Features and Benefits

Preparation of new stabilized, oxide ion-conducting, bismuth vanadate phases by a microwave assisted method, from V2O5, Bi2O3 and other solid oxides, was reported. These ceramics show promise in solid oxide fuel cells, water-vapor electrolyzers and oxygen sensors.

In this work, preparation and characterization of a novel nanocomposite containing bismuth oxide (Bi(2)O(3)) nanoparticles and multiwalled carbon nanotubes (MWCNTs) was presented. Powder X-ray diffraction (XRD) studies revealed that as-synthesized Bi(2)O(3) nanoparticles are crystalline and belong to α-phase with monoclinic

The novel strain-driven morphotropic phase boundary (MPB) in highly strained BiFeO(3) thin films is characterized by well-ordered mixed phase nanodomains (MPNs). Through scanning probe microscopy and synchrotron X-ray diffraction, eight structural variants of the MPNs are identified. Detailed polarization configurations
