Ferric oxide, inozivikanwawo sesimbi (III) oxide, inonyatso kuzivikanwa magineti iyo yakashandiswa zvakanyanya mukushandisa kwakasiyana. Nekufambira mberi kwenanotechnology, kuvandudzwa kwe nano-sized ferric oxide, kunyanya Fe3O4 nanopowder, yakavhura mikana mitsva yekushandiswa kwayo munzvimbo dzakasiyana-siyana.
Fe3O4 nanopowder, inosanganisira nano-saizi zvimedu zveferric oxide, inoratidzira yakasarudzika magineti zvimiro zvakasiyana kubva kune yayo yakawanda. Hukuru hudiki hwezvimedu hunoita kuti pave nepamusoro penzvimbo kusvika kuvhoriyamu reshiyo, zvichitungamira kune yakawedzera reactivity uye yakagadziridzwa magineti maitiro. Izvi zvinoita kuti Fe3O4 nanopowder ive mumiriri anovimbisa wezvishandiso zvakaita semagineti yekuchengetedza midhiya, biomedical zvishandiso, kugadzirisa kwezvakatipoteredza, uye catalysis.
Imwe yemabhenefiti akakosha eFe3O4 nanopowder kugona kwayo mune biomedical application. Nekuda kweiyo biocompatibility uye superparamagnetic maitiro, yakadzidzwa zvakanyanya kune yakanangwa kuendesa zvinodhaka, magineti resonance imaging (MRI) kusiyanisa kuwedzera, uye hyperthermia therapy. Iko kukwanisa kushanda pamusoro peFe3O4 nanopowder neine ligands chaiyo inowedzera kuwedzera kukwanisa kwayo kwekutengesa zvinodhaka zvakanangwa, zvichibvumira kunyatsoendeswa kwemishonga yekurapa kune zvirwere zvinorwara.
Kuwedzera kune biomedical application, Fe3O4 nanopowder yakaratidza chivimbiso mukugadzirisa kwezvakatipoteredza. Magineti ayo anogonesa kubviswa kwakanaka kwezvinosvibisa kubva mumvura nevhu kuburikidza nemagineti yekuparadzanisa maitiro. Izvi zvinoita kuti ive chishandiso chakakosha chekugadzirisa kusvibiswa kwezvakatipoteredza uye kugadzirisa matambudziko.
Uyezve, iyo catalytic properties yeFe3O4 nanopowder yakakwezva kutarisa mumunda we catalysis. Iyo yakakwirira yepamusoro nzvimbo uye magineti maitiro eiyo nanopowder inoita kuti ive yakakodzera mumiriri kune akasiyana-siyana maitiro ekuita, kusanganisira oxidation, kuderedza, uye hydrogenation maitiro.
Mukupedzisa, kuvandudzwa kweFe3O4 nanopowder kwakawedzera kushandiswa kwemagnetic material ferric oxide. Hunhu hwayo hwakasiyana hunoita kuti ive zvinhu zvakasiyana-siyana zvine tarisiro inovimbisa mune biomedical, zvakatipoteredza, uye catalytic minda. Sezvo tsvakiridzo yenanotechnology ichienderera mberi, kumwe kuongorora kwehunyanzvi hweFe3O4 nanopowder kunotarisirwa kuburitsa mikana mitsva yekushandiswa kwayo mumaindasitiri akasiyana.
