Ukadaulo wotsatira wa sensa ya gasi womwe ukuperekedwa kuti ugwiritsidwe ntchito m'malo a mafakitale ndi azachipatala

Mu pepala lofalitsidwa mu Journal of Chemical Engineering, asayansi apeza kuti mpweya woipa monga nayitrogeni dioxide ndi wofala kwambiri m'mafakitale.

Kupuma mpweya wa nayitrogeni dioxide kungayambitse matenda oopsa a kupuma monga mphumu ndi bronchitis, zomwe zimaika pachiwopsezo thanzi la ogwira ntchito m'mafakitale. Chifukwa chake, kuyang'aniridwa nthawi zonse ndikofunikira kuti malo ogwirira ntchito akhale otetezeka.
Pofuna kuthana ndi vutoli, mitundu yambiri ya masensa osankha a gasi yapangidwa pogwiritsa ntchito zinthu zosiyanasiyana zachilengedwe ndi zosapangidwa. Zina mwa masensawa, monga masensa a gasi chromatography kapena masensa a gasi a electrochemical, ndi apamwamba kwambiri koma okwera mtengo komanso olemera. Kumbali ina, masensa okhazikika pa semiconductor ndi resistive ndi njira ina yabwino, ndipo masensa a gasi okhala ndi semiconductor (OSC) amapereka njira yotsika mtengo komanso yosinthasintha. Komabe, masensawa a gasi akadali ndi mavuto ena ogwira ntchito, kuphatikizapo kuchepa kwa mphamvu komanso kusakhazikika bwino pakugwiritsa ntchito masensa.
Timapereka masensa osiyanasiyana apamwamba kwambiri m'malo osiyanasiyana oti musankhe!
