Ururka Caafimaadka Adduunka iyo Xarumaha Xakamaynta Cudurrada ee Maraykanka labaduba waxay aqoonsan yihiin in hawada hawada sare ay tahay habka koowaad ee faafitaanka fayraska COVID-19. Aerosols waa qaybo yaryar oo biyo ah ama walxo kale oo hawada ku hadhi kara wakhti dheer, oo yar oo ku filan inay galaan habka neefsashada.
Dadku waxay sii daayaan hawada hawada marka ay neefsanayaan, qufacayaan, hadlaan, qaylinayaan ama heesayaan. Aerosols-yadani waxa kale oo ay ku jiri karaan fayraska haddii ay qabaan COVID-19. Neefsashada xaddi ku filan aerosols ee coronavirus waxay qofka ka dhigi kartaa jirro. Iyada oo looga baahan yahay dadka inay xidhaan maaskaro, hagaajinta hawo-mareenka gudaha iyo nidaamka shaandhaynta hawada, yaraynta soo-gaadhista shakhsi ahaaneed iyo yaraynta tirada guud ee hawo-mareenada deegaanka ayaa ah mudnaanta si loo xakameeyo fiditaanka COVID-19 aerosols.
Cilmi-baarista fayraska cusub ee faafa waa khatar, waana naadir shaybaarrada leh heerarka ugu sarreeya ee badbaadada noolaha. Dhammaan daraasaadka ilaa maanta ee ku saabsan waji-xidhka ama hufnaanta sifaynta inta lagu jiro aafada waxay adeegsadeen agab kale oo loo malaynayo inay ku dayanayaan cabbirka iyo dhaqanka hawada hawada sare ee SARS-CoV-2. Daraasada cusub ayaa taas ku wanaajisay, tijaabinta xalalka cusbada hawada hawada laga saaray iyo hawada ay ku jirto koronafayras ka soo jeeda isla qoyska fayraska keena COVID-19 laakiin kaliya waxa uu ku dhaca jiirka.
Yun Shen iyo saaxiibkii jaamacadda George Washington Danmeng Shuai ayaa abuuray filter nanofiber kaas oo keena danab sare iyada oo loo marayo dhibicda dareeraha polyvinylidene fluoride ilaa dun wareeg ah oo ku saabsan 300 nanometer dhexroor - qiyaastii 167 jeer ka khafiifsan timaha bini'aadamka. Nidaamkani waxa uu abuuray daloolo dhawr mikromitir oo dhexroor ah oogada nanofibers, taasoo ka caawisay inay qabtaan 99.9 boqolkiiba hawada hawada sare ee coronavirus.
Farsamada wax soo saarka, oo loo yaqaan electrospinning, waa kharash-ool ah waxaana loo isticmaali karaa in si ballaaran loo soo saaro filtarrada nanofiber ee qalabka ilaalinta shakhsi ahaaneed iyo hababka sifeynta hawada. Electrospinning waxa kale oo ay ka tagtaa lacag koronto ah oo ku jirta nanofiber-yada, taas oo kor u qaadaysa awoodda ay u leeyihiin in ay qabtaan hawada hawada, iyo porosity-keeda sare waxa ay sahlaysaa in la neefsado iyada oo xidhan filter nanofiber electrospun.
"Tiknoolajiyada elektiroonigga ah waxay fududeyn kartaa naqshadeynta iyo soo saarista maaskaro iyo filtarrada hawada," ayuu yiri Prof. Yun Shen. "Isticmaalka tignoolajiyada elektiroonigga ah si loo horumariyo noocyada cusub ee waji-xidhka iyo filtarrada hawada waxay leedahay waxqabad sifeyn wanaagsan, suurta gal dhaqaale iyo miisaan. Awood u yeelashada baahida waji-xidhka iyo filtarrada hawada ee garoonka waa mid rajo leh."
