Note that these configurations were deduced by the application of the local environment model [32-36] after the fit of the spectra, in which the magnetic moment of an element depends on the number of nearest neighbors (NN) (see ref [8] for more details).
The authors explained these findings by the fact that the structural disorder in binary Fe-Al alloys reinforces the ferromagnetic exchange due to the larger effective number of magnetic NN in the disordered phase compared with the ordered one.

Moreover, the as-prepared ZnO were assembled by large numbers of interleaving nanosheets and formed an open porous structure.
All samples matched closely with their characteristic peaks according to the database of the Joint Committee on Powder Diffraction Standards (JCPDS).
Hexagonal ZnO, monoclinic WO3 (JCPDS 72-1465) and monoclinic Nb2O5 (JCPDS file No. 37-1468) were the major phases detected on the XRD patterns.
The diffraction peaks of 31.8o (100), 34.4o (002), 36.3o (101), 47.5o (102), 56.5o(110), 62.8o (103), 66.3o (200), 67.9o (112) and 69.2o (201) can be indexed to wurtzite ZnO (JCPDS Card No. 36-1451).

From above Fig. 4, it is clear that different peaks and troughs are recorded at different wave numbers.
The peak positions in the Fig. 8 shows the formation of hexagonal wurtzite crystal structures, which are in very good agreement with the standard JCPDS Card No.00-005-0664.Cu doped ZnO also retains the hexagonal wurtzite crystal structure.
The earlier inference is drawn by comparing inter-planar spacing and angle 2θ with JCPDS file.
The JCPDS, file No. 04–0836 for copper, indicates peaks after 2θ= 30˚.
JCPDS card No. 38-0385 for Zn(OH)2, shows a peak at 2θ= 22.134˚ below 30˚.

Cupric oxide (CuO) is a p-type semiconductor with a narrow band gap (1.2 eV) and exhibits a number of interesting properties [3].
These values are consistent with the respective JCPDS (Joint Committee on Powder Diffraction Standards) card No. 45-0937.
By comparasion Fig 2(b) and Fig. 2(c), with the increase of the content of Na2CO3, A large number of CuO sheets agglomerates are shown.

The XRD pattern of CoFe2O4 using NaOH was suitable with XRD standard pattern of CoFe2O4 according to JCPDS Card No. 22-1086 [14].
The successful indicator of the impregnation can be seen in Fig. 1, namely the XRD spectrum appears to be a combination of typical peaks of CaO corresponding to JCPDS Card no. 96-900-6746 (according to the result of Match Program) and with JCPDS Card No. 22-1086 for CoFe2O4 [14].
This number was obtained from measurement 100 dot samples randomly.
The viscosity of the synthesized methyl esters was 4.68 cSt, this number met the prerequisites of methyl esters for biodiesel according to the international biodiesel standard in ASTM-D445, which is between 1.9-6.0 cSt.

We can see that the number of electrons at Mn atom is almost constant during lithium increase, on the other hand, the number of electrons at O atom is increasing with lithium increase.
(a) is number of electrons at Mn atom and (b) is number of electrons at O atom.
Mulliken population analysis for all electrons agreed with the change of number of electrons obtained by previously.

Based on Fig. 2 we can see the XRD pattern of TiO2 material along with the characteristics of the peaks based on JCPDS card number 21-1272 which shows the diffractogram of TiO2 obtained is an anatase phase.
Based on JCPDS card number 26-1136, the results of Fe-TiO2 synthesis containing Fe3O4 compounds can be seen from the 2θ values obtained, namely 35.82o (311) and 63.04o (440).

All samples exhibited distinct diffraction peaks that are characteristic of the anatase phase of titanium dioxide, as identified by the Standards (JCPDS card no. 01-073-1764).
While the peaks observed at 30.81°, 48.04°, and 54.28° in sample S3, corresponding to the plan (211), (321), and (230), respectively, confirmed the presence of the brookite phase, the data obtained were in agreement with the standard JCPDS (card no. 01-075-1582).
The data obtained were in agreement with the JCPDS standard (card no. 01-075-1532) for Ag2O.
While the peaks were observed at 63.16° and 68.85°, corresponding to the (222) and (321) crystal planes, as identified by the Standards (JCPDS card no. 00-018-0576) for AuTi3.
