M'zaka zaposachedwa, chidwi chaperekedwa kwa Grupheter Waurmaterial. Koma graphene ndi chiyani? Tangoganizirani chinthu chomwe ndi cholimba cha 200 kuposa chitsulo, koma 1000 nthawi zopepuka kuposa pepala.
Mu 2004, asayansi awiri ochokera ku yunivesite ya Manchester, Andrei Geim ndi Konstantin Novofete. Inde, zomwezi zomwe mumapeza pa PANSI. Amafuna chidwi ndi nkhaniyi ndipo amafuna kudziwa ngati zitha kuchotsedwa mu umodzi. Chifukwa chake adapeza chida chachilendo: tepi ya Duct.
"Mumayika [tepi] yoposa graphite kapena micA kenako kusenda bbc pamwamba," adalongosola ku BBC. Flaphite Flakes imauluka pa tepi. Kenako pindani tepiyo pakati ndikuwupilira pa pepala pamwamba, kenako pezani. Kenako mumabwereza izi katatu kapena 20.
"Nthawi iliyonse ma flakes amayamba kucheperachepera. Pomaliza, ma flake opyapyala amakhalabe pa lamba. Mumasungunula tepi ndipo chilichonse chimasungunuka."
Modabwitsa, njira ya tepi idagwira ntchito zodabwitsa. Kuyesa kosangalatsa kumeneku kunapangitsa kuti atulutsidwe kwa graphene imodzi.
Mu 2010, Heim ndi Novoselov adalandira mphotho ya Nobel mu sayansi ya Nobel, zomwe zidapangidwa ndi ma atomu a Carbon omwe adakonzedwa mu chitoliro cha hexagol, zofanana ndi waya wa nkhuku.
Chimodzi mwazifukwa zazikulu, ndi zodabwitsa kwambiri. Wosanjikiza wa prisne graphene amawoneka ngati wosanjikiza wa matomu a kaboni adakonzedwa mu mawonekedwe a hexagon. Kapangidwe ka atomiki uchi ndi mphamvu zake zochititsa chidwi.
Graphene ndiwonso wamagetsi. Kutentha, kumapangitsa magetsi bwino kuposa zinthu zina zilizonse.
Mukukumbukira ma atomu a kaboni amene takambirana? Aliyense ali ndi elect electron yowonjezera yotchedwa Piachron. Electron iyi imasunthira momasuka, kulola kuti azichita zophatikizika kudzera pazigawo zingapo za graphene osakanikirana pang'ono.
Kafukufuku waposachedwa ku Graphene ku Massachusetts Institute of Technology (Mit) apeza china chake pafupifupi magile: 1 madigiri 1.1) chimakhala chachikulu.
Izi zikutanthauza kuti imatha kusintha magetsi popanda kukana kapena kutentha, kutsegula zotsetsera zosangalatsa za supercanduction wamtsogolo firiji.
Limodzi mwa mapulogalamu omwe akuyembekezeredwa kwambiri a graphene ali m'mabatire. Chifukwa cha zochitika zake zazikulu zapamwamba, titha kupanga mabatire a graphene omwe amalipiritsa mwachangu komanso nthawi yayitali kuposa mabatire amakono a litiyamu.
Makampani ena akuluakulu monga Samsung ndi Huawei atenga kale njira iyi, ndikuwonetsa kuti apitilize kupita patsogolo pamawada ndi zida zamasiku onse.
"Pofika 2024, timayembekezera kuti zinthu zikhale za graphene kukhale pamsika," anatero Andrea Ferrarin Grapnene Center ndi Wofufuza ku Frapher Flall Stelloppeci Unayamba. Kampaniyo ikugulitsa ma rouros 1 mabizinesi ophatikizika. ntchito. Chiyanjano chimathandizira kukula kwaukadaulo wa graphene.
Ofufuzawo aku Flagrachipe akupanga kale mabatire a graphene omwe amapereka 20% mphamvu zambiri ndi 15% mphamvu kuposa mabatire apamwamba kwambiri. Magulu ena apanga maselo opangidwa ndi graphene omwe alipo 20 peresenti yothandiza potembenuza kuwala kwa dzuwa kukhala magetsi.
Ngakhale pali zinthu zina zoyambirira zomwe zidapangitsa kuti kuthekera kwa graphene, monga zida zamasewera amutu, zabwino zili zikubwera. Monga Ferrari anati: "Tikulankhula za graphene, koma kwenikweni tikulankhula za njira zambiri zomwe zimaphunziridwa. Zinthu zikuyenda molondola."
Nkhaniyi yasinthidwa pogwiritsa ntchito ukadaulo wanzeru zanzeru, zowonekera, komanso zokonzedwa ndi ayoni akonzi.
Mutu Wopanga Masewera Ogulitsa Amagwiritsa Ntchito Zinthu Zodabwitsa. Graphene wa ttnis tt racket imati azikhala 20% yopepuka yomweyo. Awa ndi ukadaulo weniweni!
