In this review paper, a critical analysis was carried out to investigate the effect of cathodic potential, bath temperature, time and nature of substrates on the ZnO thin films synthesized by electrodeposition technique. XRD patterns of the various deposited films were studied to examine the structural characteristics of the Nanostructured ZnO thin films. From the XRD patterns of the different ...

Synchrotron radiation X-ray diffraction (XRD) patterns from an extensively ball-milled iron alloy powder were collected at 100, 200 and 300 K. The results were analysed together with those using extended X-ray absorption fine structure, measured on the same sample at liquid nitrogen temperature (77 K) and at room temperature (300 K), to assess the contribution of static disorder to the Debye-Wa...

X-Ray Diffraction (XRD) has long been used to determine the atomic-scale structure of materials. This technique is based on the fact that the wavelength of X-rays is comparable to the distances between atoms in condensed matter. When a material exhibiting a long-range (i.e. at least micrometers), periodic atomic order, such as a crystal, is irradiated with X-rays it acts as an extended, well-de...

The aim of this study was to determine a suitable amount of grinding of a flexural test specimen for clinical evaluation of dental ceramics. Three dental ceramics (Crys-Cera, OCC and IPS Empress Cosmo) were selected. Five types of bar-shaped patterns were prepared for a three-point bending test, and four types of disk-shaped patterns for a biaxial flexural test. Ceramic specimens were fabricate...

The structure of a crystalline material may be described by a crystal lattice structure and the locations of atoms in this lattice. The crystal lattice is a 3-dimensional periodic array that defines the symmetries, i.e. shape, of the crystal. There are seven possible crystal lattices: cubic, hexagonal, tetragonal, rombohedral, orthorhombic, monoclinic and triclinic. When we define the possible ...

Hydration and dehydration reaction processes of many organic and inorganic compounds accompany phase changes, and X-ray diffraction (XRD) is a very powerful technique for studying the reaction processes. Thermal analysis is another important technique often used to obtain information needed for understanding the reaction processes. Commercially available instruments for XRD and thermal analysis...

co2+ & er3+ co-doped zno nanocrystals were synthesized by the hydrothermal method at 180°c and ph= 12 for 48 h. powder xrd patterns indicate that the zn1-2xerxcoxo crystals (0.00

the aim of this research is preparation of sno2 nanowires by means of thermal chemical reaction vapor transport deposition (tcrvtd) method from sno powders. the morphology, chemical composition and microstructure properties of the nanowires are characterized using field emission scanning electron microscope (fe-sem), eds, and xrd. the xrd diffraction patterns reveal that the sno2 nanowires have...
