I-Antimicrobial Polyurea Coatings With Rare Earth-Doped

I-Antimicrobial Polyurea Coatings With Rare Earth-Doped Nano-Zinc Oxide Particles

umthombo:AZO MATERIALSUbhubhane lwe-Covid-19 lukhombise isidingo esiphuthumayo sezingubo ezilwa namagciwane kanye nezindawo ezilwa namagciwane ezindaweni zomphakathi nasezindaweni zokunakekelwa kwempilo. Ucwaningo lwakamuva olwanyatheliswa ngo-Okthoba 2021 kujenali iMicrobial Biotechnology lubonise ukulungiswa kwe-nano-Zinc oxide esheshayo ye-polyurea coatings efuna ukuxazulula le nkinga. ukudluliswa. Isidingo esiphuthumayo samakhemikhali asheshayo, asebenzayo, futhi angenabo ubuthi kanye nemithi elwa namagciwane kanye ne-antiviral surface coatings sigqugquzele ucwaningo olusha emkhakheni we-biotechnology, i-industrial chemistry, kanye nesayensi yezinto zokwakha.Izimbobo zangaphezulu ezilwa namagciwane kanye ne-antimicrobial zinganciphisa ingozi yokudluliselwa kwegciwane. futhi abulale ama-biostructures nama-microorganisms lapho uthintana. Zivimbela ukukhula kwama-microorganisms ngokuphazanyiswa kwe-membrane yeselula. Ziphinde zithuthukise izindawo ezingaphezulu, ezinjengokumelana nokugqwala nokuqina.Ngokwe-European Center for Disease Control and Prevention, abantu abayizigidi ezingu-4 (cishe abantu baseNew Mexico abaphindwe kabili) emhlabeni wonke ngonyaka bathola ukutheleleka okuhlobene nokunakekelwa kwezempilo. Lokhu kuholela ekufeni kwabantu ababalelwa ku-37,000 emhlabeni wonke, futhi isimo sibi kakhulu emazweni asathuthuka lapho abantu bengase bangakwazi ukufinyelela ingqalasizinda efanele yokukhucululwa kwendle kanye nenhlanzeko yezempilo. Emazweni aseNtshonalanga, ama-HCAI ayimbangela yesithupha enkulu yokufa.Yonke into isengozini yokungcoliswa amagciwane namagciwane - ukudla, izinto zokusebenza, izindawo ezingaphezulu nezindonga, nezindwangu kuyizibonelo ezimbalwa nje. Ngisho nezinhlelo ezijwayelekile zokukhucululwa kwendle kungenzeka zingabulali wonke amagciwane akhona endaweni, ngakho-ke kunesidingo esicindezelayo sokwenza izinto zokumboza ezingewona ubuthi ezivimbela ukukhula kwe-microbial ukuthi kwenzeke. ezindaweni zensimbi engagqwali nepulasitiki ezithintwa njalo kuze kufike emahoreni angama-72, okubonisa isidingo esiphuthumayo sezingubo ezingaphezulu ezinezakhiwo ezilwa namagciwane. Izindawo ezilwa namagciwane zisetshenziswe ezilungiselelweni zokunakekelwa kwezempilo isikhathi esingaphezu kweminyaka eyishumi, zisetshenziselwa ukulawula ukuqubuka kwe-MRSA.I-Zinc Oxide - I-Antimicrobial Chemical CompoundZinc oxide (ZnO) ehlotshaniswa kakhulu ne-antimicrobial enamandla. Ukusetshenziswa kwe-ZnO kuhlolisiswe ngokujulile eminyakeni yamuva nje njengesithako esisebenzayo kumakhemikhali amaningi e-antimicrobial kanye namagciwane. Ucwaningo oluningi lobuthi luthole ukuthi i-ZnO cishe