Graphene ni iki?
Graphene nigikoresho gishya cyibishashara cyibishashara cyakozwe no gupakira hafi ya atome ya karubone imwe. Muyandi magambo, ni ibintu bibiri bya karubone kandi ni ibintu bimwe umubiri wa heteromorphic umubiri wa karubone. Umubumbe wa molekile ya graphene ni 0.142 nm gusa, naho intera ya kirisiti ni 0.335 nm
Abantu benshi ntabwo bafite igitekerezo cyigice cya nano. Nano nigice cyuburebure. Nano imwe ni nka 10 kugeza kuri metero kare 9. Ni ngufi cyane kuruta bagiteri kandi nini nka atome enye. Ibyo ari byo byose, ntidushobora kubona ikintu cya 1 nm n'amaso yacu yambaye ubusa. Tugomba gukoresha microscope. Ivumburwa rya nanotehnologiya ryazanye abantu bashya iterambere ryiterambere, kandi graphene nayo ni tekinoroji ikomeye ihagarariye.
Kugeza ubu, graphene nuruvange ruto cyane rwabonetse mwisi yabantu. Umubyimba wacyo ni muremure gusa nka atome imwe. Mugihe kimwe, nigikoresho cyoroshye kandi nuyobora amashanyarazi meza kwisi.
Umuntu na graphene
Ariko, amateka yabantu na graphene mubyukuri yamaze igice kirenga ikinyejana. Nko mu 1948, abahanga basanze hariho graphene muri kamere. Ariko, muri kiriya gihe, byari bigoye kurwego rwa siyansi nikoranabuhanga gukuramo graphene uhereye kumurongo umwe, bityo izo graphene zashyizwe hamwe, zerekana imiterere ya grafite. Buri mm 1 ya grafite irimo hafi miliyoni 3 za graphene.
Ariko igihe kinini, graphene yafatwaga nkaho itabaho. Abantu bamwe batekereza ko ari ibintu abahanga batekereza gusa, kuko niba koko graphene ibaho, kuki abahanga badashobora kuyikuramo bonyine?
Kugeza 2004, abahanga Andre Geim na Konstantin Volov bo muri kaminuza ya Manchester mu Bwongereza babonye uburyo bwo gutandukanya graphene. Basanze niba flake ya grafite yakuwe kuri grafite ya pyrolytike yerekanwe cyane, noneho impande zombi za flake ya grafite zometse kuri kaseti idasanzwe, hanyuma kaseti irashwanyaguzwa, ubu buryo bwashoboraga gutandukanya neza flake ya grafite.
Nyuma yibyo, ukeneye gusa gusubiramo ibikorwa byavuzwe haruguru ubudasiba kugirango urupapuro rwa grafite mumaboko yawe rworohe kandi rworoshye. Hanyuma, urashobora kubona urupapuro rwihariye rugizwe na atome ya karubone gusa. Ibikoresho biri kuriyi mpapuro ni graphene. Andre Geim na Konstantin Novoselov na bo batsindiye igihembo cyitiriwe Nobel kubera kuvumbura graphene, kandi abavuga ko graphene itabaho bakubiswe mu maso. None se kuki graphene ishobora kwerekana ibiranga?
Graphene, umwami wibikoresho
Graphene imaze kuvumburwa, yahinduye rwose imiterere yubushakashatsi bwa siyansi kwisi yose. Kuberako graphene yerekanye ko ari ibintu byoroshye cyane kwisi, garama imwe ya graphene irahagije kugirango ikingire ikibuga gisanzwe cyumupira wamaguru. Mubyongeyeho, graphene nayo ifite ubushyuhe bwiza cyane bwumuriro n amashanyarazi.
Inenge yuzuye yubusa ya graphene ifite ubushyuhe bukomeye cyane, kandi nubushyuhe bwumuriro buri hejuru ya 5300w / MK (w / m · dogere: ukeka ko umubyimba umwe wibikoresho ari 1m hamwe nubushyuhe bwubushyuhe hagati ya impande ebyiri ni 1C, ibi bikoresho birashobora gutwara ubushyuhe bwinshi binyuze mubuso bwa 1m2 mumasaha), Nibikoresho bya karubone bifite ubushyuhe bwinshi cyane buzwi n'abantu.
