He māmā loa nā ʻili kalapona e like me ka graphene akā he mea ikaika loa me ka hiki ke hoʻohana maikaʻi loa, akā he paʻakikī paha ke hana ʻana, koi pinepine i ka nui o ka hana kanaka a me nā hoʻolālā e hoʻopau manawa ai, a he pipiʻi nā ʻano hana a ʻaʻole pili i ke kaiapuni.
Me ka hana ʻana o ka nui o ka graphene, i mea e lanakila ai i nā pilikia i loaʻa i ka hoʻokō ʻana i nā ʻano unuhi o kēia manawa, ua hoʻomohala nā mea noiʻi ma ke Kulanui ʻo Ben Gurion o Negev ma ʻIseraʻela i kahi ʻano unuhi graphene "ʻōmaʻomaʻo" hiki ke hoʻopili ʻia i kahi ākea o nā kahua, me nā optics, electronics, ecology a me biotechnology.
Ua hoʻohana nā kānaka noiʻi i ka hoʻolaha mechanical e unuhi i ka graphene mai ka striolite mineral maoli. Ua ʻike lākou e hōʻike ana ka mineral hypophyllite i nā manaʻolana maikaʻi i ka hana ʻana i ka graphene ʻoihana a me nā mea like me graphene.
ʻOkoʻa paha ka nui o ke kalapona o ka hypomphibole. Wahi a ka nui o ke kalapona, hiki i ka hypomphibole ke loaʻa nā mana noi like ʻole. Hiki ke hoʻohana ʻia kekahi mau ʻano no ko lākou mau waiwai catalytic, aʻo nā ʻano ʻē aʻe he mau waiwai bactericidal.
ʻO nā ʻano hoʻonohonoho o ka hypopyroxene e hoʻoholo i kā lākou noi i ke kaʻina hana hoʻemi oxidation, a hiki ke hoʻohana ʻia no ka hana ʻana o ka umu pahū a me ka hana ferroalloy o ka hao hao (silicon kiʻekiʻe).
Ma muli o kona mau ʻano kino a me nā ʻano mechanical, ka nui o ka nui, ka ikaika maikaʻi a me ke kūpaʻa ʻana i ka ʻaʻahu, loaʻa i ka hypophyllite ka hiki ke hoʻopili i nā ʻano mea ola like ʻole, no laila hiki ke hoʻohana maoli ʻia ma ke ʻano he mea kānana. Ua hōʻike pū ia i ka hiki ke hoʻopau i nā ʻāpana radical manuahi e hoʻohaumia paha i nā kumu wai.
Hōʻike ka hypopyroxene i ka hiki ke hoʻomaʻemaʻe a hoʻomaʻemaʻe i ka wai mai nā bacteria, spores, nā microorganisms maʻalahi a me nā algae uliuli-ʻōmaʻomaʻo. Ma muli o kona mau waiwai catalytic a me ka hoʻemi ʻana, hoʻohana pinepine ʻia ka magnesia ma ke ʻano he adsorbent no ka mālama ʻana i ka wai ʻino.
(a) Hoʻonui ʻia ʻo X13500 a me (b) Kiʻi TEM hoʻonui ʻia ʻo X35000 o ka hāpana hypophyllite i hoʻopuehu ʻia. (c) Ka laulā Raman o ka hypophyllite i mālama ʻia a me (d) Ka laulā XPS o ka laina kalapona i ka laulā hypophyllite
Ka unuhi ʻana o Graphene
No ka hoʻomākaukau ʻana i nā pōhaku no ka unuhi ʻana o ka graphene, ua hoʻohana nā mea ʻelua i kahi microscope electron scanning (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 ka haku mele ʻana o ke ʻano a me ke alo o nā minelala ʻē aʻe i loko o ka hypomphibole.
Ma hope o ka pau ʻana o ka nānā ʻana a me ka hoʻomākaukau ʻana o ka laʻana, ua hiki i nā mea noiʻi ke unuhi i ka graphene mai ka diorite ma hope o ka hana ʻana i ka laʻana mai Karelia me ka hoʻohana ʻana i kahi mea hoʻomaʻemaʻe ultrasonic kikohoʻe.
Ma muli o ka hiki ke hana ʻia ka nui o nā laʻana me ka hoʻohana ʻana i kēia ʻano hana, ʻaʻohe pilikia o ka haumia lua, a ʻaʻole koi ʻia nā ʻano hana laʻana ma hope.
ʻOiai ua ʻike nui ʻia nā waiwai kupaianaha o ka graphene ma ke kaiāulu noiʻi ʻepekema ākea, ua hoʻomohala ʻia nā ʻano hana hana a me ka synthesis he nui. Eia nō naʻe, he nui o kēia mau ʻano hana he mau kaʻina hana multi-step a i ʻole e koi ana i ka hoʻohana ʻana i nā kemika a me nā mea oxidizing a me nā mea hōʻemi ikaika.
ʻOiai ua hōʻike ʻo graphene a me nā kiʻiʻoniʻoni kalapona ʻē aʻe i ka hiki ke hoʻohana nui ʻia a ua hoʻokō i ka holomua o ka R&D, ke hoʻomohala ʻia nei nā kaʻina hana e hoʻohana ana i kēia mau mea. ʻO kahi hapa o ka pilikia, ʻo ia ka hana ʻana i ka unuhi ʻana o ka graphene i mea kūpono i ke kumukūʻai, ʻo ia hoʻi, ʻo ka loaʻa ʻana o ka ʻenehana hoʻolaha kūpono ke kī.
He hana luhi kēia ʻano hoʻopuehu a hana ʻino hoʻi i ke kaiapuni, a hiki i ka ikaika o kēia mau ʻenehana ke hana i nā hemahema i ka graphene i hana ʻia, a laila e hōʻemi ana i ka maikaʻi maikaʻi loa o ka graphene.
ʻO ka hoʻohana ʻana o nā mea hoʻomaʻemaʻe ultrasonic i ka synthesis graphene e hoʻopau i nā pilikia a me nā kumukūʻai e pili ana me nā ʻano hana multi-step a me nā kemika. ʻO ka hoʻopili ʻana i kēia ʻano hana i ka mineral hypophyllite kūlohelohe i hoʻomākaukau i ke ala no kahi ala hou e pili ana i ke kaiapuni o ka hana ʻana i ka graphene.
