PX-phase PbTiO 3 (PT) nanowires were synthesized by microwave-hydrothermal process, and their microstructures were characterized by electron microscopy. The PX-phase PT nanowires exhibit acicular morphology with diameter sizes of 20–80nm and length over 1µm. They tend to grow into a regular structure with parallel arrangement along their long axis in the [001] direction. Selected area electron...
Rod-like and star-like nanocrystalline rutile titania were prepared by a sonochemical method in TiCl 4 /HCl solution. The product was investigated by XRD, TEM, SAED, and HRTEM. The results indicate that the product is purely rutile. The formation of rutile titania may be due to rutile's inherent high-temperature stability. The appearance of star-like structures should be attributed to the...
