He aha te graphene?
Ko te Graphene he mea hangai hexagonal honeycomb lattice hou i hangaia e te tarapi tata o nga ngota waro paparanga kotahi. Arā, he rauemi waro ahu-rua, no te mea kotahi te tinana heteromorphic o te huānga waro. He 0.142 nm anake te herenga ngota ngota o te graphene, a ko te mokowhiti rererangi karaihe he 0.335 nm anake
He maha nga tangata kaore he ariā o te waeine o te nano. Ko te Nano he waeine roa. Kotahi te nano kei te 10 ki te iti te 9 mita tapawha. He poto ake i te huakita, he rite te nui ki te wha ngota. Ahakoa he aha, kare rawa tatou e kite i tetahi mea 1 nm me o tatou kanohi tahanga. Me whakamahi tatou i te microscope. Na te kitenga o te hangarau nano i mau mai nga mara whanaketanga hou ki te tangata, a, he mea tino nui te graphene ki te hangarau.
I tenei wa, ko te graphene te puhui kikokore kua kitea i te ao tangata. He rite noa te matotoru o te ngota kotahi. I te wa ano, koinei hoki te mea maamaa me te kaiarahi hiko pai rawa atu o te ao.
Tangata me te graphene
Heoi, neke atu i te haurua rau tau te hitori o te tangata me te graphene. No te tau 1948, kua kitea e nga kaiputaiao te noho o te graphene i roto i te taiao. Heoi, i taua wa, he uaua mo te taumata pūtaiao me te hangarau ki te tihore i te kawhata mai i te hanganga paparanga kotahi, no reira i whakahiatohia enei graphene, e whakaatu ana i te ahua o te kauwhata. Ia 1 mm o te kauwhata kei roto tata ki te 3 miriona nga paparanga graphene.
Engari mo te wa roa, ka kiia ko te graphene te kore e noho. Ko etahi ka whakaaro he matū noa tenei e whakaarohia ana e nga kaiputaiao, na te mea mena kei te noho tonu te graphene, he aha te take ka kore e taea e nga kaiputaiao te tango takitahi?
Tae noa ki te tau 2004, ka kitea e nga kaiputaiao a Andre Geim me Konstantin Volov mai i te Whare Wananga o Manchester i te UK he huarahi hei wehe i te graphene. I kitea e ratou mena ka tangohia nga tawerewere kauwhata mai i te kauwhata pyrolytic tino aro nui, ka mau nga taha e rua o nga tawerewere kauwhata ki te riipene motuhake, katahi ka haea te riipene, ka taea e tenei tikanga te wehe pai i nga tawerewere kauwhata.
Whai muri i tera, me mahi ano koe i nga mahi o runga ake nei kia angiangi, kia angiangi te pepa kauwhata o to ringaringa. Ka mutu, ka taea e koe te tiki pepa motuhake he ngota waro anake. Ko nga mea kei runga i tenei rau he graphene. I toa ano a Andre Geim raua ko Konstantin Novoselov i te Tohu Nobel mo te kitenga o te graphene, a ko te hunga i kii karekau he graphene ka whiua ki te kanohi. Na te aha e whakaatu ai te graphene i enei ahuatanga?
Ko Graphene, te kingi o nga taonga
I te kitenga o te graphene, ka huri katoa te whakatakotoranga o te rangahau pūtaiao i te ao katoa. Na te mea ko te graphene te mea tino angiangi rawa o te ao, kotahi karamu o te graphene e ranea ana hei kapi i te papa whutupaoro paerewa. I tua atu, he pai rawa atu te wera me te hiko o te graphene.
Ko te graphene papa-kotahi kore koha parakore he tino kaha te kawe i te waiariki, a, he rite te teitei ki te 5300w / MK (w / m · tohu: ki te whakaaro ko te paparanga kotahi o te papanga he 1m me te rereketanga o te pāmahana i waenga i te Ko nga taha e rua he 1C, ka taea e tenei rawa te kawe i te wera nui i roto i te horahanga mata o te 1m2 i te haora), Ko te mea waro me te kawe wera teitei e mohiotia ana e te tangata.
