Key Takeaways
- Cov khoom siv tshiab, tawv tawv tuaj yeem hloov lub laptops thiab lwm yam khoom siv hluav taws xob ntawm tus kheej.
- Cov khoom hu ua 2DPA-1 muaj zog heev nws tseem tuaj yeem txhawb nqa lub tsev.
- Lwm cov ntaub ntawv tshiab tuaj yeem tsim cov sensors uas ua rau peb lub xov tooj paub ntau ntxiv txog peb ib puag ncig.
Laptops thiab lwm yam khoom siv yuav sai sai dua thiab muaj zog dua.
MIT cov kws tshawb fawb tau tsim cov khoom siv tshiab li lub teeb li yas thiab muaj zog li hlau. Cov khoom siv, hu ua 2DPA-1, yog hom polyaramide uas tuaj yeem tsim los ntawm kev lag luam. Nws yog qhov tseeb nyob rau hauv nthwv dej ntawm cov ntaub ntawv tshiab uas tuaj yeem hloov kho tus kheej hluav taws xob.
"Muaj ntau yam teeb meem tau daws los ntawm cov ntaub ntawv tshiab," Terry Gilton, tus kws tshaj lij cov ntaub ntawv uas yog tus khub ntawm lub tuam txhab lag luam thev naus laus zis Celesta Capital, hais rau Lifewire hauv kev sib tham hauv email. "Xav txog qhov pom me me kom haum rau ob lub looj tsom iav dub uas yuav tuaj yeem qhia koj txhua yam koj tuaj yeem pom tam sim no ntawm koj lub xov tooj zaub."
Self-Assembly
MIT cov khoom tshiab yog ob-seem polymer uas nws tus kheej sib sau ua ke rau hauv cov ntawv, tsis zoo li tag nrho lwm cov polymers, uas tsim ib-dimensional, spaghetti-zoo li chains. Cov kws tshawb fawb ntseeg tias nws tsis tuaj yeem ntxias cov polymers los ua 2D nplooj ntawv txog tam sim no.
Cov khoom siv zoo li no tuaj yeem siv los ua lub teeb yuag, siv tau ntev rau lub tsheb qhov chaw lossis lub xov tooj ntawm tes, lossis ua cov khoom siv hauv tsev rau cov choj lossis lwm cov qauv, Michael Strano, tus xibfwb ntawm chemical engineering ntawm MIT thiab tus kws sau ntawv laus ntawm txoj kev kawm tshiab.

"Peb feem ntau tsis xav txog cov yas ua ib yam dab tsi uas koj tuaj yeem siv los txhawb lub tsev, tab sis nrog cov khoom siv no, koj tuaj yeem ua tau yam tshiab," nws hais hauv xov xwm tshaj tawm.
Cov kws tshawb nrhiav pom tias cov khoom siv tshiab elastic modulus-ib qho kev ntsuas ntawm lub zog nws siv ntau npaum li cas los ua kom cov khoom deform-yog li ntawm plaub mus rau rau lub sijhawm ntau dua li cov iav tsis muaj phom. Lawv kuj pom tias nws lub zog tawm los, lossis ntau npaum li cas nws yuav siv los rhuav tshem cov khoom, yog ob npaug ntawm cov hlau, txawm tias cov khoom siv tsuas yog ib feem ntawm qhov ntom ntawm cov hlau.
Hauv kev tshaj tawm xov xwm, Matthew Tirrell, tus thawj coj ntawm Pritzker Tsev Kawm Ntawv ntawm Molecular Engineering ntawm University of Chicago, uas tsis koom nrog hauv txoj kev tshawb no, hais tias cov txheej txheem tshiab "embodies ib co tswv yim zoo heev chemistry los ua cov kev sib raug zoo 2D. polymers."
Lwm qhov tseem ceeb ntawm 2DPA-1 yog tias nws tsis tuaj yeem nkag mus rau cov pa roj. Thaum lwm cov polymers yog tsim los ntawm coiled chains nrog qhov khoob uas tso cai rau gasses kom nkag mus, cov khoom tshiab yog tsim los ntawm cov monomers uas kaw ua ke zoo li LEGOs, thiab cov molecules tsis tuaj yeem nruab nrab ntawm lawv.
"Qhov no tuaj yeem tso cai rau peb los tsim cov txheej txheem ultrathin uas tuaj yeem tiv thaiv dej lossis gasses los ntawm kev nkag mus," Strano hais. "Cov txheej txheem no tuaj yeem siv los tiv thaiv hlau hauv tsheb thiab lwm lub tsheb, lossis cov qauv hlau."
"Peb tsis tshua xav txog cov yas ua ib yam dab tsi uas koj tuaj yeem siv los txhawb lub tsev…"
Cov Khoom Tshiab
Qhov kev tshawb pom MIT tsuas yog ib qho ntawm ntau cov ntaub ntawv uas yuav muaj sai sai no los txhim kho gadgets. Piv txwv li, tshiab nanoparticle versions ntawm ntau yam hlau zoo li titanium yuav ua rau 3D luam ntawv ntawm hlau Cheebtsam sai thiab pheej yig dua, Gilton hais. Qhov no 'additive manufacturing' siv hlau yog revolutionizing manufacturing.
Cov thev naus laus zis tshiab zoo li quantum dots tuaj yeem hloov cov ntaub ntawv tam sim no uas siv rau cov saib thiab cov ntxaij vab tshaus, Gilton tau taw qhia. "Lawv zoo dua ntawm kev lim lub teeb thiab pom cov xim zoo dua raws li cov khoom sib txuas tshiab," nws hais ntxiv.
Lwm cov ntaub ntawv tshiab tuaj yeem tsim cov sensors uas ua rau peb lub xov tooj paub ntau ntxiv txog peb ib puag ncig ib puag ncig, Gilton tau hais. Piv txwv li, cov polymers tshwj xeeb uas hloov pauv thaum lawv nqus qee cov pa roj tso cai rau kev tsim cov khoom siv hluav taws xob 'qhov ntswg' ntawm lub nti.
Cov tuam txhab tab tom tshawb nrhiav cov tswv yim tshiab rau cov khoom siv hauv tsev uas yuav ua rau cov chips tsim nrog atomic precision, Casper van Oosten, tus thawj coj thiab tus thawj coj ntawm kev lag luam teb rau Intermolecular, kev lag luam ntawm Merck KGaA, Darmstadt, Lub teb chaws Yelemees, hais Lifewire ntawm email. Cov ntaub ntawv yog tsim atom-by-atom kom muaj peev xwm ua kom pheej yig dua, sai dua, thiab ntau zog-npaum lub computer chips.
"Cov neeg siv khoom yuav pom qhov no rov qab los ntawm kev tawg ntawm 'ntse' lossis 'ntse' cov khoom siv nyob ib puag ncig peb, los ntawm kev tsav tsheb tus kheej mus rau AR / VR tsom iav hloov peb lub Zoom hu tsis tu ncua, "nws hais.
