Tekinoroji yekuona zvinhu nenzira yekuchenjera ichabatsira varimi kushandisa fetereza zvinobudirira uye kuderedza kukuvara kwezvakatipoteredza.
Tekinoroji iyi, inotsanangurwa mumagazini yeNatural Foods, inogona kubatsira varimi kusarudza nguva yakanakisa yekuisa fetereza pazvirimwa uye huwandu hwefetereza hunodiwa, vachifunga nezvezvinhu zvakaita semamiriro ekunze nemamiriro evhu. Izvi zvichaderedza kudzvanywa kwevhu zvakanyanya uye zvinokuvadza nharaunda, izvo zvinoburitsa gasi rinopisa pasi pevhu (nitrous oxide) uye zvinosvibisa ivhu nenzira dzemvura.
Nhasi uno, kuisirwa fetereza yakawandisa kwaita kuti 12% yevhu raimborimwa pasi rose risashandiswe, uye kushandiswa kwefetereza yenitrogen kwakawedzera ne600% mumakore makumi mashanu apfuura.
Zvisinei, zvakaoma kuti varimi vezvirimwa vagadzirise mashandisirwo avo emafetiraiza nemazvo: yakawanda uye inogona kukanganisa nharaunda uye kushandisa mari shoma uye inogona kuderedza goho;
Vatsvagiri ve tekinoroji itsva iyi vanoti inogona kubatsira nharaunda nevagadziri.
Sensor iyi, inonzi paper-based chemically functionalized electrical gas sensor (chemPEGS), inoyera huwandu hweammonium muvhu, chinhu chinoshandurwa kuita nitrite ne nitrate nemabhakitiriya evhu. Inoshandisa rudzi rwehungwaru hwekugadzira hunonzi machine learning, ichibatanidza nedata remamiriro ekunze, nguva kubva pakashandiswa fetereza, kuyerwa kwepH yevhu uye conductivity. Inoshandisa data iri kufanotaura huwandu hwenitrogen muvhu izvozvi uye huwandu hwenitrogen mumazuva gumi nemaviri anotevera kufanotaura nguva yakanakisa yekuisa fetereza.
Chidzidzo ichi chinoratidza kuti mhinduro iyi itsva inodhura zvishoma inogona kubatsira sei varimi kuti vawane mabhenefiti mashoma kubva mufetereza shoma, kunyanya kune zvirimwa zvinoda fetereza yakawanda zvakaita segorosi. Tekinoroji iyi inogona kuderedza panguva imwe chete mari yemugadziri uye kukuvara kwezvakatipoteredza kubva kufetereza ine nitrogen, iyo inonyanya kushandiswa nefetereza.
Muongorori mukuru Dr Max Greer, wekuDhipatimendi reBioengineering paImperial College London akati: "Dambudziko rekuwedzera fetereza, kubva pamaonero ezvakatipoteredza nehupfumi, harigone kutaurwa zvakanyanya. Kubudirira uye mari inoenderana nayo iri kudzikira gore negore. gore rino, uye vagadziri parizvino havana maturusi anodiwa kugadzirisa dambudziko iri.
"Tekinoroji yedu inogona kubatsira kugadzirisa dambudziko iri nekubatsira varimi kunzwisisa huwandu hweammonia nenitrate huri muvhu uye kufanotaura huwandu hwemangwana zvichienderana nemamiriro ekunze. Izvi zvinovabvumira kugadzirisa mashandisirwo avo efetireza zvichienderana nezvinodiwa nevhu ravo nezvirimwa zvavo."
Fetereza yenitrogen yakawandisa inoburitsa nitrous oxide mumhepo, gasi rinopisa pasi pevhu rine simba rakapetwa mazana matatu kupfuura carbon dioxide uye rinokonzera dambudziko remamiriro ekunze. Fetereza yakawandisa inogonawo kusukurudzwa nemvura inonaya ichienda mumigero yemvura, zvichibvisa okisijeni kubva mumvura, zvichikonzera maruva ealgae uye kuderedza kusiyana-siyana kwezvinhu zvipenyu.
Zvisinei, kugadzirisa mazinga efetiraiza nemazvo kuti aenderane nezvinodiwa nevhu nezvirimwa kuchiri dambudziko. Kuedza hakuwanzoitiki, uye nzira dziripo dzekuyera nitrogen yevhu dzinosanganisira kutumira sampuro dzevhu kurabhoritari—nzira yakareba uye inodhura iyo mhedzisiro yayo isingashandiswi zvakanyanya panguva yainosvika varimi.
Dr Firat Guder, munyori mukuru uye muongorori mukuru muDhipatimendi reEngineering reImperial, vakati: "Chikafu chedu chizhinji chinobva muvhu - ivhu risingadzokororeki uye kana tikasachidzivirira ticharasikirwa naro. Zvakare, pamwe chete nekusvibiswa kweNitrogen kubva mukurima zvinogadzira dambudziko guru pasi rose ratinotarisira kubatsira kugadzirisa kuburikidza nekurima nemazvo, izvo zvatinotarisira kuti zvichabatsira kuderedza kupfumisa kwemafuta ukuwo zvichiwedzera goho rezvirimwa uye purofiti yevarimi."
