Nickel ferrite (NiFe 2 O 4 ) nanoparticles were successfully synthesized via a hydrothermal process and characterized by X-ray diffraction and transmission electron microscope techniques. The effects of reaction temperature, holding time, and RH ratio (isopropyl alcohol/water) were discussed. The NiFe 2 O 4 nanoparticles could be obtained at 601C within 3 h. The crystallization of the spinel ferrites was promoted by the increase in reaction temperature, holding time, and RH ratio.B. Ghate-contributing editor

CdMoO 4 nano-particles were successfully synthesized by a hydrothermal process at a low temperature of 901C, and the powders were characterized in detail by X-ray diffraction, transmission electron microscopy, scanning electron microscopy, and photoluminescent spectra techniques (PL), respectively. CdMoO 4 particles could be obtained under the hydrothermal condition from micrometer to nanometer sizes by varying their precursors. The PL spectra results showed that the optical properties of CdMoO 4 crystallites obviously relied on their particle sizes.G. Patzke-contributing editor
