Hauv Nanotube Science, Puas Yog Boron Nitride Cov Carbon Tshiab?
May 09, 2023
Engineers ntawm MIT thiab University of Tokyo tau tsim cov qauv centimeter-teev, loj txaus rau lub qhov muag pom, uas tau ntim nrog ntau pua txhiab tus hollow aligned fibers, lossis nanotubes, ua los ntawm hexagonal boron nitride.
Hexagonal boron nitride, los yog hBN, yog ib qho khoom siv atom-thin uas tau raug coined "dawb graphene" rau nws cov pob tshab thiab nws zoo sib xws rau carbon-based graphene hauv cov qauv molecular thiab lub zog. Nws tuaj yeem tiv taus qhov kub siab dua li graphene, thiab yog hluav taws xob insulating, tsis yog conductive. Thaum hBN yog dov rau hauv nanometer-scale raj, los yog nanotubes, nws cov khoom tshwj xeeb yog txhim khu kev qha.
Pab neeg cov txiaj ntsig, luam tawm hnub no hauv phau ntawv xov xwmACS Nano, muab ib txoj hauv kev mus rau fabricating aligned boron nitride nanotubes (A-BNNTs) nyob rau hauv tej. Cov kws tshawb fawb npaj yuav siv cov txheej txheem los tsim cov txheej txheem ntau ntawm cov nanotubes, uas tuaj yeem ua ke nrog lwm cov ntaub ntawv los ua kom muaj zog dua, tiv taus cua sov ntau dua, piv txwv li los tiv thaiv qhov chaw cov qauv thiab cov dav hlau hypersonic.
