Pepala laulere la inki kuti lilowe m'malo mwa pepala labwinobwino

A nzeru zamakono zingathandize kuthana ndi mavuto omwe akuchulukirachulukira m'chilengedwe komanso kukhazikika kwazinthu. Pepala, lopangidwa ku University of California, Riverside, limatha kulembedwa ndikufufutidwa kangapo.

Pepalali, ngati galasi kapena filimu yapulasitiki, limagwiritsa ntchito utoto wa redox. Utoto umapanga "gawo lojambula" la pepala, zithunzi ndi zolemba, ndipo kuwala kwa UV kumatulutsa utoto kupatula utoto womwe umapanga zolemba kapena zithunzi pamapepala. Kuwala kwa UV kumachepetsa utoto kuti ukhale wopanda mtundu kotero kuti zomwe zingawonekere ndi zithunzi kapena zolemba zomwe zimapangidwa. Chilichonse cholembedwa chimakhala kwa masiku atatu.

Chilichonse chimafufutidwa ndi kutentha kwa 115 C, pamene "kutulutsanso oxidation kwa utoto wochepetsedwa kumabwezeretsanso mtundu wakale." Kufufuta kumatha kutha mkati mwa mphindi 10.

Pogwiritsa ntchito njirayi, pepalali likhoza kulembedwa, kufufuta, kenako kulembedwanso maulendo oposa 20 “popanda kutayika kwakukulu kosiyana kapena kusamvana.” Pepala likhoza kukhala lamitundu itatu: buluu, wofiira, ndi wobiriwira.

Malinga ndi Yadong Yin, pulofesa wa chemistry amene anathandiza kutsogolera kafukufuku wa nkhaniyi, “pepala lokhoza kulembedwanso silifuna inki zowonjezera kuti lisindikizidwe, kupangitsa kuti likhale lothandiza pazachuma komanso chilengedwe. Izi zikuyimira chidwi pamapepala anthawi zonse pokwaniritsa zofunikira zomwe zikuchulukirachulukira zapadziko lonse lapansi pakukhazikika komanso kuteteza chilengedwe. ” Kusintha kumeneku kungathe kuchepetsa kugwiritsa ntchito mapepala, limodzi mwa malonjezo a m'badwo watsopano wa digito.

Malinga ndi WWF, mapepala akupangidwa pafupifupi matani 400 miliyoni (matani 362 miliyoni) pachaka ndipo akukwera.
