Fig. 1(a) show corresponding parameters of the main peak of the lattice constant as calculated from the XRD spectrum are a = 6.050 Å, b = 10.320 Å and c = 4.710 Å, with Pbnm (62) space group (PDF Card No: 01-073-7356) which agree well with work done by Paolella et.al [30].
The XRD peaks observed at 18.2°, 25.7°, 28.2°, 28.8°, and 32.7° correspond to 011, 111, 121, 200, and 131 XRD crystal planes of LiFe0.5Mn0.5PO4, is in agreement with reported reflections (JCPDS 71-0636) [31].
The hexagonal crystalline carbon was indexed to (JCPDS No. 41-1487), which complement the preferential growth of MWCNTs.
Eq.1 Eq.2 Eq. 3 Eq. 4 Where, ωmax is the angular frequency at the maximum impedance; R is the gas constant = 8.314 J/mol K, T is the room temperature = 298 K; n is the number of electrons transferred per molecule of lithium = 1; F is the Faraday’s constant = 96485 C/mol; A is the geometric area of electrode (16 mm diameter; measured from experiment) = 2.01 cm2; C is the concentration of lithium ion in LiFe0.5Mn0.5PO4 = 0.0228 mol/cm3.

XRD pattern of M-SrFe Nps The JCPDS card number that matches the mentioned XRD pattern is 00-024-1207.
The volume of the cell is calculated using the following equation (4) [4, 27]: V=√32 a2c (4) According to JCPDS file no. 00-024-1207, the characteristic peaks of hexaferrite can be observed at 2θ values of 30.30, 32.30, 34.10, 56.80, and 63.20 corresponding to the crystal planes of (110), (107), (114), (2011) and (220) [28].

In this graph, several additional low intensity peaks of TiN were found together with an AlN peak (PDF card #88-2363).
Table 1 EDP measurements together with the phase identification and the corresponding diffraction planes (experimental and theoretical) of Fig. 6b (PDF cards #38-1420 for TiN and #88-2360 for AlN).
Particularly the rings denoted with the numbers 2, 3, 5 and 7 were found to correspond to (111), (200), (220) and (222) TiN Bragg reflections, respectively with fcc cubic structure.
Rings denoted with the numbers 1, 2, 4, 6, and 7 are the same with Fig. 5c and correspond to AlN.

Ferrites have a wide range of applications in microwave absorbance, number of electronic devices as radio, TV sets, integrated non-reciprocal circuits and telecommunication applications [2].
The diffraction patterns revealed a cubic spinel structure for all compositions with good crystallinity and the peaks were indexed using JCPDS Card No. 01-074-2403.

It is quite clear seen that the target is SnO2 with fine polycrystalline grains oriented along the (110)，(101)，(200)，(111)，(211), (220), (002), (221), (112) and (301) planes, respectively, corresponding to the tetragonal rutile structure of SnO2 (JCPDS card NO.41-1445).
Seen from Fig.5c, the crystal grain grow more complete, there are a number of smooth crystal surface, but the emergence of a small amount of abnormal grain can also be seen in Fig.5d.

A number of adsorbents have been used in removing Pb2+ such as , activated phosphate [3], activated carbon [4], etc.
Curve a shows the typical orthorhombic symmetry of Palygorskite (space group P63/m; a = 12.76 Å, b = 17.84 Å and c = 5.241 Å, JCPDS Card No. 82-1873).

The structural models of JCPDS (joint committee on powder diffraction standards) card numbers 9-0169 and 24-033 were respectively used for β-TCP and HA.

HA peaks were occurred to 2θ of 28° and 32°, which are consistent with the standard XRD peaks for HA (JCPDS-ICDD card no 18-0303).

It can be seen that both samples have the Li4Ti5O12 single phase with cubic spinel structure and Fd3m space group (JCPDS card No. 49-0207), indicating that the added sucrose does not affect the spinel structure of Li4Ti5O12.
It can be seen that Sample 1 with the absence of sucrose shows a large dense spherical aggregate structure with smooth surface morphology and each of the spherical grains is made up of a large number of fine cubic crystalline grains, as shown in Fig. 3(b).

Having the narrow band gap of 1.2 eV, this copper oxide-based material comprises of a number of unique properties, namely the magnetic, electrical and optical properties [1].
The main diffraction peaks are readily indexed to monoclinic type CuO as indicated by (-1 1 1) crystal plane according to the JCPDS card (089-5895).
