Nanocrystalline cobalt ferrite as a magnetic black pigment was synthesized via coordinated precursors with a significant decrease of the synthesis temperature using citric acid as a coordinating agent. The structure and properties of the cobalt ferrite powder were characterized by X-ray diffraction (XRD), colorimetric analysis (L*a*b* color parameters), diffuse reflectance spectroscopy and vibr...

ZnO nanocrystalline powder was successfully synthesized via co-precipitation method coupled with high annealing treatment. X-ray diffraction analysis revealed that the NPs have a pure hexagonal wurtzite structure mean crystallite size of approximately 59 nm. FESEM observations along EDS indicated formation fine particles in nanoscale regime, shape and purity. Both Raman photoluminescence charac...

Electrolyte powders with low sintering temperature and high-ionic conductivity can considerably facilitate the fabrication performance of solid oxide fuel cells (SOFCs). Gadolinia-doped ceria (GDC) is a promising electrolyte for developing intermediate- low-temperature (IT LT) SOFCs. However, conventional GDC usually above 1200 °C unless additives are used. In this work, nanocrystalline powder ...

The properties of nanocrystalline materials are essentially determined by the grain size and the properties of the grain boundaries of the respective material. Using PAC for the investigation of nanocrystalline materials new information about structural properties and, in case of nanocrystalline semiconductors, electronic properties are obtained. In combination with “classical” experimental tec...
