Ie omomi tioata fa'apolokalame mea tu'ufa'atasi e fa'aaogaina e fa'aumatia ai mea fa'amata'u olaola ma vaila'au. Punavai ata: Northwestern University
O mea fa'apipi'i fa'apipi'i fa'avae a le MOF e mafai ona fa'aaogaina e fai ma 'ie puipui mai mea fa'amata'u mai meaola ma vaila'au.
E tele galuega ma fa'afouina N-chloro fa'avae insecticidal ma fa'a'a'ai 'ie e fa'aogaina ai se fa'avaa fa'aola zirconium u'amea malosi (MOF)
O mea fa'apipi'i alava o lo'o fa'aalia ai gaioiga fa'asao vave e fa'asaga i siama Gram-negative (E. coli) ma siama Gram-positive (Staphylococcus aureus), ma e mafai ona fa'aitiitia fa'aletonu ta'itasi e o'o atu i le 7 logarithms i totonu ole 5 minute.
MOF/fiber composites ua tumu i chlorine malosi e mafai ona filifili ma vave faʻaleagaina le sinapi sulfur ma lona vailaʻau faʻatusa 2-chloroethyl ethyl sulfide (CEES) ma le afa-ola e itiiti ifo i le 3 minute
O se vaega suʻesuʻe mai Northwestern University ua atiaʻe se ie tuʻufaʻatasiga tele e mafai ona faʻaumatia ai faʻamataʻu olaola (pei o le coronavirus fou e mafua ai le COVID-19) ma faʻamataʻu vailaʻau (e pei o mea na faʻaaogaina i le tau vailaʻau).
A maeʻa ona faʻamataʻu le ie, e mafai ona toe faʻafoʻisia mea i lona tulaga muamua e ala i se togafiti faʻamaʻi faigofie.
"O le i ai o se mea e lua e mafai ona faʻaaogaina e mafai ai ona faʻaaogaina vailaʻau ma meaola oona e taua tele ona o le lavelave o le tuʻufaʻatasia o mea e tele e faʻamaeʻa ai lenei galuega e maualuga tele," o le tala lea a Omar Farha o le Northwestern University, o ia o se faʻavae metal-organic poʻo MOF tagata tomai faapitoa. , o le faavae lea o tekinolosi.
O Farha o se polofesa o kemisi i le Weinberg School of Arts and Sciences ma le tusitala tutusa o le suʻesuʻega. O ia o se sui o le International Institute of Nanotechnology i Northwestern University.
MOF/fiber composites e fa'avae i luga o su'esu'ega muamua lea na fausia ai e le 'au a Farha se nanomaterial e mafai ona fa'agata ai neura oona. E ala i nisi o gaioiga laiti, e mafai foi e tagata suʻesuʻe ona faʻaopoopoina antiviral ma antibacterial agents i mea.
Fai mai Faha o le MOF o se "omomi taele saʻo." O mea e lapopo'a Nano ua mamanuina ma le tele o pu, e mafai ona maileia le kesi, ausa ma isi mea e pei o se omomi e maileia vai. I le ie fou fou, o le lua o le MOF o loʻo i ai se faʻamalosi e mafai ona faʻagata ai vailaʻau oona, siama ma siama. E faigofie ona ufiufi nanomaterials porous i alava ie.
Na maua e le au suʻesuʻe o le MOF/fiber composites na faʻaalia vave gaioiga e faasaga i le SARS-CoV-2, faʻapea foʻi ma siama Gram-negative (E. coli) ma siama Gram-positive (Staphylococcus aureus). E le gata i lea, o le MOF/fiber composites e tumu i chlorine malosi e mafai ona vave fa'aleagaina le kasa sinapi ma ona vaila'au fa'atusa (2-chloroethyl ethyl sulfide, CEES). O nanopores o mea a le MOF o loʻo ufiufi i luga o le ie e lava le lautele e faʻataga ai le afu ma le vai e sola.
Fai mai Farha, o lenei mea tuʻufaʻatasia e mafai ona faʻalauteleina aua e manaʻomia ai mea faʻapitoa e gaosia ai ie o loʻo faʻaaogaina nei i pisinisi. Pe a faʻaogaina faʻatasi ma se matapulepule, e tatau ona mafai ona faʻatino le mea i le taimi e tasi: e puipuia ai le tagata o loʻo fai ufimata mai faʻamaʻi i totonu o latou pitonuʻu, ma puipuia tagata taʻitoʻatasi e faʻafesoʻotaʻi ma le tagata pisia o loʻo ofuina le matapulepule.
E mafai fo'i ona malamalama tagata su'esu'e i nofoaga fa'agaoioi o meafaitino ile tulaga atomika. O lenei mea e mafai ai e i latou ma isi ona maua ni feso'ota'iga fa'atulagaina-fa'atinoga e fai ai isi mea fa'avae fa'avae MOF.
Fa'asa'o le chlorine fa'afouina fa'aola ile zirconium-based MOF textile composites e fa'aumatia ai fa'amata'u fa'aola ma vaila'au. Tusitala a le American Chemical Society, Setema 30, 2021.
