Le "tupu o mea fou" - graphene

1.Graphene ua lauiloa o le "tupu o mea fou", o loo maua i le taimi nei le thinnest, le malosi sili masini, o le conductivity eletise ma vevela sili ona malosi o se nanomaterials fou, i tagata faatau eletise, biomedicine, aerospace militeri, masini semiconductor, puipuiga o le siosiomaga. ma isi matā'upu e tele fa'amoemoega, o lona tagata na maua na manumalo i le 2010 Nobel Prize in physics.

2. Monolayer graphene o se mea kaponi lua-dimension e aofia ai se vaega o carbon atoms faʻapipiʻi faʻamau i se fausaga mama benzene. O le graphene fa'alua-lua e fa'atatau i se mea e lua-dimensional carbon e aofia ai vaega e lua o carbon atoms o lo'o fa'apipi'iina i lea taimi ma lea taimi i totonu o se fausaga mama benzene i auala eseese fa'aputu, ma multi-layer graphene e fa'asino i se mea e lua-dimensional carbon e aofia ai le tolu i le sefulu. fa'apipi'i o fa'atama kaponi i lea taimi ma lea taimi i se fausaga mama benzene i auala fa'aputu eseese.

3.O le pito i luga o le filifili alamanuia graphene o punaoa minerale graphite ma meafaigaluega gaosiga; O le ogatotonu o le graphene ata ma le graphene pa'u gaosiga; O fa'aoga autu i lalo ole malosi fou, vali, soifua maloloina tele, fa'asao malosi ma le puipuiga o le siosiomaga, mea fou vaila'au, fa'amatalaga fa'aeletoroni ma isi pisinisi e ono.
