Ko te kaha utu o tētahiPūhiko hiko lithium-ion tānga-3D, e toru ngā wā te teitei ake i tērā o tētahi hikohiko i hangaia i ngā tikanga tuku iho. Ka whakarārangihia e te tikanga tā-3D ngā nanoflakes graphite i roto i te rauemi hei whakapai ake i te rere o ngā ion lithium ki roto, ki waho hoki i te hikohiko (i pūrongohia ngā rangahau i te hui ACS Spring 2022).

Whiwhinga: Soyeon Park He anode pākahiko tā-3D

Te pikinga ake o te mahi awhākōkī hou i hangaiae whakaiti ana i te polyethylene terephthalate (PET) ki te whakataurite ki ngā PETases o mua. E 51 ngā tauira PET rerekē i wahia e te whākōkī i roto i ngā wā mai i ngā hāora ki ngā wiki (Taiao2022, DOI:10.1038/s41586-022-04599-z).

Te whai huatanga o tētahipūtau rā perovskitei pūrongohia i te tau 2022, e whakatakoto ana i te rekoata mō ngā photovoltaics kiriata angiangi ngāwari. Ko te pai o te pūtau tandem ki te huri i te hihi o te rā ki te hiko e hinga ana i te kaipupuri rekoata o mua mā te 3 ōrau, ā, ka taea te tu atu ki te 10,000 piko me te kore e ngaro te mahi (Pūngao ā-Motu2022, DOI:10.1038/s41560-022-01045-2).

Ko te tere o tetaputapu tātaritanga hikoka hopu i te hauhā waro ki te whakataurite ki ngā pūnaha hopu waro o nāianei. I tatauhia e ngā kairangahau ko te utu mō tētahi pūnaha tauine nui e taea ai te hopu i te 1,000 tāne mita o te CO2 ia hāora he $145, he iti iho i te whāinga utu a te Tari Pūngao o te $200 ia tāne mita mō ngā hangarau tango waro (Pūngao Taiao. Pūtaiao.2022, DOI:10.1039/d1ee03018c).

E ai ki tētahi pūrongo, e hia ngā tau ki muri i tīmata ai te mahi tektonika o te whenuatātaritanga isotopic o ngā tioata zirconi hangaia i taua wā. Ko ngā tioata, i kohia mai i te moenga onepū i Āwherika ki te Tonga, e whakaatu ana i ngā tohu e rite ana ki ngā mea i hangaia i roto i ngā rohe whakaheke, engari kāore ngā tioata tawhito (AGU Adv.2022, DOI:10.1029/2021AV000520).

Te ōrau o te hihi o te rā e whakaatahia ana e tepeita mā rawakei roto ngā nanoplatelets boron nitride hexagonal. Ka taea e te paninga peita matotoru 150 µm te whakamatao i te mata mā te 5–6 °C i te rā tika, ā, ka āwhina pea ki te whakaiti i te mana e hiahiatia ana hei pupuri i te whakamatao o ngā waka rererangi me ngā motuka (Māngai Pūtau. Pūtaiao Taiao.2022, DOI:10.1016/j.xcrp.2022.101058).
