Combustion Synthesis of NiO-YSZ Precursor Nanocomposites for SOFC Anode and Its Characterization
Abstract: In the present work, the mixture of Nickel Oxide-Yttria Stabilized Zirconia (NiO-YSZ) composites of composition, mNiO–(1–m) Zr0⋅9Y0⋅1 O1⋅95 (m = 0⋅4), anode materials was synthesized by combustion process using glycine as fuel and nitrate as oxidizer. The study of prepared nanocomposites has been done by Fourier transform infrared spectroscopy (FTIR), differential thermal analysis-thermo gravimetric analysis (DTA-TGA), X-ray diffraction (XRD) and scanning electron microscopy (SEM) to determine the powder properties. The …

Effect of Hafnium on Nickel-Titanium based Thin Film Coating by DC/RF Magnetron Sputtering Technique
Abstract: Ni-Ti-Hf films as shape memory alloys were successfully prepared by magnetron sputtering technique using individual Ti, Ni and Hf targets. The hafnium content was varied from 6% to 30% and the required film composition was achieved by adjusting the power ratio to the targets. The as-deposited films were amorphous; a post deposition annealing was performed at 700 °C to crystallize the Ni-Ti-Hf films. Structural, compositional and phase-transformation studies were carried …

On the Electrical Conductivity of ZnO Nanocrystals Synthesized by Solvothermal Method
Abstract: ZnO nanocrystals were synthesized using microwave oven technique. The electrical properties of ZnO were studied using impedance spectroscopy. In this work, measurements on the AC and DC conductivities of the pelletized ZnO samples were carried out. The frequency dependence of both AC conductivity and the dielectric constant of nanocrystals of ZnO were investigated in the frequency range 1 Hz–1 MHz. Electrical characterizations using impedance spectroscopy were carried out for pelletized …

Spectroscopic and Electrical Studies of Conducting Polyaniline Composites Embedded Nanostructure Zinc Sulfide
Abstract: Simple and low-cost chemical precipitation method was used for the synthesis of ZnS nanoparticles using zinc precursor and DMF as a stabilizing agent. Na2S was used as the source of sulphur ions. Composites of polyaniline and ZnS nanoparticles have been synthesized by in-situ chemical oxidation method by varying weight percentage of synthesized ZnS nanoparticles with aniline monomer. Optical studies in terms of UV-Vis and fluorescence show the positive effect of …
