X-ray Diffraction, Rigaku Miniflex II, is use to ensure the structure of ZnO microrod that it is follows a wurtzite structure and the lattice constant of ZnO microrod.
It is confirmed that the samples is follow the wurtzite structure.
These peaks showed the ITO structure on the sample.
This dimension shows that the ZnO structure was formed in micro size.

The results herein are expected to be of great interest for a better understanding of the relationship between structure and properties of biodegradable polymer nanocomposites.
In addition, calcination of the LDH at 500˚C for 5 hours resulted in dehydroxylation of the layered structure with loss of CO2 and interlayer water as previously reported.
It indicates that the structure and the corresponding crystallized domains of the PCL are not perturbed by the presence of hybrid LDHs.
Comparison of the FT-IR spectrum of the reconstructed LDHs with that of the original LDH confirms the successful recovery of the crystal structure.

Results and discussion
Analysis of crystal structure.
The crystal structure of manganese-doped calcium zirconate phosphor conforms to a perovskite structure in the orthorhombic lattice system (JCPDS: 35-0645) belonging to the Pnma{62} space group.
The crystal structure of manganese-doped strontium zirconate phosphor is in accordance with a perovskite structure in the orthorhombic lattice system (JCPDS: 44-0161) belonging to the Pnma{62} space group.
Figure 3 displays the crystal structure of manganese-doped calcium zirconate and manganese-doped strontium zirconate phosphors [2].

The structure and morphological analysis of copolymers is characterized.
As shown in Fig. 3 (a), the PPy polymer has a dense packing structure as plate-like.
It can be ascribed to the prominent structure features of P(PLPY-co-Py), which can allow the electrolyte to better infiltrate into the copolymer and provide ionic channels for polymeric electrode redox reactions.
The high cycling stability was thought to be ascribed to the relatively high conductivities and the prominent structure features.

Experimental results show that all the thin films were smooth, compact and have the kesterite structure.
The structure of the films, and their morphologies, photoelectrical properties were investigated in detail.
The crystal structure of CZTS thin films were determined by X-ray Powder Diffraction (XRD, D-max-Γa, Rigaku) patterns obtained with Cu-Kα (α = 1.5418Å) radiation in the span of angle 10-80°.
As the extension of reaction time, the formation gotten from the SEM are uniform and compact, the chemical composition ratio gotten from the EDS is accurate, and the structure of the CZTS thin films gotten from the XRD is kesterite.

The A-type structure
has been found from La2O3 to Nd2O3.
Only by simple redox reaction a fluorite type structure could be transformed to perovskite structure and vice versa [29].
LaCrO4 adopts a monazite structure with space group P21/n.
Only by a redox reaction a reversible transformation between fluorite type structure and perovskites structure was observed.

The XRD analysis, SEM and TEM images show that sample has the good crystal structure, morphology and carbon coating.
As can be seen, all the peaks can be readily indexed as a olivine structure corresponding to LiFePO4 and no impurity-phase peaks exist, indicating the structure of the samples has not been changed with Ni and Nb co-doping.
The LiFe0.98Ni0.01Nb0.01PO4/C composite has the similar crystal structure with crystallized LiFePO4 phase.

At this age, plaque-shaped structures are larger than the ones observed in 15-day-old animals.
These larger structures are observed in bone mineral both from femur and from parietal bone of animals at one month of age.
Moreover, it is possible to notice the formation of plaque-shaped structures as a process that occurs throughout the aging of animals.
This process leads to the formation of denser structures, what is in agreement with the bone densitometry data found in the literature.
