Ko ngā rīpene nanocrystalline me ngā rīpene amorphous he rauemi e rua he āhuatanga ahurei, ā, ka kitea te whakamahinga i roto i ngā mara rerekē. E whakamahia ana ēnei rīpene e rua i roto i ngā ahumahi rerekē nā ō rāua āhuatanga motuhake, ā, he mea nui te mārama ki te rerekētanga i waenganui i a rāua hei whakamahi pai i ō rāua pūmanawa.
He rauemi te rīpene nanocrystalline me te hanganga motuhake e titoa ana e ngā kirikiri iti. Ko te nuinga o te wā he iti iho i te 100 nanometer te rahi o ēnei kirikiri, koia te take i tapaina ai te rauemi. He maha ngā painga o te iti o te kirikiri, pērā i te kaha uruhanga aukume teitei ake, te iti o te ngaronga hiko, me te pumau wera nui ake. Mā ēnei āhuatanga karīpene nanocrystallinehe rauemi tino whai hua mō te whakamahi i roto i ngā whakawhiti hiko, ngā ine hiko, me ngā matua aukume.
Mā te whakarei ake i ngā āhuatanga aukume o ngā rīpene nanocrystalline ka taea te whakanui ake i te pai me te mātotoru o te mana i roto i ngā whakawhiti hiko. Ka hua ake tēnei i te whakaiti i te ngaronga o te pūngao i te wā e tuku ana, e tohatoha ana hoki i te mana, ā, ka taea te penapena pūngao me te penapena utu. Mā te whakapai ake i te pumau wera o ngā rīpene nanocrystalline ka taea e rātou te tu atu i ngā pāmahana teitei me te kore e tino heke te kounga, ā, he mea pai mō ngā tono i roto i ngā taiao ahumahi uaua.
Ko te rīpene kore-ahua, i tētahi atu ringa, he rauemi kore-kiriata me te hanganga ngota koretake. He rerekē ki ngā rīpene nanokiriata,rīpene kore āhuaskāore he rohe kōpaka e taea te tautuhi, engari he rite tonu te whakaritenga ngota. Mā tēnei hanganga ahurei ka puta he āhuatanga aukume ngohengohe pai rawa atu mō ngā rīpene kore āhua, pērā i te iti o te kaha whakapūmau, te nui o te aukumetanga matotoru, me te iti o te ngaronga matua.
He whānui te whakamahinga o te rīpene kore āhua i roto i te hanga i ngā whakawhiti hiko-teitei, ngā pūoko aukume, me ngā parenga whakararuraru hikohiko (EMI). Nā te iti o te ngaronga matua, he tino whai hua ngā rīpene kore āhua ki te huri i te pūngao hiko ki te pūngao aukume, ā, he pai mō ngā tono mana auau-teitei. Nā te iti o te kaha ātete o ngā rīpene kore āhua ka taea te ngāwari o te aukume me te tango aukume, ā, ka whakaitihia ngā ngaronga pūngao i te wā e whakamahia ana.
Ko tētahi o ngā rerekētanga nui i waenga i ngā rīpene nanocrystalline me ngā rīpene amorphous kei roto i tā rātou tukanga hanga. Ka hangaia ngā rīpene nanocrystalline mā te whakapakeketanga tere o te koranu rewa, ā, muri iho ka whakamahanahia kia puta ai te hanganga tioata e hiahiatia ana. I tētahi atu taha, ka hangaia ngā rīpene amorphous mā te whakamatao tere i te koranu rewa i ngā tere miriona nekehanga ia hekona hei ārai i te hanganga o ngā kirikiri.
He motuhake ngā rīpene nanocrystalline me ngā rīpene amorphous i te mākete, e whakatutuki ana i ngā hiahia ahumahi rerekē. Ko te whiriwhiri i waenga i ēnei rauemi e whakawhirinaki ana ki ngā whakaritenga motuhake o te tono e pā ana ki te mahi aukume, te pumau pāmahana, te ngaronga matua, me te whai huatanga utu. Ko ngā āhuatanga ā-roto o ngā rīpene nanocrystalline me ngā rīpene amorphous e hanga ana i a rātou hei wāhanga nui i roto i ngā hikohiko mana, ngā pūnaha pūngao whakahou, ngā waka hiko, me ngā hangarau hou.
Hei whakamutunga, he rerekē ngā painga o te rīpene nanocrystalline me te rīpene amorphous i roto i ngā tono ahumahi rerekē. Ka whakaratohia e ngā rīpene nanocrystalline te urunga aukume me te pumau wera, he mea pai mō te whakamahi i roto i ngā whakawhiti me ngā matua aukume. I tetahi atu ringa, he tino pai ngā āhuatanga aukume ngohengohe o ngā rīpene amorphous, ā, he iti te ngaronga matua, he mea pai mō ngā tono i roto i ngā whakawhiti pūngao-teitei me ngā parepare EMI. Mā te mārama ki ngā rerekētanga i waenga i ngā rīpene nanocrystalline me te amorphous ka taea e ngā kaihanga me ngā kaihanga te whiriwhiri i te rauemi tino tika mō ā rātou hiahia, kia pai ai te mahi me te whai hua o ā rātou hua.
