In this paper we present the impedance spectroscopy of ternary solid solutions BiFeO3, TbFeO3 and PbTiO3, prepared by solid-state reaction method. The preliminary structural studies were carried out x-ray diffraction technique, showing formation polycrystalline sample with ABO3 type perovskite structure hexagonal symmetry for Bi0.8Tb0.1Pb0.1Fe0.9Ti0.1O3system at room temperature. Dielectric study ceramic has been characterized in temperature range 175 - 325 0C frequency 100 Hz 1 MHz. maximum...
Bio-nanotechnology has provides extensive research with emergence in biotechnology and nanotechnology which synthesize nanoparticles using bio-organisms like plant parts, bacteria yeasts, algae fungi that is more compatible the green chemistry principles. Copper were biologically synthesized by root extract leaf of Asparagus adscendens Roxb. as a reducing agent. By treatment aqueous solutions CuSO4•5H2O stable copper formed. UV-Visible study revealed quantitative formation or characteristic...
The attractive colours and fragrance produced by the plants is due to specific phytochemicals present in them. They may be tannins, flavonoids, glycosides, saponins, steroids alkaloids. Emblica officinalis, Acacia catechu, concina Hibiscus rosa-sinensis, are medicinal dye yielding belong different families. qualitative analysis carried out for these showed that terpenoids alkaloids all except phlobatannins only catechu. pet ether chloroform extract of officinalis does not show potential oil...
As nanotechnology gains popularity in medicine, there is a growing concern that small nanoparticles (NPs) could accumulate and penetrate deep into the human body, posing potential risks to various organs. To ensure safe usage assess hazards, it crucial conduct toxicological evaluation of ZnO NPs on organs such as kidney. The present study involved synthesis by using hydrothermal method. Pure crystalline phase was confirmed X‐ray diffraction (XRD). SEM images displayed less agglomerated...
Lead-free relaxor ferroelectric, Ba0.85Ca0.15Zr0.05Ti0.95O3 have been fabricated by a hydrothermal method. Single-phase X-ray diffraction patterns conforms very closely to perovskites structure and the samples phase with tetragonal at room temperature. The FESEM image of powder shows cylindrical like crystals. Small grains average grain sizes ∼10 ± 5 nm uniformly distributed all over powder. most intense rings from TEM correspond large crystallites. A broad dielectric anomaly coupled maxima...
Barium Zirconate Titanate-Barium Calcium Titanate (BCT-BZT) is one of the lead-free systems, which exhibits remarkable ferroelectric properties akin to lead-based perovskite materials. In this study, we have synthesized x(Ba0.85Ca0.15)TiO3-(1−x)Ba(Zr0.15Ti0.85)O3 (where x = 0.4, 0.5, 0.6) monophonic powders by hydrothermal method at 150 °C. X-ray diffraction reveals pure tetragonal phase. Scanning electron microscopy (SEM) studies make known that crystal growth uniform due low temperature,...
The solid solutions of Bi0.8Gd0.1Pb0.1Fe0.9Ti0.1O3 have been prepared by the solid-state reaction method. preliminary structural studies were carried out X-ray diffraction technique showing formation polycrystalline sample with ABO3 type perovskite structure hexagonal symmetry for ceramic system at room temperature. Dielectric properties and impedance study this characterized in temperature range to 375 °C frequency 100 Hz–1 MHz. maximum ferroelectric transition (Tc) was 200 °C–260...
Polycrystalline samples of La0.665Bi0.33Ba0.005GdxMn1-xO3 (LBBGMO) (x = 0.25, 0.45, and 0.65) were prepared via using conventional solid–state reaction method. The preliminary structural studies carried out by X-ray diffraction at room temperature (RT). Rietveld refinement analysis data confirmed that for x 0.25 the structure was orthorhombic but co-existence rhombohedral observed 0.65. average crystallite size calculated from W–H plot all reported 20.4753 nm, 16.6014 16.0821 nm 0.45 0.65...
In this study, the structural analysis of samples (1-x)(K0.44Na0.52Li0.04-Nb0.86Ta0.1Sb0.04)-x(BiAlO3) (x = 0, 0.005, 0.007, 0.01, and 0.05) showed that have orthorhombic tetragonal phases. The effect increasing concentration BA in been studied on impedance modulus 100 °C–500 °C temperature range. All were found to exhibit NTCR behavior. AC conductivity conduction increase with temperature. dielectric capacitive behavior also analyzed from study samples.
