ʻO ka mea hoʻohana i hoʻohana ʻia no ka hoʻopau ʻana i nā mea olaola a me nā mea hoʻoweliweli.Puna kiʻi: Northwestern University
Hiki ke hoʻohana ʻia ka mea hoʻohui fiber composite multifunctional MOF i hoʻolālā ʻia ma ke ʻano he lole pale e kūʻē i nā mea olaola a me nā mea hoʻoweliweli.
Hiki ke hoʻohana ʻia nā mea hoʻoheheʻe N-chloro-based multifunctional a me ka hoʻohou i ka zirconium metal organic frame (MOF) ikaika.
Hōʻike ka mea fiber composite i ka hana biocidal wikiwiki e kūʻē i nā bacteria Gram-negative (E. coli) a me Gram-positive bacteria (Staphylococcus aureus), a hiki ke hoʻemi ʻia kēlā me kēia maʻi i 7 logarithms i loko o 5 mau minuke.
Hiki i nā mea hui MOF/fiber i hoʻopiha ʻia me ka chlorine ikaika ke hoʻohaʻahaʻa i ka sinapi sulfur a me kāna analogue kemika 2-chloroethyl ethyl sulfide (CEES) me ka hapalua o ke ola ma lalo o 3 mau minuke.
Ua hoʻomohala kahi hui noiʻi mai Northwestern University i kahi lole composite multifunctional e hiki ke hoʻopau i nā hoʻoweliweli olaola (e like me ka coronavirus hou e hoʻokumu ai i ka COVID-19) a me nā hoʻoweliweli kemika (e like me nā mea i hoʻohana ʻia i ke kaua kemika).
Ma hope o ka hoʻoweliweli ʻia ʻana o ka lole, hiki ke hoʻihoʻi ʻia ka mea i kona ʻano kumu ma o ka hoʻomaʻamaʻa bleaching maʻalahi.
"He mea koʻikoʻi ka loaʻa ʻana o kahi mea hana ʻelua e hiki ai ke hoʻopau i nā mea ʻona a me nā mea ʻawaʻawa i ka manawa like no ka mea he kiʻekiʻe loa ka paʻakikī o ka hoʻohui ʻana i nā mea he nui e hoʻopau i kēia hana," wahi a Omar Farha o ke Kulanui o Northwestern, ʻo ia ka metal-organic framework a i ʻole nā loea MOF. , ʻo ia ke kumu o ka ʻenehana.
He polopeka 'o Farha ma ke Kula 'Oihana a me 'Epekema o Weinberg a me ka mea kākau like o ka ha'awina.He lālā ʻo ia o ka International Institute of Nanotechnology ma Northwestern University.
Hoʻokumu ʻia ka MOF/fiber composites ma ka noiʻi mua ʻana i hana ai ka hui o Farha i kahi nanomaterial hiki ke hoʻopau i nā mea aʻalolo ʻona.Ma o kekahi mau hana liʻiliʻi, hiki i nā mea noiʻi ke hoʻohui pū i nā mea antiviral a me antibacterial i ka mea.
Ua ʻōlelo ʻo Faha ʻo MOF he "ʻauʻau ʻauʻau pololei."Hoʻolālā ʻia nā mea nano-nui me nā lua he nui, hiki ke hoʻopaʻa i ke kinoea, ka mahu a me nā mea ʻē aʻe e like me ka ʻūhā ʻana i ka wai.I loko o ka lole hoʻohui hou, ʻo ka lua o ka MOF he mea hoʻoikaika hiki ke hoʻopau i nā kinikona ʻona, nā maʻi maʻi a me nā maʻi bacteria.Hiki ke hoʻopili maʻalahi i nā nanomaterials porous ma nā fiber textile.
Ua ʻike nā mea noiʻi ua hōʻike ka MOF/fiber composites i ka hana wikiwiki e kūʻē iā SARS-CoV-2, a me Gram-negative bacteria (E. coli) a me Gram-positive bacteria (Staphylococcus aureus).Eia hou, hiki i nā MOF/fiber composites i hoʻopiha ʻia me ka chlorine ikaika hiki ke hoʻohaʻahaʻa koke i ke kinoea sinapi a me kāna mau mea hoʻohālikelike (2-chloroethyl ethyl sulfide, CEES).ʻO nā nanopores o ka mea MOF i uhi ʻia ma ka textile he ākea ākea e ʻae i ka hou a me ka wai e pakele.
Ua hoʻohui ʻo Farha, hiki ke hoʻonui ʻia kēia mea hoʻohui no ka mea e koi wale ana i nā lako hana textile maʻamau i hoʻohana ʻia i ka ʻoihana.Ke hoʻohana pū ʻia me ka mask, hiki i ka mea ke hana i ka manawa like: e pale i ka mea hoʻohana i ka mask mai nā maʻi ma kahi kokoke, a me ka pale ʻana i nā poʻe i hui pū me ka mea maʻi e kau ana i ka mask.
Hiki i nā mea noiʻi ke hoʻomaopopo pū i nā wahi hana o nā mea ma ka pae atomika.Hāʻawi kēia iā lākou a me nā mea ʻē aʻe e loaʻa i nā pilina hana-hana e hana i nā mea hoʻokumu ʻia ʻo MOF.
Hoʻopau i ka chlorine ikaika hou i loko o ka zirconium-based MOF textile composites e hoʻopau i nā hoʻoweliweli olaola a me nā mea hoʻoweliweli.Nūpepa o ka American Chemical Society, Kepakemapa 30, 2021.
