Kwinqaku lakutshanje elipapashwe kwijenali iScientific Reports, abaphandi baxoxa ngophuhliso lwenkqubo ye-sensor yegesi ephathekayo yokufumanisa i-carbon monoxide ngexesha langempela. Le nkqubo intsha idibanisa ii-sensor eziphambili ezinokujongwa ngokulula nge-app yefowuni ezinikeleyo. Olu phando lujolise ekuboneleleni ngesisombululo esincinci nesisebenzayo sokujonga amanqanaba e-CO kwiindawo ezahlukeneyo.
Izifundo zangaphambili zigxininise ukubaluleka kwee-fuel sensors ezinokuthenjwa ekufumaneni iigesi ezinobungozi ezifana ne-carbon monoxide. Ukuhlanganiswa kwezobuchwepheshe banamhlanje, kuquka ii-microcontrollers kunye nee-apps zeselula, kunokuphucula ukusebenza kunye nokufikeleleka kwezixhobo zokuva i-fuel. Ukusetyenziswa kwe-PN heterojunctions kunye nezixhobo ezithile ze-nanowire ezifana ne-CuO/copper foam (CF) kuphucule ngakumbi ubuntununtunu kunye nokukhetha kwezi sensors ze-fuel.
Isixhobo sokuvavanya amandla sasiqhagamshelwe kwizixhobo zokulinganisa umbane kunye nokumelana ukuze kulandelelwe utshintsho ekumelaneni xa kuvezwa kumanqanaba ahlukeneyo epetroli. Isixhobo sonke sasivalelwe kwigumbi lolawulo ukuze silingise imeko yokwenyani yokubhaqwa kwepetroli.
Ukuvavanya ukusebenza kwesixhobo se-fuel sensor, kuhlolwe amazinga ahlukeneyo e-nitrogen (N2), i-oxygen (O2), kunye neegesi ze-carbon monoxide (CO). Uxinzelelo lwamafutha lwaluqala kwi-10 parts per million ukuya kwi-900 parts per million (ppm) ukuvavanya iimpawu zobuntununtunu kunye nempendulo ye-sensor. Ixesha lokuphendula kwe-sensor kunye nexesha lokuphiliswa kwayo zirekhodwa kumaqondo athile obushushu kunye namanqanaba okufuma ukuze kuchongwe ukusebenza kwayo phantsi kweemeko ezahlukeneyo zendalo.
Ngaphambi kokuba kwenziwe uvavanyo olusemthethweni lokuva igesi, inkqubo yokuva igesi kufuneka idlule kwinkqubo yokulinganisa ukuqinisekisa umlinganiselo ochanekileyo nothembekileyo. Ijika lokulinganisa lenziwa ngokubeka i-sensor kumanqanaba egesi aziwayo kunye nokudibanisa utshintsho lokuxhathisa nenqanaba legesi. Impendulo ye-sensor iqinisekiswa ngokuchasene nemigangatho yokuva igesi emiselweyo ukuqinisekisa ukuchaneka kwayo kunye nokuhambelana kwayo ekufumaneni i-carbon monoxide.
Singabonelela ngee-sensors ezilinganisa iintlobo ngeentlobo zeegesi, ngolu hlobo lulandelayo
