Sr6Nb10O30–Nb2O5 nanocomposite was synthesized in 2M NaOH aqueous solution. A stoichiometric 1:1 Sr:Nb molar ratio hydrothermal method at 120°C was used to synthesize this nanocomposite. Sr(NO3)2 and Nb2O5 were used as raw materials. The synthesized nanomaterials were characterized by powder X-ray diffraction (PXRD) technique. It was found that Sr6Nb10O30 was crystallized in tetragonal crystal ...

The advantage of PARMS for the manufacturing of high performance low loss coatings is demonstrated with UVand VIS band pass filter based on HfO2 respectively Nb2O5 and SiO2.

Immiscible metals due to their inherent specs are insoluble over the steady state. Developing an innovative approach to this issue would be fascinating and challenge the overriding rules. Herein, we proffer the principles of synthesis of Cu-Nb nanocomposites using electrochemical deoxidation route. This method consists of the cathodic electrolysis of the nanoparticles Cu-Nb2O5 through the...

Surface-enhanced Raman scattering technique, as a powerful tool to identify the molecular species, has been severely restricted to the noble metals. The surface-enhanced Raman scattering substrates based on semiconductors would overcome the shortcomings of metal substrates and promote development of surface-enhanced Raman scattering technique in surface science, spectroscopy, and biomedicine st...

The molecular structures and reactivity of tantalum oxide-supported metal oxide (V2O5, Nb2O5, CrO3, MoO3, WO3, and Re2O7) catalysts were determined by Raman spectroscopy and the methanol oxidation chemical probe reaction, respectively. The metal oxides form a twodimensional surface metal oxide overlayer on the tantalum oxide support. Under ambient conditions, the hydrated surface metal oxide sp...

A method of fluorination assisted electrothermal vaporization inductively coupled plasma mass spectrometry (FETV-ICP-MS) was developed to directly determine the trace impurities in niobium pentaoxide solid powder in which a poly(tetrafluoroethylene) (PTFE) emulsion was used as fluorinating modifier to promote the vaporization of refractory elements from a graphite furnace and to avoid the forma...
