Ngā mihi nui ki a koe mō tō rēhitatanga ki Physical World. Mēnā kei te hiahia koe ki te whakarerekē i ō taipitopito i tētahi wā, tēnā tirohia taku pūkete.
He tere ake te rere o te honi me ētahi atu wai matotoru i te wai i roto i ngā kapitirei kua pania motuhaketia. Nā Maja Vuckovac me ōna hoa mahi i Te Whare Wānanga o Aalto i Finland te kitenga miharo, ā, i whakaatu anō hoki rātou ko tēnei pānga rerekē i ahu mai i te pehi i te rere o roto i roto i ngā pata matotoru ake. He rerekē tika ā rātou hua i ngā tauira ariā o nāianei mō te rere o ngā wai i roto i ngā kapitirei tino wai-kore.
Ko te mara o te microfluidics e pā ana ki te whakahaere i te rere o ngā wai i roto i ngā rohe pūmau o ngā capillaries—ko te tikanga he mea hanga mō ngā taputapu mō ngā tono hauora. Ko ngā wai matotoru iti te mea pai mō ngā microfluidics nā te mea ka tere te rere me te kore e uaua. Ka taea te whakamahi i ngā wai matotoru ake mā te akiaki i a rātou ki ngā pēhanga teitei ake, engari ka whakanui ake tēnei i te ahotea miihini i roto i ngā hanganga capillary ngawari — ka arahi pea ki te rahunga.
Heoi anō, ka taea te whakateretere i te rere mā te whakamahi i tētahi paninga wai-kore e mau ana i ngā hanganga moroiti me ngā hanganga nano e mau ana i ngā urunga hau. Ka whakaitihia e ēnei urunga te horahanga pa i waenga i te wai me te mata, ka whakaitihia te waku – ka piki ake te rere mā te 65%. Heoi, e ai ki te ariā o nāianei, ka heke tonu ēnei tere rere i te pikinga o te matotoru.
I whakamātauhia tēnei ariā e te tīma a Vuckovac mā te titiro ki ngā pata o ngā matotoru rerekē i te wā e kumea ana e te kaha ā-papa mai i ngā kapiti poutū me ngā paninga o roto tino wai-kore. I a rātou e haere ana i te tere pumau, ka pēhia e ngā pata te hau i raro i a rātou, ka hangaia he pikinga pēhanga e rite ana ki tērā i roto i te piston.
Ahakoa i whakaatuhia e ngā pata wai te whanaungatanga whakahuri i waenganui i te matotoru me te tere rere i roto i ngā ngongo tuwhera, i te wā i hiritia ai tētahi, e rua rānei ngā pito, ka tino hurihia ngā ture. I tino kitea te pānga me ngā pata glycerol—ahakoa e 3 ngā whakarea o te matotoru atu i te wai, i rere atu i te 10 ngā wā tere atu i te wai.
Hei hura i te ahupūngao o tēnei pānga, i whakaurua e te tīma a Vuckovac ngā matūriki whai tohu ki roto i ngā pata. Nā te nekehanga o ngā matūriki i roto i te wā i whakaatu i te rere tere o roto i roto i te pata iti ake te matotoru. Mā ēnei rere ka uru te wai ki roto i ngā hanganga moroiti me te nano-tauine i roto i te paninga. Ka whakaitihia e tēnei te matotoru o te urunga hau, ka ārai i te hau pēhanga i raro i te pata kia kaua e pēhi kia taurite ai te pikinga pēhanga. He rerekē, kāore he rere o roto o te glycerin e kitea ana, ka aukati i tōna urunga ki roto i te paninga. Ka hua ake he urunga hau matotoru ake, ka māmā ake te neke o te hau i raro i te maturuturu ki tetahi taha.
Mā te whakamahi i ā rātou kitenga, i whakawhanakehia e te tīma tētahi tauira waiora hou e pai ake ai te matapae i te nekehanga o ngā pata wai mā roto i ngā uaua toto me ngā paninga waiora rerekē. Mā te mahi tonu, ka ārahi pea ā rātou kitenga ki ngā huarahi hou hei hanga i ngā taputapu waiora iti e kaha ana ki te whakahaere i ngā matū me ngā rongoā uaua.
Ko Physics World tētahi wāhanga nui o te kaupapa a IOP Publishing ki te whakapuaki i ngā rangahau me ngā mahi auaha o te ao ki te hunga whānui. Ko te pae tukutuku nei tētahi wāhanga o te kohinga Physics World, e whakarato ana i tētahi kohinga ratonga mōhiohio ipurangi, matihiko me te tā ki te hapori pūtaiao o te ao.
