Kugwiritsa ntchito Fe3O4 nanoparticles:

chothandizira:
Fe3O4 particles amagwiritsidwa ntchito ngati chothandizira muzochitika zambiri zamafakitale, monga kupanga NH3 (Njira yopangira Haber ammonia), kutengerako kutentha kwamadzi ndi gasi komanso gasi desulfurization reaction.Chifukwa cha ang'onoang'ono Fe3O4 nanoparticles, lalikulu enieni padziko m'dera, ndi osauka pamwamba kusalala kwa nanoparticles, m'njira atomiki m'njira aumbike, amene kumawonjezera kukhudzana padziko zimachitikira mankhwala.Pa nthawi yomweyo, Fe3O4 particles ntchito monga chonyamulira ndi chothandizira zigawo zikuluzikulu TACHIMATA pamwamba pa particles kukonzekera kopitilira muyeso-chabwino chothandizira particles ndi pachimake-chipolopolo dongosolo, amene osati amakhala mkulu chothandizira ntchito chothandizira, komanso zimapangitsa chothandizira kukhala chosavuta kukonzanso.Choncho, Fe3O4 particles akhala akugwiritsidwa ntchito kwambiri pofufuza zothandizira zothandizira.

Kujambula kwa maginito:
Ntchito ina yofunika ya nano-Fe3O4 maginito particles ndi kupanga maginito kujambula zipangizo.Nano Fe3O4 chifukwa cha kukula kwake kakang'ono, mawonekedwe ake a maginito amasintha kuchokera kumagulu ambiri kupita kumalo amodzi, ndi kukakamiza kwakukulu, komwe kumagwiritsidwa ntchito ngati maginito kujambula zinthu kumatha kusintha kwambiri chiŵerengero cha signal-to-phokoso, kupititsa patsogolo chithunzithunzi, ndi kukwaniritsa. mkulu zambiri kujambula kachulukidwe.Kuti tikwaniritse bwino kujambula zotsatira, nano-Fe3O4 particles ayenera kukhala mkulu coercivity ndi otsalira maginito, yaing'ono, kukana dzimbiri, kukana mikangano ndi kusintha kutentha.

Mayamwidwe a Microwave:
Nanoparticles ali ndi mawonekedwe owoneka bwino omwe sapezeka muzinthu zodziwika bwino chifukwa cha kukula kwazing'ono, monga mawonekedwe osawoneka bwino, komanso kutaya mphamvu pakuyamwa kwa kuwala ndi kuwunikira, zomwe zimadalira kwambiri kukula kwa nanoparticles.Kafukufuku wasonyeza kuti ntchito wapadera kuwala zimatha nanoparticles kukonzekera zosiyanasiyana kuwala zipangizo adzakhala ankagwiritsa ntchito pa moyo watsiku ndi tsiku ndi zamakono minda.Kafukufuku waposachedwa pankhaniyi akadali mu labotale.Kukula kwa kuchuluka kwa ma nano-particles kumapangitsa kukhala chinthu chosinthika cha buluu pakuyamwa kowala kwa utali wina wa wavelength.Kuyamwa kwa kuwala kwa mafunde osiyanasiyana ndi nano-tinthu ufa kumakhala ndi chodabwitsa chofutukuka.Chifukwa cha kuchuluka kwake kwa maginito, Fe3O4 maginito nanopowder atha kugwiritsidwa ntchito ngati mtundu wa zinthu zomwe zimayamwa ferrite, zomwe zimagwiritsidwa ntchito pamayamwidwe a microwave.

Kuchotsa Adsorption kwa zoipitsa madzi ndi kuchira kwachitsulo chamtengo wapatali:
Ndi chitukuko chofulumira cha mafakitale, kuipitsidwa kwa madzi komwe kumayenderako kwakhala kovuta kwambiri, makamaka zitsulo zazitsulo m'madzi amadzi, zovuta zowonongeka zowonongeka, ndi zina zotero, zomwe sizili zophweka kupatukana pambuyo pa chithandizo.Ngati maginito adsorption agwiritsidwa ntchito, Kupatukana kumakhala kosavuta.Kafukufuku wapeza kuti Fe3O4 nanocrystals ntchito adsorb apamwamba ayoni zitsulo monga Pd2+, Rh3+, Pt4+ mu hydrochloric acid distillate, pazipita adsorption mphamvu Pd 2+ ndi 0.103mmol·g -1 ndi pazipita adsorption mphamvu Rh3+ ndi 0.149mmol·g -1, kuchuluka kwa adsorption kwa Pt4+ ndi 0.068mmol·g-1.Choncho, maginito a Fe3O4 nanocrystals ndi njira yabwino yothetsera zitsulo zamtengo wapatali, zomwe ndizofunikira kwambiri pakubwezeretsanso zitsulo zamtengo wapatali.
