Samaynta iyo isticmaalka kubbadaha wax lagu shiido alumina

Nanoparticles ayaa si sii kordheysa loogu isticmaalo cilmi-baarista iyo warshadaha sababtoo ah hantidooda la xoojiyay marka la barbardhigo qalabka bulk.Nanoparticles waxay ka samaysan yihiin qaybo ultrafine ah oo ka yar 100 nm dhexroorka tiro badan oo atamka ah ayaa lagu soo bandhigaa dusha sare. Waxaa la muujiyay in sifooyinka iyo habdhaqanka alaabtu ay si aad ah u beddelaan marka laga dhiso nanoscale. Tusaalooyinka qaar ee kor u qaadida ee dhaca marka kor u kaca qallafsanaanta iyo xoogga, koronto iyo kuleylka kuleylka ayaa lagu daraa nanoparticles
Maqaalkani waxa uu ka hadlayaa sifooyinka iyo isticmaalka alumina nanoparticles. Aluminium waa P group 3rd element, halka ogsijiin waa P group 2nd element.
Qaabka alumina nanoparticles waa budo wareegsan iyo caddaan. Alumina nanoparticles (dareere iyo foomamka adag) ayaa loo kala saaraa inay yihiin kuwo aad u guban kara oo xanaaqa, taasoo keenta cuncun daran oo isha iyo mareenka neefsashada ah.
Alumina nanoparticleswaxaa lagu farsamayn karaa farsamooyin badan, oo ay ku jiraan milling kubbadda, sol-gel, pyrolysis, sputtering, hydrothermal, iyo ablation laser. Ablation laser waa farsamo caadi ah oo loogu talagalay soo saarista nanoparticles sababtoo ah waxa lagu farsamayn karaa in gaaska, vacuum ama dareeraha. Marka la barbardhigo hababka kale, farsamadani waxay leedahay faa'iidooyinka ururinta degdega ah iyo nadiifinta sare ee dareeraha ah ee dareeraha ah ee loo diyaariyey si ka badan dareeraha nano. nanoparticles ee deegaanka gaseous. Dhawaan, farmashiyeyaasha at Max-Planck-Institut für Kohlenforschung ee Mülheim an der Ruhr waxay heleen hab lagu soo saaro corundum, sidoo kale loo yaqaan alfa-alumina, qaab nanoparticles isticmaalaya hab farsamo fudud, kala duwanaansho alumina aad u xasilloon.
Xaaladda meesha alumina nanoparticles loo isticmaalo qaab dareere ah, sida kala firdhisanaanta aqueous, codsiyada ugu muhiimsan waa sida soo socota:
• Hagaajinta cufnaanta, simanaanta, adkaanta jabka, caabbinta gurguurta, caabbinta daalka kulaylka iyo caabbinta naax ee alaabta polymerka ee dhoobada
