The hexagonal P 63/mmc crystal structure of BaFe12O19 hexaferrite [37, 38] and the cubic crystal structure F d -3 m of spinel ferrite NiFe2O4 [39, 40] according to JCPDS card 54-0964 were found to have similar results by other studies.

Also, the intensities of some of these peaks differed from those of the Joint Committee for Powder Diffraction Standards (JCPDS) card: the intensity of the (011) plane was extremely weak, and those of the (002) and (211) planes were relatively strong, indicating the foil had a preferred orientation.
These figures denote the locations of the SAD pattern as numbers.

All result reported from available literatures are in accordance with JCPDS card number 070-7080 [1,33], 065-3411 [28], 070-1225 [22], and 036-1451 [30], which allows the result to be indexed as a hexagonal wurtzite crystalline structure of ZnO.

Thus, atomic diffusivity is enhanced through the creation of a large number of structural defects.
[17] JCPDS Card No. 38 0419

SnO2 nanoparticles with rutile structure and indexed peaks were in good agreement with earlier reported values (JCPDS 41-1445).
XRD peaks were in great concurrence with a reference pattern (DB Card No. 9007433) of SnO2.
As the glucose interacts, H+ ion is formed combining with adsorbed anion which further reduces this oxygen (adsorbed) to O2 and releases electrons (equation.3) H++O2−(ad) →O2+2e− (red) (3) The change in the conductivity can be observed as the electrons are quickly transported to the contact electrode which depicts that the glucose concentration is in direct proportion to the number of electrons released which in turn results in increased sample conductivity.

They are consistent with the standard pattern for JCPDS Card No. (36-1451 and 05-0586) and confirmed that ZnO-CaO nanoparticles had been formed.
Recycling of the ZnO-CaO NPs catalyst Yielda (%) Number of cycles 90 1 89 2 85 3 84 4 a Isolated yield after chromatography Conclusions In summary, an efficient protocol for the synthesis of indole derivatives was described with the reaction of isatin and amines using ZnO-CaO NPs as an inexpensive and reusable catalyst in ethanol.

The number in the parenthesis indicates the corresponding crystal plane.
According to the standard of JCPDS card of 04-0783 from ASTM, the XRD patterns indicate that the AgNWs was crystallized.

The diffraction peaks of all the samples are in good agreement with the standard Joint Committee on Power Diffraction Standards(JCPDS) card of the monoclinic scheelite BiVO4(No.14-0688) and there has no diffraction peaks of the tetragonal scheelite BiVO4(No.14-0133).
As is known to all, both the efficiency of light utilization and the number of active sites are the most important parameters contributing to high photocatalytic activity.

According to JCPDS card No. 88–2348, these peak positions belong to tetragonal rutile structure of pristine SnO2.
This condition pushes a greater number of Al atom doped into SnO2 lattice either via loading in the O atomic vacancy or by occupying the position of the Sn atom owing to substitution.

Fig. 8 shows the X-ray diffraction peaks of our samples matches with the peaks of standard card (Matched with JCPDS, PDF number 10-173, 35-798), hence no intermetallic formation has occurred as illustrated in [15].
