I-Ferric oxide, eyaziwa nangokuthi i-iron(III) oxide, iyinto eyaziwayo kazibuthe esetshenziswe kabanzi ezinhlelweni ezahlukahlukene. Ngokuthuthuka kwe-nanotechnology, ukuthuthukiswa kwe-nano-size ferric oxide, ikakhulukazi i-Fe3O4 nanopowder, kuvule amathuba amasha okusetshenziswa kwayo emikhakheni eminingi.
I-Fe3O4 nanopowder, ehlanganisa izinhlayiya ezinosayizi we-nano we-ferric oxide, ibonisa izici eziyingqayizivele kazibuthe ezihlukile kozakwabo ngobuningi. Usayizi omncane wezinhlayiya uphumela endaweni ephezulu ukuya kusilinganiso sevolumu, okuholela ekusebenzeni okuthuthukisiwe nokuziphatha okuthuthukisiwe kazibuthe. Lokhu kwenza i-Fe3O4 nanopowder ibe yikhandidethi elithembisayo lezinhlelo zokusebenza ezifana nemidiya yokugcina kazibuthe, amadivaysi e-biomedical, ukulungiswa kwemvelo, kanye ne-catalysis.
Enye yezinzuzo ezibaluleke kakhulu ze-Fe3O4 nanopowder amandla ayo ezinhlelweni ze-biomedical. Ngenxa ye-biocompatibility yayo kanye nokuziphatha kwe-superparamagnetic, iye yacwaningwa kabanzi ukuze kuthunyelwe izidakamizwa eziqondiwe, i-magnetic resonance imaging (MRI) yokuqhathanisa, kanye nokwelashwa kwe-hyperthermia. Amandla okusebenzisa ubuso be-Fe3O4 nanopowder enama-ligands athile athuthukisa amandla ayo okulethwa kwezidakamizwa okuhlosiwe, okuvumela ukulethwa okunembile kwama-ejenti okwelapha ezicutshini ezigulayo.
Ngaphezu kwezicelo ze-biomedical, i-Fe3O4 nanopowder ibonise isithembiso ekulungiseni imvelo. Izici zayo kazibuthe zivumela ukususwa okusebenzayo kokungcola emanzini nasenhlabathini ngezinqubo zokuhlukanisa kazibuthe. Lokhu kuyenza ibe ithuluzi elibalulekile lokubhekana nezinselelo zokungcoliswa kwemvelo kanye nokulungisa.
Ngaphezu kwalokho, izakhiwo ze-catalytic ze-Fe3O4 nanopowder zidonse ukunaka emkhakheni we-catalysis. Indawo ephakeme kanye nokuziphatha kazibuthe kwe-nanopowder kuyenza ibe ikhandidethi elifanele lokusabela okuhlukahlukene kwe-catalytic, okuhlanganisa izinqubo ze-oxidation, ukunciphisa, kanye ne-hydrogenation.
Sengiphetha, ukuthuthukiswa kwe-Fe3O4 nanopowder kunwebe ukusetshenziswa okunamandla kwe-magnetic ferric oxide. Izakhiwo zayo ezihlukile ziyenza ibe yinto eguquguqukayo enamathemba athembisayo emikhakheni ye-biomedical, imvelo, kanye ne-catalytic. Njengoba ucwaningo lwe-nanotechnology luqhubeka nokuthuthuka, ukuhlolwa okwengeziwe kwamakhono e-Fe3O4 nanopowder kulindeleke ukuthi kuvumbulule amathuba amasha okusetshenziswa kwayo ezimbonini ezihlukahlukene.
