ʻO nā kiʻiʻoniʻoni kalapona e like me ka graphene he māmā loa akā ikaika loa nā mea me ka hiki ke hoʻohana maikaʻi ʻia, akā paʻakikī paha ka hana ʻana, makemake pinepine i ka nui o ka manpower a me nā hoʻolālā manawa, a he pipiʻi nā ʻano hana a ʻaʻole pili kaiapuni.
Me ka hana ʻana i ka nui o ka graphene, i mea e lanakila ai i nā pilikia i loaʻa i ka hoʻokō ʻana i nā ʻano hana unuhi o kēia manawa, ua hoʻomohala nā mea noiʻi ma ke Kulanui ʻo Ben Gurion o ka Negev i ka ʻIseraʻela i kahi ʻano "'ōmaʻomaʻo" graphene extraction i hiki ke hoʻohana ʻia i kahi ākea ākea. o nā kahua, me ka optics, electronics, ecology and biotechnology.
Ua hoʻohana nā mea noiʻi i ka hoʻopuehu mechanical e unuhi i ka graphene mai ka mineral striolite maoli.Ua ʻike lākou ʻo ka mineral hypophyllite e hōʻike ana i nā manaʻo maikaʻi i ka hana ʻana i ka graphene-scale a me nā mea like me ka graphene.

He ʻokoʻa paha ka ʻike kalapona o ka hypomphibole.Wahi a ka ʻike kalapona, hiki i ka hypomphibole ke loaʻa i nā mana hoʻohana like ʻole.Hiki ke hoʻohana ʻia kekahi mau ʻano no kā lākou waiwai catalytic, aʻo nā ʻano ʻē aʻe he mau waiwai bactericidal.
ʻO nā hiʻohiʻona o ka hypopyroxene e hoʻoholo i kā lākou noi i ke kaʻina hana oxidation-reduction, a hiki ke hoʻohana ʻia no ka hana ʻana o ka umu ahi a me ka hana ferroalloy o ka hao (kiʻekiʻe kiʻekiʻe).
Ma muli o kona mau kino kino a me ka mechanical, bulk density, ikaika maikaʻi a me ke kū'ē kū'ē, hiki i ka hypophyllite ke hoʻopili i nāʻano mea olaola, no laila hiki ke hoʻohana maoliʻia e like me ke kānana.Ua hōʻike pū ʻia ka hiki ke hoʻopau i nā ʻāpana radical manuahi e hoʻohaumia i nā kumu wai.
Hōʻike ka hypopyroxene i ka hiki ke hoʻomaʻemaʻe a hoʻomaʻemaʻe i ka wai mai ka bacteria, spores, microorganisms maʻalahi a me nā algae uliuli-'ōmaʻomaʻo.Ma muli o kāna mau catalytic kiʻekiʻe a me ka hoʻohaʻahaʻa waiwai, hoʻohana pinepine ʻia ka magnesia ma ke ʻano he adsorbent no ka mālama ʻana i ka wai.

(a) X13500 hoʻonui a me (b) X35000 kiʻi TEM o ka hāpana hypophyllite i hoʻopuehu ʻia.(c) Raman spectrum o ka hypophyllite i mālama ʻia a me (d) XPS spectrum o ka laina kalapona ma ka hypophyllite spectrum
ʻOhi graphene
No ka hoʻomākaukau ʻana i nā pōhaku no ka unuhi ʻana i ka graphene, ua hoʻohana nā mea ʻelua i kahi scanning electron microscope (SEM) e nānā i nā haumia metala kaumaha a me ka porosity i loko o nā laʻana.Ua hoʻohana pū lākou i nā ʻano hana hoʻokolohua ʻē aʻe e nānā i ke ʻano o ka hoʻokumu ʻana a me ka loaʻa ʻana o nā minela ʻē aʻe i loko o ka hypomphibole.
Ma hope o ka pau ʻana o ka nānā ʻana a me ka hoʻomākaukau ʻana, ua hiki i nā mea noiʻi ke unuhi i ka graphene mai ka diorite ma hope o ka hoʻomaʻamaʻa ʻana i ka hāpana mai Karelia me ka hoʻohana ʻana i ka mīkini hoʻomaʻemaʻe ultrasonic.
No ka mea hiki ke hana ʻia ka nui o nā laʻana me ka hoʻohana ʻana i kēia ʻano, ʻaʻohe pilikia o ka luaʻi lua, a ʻaʻole koi ʻia nā ʻano hana hoʻohālike ma hope.
No ka mea, ua ʻike nui ʻia nā waiwai kupaianaha o ka graphene i loko o ke kaiāulu noiʻi ʻepekema ākea, ua kūkulu ʻia nā ʻano hana hana a me ka synthesis.Eia nō naʻe, ʻo ka hapa nui o kēia mau kaʻina hana he mau kaʻina hana a i ʻole e koi i ka hoʻohana ʻana i nā kemika a me nā mea hoʻoheheʻe ikaika a hoʻemi.
ʻOiai ua hōʻike ʻo graphene a me nā kiʻi kalapona ʻē aʻe i ka hiki ke hoʻohana nui a loaʻa i ka kūleʻa R&D pili, ke hoʻomau nei nā kaʻina hana e hoʻohana ana i kēia mau mea.ʻO kahi ʻāpana o ka luʻi ʻo ka hana ʻana i ka graphene extraction cost-effective, ʻo ia hoʻi ka ʻimi ʻana i ka ʻenehana hoʻopuehu kūpono ke kī.
ʻO kēia ʻano hoʻopuehu a i ʻole synthesis he hana paʻakikī a pili ʻole i ke kaiapuni, a hiki i ka ikaika o kēia mau ʻenehana ke hoʻopōʻino i ka graphene i hana ʻia, a laila e hōʻemi i ka maikaʻi maikaʻi o ka graphene.
ʻO ka hoʻohana ʻana i nā mea hoʻomaʻemaʻe ultrasonic i ka graphene synthesis e hoʻopau i nā pilikia a me nā kumukūʻai e pili ana i nā ʻano hana he nui a me nā hana kemika.ʻO ka hoʻohana ʻana i kēia ʻano hana i ka mineral hypophyllite kūlohelohe i hoʻolalelale i ke ala no ka hana ʻana i ka graphene hou.
