He tino māmā engari he tino kaha ngā kiriata waro pērā i te graphene, he tino pai te kaha ki te whakamahi, engari he uaua pea ki te hanga, he nui te mahi a te tangata me ngā rautaki e pau ana te wā, ā, he nui te utu mō ngā tikanga, ā, kāore i te pai ki te taiao.
Hei whakakore i ngā uauatanga o te whakatinanatanga o ngā tikanga tango o nāianei, nā te nui o te graphene i whakaputaina, kua whakawhanakehia e ngā kairangahau o Te Whare Wānanga o Ben Gurion o Negev i Iharaira tētahi tikanga tango graphene "matomato" ka taea te whakamahi ki te whānuitanga o ngā mara, tae atu ki ngā tirohanga, ngā hikohiko, te rauropi me te hangarau koiora.
I whakamahia e ngā kairangahau te marara ā-pūkaha hei tango i te graphene mai i te striolite kohuke tūturu. I kitea e rātou he pai ngā tūmanakohanga o te kohuke hypophyllite ki te whakaputa i te graphene tauine ahumahi me ngā matū rite ki te graphene.
Tērā pea he rerekē te nui o te waro i roto i te hypomphibole. E ai ki te nui o te waro, he rerekē ngā pūmanawa tono o te hypomphibole. Ka taea te whakamahi i ētahi momo mō ō rātou āhuatanga whakatere, ko ētahi atu he āhuatanga patu huakita.
Ko ngā āhuatanga hanganga o te hypopyroxene e whakatau ana i tā rātou whakamahinga i roto i te tukanga whakaiti-waikura, ā, ka taea hoki te whakamahi mō te hanga oumu pupuhi me te hanga rino whakarewa (silicon teitei) i roto i te ferroalloy.
Nā ōna āhuatanga ā-tinana, ā-pūkaha hoki, tōna matotoru, tōna kaha me tōna ātete ki te kakahu, ka taea hoki e te hypophyllite te mimiti i ngā momo matū rauropi, nō reira ka taea te whakamahi hei rauemi tātari. I whakaatuhia hoki tōna kaha ki te whakakore i ngā matūriki rauropi kore utu ka poke pea i ngā puna wai.
E whakaatu ana te hypopyroxene i te kaha ki te patu huakita me te pure i te wai mai i ngā huakita, ngā pua, ngā moroiti māmā me ngā rimurimu kikorangi-kakariki. Nā ōna āhuatanga whakatere me te whakaiti teitei, ka whakamahia te konupūmā hei mea mimiti mō te maimoatanga wai para.
(a) Te whakanui X13500 me te (b) te whakaahua TEM whakanui X35000 o te tauira hypophyllite kua marara. (c) Te whānuitanga Raman o te hypophyllite kua rongoatia me te (d) te whānuitanga XPS o te rārangi waro i roto i te whānuitanga hypophyllite
Te tango i te karāpene
Hei whakarite i ngā toka mō te tango i te graphene, i whakamahia e rāua he karu hiko matawai (SEM) hei tirotiro i ngā poke me te porosity o te konganuku taumaha i roto i ngā tauira. I whakamahia anō hoki e rāua ētahi atu tikanga taiwhanga hei tirotiro i te hanganga whānui me te aroaro o ētahi atu kohuke i roto i te hypomphibole.
I muri i te otinga o te tātari me te whakarite tauira, ka taea e ngā kairangahau te tango i te graphene mai i te diorite i muri i te tukatuka ā-mīhini i te tauira mai i Karelia mā te whakamahi i tētahi kaihoroi ultrasonic mamati.
I te mea ka taea te tukatuka i te tini o ngā tauira mā te whakamahi i tēnei tikanga, kāore he mōrearea o te poke tuarua, ā, kāore e hiahiatia he tikanga tukatuka tauira i muri mai.
Nā te mea kua mōhiotia whānuitia ngā āhuatanga whakamiharo o te graphene i roto i te hapori rangahau pūtaiao whānui, he maha ngā tikanga whakaputa me te hanga kua whakawhanakehia. Heoi, he maha o ēnei tikanga he tukanga maha-taahiraa, he hiahia rānei ki te whakamahi i ngā matū me ngā matū whakahāora me te whakaiti kaha.
Ahakoa kua whakaatuhia e te graphene me ētahi atu kiriata waro he kaha nui ki te whakamahi, ā, kua angitu hoki ki te R&D, kei te whanake tonu ngā tukanga e whakamahi ana i ēnei rauemi. Ko tētahi o ngā wero ko te whakaiti i te utu o te tango graphene, ko te tikanga ko te kimi i te hangarau horapa tika te mea nui.
He mahi uaua tēnei tikanga horapa, tikanga hanga rānei, ā, he kino ki te taiao, ā, ka taea hoki e te kaha o ēnei hangarau te whakararu i te graphene kua whakaputaina, ka whakaitihia ai te kounga pai e tumanakohia ana mō te graphene.
Mā te whakamahinga o ngā kaihoroi ultrasonic i roto i te hanga graphene ka whakakorea ngā mōrearea me ngā utu e pā ana ki ngā tikanga maha-taahiraa me ngā tikanga matū. Nā te whakamahinga o tēnei tikanga ki te kohuke hypophyllite tūturu i whakatakoto te ara mō tētahi huarahi hou e pai ana ki te taiao mō te whakaputa graphene.
