Programmable crystalline sponge jira rinoumbwa zvinhu zvinoshandiswa kubvisa biological uye makemikari kutyisidzira. Mufananidzo kunobva: Northwestern University
Iyo multifunctional MOF-based fiber composite material yakagadzirwa pano inogona kushandiswa sejira rekudzivirira kubva kune biological uye makemikari kutyisidzira.
Multifunctional and renewable N-chloro-based insecticidal uye detoxifying textiles inoshandisa yakasimba zirconium metal organic frame (MOF)
Fiber composite material inoratidza kukurumidza kuita biocidal kurwisa mabhakitiriya eGram-negative (E. coli) uye mabhakitiriya eGram-positive (Staphylococcus aureus), uye rudzi rwega rwega runogona kudzikiswa kusvika ku7 logarithms mukati memaminitsi mashanu.
MOF/fiber macomposites akaremerwa nechlorine inoshanda anogona kusarudza uye nekukasira kushatisa sulfur mustard uye kemikari yayo analogue 2-chloroethyl ethyl sulfide (CEES) ine hafu yeupenyu isingasviki maminetsi matatu.
Chikwata chekutsvagisa kubva kuNorthwestern University yakagadzira jira rinoshanda rakawanda rinogona kubvisa kutyisidzira kwebiological (senge coronavirus nyowani inokonzeresa COVID-19) uye kutyisidzira kwemakemikari (seaya anoshandiswa muhondo yemakemikari).
Mushure mokunge jira racho richityisidzirwa, zvinhu zvinogona kudzorerwa kumamiriro ayo epakutanga kuburikidza nekugadzirisa bleaching nyore.
"Kuva nezvinhu zviviri-zvinoshanda izvo zvinogona panguva imwe chete kusashanda makemikari uye biological toxicants kwakakosha nekuti kuomarara kwekubatanidza zvinhu zvakawanda kupedza basa iri kwakakwira," akadaro Omar Farha wekuNorthwestern University, anove simbi-organic framework kana MOF nyanzvi. , iyi ndiyo nheyo ye teknolojia.
Farha ndipurofesa wekemesitiri paWeinberg School of Arts and Sciences uye munyori anowirirana naye wechidzidzo ichi. Iye inhengo yeInternational Institute of Nanotechnology kuNorthwestern University.
MOF/fiber macomposites akavakirwa patsvagiridzo yepakutanga umo timu yaFarha yakagadzira nanomaterial inogona kumisa chepfu nerve agents. Kuburikidza nekumwe mashandiro madiki, vaongorori vanogonawo kuwedzera antiviral uye antibacterial agents kune izvo zvinhu.
Faha akataura kuti MOF i "sponge chaiyo yekugezera." Nano-saizi zvinhu zvakagadzirwa nemakomba akawanda, ayo anogona kuteya gasi, mhute uye zvimwe zvinhu sesiponji inoteya mvura. Mumucheka mutsva unoumbwa, mhango yeMOF ine catalyst inogona kumisa makemikari ane chepfu, mavhairasi uye mabhakitiriya. Porous nanomaterials inogona kuputirwa zviri nyore pamachira emucheka.
Vatsvakurudzi vakaona kuti MOF/fiber composite yakaratidza kukurumidza kuita kurwisa SARS-CoV-2, pamwe neGram-negative bacteria (E. coli) uye Gram-positive bacteria (Staphylococcus aureus). Pamusoro pezvo, maMOF/fiber macomposites akaremerwa nechlorine inoshanda anogona kukurumidza kushatisa gasi remasitadhi nemakemikari analogues (2-chloroethyl ethyl sulfide, CEES). Iwo nanopores eiyo MOF zvinhu zvakaputirwa pamucheka wakakura zvakakwana kutendera ziya uye mvura kuti zvibude.
Farha akawedzera kuti iyi composite zvinhu inokonzeresa nekuti inongoda ekutanga machira ekugadzira machira ari kushandiswa muindasitiri. Kana yakashandiswa pamwe chete nemask, zvinhu zvacho zvinofanirwa kukwanisa kuita panguva imwe chete: kuchengetedza anopfeka mask kubva kumavhairasi ari pedyo navo, uye kudzivirira vanhu vanosangana nemunhu ane hutachiona akapfeka mask.
Vatsvagiri vanogona zvakare kunzwisisa nzvimbo dzinoshanda dzezvinhu padanho reatomu. Izvi zvinobvumira ivo nevamwe kuti vawane hukama-hwekuita hukama kuti vagadzire zvimwe zveMOF-based composite zvinhu.
Immobilize renewable active chlorine mu zirconium-based MOF textile composite kubvisa biological uye makemikari kutyisidzira. Chinyorwa cheAmerican Chemical Society, Gunyana 30, 2021.
