I-Smart sensor technology ezosiza abalimi ukuthi basebenzise umanyolo ngendlela egculisayo futhi banciphise nokonakala kwendawo.
Lobu buchwepheshe, obuchazwe kumagazini i-Natural Foods, bungasiza abakhiqizi babone isikhathi esingcono kakhulu sokusebenzisa umanyolo ezitshalweni kanye nenani likamanyolo odingekayo, kucatshangelwa izici ezinjengesimo sezulu nesimo senhlabathi. Lokhu kuzonciphisa ukuvundisa ngokweqile kwenhlabathi okumba eqolo nokulimaza imvelo, okukhulula igesi ebamba ukushisa nitrous oxide futhi kungcolise inhlabathi nemigudu yamanzi.
Namuhla, ukuvundisa ngokweqile sekwenze u-12% womhlaba olimekayo ungasebenziseki, futhi ukusetshenziswa komanyolo wenitrogen kukhuphuke ngo-600% kule minyaka engu-50 edlule.
Nokho, kunzima kubakhiqizi bezitshalo ukulawula ngokunembile ukusetshenziswa kwabo kukamanyolo: kakhulu futhi basengozini yokulimaza imvelo nokusebenzisa imali encane kakhulu futhi babeka engcupheni yesivuno esincane;
Abacwaningi bobuchwepheshe obusha bezinzwa bathi bungazuzisa imvelo nabakhiqizi.
Inzwa, ebizwa nge-paper-based chemically functionalized gas sensor (chemPEGS), ikala inani le-ammonium enhlabathini, inhlanganisela eguqulwa ibe yi-nitrite ne-nitrate ngamabhaktheriya enhlabathini. Isebenzisa uhlobo lobuhlakani bokwenziwa olubizwa ngokuthi ukufunda ngomshini, ukuhlanganisa nedatha ngesimo sezulu, isikhathi kusukela ekufakweni komanyolo, izilinganiso ze-pH yenhlabathi kanye nokuhamba kahle. Isebenzisa le datha ukubikezela inani eliphelele le-nitrogen enhlabathini manje kanye nenani eliphelele le-nitrogen ezinsukwini eziyi-12 esikhathini esizayo ukubikezela isikhathi esingcono kakhulu sokufaka umanyolo.
Ucwaningo lukhombisa ukuthi lesi sixazululo esisha esingabizi kakhulu singasiza kanjani abakhiqizi ukuthi bathole inzuzo enkulu enanini elincane likamanyolo, ikakhulukazi ezitshalweni ezidinga umanyolo onjengokolweni. Lobu buchwepheshe bunganciphisa ngesikhathi esisodwa izindleko zomkhiqizi kanye nokulimala kwemvelo okuvela kumanyolo we-nitrogen, uhlobo lomanyolo olusetshenziswa kakhulu.
Umcwaningi oholayo uDkt Max Greer, ovela eMnyangweni we-Bioengineering e-Imperial College London uthe: “Inkinga yokuvundisa ngokweqile, ngokombono wemvelo nomnotho, angeke yaqiniswa, ukukhiqiza kanye nemali engenayo ehlobene nayo iyehla unyaka nonyaka.
“Ubuchwepheshe bethu bungasiza ekuxazululeni le nkinga ngokusiza abalimi baqonde amazinga amanje e-ammonia ne-nitrate emhlabathini futhi babikezele amazinga esikhathi esizayo ngokusekelwe esimweni sezulu.
Umanyolo we-nitrogen oweqile ukhiphela i-nitrous oxide emoyeni, igesi ebamba ukushisa ephindwe izikhathi ezingama-300 kune-carbon dioxide futhi enomthelela enkingeni yesimo sezulu. Umanyolo oweqile ungakhukhulwa namanzi emvula angene emanzini, kuncishe ukuphila kwasemanzini umoya-mpilo, kubangele ukuqhakaza kwe-algae futhi kunciphise izinhlobonhlobo zezinto eziphilayo.
Nokho, ukulungisa kahle amazinga kamanyolo ukuze ahambisane nezidingo zenhlabathi kanye nezitshalo kuseyinselelo. Ukuhlola kuyivelakancane, futhi izindlela zamanje zokukala i-nitrogen yenhlabathi zihilela ukuthumela amasampula enhlabathi elabhorethri—inqubo ende nemba eqolo imiphumela yayo isuke isetshenziswa kancane lapho ifinyelela abalimi.
UDkt Firat Guder, umbhali omkhulu kanye nomcwaningi oholayo eMnyangweni we-Imperial of Bioengineering, uthe: “Ukudla kwethu okuningi kuvela emhlabathini – kuwumthombo ongavuseleleki futhi uma singawuvikeli uzolahlekelwa yikho.” Futhi, kuhlangene nokungcoliswa kweNitrogen okuvela kwezolimo kudala isiphithiphithi sokwandisa umhlaba esithemba ukuthi sizosiza ukuxazulula ngokukhula kwezitshalo ngokunemba kanye nethemba lokuthi isivuno sizosiza ekukhuleni kwezitshalo ngokunemba, futhi sizosiza ekunciphiseni ukulima kwezitshalo ngokunemba. inzuzo.”
