Kafukufuku watsopano amawonetsa bwino mafilimu abwino

Graphite wamkulu ali ndi mphamvu yabwino kwambiri, kukhazikika kwamafuta, kusinthasintha kwakukulu komanso kwamagetsi, kumapangitsa kuti akhalebe ndi zinthu zofunika kwambiri zapamwamba kwambiri monga mabatire omwe amagwiritsidwa ntchito ngati matelefoni. Mwachitsanzo, mtundu wapadera wa graphite, wolamulidwa kwambiri pyrolytic graphite (hopg), ndi imodzi mwazomwe zimagwiritsidwa ntchito kwambiri mu labotaries. Nkhani. Zojambula zabwinozi zimachitika chifukwa cha kapangidwe ka graphite, komwe kulumikizana kwamphamvu pakati pa kaboni kwambiri kumayiko ena kumathandizira kuti katundu wa graphene ule, ngakhale pang'ono pang'ono pakati pa graphene. Zochita zimabweretsa kusinthasintha kwamphamvu. graphite. Ngakhale Graphite yapezeka kale kwa zaka zoposa 1000 ndi kaphatikizidwe wake waphunziridwa kwa zaka zopitilira 100, mtundu wa zitsanzo zojambula, zonse zachilengedwe komanso zopangidwa, sizikhala zabwino. Mwachitsanzo, kukula kwa madera akulu akulu a Crystal ku zida zojambulajambula nthawi zambiri kumakhala kochepera 1 mm, komwe kumasiyana kwambiri ndi kukula kwa makhiristo ambiri monga makristalo. Kukula kumatha kufikira kuchuluka kwa mita. Kukula kocheperako kwa gryphy kumachitika chifukwa cha kulumikizana pakati pa zigawo za graphite, ndipo kuthwa kwa graphene wosanjikiza sikunakhale zovuta pakukula, motero graphite kumasweka mosavuta m'malire angapo a kristage. . Kuti muthetse vuto lalikululi, pulofesa imachokera ku Ulsan National Institute of Science ya sayansi ya sayansi ya sayansi ya Provices (UNARD) PERTET SINETES, ndipo ena afunsira ma graphitis. filimu, pansi ku inchi. Njira zawo zimagwiritsa ntchito zojambulazo za kristal nickel ngati gawo lapansi, ndipo ma atomu a kaboni amadyetsedwa kumbuyo kwa nickel zojambulazo kudzera mu "njira yosungunuka yosinthika - njira yosinthira-yosiyanasiyana". M'malo mogwiritsa ntchito kakhadi wamakatoni oyendetsa bwino, adasankha zinthu zolimba kaboni kuti athandizire pofotokoza zithunzi. Njira yatsopanoyi imapangitsa kuti zitheke kujambula mafilimu amodzi a kristal okhala ndi mainchesi pafupifupi 1 mainchesi 35, kapena zopitilira 100,000, kapena zigawo zoposa 100,000 m'masiku ochepa. Poyerekeza ndi zitsanzo zonse za graphite, graphite yokongola ili ndi mawonekedwe a ~ 2880 w m-1k-1, kukhala osafunikira kwenikweni pakati pa zigawo. . . .
