At this present task, an attempt done in order to synthesize NiFeCo3O4 ternary thin film electrode by Electrodeposition method. Microstructure of the films studied using X-ray diffraction, energy dispersive X-ray spectroscopy (EDAX) and Field emission (FESEM) scanning electron microscopy. Films Electrochemical property were studied and confirmed with the help of charge discharge techniques using cyclic voltammetry, which confirms that the prepared electrode has excellent electrochemical capacitive behaviour with 757 F g–1 specific capacitance value of at the density in current about 1 mA g–1.

Our research investigates the correlations between domain texture and microstructural features, including crystallographic texture in bulk and thin film polycrystalline materials to understand the development of piezoelectric and other anisotropic properties in a number of rapidly evolving lead free piezoelectric materials. We investigate approaches to understanding polarization distributions by starting from polarization measurements. In addition, 2D and 3D microstructural simulations are carried out in all types of ferroelectrics to rationalize and then engineer their equilibrium and kinetic response. This paper discusses recent findings associated with bulk piezoelectricity, phase stability, and ferroelastic and ferroelectric domain motion for materials such as Ba(Ti0.8Zr0.2)O3-x(Ba0.7Ca0.3)TiO3 (BZT-BCT) and Bi0.5Na0.5TiO3 (BNT). Conventional and synchrotron-based x-ray diffraction, electron and optical microscopy and piezoelectric characterization techniques are employed to assess texture, both as a function of poling and temperature. The coupling between microstructure and the inherent directional biases fundamental to piezoelectric and ferroelectric performance enable consideration of orientation and anisotropy in systems with unique constraints.

AbstractThin films of calcium carbonate were deposited on the surfaces of synthetic substrates using a simple biomimetic pathway. The Nylon 66 fiber knit pre-adsorbed with acidic polymers was used as a template for the controlled deposition of CaCO3 thin film. The presence of the soluble macromolecules on the fiber knit surface was characterized using ATR-FTIR spectroscopy. The characterization of the mineral films was carried out using scanning electron microscope (SEM), X-ray diffraction (XRD) and energy dispersive Xray scattering (EDX) studies.

A simple solvothermal route has been used to prepare SnSe nanowires using SnCl4·4H2O and Selenium powder. The phase, structure, morphology, and optical properties of the as-synthesized products were characterized by powder X-ray diffraction (XRD), scan electron microscopy (SEM), Raman spectroscope (RS) and UV-visible spectrophotometer (UV-vis). The results showed that SnSe nanowires were prepared at 200°C for 24 h and in the length of 150-200μm, and width of 1-1.5μm. The band gap of SnSe nanowires was about 1.67 eV, which was close to the optimum band gap of thin film solar cells.

<p class="AbstractEnglish"><strong>Abstra</strong><strong>ct</strong><strong>:</strong><strong> </strong>Preparation of Barium Titanate thin film (BaTiO3) has been done on Quartz substrate using sol gel method with spin coating technique. A thin film BaTiO3 wase made with a mole variation of 0.4 mol and 0.8 mol at a rotation speed of 3000 rpm. The samples were annealed at 400 ° C with 30 minutes stand-up time and at 900 ° C with 2 hours stand-up time and a heating rate of 5 ° C per minute. Characterization of optical properties samples was performed using UV-Vis spectrometers and characterization of microstructure samples using X-Ray Diffraction (XRD). The particle size was calculated by Scherer's formula. Based on the results of the analysis it was found that mole variation of the solution influenced the absorbance value, intensity, crystality level and BaTiO3 thin film particle size. The greater mole of BaTiO<sub>3</sub> solution the higher then absorbance value. The fewer then number of layers the greater then diffraction peak intensity. More number of layers the greater the level of crystallinity and particle size.</p><p class="KeywordsEngish"> </p><p class="AbstrakIndonesia"><strong>Abstra</strong><strong>k: </strong>Pembuatan lapisan tipis Barium Titanat (BaTiO<sub>3</sub>) telah dilakukan  diatas substrat Quartz menggunakan metode sol gel dengan teknik spin coating.
