Size-manipulation synthesis of single-crystalline BaMnO3 and BaTi1/2Mn1/2O3 nanorods/nanowires

Article Abstract:

A size-manipulable synthesis of single-crystalline nanorods/nanowires of barium manganite (BaMnO3) and barium titanium manganite (BaTi1/2Mn1/2O3) is described by using the composite-hydroxide-mediated approach. The ability to synthesize nanorod manganites of a desired length would help in investigating the size-dependent evolution of magnetism, magnetoresistance, nanoscale phase separation and realization of a nanodevice of magnetic sensors.

Core-shell microspherical [Ti.sub.1-x][Zr.sub.x][O.sub.2] solid solution photocatalysts directly from ultrasonic spray pyrolysis

Article Abstract:

The synthesis of [Ti.sub.1-x][Zr.sub.x][O.sub.2] solid solution by a single-step ultrasonic spray pyrolysis method is reported. It is found that [Ti.sub.0.91][Zr.sub.0.09][O.sub.2] solid solution exhibits the highest photocatalytic activity among all the as-prepared samples.

A general approach to porous crystalline TiO2, SrTiO3, and BaTiO3 spheres

Article Abstract:

A general hydrothermal method can be used to prepare monodispersed porous crystalline TiO2, SrTiO3 and BaTiO3 spheres. The formation processes of the porous spheres are proposed according to mechanism analogues to the Kirkendall effect.
