Enwere ike iji multifunctional MOF nke dabeere na fiber mejupụtara ihe mejupụtara emebere ebe a dị ka ákwà nchebe megide iyi egwu ndu na kemịkal.

Ihe mejupụtara fiber na-egosi ọrụ biocidal ngwa ngwa megide nje bacteria Gram-negative (E. coli) na gram-positive bacteria (Staphylococcus aureus), na ụdị ọ bụla nwere ike belata ruo 7 logarithms n'ime nkeji ise.
Ngwakọta MOF/fiber nke nwere chlorine na-arụ ọrụ nwere ike iwetu sọlfọ mọstad na ngwa ngwa 2-chloroethyl ethyl sulfide (CEES) na ọkara ndụ nke na-erughị nkeji atọ.
Otu ndị nyocha sitere na Mahadum Northwwest ewepụtala akwa nwere ọtụtụ ihe mejupụtara nke nwere ike iwepu ihe iyi egwu ndu (dị ka coronavirus ọhụrụ na-akpata COVID-19) na ihe iyi egwu kemịkal (dị ka ndị eji agha kemịkal).
Mgbe emechara ákwà ahụ egwu, enwere ike iweghachi ihe ahụ na ọnọdụ mbụ ya site na ọgwụgwọ ịcha ọcha dị mfe.
Omar Farha nke Mahadum Northwwest kwuru, sị: "Inwe ihe eji arụ ọrụ abụọ nwere ike ime ka ọgwụ kemịkal na ihe ndị na-egbu egbu na-arụ ọrụ n'otu oge dị oke egwu n'ihi na mgbagwoju anya nke ijikọta ọtụtụ ihe iji rụchaa ọrụ a dị oke elu," , nke a bụ ntọala nke nkà na ụzụ.
Farha bụ prọfesọ kemịkalụ na Weinberg School of Arts and Sciences na onye na-emekọ ihe ọnụ nke ọmụmụ ihe ahụ. Ọ bụ onye otu International Institute of Nanotechnology na Mahadum Northwwest.
MOF/fiber composites gbadoro ụkwụ na nyocha mbụ nke ndị otu Farha mepụtara nanomaterial nke nwere ike ime ka ihe ndị na-egbu egbu egbu egbu. Site na obere ọrụ ụfọdụ, ndị na-eme nchọpụta nwekwara ike ịgbakwunye ọgwụ nje na nje bacteria na ihe.
Faha kwuru na MOF bụ "ogbo ịsa ahụ nke ọma." A na-eji ọtụtụ oghere emepụta ihe ndị nwere nha Nano, nke nwere ike ọnyà gas, vapor na ihe ndị ọzọ dị ka sponge ọnyà mmiri. N'ime akwa ihe mejupụtara ọhụrụ, oghere nke MOF nwere ihe na-akpali akpali nke nwere ike ime ka kemịkal na-egbu egbu, nje na nje bacteria rụọ ọrụ. Enwere ike kpuchie nanomaterials porous na eriri akwa.
Ndị nchọpụta chọpụtara na MOF / fiber composites gosipụtara ọrụ ngwa ngwa megide SARS-CoV-2, yana nje bacteria Gram-negative (E. coli) na gram-positive bacteria (Staphylococcus aureus). Na mgbakwunye, MOF/fiber composites nke jupụtara na chlorine na-arụ ọrụ nwere ike mebie gas mọstad na analogues ya ngwa ngwa (2-chloroethyl ethyl sulfide, CEES). Nanopores nke ihe MOF nke a na-ekpuchi na akwa akwa na-eme ka ọsụsọ na mmiri gbapụ.
Farha gbakwụnyere na ihe ngwakọta a nwere ike ịgbatị n'ihi na ọ chọrọ naanị akụrụngwa nhazi akwa akwa eji eme ihe ugbu a na ụlọ ọrụ. Mgbe ejikọtara ya na ihe mkpuchi, ihe ahụ kwesịrị inwe ike ịrụ ọrụ n'otu oge ahụ: iji chebe onye na-ekpuchi ihe mkpuchi site na nje ndị dị n'akụkụ ha, na iji chebe ndị mmadụ na-akpakọrịta na onye butere ihe mkpuchi ahụ.
Ndị na-eme nchọpụta nwekwara ike ịghọta saịtị ndị na-arụ ọrụ na ọkwa atọm. Nke a na-enye ha na ndị ọzọ ohere ịnweta njikọ nhazi-arụmọrụ iji mepụta ihe ndị ọzọ dabeere na MOF.
Mee ka chlorine na-arụ ọrụ na-emegharịgharị n'ime ihe mejupụtara MOF textile nke dabere na zirconium iji kpochapụ ihe iyi egwu ndu na kemịkal. Akwụkwọ akụkọ nke American Chemical Society, Septemba 30, 2021.
