ZnO nanoparticles were synthesised within the pores of the zeolite ferrierite (FER) by a novel molten salt impregnation method and compared to a traditional wet impregnation method. The structure and optical properties were characterised by powder XRD, photoluminescence and UV-visible diffuse reflectance spectroscopy. The XRD results reveal a distinct difference in the effect of the impregnatio...

We report synthesis of ZrO₂ nanoparticles (NPs) using microwave assisted chemical method at 80°C temperature. Synthesized ZrO₂ NPs were calcinated at 400°C under air atmosphere and characterized using FTIR, XRD, SEM, TEM, BET, and EDS for their formation, structure, morphology, size, and elemental composition. XRD results revealed the formation of mixed phase monoclinic and tetragonal ZrO₂ phas...

PMMA based Polymer Gel Electrolytes have been prepared with different concentrations of salt (NaI) by gelation method. This study has been carried out to understand the effect of salt concentration on conductivity of polymer gel electrolyte. The prepared samples are characterized by XRD, optical microscopy, FTIR and Dielectric spectroscopy. The XRD studies revealed that the prepared polymer gel...

Powder of La0.6Sr0.4CoO3-α (LSCO) was synthesized by a combined citrate-EDTA method. The as-synthesized LSCO powder was calcined, respectively at temperatures of 800, 900 and 1000 °C with different heating/cooling rates which are 2, 5, 10 and 15 °C min. The effects of heat treatments on the phase formation of perovskite phase of LSCO were investigated by powder X-ray diffraction (XRD). The XRD ...
