NiAl2O4 and cobalt‐doped NiAl2O4 nanocrystals were grown in a SiO2 amorphous matrix at around 1073 K by heating the dried gels from 333 to 1173 K at the rate of 1 K/min. The formations of NiAl2O4 and cobalt‐doped NiAl2O4 nanocrystals in SiO2 amorphous matrix were confirmed through X‐ray powder diffraction, Fourier transform infrared spectroscopy, differential scanning calorimeter, transmission electron microscopy (TEM), and optical absorption spectroscopy techniques. The TEM images revealed the uniform distribution of NiAl2O4 and cobalt‐doped NiAl2O4 nanocrystals in the amorphous SiO2 matrix and the size was found to be ∼5–8 nm.
The influence of synthesized nano-sized TiO2 particles on the ionic transport properties of PEO (... more The influence of synthesized nano-sized TiO2 particles on the ionic transport properties of PEO (polyethylene oxide)-based composite polymer electrolytes (CPEs) was investigated in this study. The nano-sized TiO2 particles with pure anatase phase can be synthesized by a developed process. It was found that the ionic conductivity of the TiO2 modified CPE increases with a decrease in the grain size

The synthesized Li[NixLi(1−2x)/3Mn(2−x)/3]O2 (0≤x≤0.5) powders were confirmed to be layered structure with a space group of R3¯m by X-ray diffraction (XRD) analysis. The extra diffraction peaks between 20° and 30° in the 2θ scale indicates the superlattice ordering of Li, Ni and Mn in the transition metal layer. Further,
