“…The prominence is currently being placed on the development of sensor materials for the detection of LPG that offer high sensitivity, short response and recovery times, superior reproducibility and long-term stability [1,2]. However, most of the sensors developed so far are kinetically slow with a limited sensitivity for the detection below the permissible level of LPG and operate above room temperature; although the detection of LPG at room temperature will be very helpful for the chemical industries and research laboratories [3][4][5].…”

“…X-ray patterns clearly suggesting the formation of a highly crystallized powder. For these samples, X-ray diffraction patterns showed peaks at 2θ = 32.4°, 46.7° and 58.1° which were attributed to the perovskite structure (Singh et al, 2013;Silva et al, 2010). All perovskite structure peaks identificated were indexed as rhombohedral system.…”

Abstract:We reported the synthesis of ink-perovskite/Polyaniline composite electrode material for the separation of sodium chloride solution. These electrode materials are prepared by in situ polymerization process of aniline in the presence of perovskite ceramic material with carbon catalyst surface. This material is having the highest conductivity as a cathode material, environmentally benign and low cost material. The structure and morphological properties of prepared ternary composites are characterized by Fourier transform infrared, X-ray diffraction, SEM and TGA. The electrochemical properties are also investigated using four probe method and cyclicvoltametry method. Electrochemical measurement shows that the conductivity of ternary composites is 128 Scm −1 . Resulting composites are promising cathode material for low power consuming electrolysis process of sodium chloride solution.

In this investigation, neodymium orthoferrite (NdFeO3) nanoparticles has been synthesized through ultrasonic method in the presence of octanoic acid as surfactant. This method comparing to the other methods is very fast and it does not need high temperatures during the reaction. The spherical NdFeO3 nanoparticles with an average particles size of about 40 nm can be obtained at a relatively high calcination temperature of 800 °C for 4 h. Also, product obtained by this method are uniform in both morphology and particles size. The phase composition, morphology, lattice parameters and size of particles in these product are characterized by Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) scanning electron microscopy (SEM) and energy dispersive X-ray spectrometer (EDX). The XRD analysis reveals only the pattern corresponding to perovskite type NdFeO3 which crystallizes in the orthorhombic structure. Energy dispersive X-ray analysis confirms the elemental compositions of the synthesized material.
