Mataira sefa yemhepo
Vatsvakurudzi vepaYunivhesiti yeKalifornia, Riverside vakagadzira matanda edenga avanoti anogona kukanganisa kemikari yakaenzana yenitrogen oxides inokuvadza mumhepo mukati megore sezvo avhareji yemotokari inotyaira kupfuura 17 panguva. makiromita. Zvinoenderana nekumwe fungidziro, miriyoni imwe matenga akafukidzwa nematairi akadaro anobvisa mamirioni mazana manomwe ematani emaokisi aya kubva mumhepo pazuva.
Chinokosha kumatenga echishamiso ndeyekusanganiswa kwetitanium dioxide. Vadzidzi vakauya nechigadzirwa ichi vakangovhara matiles emazuva ose, anotengwa muchitoro nawo. Kunyanya, vakaafukidza neakasiyana akaturikidzana echinhu ichi, achivayedza mu "muchadenga mukamuri" yakagadzirwa nematanda, Teflon uye PVC pombi. Vakapomba zvinhu zvinokuvadza zvenitrogen mukati uye vakavhenekera matiles nemwaranzi yeultraviolet, iyo yakaita kuti titanium dioxide ishande.
Mumasampuli akasiyana-siyana, iyo reactive coating yakabviswa kubva pa87 kusvika 97 muzana. zvinhu zvinokuvadza. Sezvineiwo, ukobvu hwedenga rine titanium layer haina kuita misiyano yakawanda pakushanda kwekushanda. Zvisinei, chokwadi ichi chingave chakakosha pamaonero ehupfumi, sezvo matinji akatetepa etitanium dioxide anogona kushanda. Vagadziri parizvino vari kufunga nezve mukana we "kusvibisa" nechinhu ichi zvese zvivakwa, kusanganisira madziro uye zvimwe zvekuvaka.
