The rGO with a high number of oxygen functional groups produced in a short reduction time shows a faster response to analytes.
The obtained values of 2Ɵ were compared with Joint Committee on Powder Diffraction Standards (JCPDS) data files.
The hkl planes of rGO matched with JCPDS Card No. 75-2078 [25].
According to the JCPDS (75-2078) data the prominent peak is at 2ϴ (26.26).
It is observed that this prominent peak shows shift in its position with respective JCPDS.

Besides, it should be noted that all the peaks were indexed to the body-centered cubic structure of Ag3PO4 (JCPDS Card No. 06-0505) [14].
Sample I was mainly constructed by a few Ag3PO4 micro-particles, which exhibited irregular sphere-shape with the diameter ranging from 200 to 700 nm; Sample II contained a number of larger particles with the average sizes of 1~2 μm.
The favorable performance might be attributed to the excellent surface energy (a number of high- index crystal planes), the good dye adsorption ability (larger surface area) as well as the suitable band structure (i.e. narrower band gap).

At the meantime, another reaction between Si and B4C occurred, resulting in the formation of β-SiC as well as a new boron carbide phase in which the ratio of B to C was changed from 4 to a higher number.
The corresponding JCPDS card numbers of the above mentioned phases are 06-0555 for B4C, 19-0178 for B12(C,Si,B)3, 73-1708 for β-SiC, 80-0018 for Si and 71-0097 for B49.9C1.82 respectively.

Last, XRD analyze data was obtained and compared to the JCPDS card to comfirm the phase composition of the samples.
Nucleation temperature was held for a period of time, so that a large number of fine crystal nucleus could be formed.
Fig. 4 XRD curves of fore-and-aft crystallization (a) (b) Fig. 5 SEM picture of fore-and-aft crystallization In Fig. 4, the sample produced a large number of crystals after crystallization heat treatment.

It represents a typical character of the crystalline face centered cubic Co3O4 phase with lattice constant a=8.085Å, which agrees well with the standard crystallographic date (JCPDS card no. 78-1970).
The electrode adsorbed a large number of the electrolyte ions.
It could not offer the ions number of the electrode charging.

Consequently, a great number of studies have been devoted to improve the mechanical properties of sintered HA 2-4.
Nevertheless, MgO peak corresponding to JCPDS card No. 43-1022 was detected in these samples and the intensity of the MgO was found to increase with increasing dopant addition in the HA matrix.
From the point of view of clinical applications as implant material, the presence of Mg ions could be beneficial as a number of studies have shown that there was an increase in interfacial strength for implant with hydroxyapatite surfaces enriched with magnesium 12.

All the diffraction peaks displayed in Figures 1a and 1b could be indexed to the monoclinic phase of WO3 (JCPDS card # 05-0363).
(JCPDS card # 05-0363).
The grain-like structure is similar for different metallic concentrations, but from a different grain size distribution, it can be expected that the number of grain boundaries with the corresponding trap densities may have an influence on the electrical behavior.
Variation in electron scattering parameters, like number or density of grain boundaries, might be responsible for the resistivity and mobility changes observed figures 5a and 5b for different Mo and Ti concentrations respectively. 4.6 Optical properties In figure 6a the optical transmittance and opto-electronic properties of WO3:Mo films are presented in the 300–850 nm spectral range.

From the calculation results of mullite crystal(JCPDS Card number is 15-776), d(001)= 0.289 nm, d(400)= 0.189 nm and d(401)= 0.158 nm, the angles between these planes are f(001)^(400)= 90°, f(001)^(401)= 33.19° and f(400)^(401)= 56.81°.
According to the Anion Coordination Polyhedron Growth Unit Theory Mode [12-13], in the open-system hydrothermal crystallization procedure under normal pressure, the growth unit is the complex formed by the attraction of cation and OH- ions, whose coordination numbers are equal to that of the cation in the crystal to be formed.

Cool pigments that absorb less near-infrared reflecting (NIR) radiation provide a number of advantages.
Fe2O3 and FeAl2O4 peaks were well indexed to JCPDS cards number of 33-0664 and 34-0192 respectively.

CNTs and CNFs have large number of potential applications which include field emission sources, hydrogen storage, catalyst substrate, chemical sensors, scanning probe tip, electrode material, nanoelectronics and mechanical reinforcements [2].
Results and Discussion The rapid decomposition of metal acetates is highly advantage for the formation of nanometer scale catalyst particles and therefore enhances the catalytic activity by increasing the number of surface active sites.
It contains two characteristic peaks at about 26.0° and 43.5°, indexed with 002 and 101 diffraction planes of hexagonal graphite (JCPDS card files, no. 41- 1487), respectively.
