Titanate nanotubes were synthesized by hydrothermal treatment in concentrated NaOH solution followed by HC1 washing.The as-prepared nanotubes were characterized
After being treated in different ways,Zr-Sn-Nb-Fe alloy specimens are exposed in 0.01mol/L LiOH aqueous solution at 350℃ under 16.8 MPa.The examination of micr
