Nanocrystalline metals prepared by high-energy ball milling

This is a first systematic report on the synthesis of completely nanocrystalline metals by high-energy deformation processes. Pure metals with body-centered cubic (bcc) and hexagonal close-packed (hcp) structures are subjected to ball milling resulting in a decrease of the average grain size to ≈9 nm for metals with bcc and to ≈13 nm for metals with hcp crystal structures.

Mesoporous Molecular Sieve Derived TiO2 Nanofibers Doped

Mesoporous silica spheres were used as templates to prepare 5 to ∼10 nm Sn doped TiO2 (TDT) nanofibers using SnCl4 and TiCl4 as precursors. The as-made nanofibers were crystalline anatase but transformed into the rutile phase after annealing above 700 °C. The Sn dopant amount in the TDT nanofibers can be controlled by changing the molar ratio of SnCl4 to TiCl4.