ayinabo ubuthi kubantu nasezilwaneni kodwa iphumelela kakhulu ekuphazamiseni izimvilophu zamangqamuzana amagciwane.Izindlela zokubulala ama-microorganisms we-Zinc oxide zingabalelwa ezintweni ezimbalwa. I-Zn2+ ions ikhishwa ngokuhlakazwa ingxenye yezinhlayiya ze-Zinc Oxide eziphazamisa umsebenzi owengeziwe wokulwa namagciwane ngisho nakwamanye amagciwane akhona, kanye nokuxhumana okuqondile nezindonga zamangqamuzana nokukhululwa kwezinhlobo zomoya-mpilo osebenzayo.Umsebenzi we-Zinc Oxide antimicrobial uxhunyaniswa nobukhulu bezinhlayiyana nokugxila. : izinhlayiya ezincane kanye nezixazululo zokugxila okuphezulu kwe-Zinc nanoparticles ziye zanda umsebenzi we-antimicrobial. Ama-nanoparticles e-Zinc Oxide amancane ngosayizi angena kalula kulwelwesi lwamaseli amancane ngenxa yendawo yawo enkulu ehlangene. Ucwaningo oluningi, ikakhulukazi lwe-Sars-CoV-2 muva nje, luye lwacacisa isenzo esisebenza ngendlela efanayo ngokumelene namagciwane. Ukusebenzisa i-RE-Doped Nano-Zinc Oxide kanye ne-Polyurea Coatings Ukwakha Indawo Enezakhiwo Ezinamandla Ezilwa NamagciwaneIthimba lika-Li, Liu, Yao, kanye neNarasimalu lihlongoze. indlela yokulungisa ngokushesha izimbotshana ze-antimicrobial polyurea ngokwethula i-nano-Zinc ene-rare-doped-doped Izinhlayiya ze-oksidi ezidalwe ngokuxuba ama-nanoparticles nomhlaba ongavamile ku-nitric acid.Ama-nanoparticles e-ZnO afakwe i-Cerium (Ce), i-Praseodymium (Pr), i-Lanthanum (LA), ne-Gadolinium (Gd.) Izinhlayiya ze-Lanthanum-doped nano-Zinc Oxide zazi itholwe iphumelela ngo-85% ngokumelene ne-P. aeruginosa kanye nezinhlobo zebhaktheriya ze-E. Coli. ama-nanoparticles nawo ahlala esebenza ngama-83% ekubulaleni amagciwane, ngisho nangemva kwemizuzu engama-25 yokuchayeka ekukhanyeni kwe-UV. Izinhlayiya ezihlanganisiwe ze-nano-Zinc Oxide ezihlolwe ocwaningweni zingabonisa impendulo yokukhanya kwe-UV ethuthukisiwe kanye nokusabela okushisayo ekushintsheni kwezinga lokushisa. Ama-Bioassays kanye ne-surface characterization iphinde yanikeza ubufakazi bokuthi izindawo ezingaphezulu zigcina imisebenzi yazo yokulwa namagciwane ngemva kokusetshenziswa okuphindaphindiwe.Izingqimba ze-Polyurea nazo zinokuhlala isikhathi eside okunengozi encane yokuxebuka. Ukuqina kwezindawo ezingaphezulu okuhambisana nemisebenzi elwa namagciwane kanye nokusabela kwemvelo kwezinhlayiya ze-nano-ZnO kunikeza ukuthuthukiswa kwamandla azo okusebenza ezimweni ezihlukahlukene nezimboni. ukudluliswa kwama-HPAI ezindaweni zokunakekelwa kwempilo. Kukhona futhi amathuba okuthi zisetshenziswe embonini yokudla ukuze zinikeze ukupakishwa kwe-antimicrobial kanye nemicu, ukuthuthukisa ikhwalithi nempilo yeshalofu yokudla esikhathini esizayo. Nakuba lolu cwaningo lusaqala, akungabazeki ukuthi maduze luzophuma elabhorethri lungene emkhakheni wezohwebo.
