Isivamvo serhasi esiphathwayo seXesha lokwenyani lokuFumana iCarbon monoxide

Kwinqaku lakutshanje elipapashwe kwiphephancwadi IiNgxelo zeSayensi, abaphandi baxoxa ngokuphuhliswa kwenkqubo yegesi ephathekayo yokukhangela i-carbon monoxide yexesha langempela. Le nkqubo isungulayo idibanisa izinzwa eziphambili ezinokujongwa ngokulula nge-app ye-smartphone ezinikeleyo. Olu phando lujolise ekuboneleleni ngesisombululo esibambekayo nesisebenzayo sokubeka iliso kumanqanaba eCO kwiindawo ezahlukeneyo.

Uphononongo lwangaphambili luye lwabalaselisa ukubaluleka kwezinzwa ezithembekileyo ze-fuel zokubona iigesi ezinobungozi ezifana ne-carbon monoxide. Ukuhlanganiswa kobuchwephesha banamhlanje, kuquka i-microcontrollers kunye ne-mobile apps, kunokuphucula ukusebenza kunye nokufikeleleka kwezixhobo zokubona amafutha. Ukusetyenziswa kwe-PN heterojunctions kunye nezixhobo ezithile ze-nanowire ezifana ne-CuO / i-foam yethusi (CF) iphucule ngakumbi uvakalelo kunye nokukhetha kwezi zinzwa zamafutha.

I-sensor idibaniswe nokunikezelwa kwamandla kunye nezixhobo zokulinganisa ukuchasana ukulandelela utshintsho ekuchaseni xa kubonakaliswe kwiindawo ezahlukeneyo zepetroli. Isixhobo sonke sasivalelwe kwigumbi lokulawula ukulinganisa imeko yokufumanisa amafutha.

Ukuvavanya ukusebenza ngokubanzi kwesixhobo se-fuel sensor, i-concentrations eyahlukeneyo ye-nitrogen (N2), i-oksijeni (i-O2), kunye ne-carbon monoxide (CO) iigesi zihlolwe. I-fuel concentration isuka kwiingxenye ze-10 kwisigidi ukuya kwi-900 inxalenye yezigidi (ppm) ukuvavanya ukuvakalelwa kunye neempawu zokuphendula zenzwa. Ixesha lokuphendula le-sensor kunye nexesha lokuphilisa lirekhodwa kumaqondo okushisa athile kunye namanqanaba omswakama ukuchonga ukusebenza kwayo phantsi kweemeko ezahlukeneyo zokusingqongileyo.

Ngaphambi kokwenza iimvavanyo ezisesikweni zokuva irhasi, inkqubo yokuva irhasi kufuneka ilandele inkqubo yokulinganisa ukuqinisekisa ukuba imilinganiselo echanekileyo nethembekileyo. Ijika lokulinganisa iveliswa ngokutyhila inzwa kugxininiso lwegesi eyaziwayo kunye nokulungelelanisa utshintsho lokumelana nenqanaba legesi. Impendulo ye-sensor iqinisekiswa ngokuchasene nemigangatho yokubona igesi esekelwe ukuqinisekisa ukuchaneka kwayo kunye nokuhambelana ekufumaneni i-carbon monoxide.

Sinokubonelela ngeenzwa ezilinganisa iindidi ngeendidi zeegesi, ngolu hlobo lulandelayo
