Whakaahuatanga me ngā Āhuatanga

Whakaahuatanga: Ka whakamahia e WNX te hangarau whakaputa aunoa matatau, ā, ka whakamahia ngā rauemi mata kounga teitei hei whakaputa i te kounga teitei.Waikura Serium.

Ngā Āhuatanga Matua:

Teitei o te Parakore:Waikura Serium kāore he poke o ngā huānga whenua onge (pērā i te rino, te konupūmā, te konutai), ā, he iti noa te nui o te poke.

Te Wairewatanga Pai:Waikura Serium ka tere te memeha i roto i te wai me ngā waikawa kaha.

Te Pūmautanga: Te whakahaere pakari o ngā puranga i roto i te whakaputanga oWaikura Serium e whakarite ana i te kounga pumau mō te whakaputanga ahumahi nui.

Te whakakanapa tika: Ko te waikura cerium te rauemi whakakanapa karāhe tino whai hua, e whakamahia whānuitia ana i roto i te tukatuka pai o ngā arotahi kāmera, ngā arotahi mōhiti, ngā taputapu whatu, ngā papa haurua-ira (te whakakanapa matū me te miihini CMP), me ētahi atu. Ka taea e ia te whakatutuki tere i tētahi mata tino maeneene mā roto i ngā mahi matū me ngā mahi miihini.

Te Whakaoho Taiao: I roto i te purenga o te hau putanga waka (te kaitahuri whakaterenga-toru-ara), ko te waikura cerium te wāhanga matua, e penapena ana, e tuku ana hoki i te hāora, e āwhina ana i te hurihanga o te hauota waro (CO), ngā hauwaiwaro (HC), me ngā waikura hauota (NOx) hei hauota waro kinokore, te hauota, me te wai. E whakamahia ana hoki i roto i te maimoatanga hau putanga ahumahi me ngā tauhohenga nekehanga wai-hau, me ētahi atu.

Ahumahi Karāhe: I roto i te tukanga hanga karāhe, he maha ngā mahi a te cerium oxide: (1) Kaihoko whakama: Ka whakakōkī i ngā iona rino matomato takirua i roto i te karāhe hei iona rino takirua māmā ake, kia mārama ake ai te karāhe; (2) Kaihoko whakamārama: Ka tangohia ngā mirumiru mai i te karāhe rewa; (3) Kaihoroi UV: Ka mimiti i ngā hihi ultraviolet, ā, ka whakamahia hei hanga karāhe tiaki rā me ngā matapihi rererangi. Ka taea hoki te whakakotahi me te titanium dioxide hei tae i te karāhe.

Pūngao me te Hikohiko: Nā tōna kawe hiko me te pumau, he rauemi electrolyte nui te cerium oxide mō ngā pūtau wahie waikura totoka (SOFC). I roto i te ao hikohiko, ka whakamahia hei hanga i ngā wāhanga uku hiko pēnei i ngā capacitors me ngā uku piezoelectric.
