tseg tias kev ntsuas lub xov tooj ntawm lub tshuab tsom me me tuaj yeem khaws cov tshuab hluav taws xob nrawm nrawm nrawm nrawm nrawm nrawm ntawm ib lub voj voog lab ib pliag. Txawm li cas los xij, ib qho scanning nplai lub micrneling yog txwv los ntawm lub peev xwm ntawm kev nyeem hluav taws xob cable lossis lub zog cia, thiab nws qeeb, li tsawg dua.
Nws yog tsim nyog teev tias cov kws tshaj lij qhia tias cov thev naus laus zis no tseem muaj peev xwm tsim cov ntsuas qib Atomic. Lawv ntseeg khov ntseeg tias nyob rau hauv 10 xyoo, yuav muaj ntau ntawm RF scanning scanning pawm uas tib neeg tuaj yeem siv rau ntau yam kev sim muaj txiaj ntsig zoo. Qhov tsim muaj ntawm atomic yuam microscopy tau muab lub zej zog scientific uas tsis muaj kev pom zoo, ua kom pom cov atoms thiab lwg me me ntawm cov khoom siv cov khoom tsis yog npau suav.
