O le poloka saito lelei poloka poloka gaosia e malulu suia o le lautele faʻaaogaina i masini, eletise, semiconductors, polycrystalline silicon, monocrystalline silicon, metallurgy, vailaʻau, lavalava, ogaumu uila, avanoa tekonolosi ma vailaʻau ma vailaʻau pisinisi.
O le kalafi ei ai uiga nei:
- Lelei eletise conductivity ma maualuga vevela conductivity
- Maualalo faʻalauteleina vevela ma maualuga teteʻe i vevela faʻateʻia.
- O le malosi faʻateleina i le maualuga vevela, ma e mafai ona tatalia sili atu 3000 tikeri.
- Fale oona vailaʻau ma faigata ona tali atu
- Oe lava lubrication
- Faigofie ona faʻagasolo
