Ib pab kws tshawb fawb los ntawm University of Exeter siv nanotechnology los sib xyaw nrog graphene ua vaj tse. Txhawm rau ua qhov no, lawv tau ntxiv kev ncua ntawm graphene hais thiab ib qho tshuaj tiv thaiv kom haum rau hauv lub tsev sib xyaw, uas tiv thaiv cov graphene los ntawm clumping. Cov kev sim ua rau cov khoom siv sib xyaw ua ke uas muaj zog tshaj ob zaug thiab muaj plaub zaug tiv taus ya raws dua li cov pa pob zeb.
Tib lub sijhawm, cov pob zeb ua tau tshiab tseem muaj kev lag luam ntau dua: kom tau nws, cov kws tshawb nrhiav yuav tsum tau 50% tsawg dua qhov sib xyaw ua ke thaum piv nrog cov kev ua ib txwm muaj. "Qhov no, ua rau txo qis 446 kg hauv kev txo cov pa roj carbon dioxide tawm hauv cov tuj ntawm cov khoom," piav qhia cov kws tshawb fawb pab pawg thawj coj ntawm Monica Craciun. Raws li cov tswvcuab pab pawg Dimitar Dimov, pob zeb-ua kom muaj zog ntxiv, nrog nws txoj haujlwm dav thiab cov txiaj ntsig ib puag ncig, tuaj yeem hloov kho kev tsim kho kev lag luam thiab yog lwm kauj ruam ntawm kev tsim khoom ruaj khov.
Graphene yog ib qho khoom muaj zog tshaj plaws uas paub txog science; nws yog kwv yees li 200 zaus qhov muaj zog tshaj li hlau. Graphene muaj ib txheej ntawm cov pa roj carbon atoms (nws tseem hu ua ob-kab thiab ob). Vim cov qauv no, nrog rau kev coj ua "tshwj xeeb" ntawm cov khoom siv hluav taws xob, cov khoom siv muaj qhov zoo tshaj plaws ntawm lub cev kev ua tau zoo (ntxiv rau qhov muaj zog super): cov hluav taws xob muaj zog thiab thermal conductivity, loj tshwj xeeb thaj tsam thaj chaw, pob tshab, tshuaj lom neeg ruaj khov.
Thawj thawj zaug, graphene tau txais nyob rau xyoo 2004 hauv University of Manchester los ntawm ob tus neeg tuaj txawv teb chaws tuaj hauv tebchaws Russia, MIPT kawm tiav Andrey Geim thiab Konstantin Novoselov. Rau lawv cov kev sim, lawv tau txais qhov khoom plig Nobel hauv Physics xyoo 2010.
