Hoʻolauna iā Graphene
ʻO Graphene kahi ʻāpana ʻelua (2ʻO D) ʻano kalapona i hoʻonohonoho ʻia i loko o kahi papa hoʻokahi o nā mana i loko o kahi lattice hexagonal hou. Ua hoʻokaʻawale mua ʻia ma 2004 na Andre Geim a me Konstantin Novoselov ma ke Kulanui o Manchester, i loaʻa i ka Nobel Prize in Physics in 2010 no ka lakou mau hoao ana. ʻO ka Graphene ka mea nui he ʻātoma-ʻano honeycomb mesh o nā ʻātoma kalapona, ʻo ia ka mea e lilo ai i lālā o ka ʻohana structural fullerene, ʻo ia hoʻi ka graphite, lanahu, carbon nanotubes, a me ka fullerenes (pōpō pōkā).
Nā hiʻohiʻona o Graphene
Ka ikaika: ʻO Graphene kekahi o nā mea ikaika loa i ʻike ʻia, me ka ikaika tensile a puni 130 gigapascals (GPa), ʻoi aku ka ikaika ma mua o ke daimana a ʻoi aku ka ikaika ma mua o ke kila.
ʻoluʻolu: ʻOiai kona ikaika, He maʻalahi hoʻi ka graphene a hiki ke pio a ʻōwili ʻole ʻia me ka haki ʻole.
ʻO ka hoʻokō: He mea lawe uila maikaʻi loa ia, me ka neʻe ʻana o ka electron 200 ʻoi aku ka nui ma mua o ka silika.
ʻO ka hoʻoili wela: He kiʻekiʻe loa ka conductivity wela o ka Graphene, 'o ia ho'i, hiki iā ia ke lawe i ka wela me ka maika'i loa.
ʻAlohilohi: Aneane maopopo loa ka graphene, omo wale no 2.3% o ka malamalama, ʻo ia ka mea kūpono no ka hoʻohana ʻana i nā uila uila.
Paʻa Kemika: He paʻa kemika a hiki ke pale aku i ka oxidation i ka ea, e hoʻonui ai i kona lōʻihi.
Wahi Kiekie: Loaʻa ka ʻili o ka graphene a hiki i ka 2630 mika huinaha, He mea pono ia no nā noi e koi ana i nā wahi ākea nui.
Nā noi o Graphene
Mea uila: Hiki i ka Graphene ke hoʻololi i nā mea uila ma muli o kona kiʻekiʻe electron neʻe a me ka ʻike, kūpono ia no nā pale paʻi, kiʻi photovoltaic, a me nā mea uila uila kiʻekiʻe.
Waihona ikehu: Hiki iā ia ke hoʻomaikaʻi i ka hana o nā pihi a me nā supercapacitors ma muli o kona kiʻekiʻe kiʻekiʻe a me ka conductivity.
Mea Hana Hui: Ma ka hoʻohui ʻana i ka graphene i nā plastics, metala, a i ʻole nā keramika, hiki ke hoʻonui i ka mechanical i ka hopena o nā composites, wela, a me nā waiwai uila.
ʻEnekinia Biomedical: ʻO ka biocompatibility o Graphene a me ka hiki ke lawe i nā lāʻau lapaʻau e pono ai no nā ʻōnaehana lawe lāʻau a me ka ʻenekinia kiko.
Hoomaemae Wai: Hiki i nā membrane kumu graphene ke kānana i nā haumia mai ka wai, me ka paʻakai, bacteria, a me nā mea hoʻomaʻi.
Nā mea ʻike: Hiki i nā mea ʻike graphene ke ʻike i ka nui o nā kinoea a i ʻole biomolecules, e hoʻohana pono iā lākou i ka nānā ʻana i ke kaiapuni a me nā diagnostics olakino.
Mea Elele Hiki: ʻO kona maʻalahi a me ka conductivity e kūpono ia no nā hāmeʻa hiki ke hoʻohana a me nā hōʻike maʻalahi.
ʻIkepili Hui
ʻO Graphene Aerogels kahi mea hoʻolako waiwai kemika honua & mea hana me ka ʻoi aku o 12 mau makahiki-ʻike i ka hāʻawi ʻana i ka graphene kiʻekiʻe kiʻekiʻe, airgel a me nā huahana pili.
He keʻena ʻenehana loea ko ka hui a me ka Quality Supervision Department, he hale hana i hoolako pono ia, a hoʻolako ʻia me nā lako hoʻāʻo kiʻekiʻe a me ke kikowaena lawelawe mea kūʻai aku ma hope o ke kūʻai aku.
Inā ʻoe e ʻimi nei i ka graphene kiʻekiʻe, airgel a me nā huahana pili, eʻoluʻolu e leka uila iā mākou a iʻole e kaomi i nā huahana i makemakeʻia e hoʻouna i kahi nīnau.

Hoʻouna
Hiki ke hoʻouna ʻia ma ke kai, ma ka lewa, a i ʻole ma ka hōʻike ʻana iā ASAP i ka wā e loaʻa ai ka uku.
Nā nīnau nīnau e pili ana iā Graphene
Pehea e hana ʻia ai ka graphene?
Hiki ke hana ʻia ka graphene ma nā ʻano he nui, me ka exfoliation mechanical (ka ʻili ʻana i nā papa mai ka graphite), ka waiho ʻana o ka mahu kemika (CVD), a me ka hoemi kemika o ka graphene oxide.
He mea make ka graphene?
Hōʻike nā haʻawina o kēia manawa e loaʻa paha i ka graphene kekahi mau pilikia ʻona, oi loa aku ina inhaled, akā, pono ka noiʻi hou aʻe e hoʻomaopopo pono i kona mau hopena olakino.
Hiki ke hana nui ʻia ka graphene?
ʻAe, ʻO nā ala e like me CVD e ʻae i ka hana ʻana o ka graphene ma kahi ʻano nui, ʻoiai e paʻakikī ana ka loaʻa ʻana o ka maikaʻi like ʻole a me nā ʻāpana nui.
He aha ke kumukūʻai o ka graphene?
Hoʻololi nui ke kumukūʻai ma muli o ke ʻano hana a me ka maʻemaʻe e pono ai, akā, ua emi nui nā kumukūʻai ma muli o ka hoʻomaikaʻi ʻana o nā ʻenehana hana.
Loaʻa i ka graphene nā waiwai magnetic?
ʻAʻole magnetic ka graphene maʻemaʻe, akā hiki ke hoʻohana ʻia e hōʻike i nā waiwai magnetic ma o ka doping a i ʻole nā hopena pili me nā mea magnetic.
