I roto i te mara o te ine ine kounga teitei, ko te tika te paearu matua mō te ine i te uara o ngā taputapu. I ngā tau tata nei, kua whakarērea e te 95% o ngā taputapu ine kounga teitei ngā turanga rino tuku iho, ā, kua whakamahia ngā turanga karāhe. Kei muri i tēnei panonitanga ahumahi ko te whanaketanga hangarau i puta mai i ngā āhuatanga whakamātao taumata-nano o ngā turanga karāhe. Ka tātarihia hohonutia e tēnei tuhinga ngā painga ahurei o ngā turanga karāhe, ā, ka hurahia te mea ngaro kei muri i tō rātou noho hei "tino pai hou" o ngā taputapu ine kounga teitei.
Ngā herenga o ngā turanga rino maka: He uaua ki te whakatutuki i ngā whakaritenga ine kounga teitei
I mua, ko te rino maka te rauemi matua mō te turanga o ngā taputapu ine, ā, i whakamahia whānuitia nā te iti o te utu me te ngāwari o te tukatuka. Heoi, i roto i ngā āhuatanga ine teitei, kei te piki haere te kitea o ngā herenga o te rino maka. I tetahi taha, he ngoikore te pumau o te rino maka, me te tauwehenga whānui wera tae atu ki te 11-12 ×10⁻⁶/℃. Ina whakaputa wera te taputapu i te wā e whakahaerehia ana, ina huri rānei te pāmahana taiao, ka ngāwari ki te whakarerekē i te pāmahana, ka puta te rerekētanga o te tohutoro ine. I tetahi atu taha, he moroiti ngā pūwero o roto o te rino maka, ā, kāore i te rawaka tana mahi whakaiti wiri, ka kore e taea te mimiti pai i te pokanoa wiri o waho. Ina whakaputa wiri te whakahaere o ngā taputapu mīhini me te nekehanga o ngā waka i roto i te awheawhe, ka tukuna e te turanga rino maka ngā wiri ki ngā taputapu ine, ka puta he rerekētanga o ngā raraunga ine, ā, ka uaua ki te whakatutuki i ngā whakaritenga ine tino tika i ngā taumata nanometer me te micrometer.
Ngā āhuatanga whakamākū nanoscale o ngā turanga karāhe: Te taurangi matua mō te ine tika
He kōhatu tūturu te karāneti i hangaia mā roto i ngā tukanga whenua mō ngā rau miriona tau. He kikī ngā tioata kohuke o roto, ā, he matotoru, he ōrite hoki tōna hanganga, e whakawhiwhi ana i ngā āhuatanga whakamākūkū nano-tauine tino pai. Ina tukuna ngā wiri o waho ki te turanga karāneti, ka taea e tōna hanganga iti o roto te huri tere i te kaha wiri hei kaha wera, ka tutuki ai te whakaiti pai. Ki te whakatauritea ki te rino maka, ka poto ake te wā urupare wiri o ngā turanga karāneti mā te neke atu i te 80%, ā, ka taea e rātou te hoki ki tōna āhua pumau i roto i te wā poto rawa, ka ārai i te pānga o te wiri ki te tika o te ine o ngā taputapu ine.
Mai i te tirohanga moroiti, he nui ngā rohe kōhatu iti me ngā matūriki kohuke kei roto i te hanganga tioata o te karāhe, ā, ko ēnei āhuatanga hanganga ka hanga he "whatunga mimiti wiri" tūturu. Ina horapa ngā ngaru wiri i roto i te karāhe, ka tukituki, ka whakaata, ka marara ki ēnei rohe kōhatu me ngā matūriki i ngā wā maha. Ka pau tonu te kaha wiri i roto i tēnei tukanga, ā, ka tutuki te pānga o te whakaiti wiri. E whakaatu ana ngā rangahau ka taea e te turanga karāhe te whakaiti i te kaha wiri ki raro iho i te kotahi-tekau o te taketake, ka whakarato i tētahi taiao ine pumau mō ngā taputapu ine.
Ētahi atu painga o ngā turanga karāhe: Ka tutuki katoa ngā hiahia teitei
Haunga ōna āhuatanga whakamākūkū nano-tauine tino pai, he maha ngā painga o te turanga karāhe, he mea pai mō ngā taputapu ine kounga teitei. He tino iti tōna tauwehenga whakawhanui wera, 5-7 ×10⁻⁶/℃ anake, ā, kāore e pāngia e ngā huringa pāmahana. Ka taea e ia te pupuri i te rahi me te āhua pumau i raro i ngā āhuatanga taiao rerekē, kia tika ai te tohutoro ine. I taua wā, he pakeke te karāhe (me te pakeke Mohs o te 6-7) me te ātete kaha ki te kakahu. Ahakoa te whakamahinga roa, ka taea tonu e tōna mata te pupuri i te āhua papatahi tino tika, ka whakaiti i te auau o te tiaki me te whakatikatika taputapu. Hei tāpiri, he pumau ngā āhuatanga matū o te karāhe, ā, kāore e waikura ngāwari e ngā matū waikawa, kawakore rānei, kia pai ai mō ngā taiao ahumahi uaua.
Kua whakamanahia e ngā mahi ahumahi te uara tino pai o ngā turanga karāhe
I roto i te ao hanga haurua-haurua, kua tae te rahi o ngā maramara ki te wā nanoscale, ā, he tino teitei ngā whakaritenga mō te tika o ngā taputapu ine. Whai muri i te whakakapinga o ngā taputapu ine e tētahi umanga haurua-haurua rongonui o te ao ki te turanga rino maka ki te turanga karāhe, ka heke te hapa ine mai i te ±5μm ki te ±0.5μm, ā, ka piki ake te tere hua hua mā te 12%. I roto i te ao rererangi, ko ngā taputapu ine kounga teitei e whakamahia ana mō te kimi i te āhua me te tūnga o ngā wāhanga, whai muri i te tango i ngā turanga karāhe, ka ārai i te pokanoa wiri, ka whakarite i te tika o te tukatuka o ngā wāhanga matua pēnei i ngā mata o te miihini rererangi me ngā anga o te tinana, ā, ka whakarato i te taurangi kaha mō te haumaru me te pono o ngā hua rererangi.
I te whakapai tonu i ngā whakaritenga mō te tika o te ine i roto i te umanga hangahanga teitei, kei te hurihia ngā paerewa hangarau o ngā taputapu ine e ngā turanga karāhe, me ō rātou āhuatanga whakaiti i te tauine nano me ngā painga mahi whānui. Ko te nekehanga mai i te rino maka ki te karāhe ehara i te whakapai ake i ngā rauemi anake; he hurihanga ahumahi anō hoki e akiaki ana i te hangarau ine tika ki ngā taumata hou.
