Cov khoom siv roj av ferric (III) oxide, yog cov khoom siv sib nqus zoo uas tau siv dav hauv ntau yam kev siv. Nrog kev nce qib ntawm Nanotechnology, kev txhim kho ntawm nano-qhov loj ferric oxide, tau qhib tshiab rau nws cov kev siv hauv thaj teb.
Fe3O4 nanopowder, muaj cov nano-qhov loj me ntawm ferric oxide, ua rau muaj cov khoom sib txawv ntawm nws cov counterpart. Qhov loj me me ntawm cov me me ua rau muaj cov npoo av siab rau ntim piv, ua rau muaj kev coj zoo ua kom zoo nkauj thiab txhim kho cov cwj pwm sib nqus me me. Qhov no ua rau FER3O4 nanopowder muaj kev sib tw ua rau cov ntawv thov xws li sib nqus cov ntaub ntawv, kev kho cov pa hluav taws xob, thiab catalyalis.
Ib qho ntawm qhov tseem ceeb tshaj plaws ntawm FER3O4 nanopowder yog nws lub peev xwm nyob rau hauv kev thov biomedical. Vim nws biocompatibility thiab superparamagnetic cwj pwm, nws tau kawm ntau yam rau cov tshuaj tiv thaiv yeeb tshuaj, MRI) tsis sib haum xeeb, thiab hyperthermi kho. Lub peev xwm ua haujlwm rau kev ua haujlwm ntawm Fe3O4 nanopowder nrog cov ligands tshwj xeeb ntxiv txhim kho cov tshuaj tiv thaiv tshuaj ntxiv rau cov nqaij mos rau cov nqaij mos.
Ntxiv rau cov ntawv thov biomedical, FE3O4 nanopowder tau qhia cov qoob loo hauv kev pab ib puag ncig. Nws cov khoom siv sib nqus muaj zog pab kom cov paug tsis zoo los ntawm cov dej thiab cov av los ntawm kev sib nqus kev sib cais txheej txheem. Qhov no ua rau nws muaj txiaj ntsig twj rau kev teeb meem ib puag ncig thiab kev sib tw.
Tsis tas li ntawd, cov khoom catalytic ntawm Fe3O4 nanopowder tau nyiam mloog nyob rau hauv daim teb ntawm catalysis. Cov kev coj ua loj thiab kev coj sib nqus ntawm cov nanopowder ua rau nws tus neeg sib tw uas tsim nyog rau ntau yam kev sib tw catalytic, suav nrog oxidation, txo cov txheej txheem hydrogenation.
Hauv kev xaus, kev txhim kho ntawm Fore3O4 nanopowder tau nthuav dav cov ntawv thov yuav muaj cov khoom siv ntawm cov khoom sib nqus ferric. Nws cov khoom tshwj xeeb ua rau nws muaj ntau yam nrog kev cog lus nyob rau hauv biomedical, ib puag ncig, thiab catalytic teb. Raws li kev tshawb fawb hauv Nanotechnology txuas ntxiv mus ua ntej, ntxiv kev tshawb nrhiav cov peev xwm ntawm Fe3O4 nanopowder yuav tsum tsis lees paub txoj hauv kev lag luam tshiab.
