I-Ferric oxide, ekwabizwa ngokuba yi-iron(III) oxide, yinto eyaziwa ngokuba yimagnethi esetyenziswa ngokubanzi kwizicelo ezahlukeneyo. Ngokuqhubela phambili kwe-nanotechnology, ukuphuhliswa kwe-nano-size ferric oxide, ngokukodwa i-Fe3O4 nanopowder, ivule amathuba amatsha okusetyenziswa kwayo kwiinkalo ezininzi.
I-Fe3O4 i-nanopowder, equkethe i-nano-size particles of ferric oxide, ibonisa iimpawu ezikhethekileyo zamagnetic ezahlukileyo kwi-bulk counter. Ubungakanani obuncinci beengqungquthela buphumela kwindawo ephezulu ukuya kumlinganiselo wevolumu, ekhokelela ekuphuculeni ukusebenza kwakhona kunye nokuziphatha okuphuculweyo kwamagnetic. Oku kwenza i-Fe3O4 i-nanopowder ibe ngumgqatswa othembisayo wezicelo ezifana nemidiya yokugcina imagnethi, izixhobo ze-biomedical, ukulungiswa kokusingqongileyo, kunye ne-catalysis.
Enye yeenzuzo ezibalulekileyo ze-Fe3O4 nanopowder yikhono layo kwizicelo ze-biomedical. Ngenxa ye-biocompatibility yayo kunye nokuziphatha kwe-superparamagnetic, ifundwe ngokubanzi malunga nokuhanjiswa kwechiza ekujoliswe kulo, ukuphuculwa kwe-imaging resonance imaging (MRI) kunye nonyango lwe-hyperthermia. Ubuchule bokusebenza ubuso be-Fe3O4 i-nanopowder kunye ne-ligands ethile kwandisa ngakumbi amandla ayo okunikezelwa kweziyobisi ezijoliswe kuyo, okuvumela ukuhanjiswa ngokuchanekileyo kwee-agent zonyango kwizicubu ezigulayo.
Ukongeza kwizicelo ze-biomedical, i-Fe3O4 i-nanopowder ibonise isithembiso sokulungiswa kwendawo. Iimpawu zayo zamagnetic zenza ukuba kususwe ngokufanelekileyo ukungcola emanzini kunye nomhlaba ngokusebenzisa iinkqubo zokuhlukana kwamagnetic. Oku kuyenza ibe sisixhobo esixabisekileyo sokujongana nongcoliseko lokusingqongileyo kunye nemingeni yokulungisa.
Ngaphezu koko, iimpawu ze-catalytic ze-Fe3O4 nanopowder ziye zatsala ingqalelo kwintsimi ye-catalysis. Ummandla ophezulu kunye nokuziphatha kwamagnetic kwe-nanopowder kwenza kube ngumviwa ofanelekileyo kwiindlela ezahlukeneyo zokuphendula, kubandakanywa ne-oxidation, ukunciphisa, kunye neenkqubo ze-hydrogenation.
Ukuqukumbela, uphuhliso lwe-Fe3O4 nanopowder luye lwandisa usetyenziso olunokwenzeka lwe-magnetic ferric oxide. Iipropathi zayo ezizodwa ziyenza ibe yimathiriyeli eguquguqukayo enamathemba athembisayo kwi-biomedical, yokusingqongileyo, kunye nemimandla ye-catalytic. Njengoko uphando kwi-nanotechnology luqhubela phambili, ukuphononongwa okuqhubekayo kwezakhono ze-Fe3O4 nanopowder kulindeleke ukuba kuveze amathuba amatsha okusetyenziswa kwayo kumashishini ahlukeneyo.
