| Talosaga e ono mafai | O le nanoparticle uʻamea o loʻo faʻaaogaina lautele i le radar absorbers, masini puʻeina mageta, faʻafefe vevela, metallurgy paʻu, faʻapipiʻi tui, mea faʻaopoopo eseese, carbide binder, mea tau eletise, uʻamea uʻamea, vailaʻau kemisi, vali maualuga ma isi vaega. |
Fa'amatalaga:
1. Absorbing mea: uamea nanopowder o loʻo i ai galuega faʻapitoa o le faʻaogaina o galu electromagnetic.O le uʻamea, cobalt, zinc oxide powder ma le carbon-coated metal powder e mafai ona faʻaaogaina i le militeri e avea o se mea e le o vaʻaia ma le lelei o le faʻatinoga o le galu milimita.E mafai ona fa'aogaina e pei o mea fa'amea ma fa'aoga mea e le va'aia fa'apea fo'i ma mea e puipuia ai fa'avevela telefoni fe'avea'i.
2. Ala o Faasalalauga maneta: O le maualuga saturation magnetization ma permeability fua faatatau o le nano uʻamea e lelei ala faʻasalalau faʻamaneta lea e mafai ona faʻaaogaina e fai ma faʻapipiʻi fausaga o ulu lelei.
3. Mea fa'amaumau maneta ma fa'atinoga maualuga: Fa'atasi ai ma le lelei o le fa'asa'o sa'o o le fa'amalositino, fa'amaneta saturation, fa'amaneta fa'amaneta fa'apitoa ma fa'amaneta lelei fa'ama'i, ma isi mea, e mafai ona fa'aleleia atili le fa'atinoga o le lipine ma le tisiki vaivai ma le malosi tele.
4. O le vai mageta: faʻafefete faʻamaneta e faia i le uʻamea, cobalt, nickel ma lona paʻu paʻu e sili ona lelei ma e mafai ona faʻaaogaina lautele i faʻamaufaʻailoga faʻamau, mea faʻafomaʻi, pulea leo, faʻaaliga malamalama.
Tulaga teuina:
Uamea (Fe) nanopowders e tatau ona teuina i totonu o le faʻamaufaʻailoga, aloese mai le malamalama, matutu nofoaga.E lelei le teuina o le vevela o le potu.
