After reduction heat treatment under a CO atmosphere, new diffraction peaks emerge at 2θ = 44.5° and 51.8°, corresponding to the (111) and (200) planes of metallic Ni, as referenced in JCPDS card No. 00-004-0850 (Fig. 1(d)-(f)).

The structures were observed using XRD on Rigaku D/max-2550 PC X-Ray Diffractometer with Cu-Kα radiation source λ= 1.5406 Å, where the patterns were recorded in the diffraction angle (2θ) range from 30° to 80° with step 0.06°.The FT-IR spectra were recorded on a NEXUS-670 FTIR Spectrometer using pressing potassium bromide troche method to identify the functional groups in the samples over the range of wave number 4000~400 cm-1.The morphologies of as-synthesized composites and fiber were observed using S-4800 field FE-SEM after cover with conductive gold.
For Cu-ZnO molar ratios (0.02:1, 0.05:1, 0.08:1, 0.1:1) it was observed that with increasing the Cu concentration, the intensity of diffraction peaks corresponding to face centered cubic structure of Cu (marked with ‘◆’) increased, while compared to pure ZnO with hexagonal wurtzite structure (JCPDS card# 36-1451, a=3.25 Å and c=5.21 Å).

In this sense, a significant increase of the number of applications of these materials as dielectrics, pyroelectrics, sensors and transducers, among others, has become evident in recent decades.

It shows that a large number of spherical and distributed nanoparticles appeared evenly, nanoparticles diameter of nano-ZnO was around 10-30 nm.
In this study, it had been observed that all samples exhibited a hexagonal structure in accordance with the JCPDS database of card number 36–1451 in Fig.

A large number of studies have confirmed that hydroxyapatite (HA) has excellent biocompatibility and bioactivity, and it can form HCA mineralized layer when immersed in SBF solution.
The step size of 2θ was 0.2°, and the experimental results were compared with the JCPDS card.
The existence of a large number of crystal nuclei will limit the subsequent growth of the crystal.

This system contains many homologous compounds of the formula Znk In2Ok+1 (k=integer number) described as a structure with a k number of ZnO layers sandwiched between two In2O3 layers [9].
Polycrystalline structures correspond to cubic bixbyite In2O3, referring to JCPDS standard card No. 96-210-4744 with two broad peaks are located at 2θ of 30.50° and 51.04° corresponding to (222) and (440) diffraction peaks, respectively.

The charged defects in lattice structure grow in number when Al element mixed in ZnO, and free electron is easier to form, the conductivity of the AZO materials increased strongly.
All peaks of the sample can be indexed to hexagonal wurtzite ZnO (JCPDS card no. 36-1451).
The gas sensing mechanism can be described in terms of an adsorption/desorption process of oxygen atthe surface of sensing materials.There are a number of donor defects in the ZnO crystal structure, and Al3+ ion radius is larger than the Zn2 +, therefore it’s easy to form effective Al doping in ZnO crystals.

The strongest diffraction peak at 2θ= 9.455 i.e. d= 9.3427Å (100) and the second {in order} intense peak at 2θ= 19.254 i.e. d= 4.6043Å (200) are in close agreement (in both the cases) with the literature values for the monoclinic Anthracene [JCPDS Card N0:39-1848].
Presence of a possible mesophase for anthracene clusters was not observed. 3.5 Optical Spectroscopy The optical spectra for the anthracene thin films with increasing number of dips are displayed in Fig 7 (a), (b), (c) & (d).
The similarity between the spectra implies that the absorption of the anthracene nucleus prevails in all cases, which, is more or less perturbed by matrix environment in the individual case which differs due to disparity in number of dips.

The hardness number is reported as an average of five measurements.
Wear test configuration Results and Discussion Table 1 shows the elemental composition of the as-cast gray cast iron sample, and it can be seen that silicon and manganese are the main alloying materials with small number of additional elements.
The diffractogram in Fig. 6 shows five strong peaks at the as-cast sample at a position of 2°Theta of 45.01°, 65.25°, 82.61°, 99.177°, and 116.49° corresponds to peaks associated with crystal of alpha iron Fe (011), Fe (020), Fe (121), Fe (022), and Fe (031) respectively, as matched with JCPDS data card.

Introduction Hydroxyapatite (HA) is usually used for a number of biomedical applications in the forms of granules, blocks, coatings, dense bodies [1-4], as composite with polymer and ceramic [5-7], for bone augmentation and middle-ear implants [4].
All samples were analyzed by referred to the standards of the Joint Committee of Powder Diffraction Standards (JCPDS) card number, 09-0432 for HA powder [21].
