30-50nm Fe3O4 nanoparticles Iron Oxide Madow

Sharaxaad Gaaban:

Ferroferric oxide waa ferromagnetic.Haddii radius qayb uu ku jiro heerka nanometer, waxaa loo yaqaannaa qayb ka mid ah ferromagnetic.Maaddada cusub, nano-ferroferromagnetic, sababtoo ah sifooyinka gaarka ah ee jireed iyo kiimiko, sida saamaynta cabbirka quantum, saamaynta cabbirka yar, saamaynta dusha sare iyo interface, iyo saamaynta tunneling macro quantum, waxay ka dhigaysaa inay ku qabato fiisigiska iyo kimistariga.Ka baxsan guryaha gaarka ah ee ka duwan qalabka magnetic caadiga ah.

Codsiga Fe3O4 nanoparticles:

 

kicin:
Qaybaha Fe3O4 waxaa loo isticmaalaa kicinta falcelinta warshadaha badan, sida wax soo saarka NH3 (habka wax soo saarka Haber ammonia), falcelinta wareejinta biyaha-gaaska heerkulka-sare iyo falcelinta gaasta dabiiciga ah.Sababo la xiriira cabbirka yar ee nanoparticles Fe3O4, aagga weyn ee gaarka ah, iyo simannaanta dusha sare ee nanoparticles, tillaabooyin atomic ah oo aan sinnayn ayaa la sameeyay, taas oo kordhisa korka xidhiidhka ee falcelinta kiimikada.Isla mar ahaantaana, qaybaha Fe3O4 waxaa loo isticmaalaa sida side iyo qaybaha kicinta ayaa lagu dahaadhay dusha sare ee qaybaha si loogu diyaariyo qayb ka mid ah qalabka aadka u fiican ee leh qaab-dhismeedka asaasiga ah, kaas oo aan kaliya ilaalineynin waxqabadka sare ee kicinta, laakiin sidoo kale waxay ka dhigaysa kicinta mid fudud in dib loo warshadeeyo.Sidaa darteed, qaybaha Fe3O4 ayaa si weyn loogu isticmaalay cilmi-baarista taageerooyinka kicinta.

 

Duubista magnetic:
Isticmaalka kale ee muhiimka ah ee nano-Fe3O4 qaybaha magnetic waa in la sameeyo qalabka wax lagu duubo.Nano Fe3O4 iyada oo ay ugu wacan tahay cabbirkiisa yar, qaab-dhismeedkiisa magnetic wuxuu ka beddelayaa dhowr-domain ilaa hal-domain, oo leh awood aad u sarreeya, oo loo isticmaalo qalabka wax lagu duubo magnetic si weyn ayuu u wanaajin karaa saamiga signal-ilaa-sanqa, hagaajinta tayada sawirka, wuuna gaari karaa cufnaanta duubista macluumaadka sare.Si loo gaaro saameynta duubista ugu wanaagsan, qaybaha nano-Fe3O4 waa inay lahaadaan xoog badan oo xoog leh iyo magnetization haraaga, cabbir yar, iska caabin daxalka, iska caabin khilaaf iyo la qabsiga isbeddelada heerkulka.

 

Nuugista Microwave:
Nanoparticles waxay leeyihiin sifooyin muuqaal ah oo aan laga heli karin qalabka caadiga ah ee caadiga ah sababtoo ah saameynta yar ee cabbirka, sida indho-indheynta indhaha, iyo luminta tamarta inta lagu jiro nuugista iftiinka iyo iftiinka iftiinka, kuwaas oo si weyn ugu xiran xajmiga nanoparticles.Daraasaduhu waxay muujiyeen in isticmaalka sifooyinka gaarka ah ee nanoparticles si loogu diyaariyo qalabyada kala duwan ee indhaha ayaa si ballaaran loogu isticmaali doonaa nolol maalmeedka iyo goobaha farsamada sare.Cilmi-baarista hadda ee dhinacan ayaa weli ku jirta heerka shaybaarka.Saamaynta cabbirka tirada nano-particles waxay ka dhigaysaa ifafaale isbeddelka buluugga ah ee nuugista iftiinka hirarka dhererka qaarkood.Nuugista iftiinka mowjadaha kala duwan ee budada nano-particle waxay leedahay ifafaale ballaaran.Iyada oo ay ugu wacan tahay awooddeeda magnetic sare, Fe3O4 magnetic nanopowders waxaa loo isticmaali karaa nooc ka mid ah walxaha nuugaya ferrite, kaas oo loo isticmaalo nuugista microwave.

 

Ka saarista wasakhowga biyaha iyo soo kabashada birta qaaliga ah:
Horumarka degdega ah ee warshadaynta, wasakhowga biyaha ee la socda ayaa noqday mid aad u daran, gaar ahaan ions birta ee jirka biyaha, wasakhowga organic-ga ah ee ay adagtahay in la naaquso, iwm, kuwaas oo aan si fudud loo kala saarin daaweynta ka dib.Haddii qalab birlabeed ah la isticmaalo, way sahlanaan kartaa kala saarida.Daraasaduhu waxay ogaadeen in marka Fe3O4 nanocrystals loo isticmaalo in lagu dhajiyo ion bir ah oo sharaf leh sida Pd2+, Rh3+, Pt4+ ee hydrochloric acid distillate, awoodda ugu badan ee Pd 2+ waa 0.103mmol·g -1 iyo awoodda ugu badan ee adsorption ee Rh3+ waa 0.149mmol·g -1, awoodda xajinta ugu badan ee Pt4+ waa 0.068mmol·g-1.Sidaa darteed, magnetic Fe3O4 nanocrystals sidoo kale waa xal wanaagsan oo birta qaaliga ah xayeysiiska, taas oo muhiimad weyn u leh dib-u-warshadaynta biraha qaaliga ah.

 

Xaaladda Kaydinta:

Fe3O4 nanoparticles waa in lagu keydiyaa meel xiran, ka fogow iftiinka iyo meel qallalan.Kaydinta heerkulka qolku waa OK.
