Sensor ya Gasi Yonyamulika Yodziwira Mpweya wa Carbon Monoxide Pa Nthawi Yeniyeni

Mu nkhani yaposachedwa yomwe inafalitsidwa mu magazini ya Scientific Reports, ofufuza akukambirana za chitukuko cha makina oyezera mpweya onyamulika kuti azitha kuzindikira mpweya wa carbon monoxide nthawi yeniyeni. Dongosolo latsopanoli limaphatikiza masensa apamwamba omwe amatha kuyang'aniridwa mosavuta kudzera mu pulogalamu yapadera ya foni yam'manja. Kafukufukuyu cholinga chake ndi kupereka yankho laling'ono komanso lothandiza poyang'anira kuchuluka kwa CO m'malo osiyanasiyana.

Kafukufuku wakale wasonyeza kufunika kwa masensa odalirika amafuta kuti azindikire mpweya woipa monga carbon monoxide. Kuphatikiza matekinoloje amakono, kuphatikizapo ma microcontrollers ndi mapulogalamu am'manja, kungathandize kuti zipangizo zowunikira mafuta zigwire bwino ntchito komanso kuti zizitha kupezeka mosavuta. Kugwiritsa ntchito ma PN heterojunctions ndi zipangizo zinazake monga CuO/copper foam (CF) kunawonjezeranso chidwi ndi kusankha kwa masensa amafuta awa.

Sensayi idalumikizidwa ku zida zamagetsi ndi zoyezera kukana kuti itsatire kusintha kwa kukana ikakumana ndi kuchuluka kwa mafuta osiyanasiyana. Chipangizo chonsecho chidatsekedwa m'chipinda chowongolera kuti chiyerekezere momwe zinthu zenizeni zodziwira mafuta zimachitikira.

Kuti aone momwe chipangizo choyezera mafuta chikuyendera, anafufuza kuchuluka kwa mpweya wa nayitrogeni (N2), mpweya wa okosijeni (O2), ndi mpweya wa carbon monoxide (CO) mosiyanasiyana. Kuchuluka kwa mafuta kunayambira magawo 10 pa miliyoni mpaka magawo 900 pa miliyoni (ppm) kuti aone momwe sensa imamvera komanso momwe imayankhira. Nthawi yoyankhira ya sensa komanso nthawi yochira zimalembedwa pa kutentha ndi chinyezi kuti zizindikire momwe imagwirira ntchito pansi pa mikhalidwe yosiyanasiyana ya chilengedwe.

Musanayambe kuyesa kovomerezeka kozindikira mpweya, makina ozindikira mpweya ayenera kutsatira njira yowunikira kuti atsimikizire kuti miyeso yolondola komanso yodalirika imachitika. Mzere wowongolera mpweya umapangidwa powonetsa sensa ku kuchuluka kwa mpweya komwe kumadziwika ndikugwirizana ndi kusintha kwa kukana ndi kuchuluka kwa mpweya. Yankho la sensa limatsimikiziridwa motsutsana ndi miyezo yodziwika bwino yowunikira mpweya kuti zitsimikizire kulondola kwake komanso kusasinthasintha kwake pozindikira carbon monoxide.

Tikhoza kupereka masensa omwe amayesa mitundu yosiyanasiyana ya mpweya, motere
