The possible reasons for the special morphology of PAni are that the tubes structure of CNT are propitious to the dispersing of aniline monomer and the oligomers, and causes the PAni chains to be oriented.
The peaks around 1235 and 1304cm-1 represent the asymmetric C-N stretching and N-H bending vibrations of the polaron structure of PAni.
These peaks indicate the highly pronounced oscillation structure characteristics of protonated PAni.
The sensing performance of the PAni/CNT nanorods sensor could be attributed to the effective electron transfer between PAni and CNT and the increase in the specific surface area of nanorods structures.

The pure hexagonal structure of NiCoP bimetallic phosphides was confirmed according to JCPDS card no. 71-2336.
The finest fibrous structures for spinned NiCoP CF with an average diameter of 1 μm can be seen in SEM and TEM scans (Figs. 3a, b).
On the cross-section of SEM fibers, the porous fibrous structure is clearly visible (Fig. 3b).
The hexagonal structure of NiCoP nanoparticles with SG: P-62m (189) obtained by XRD investigation was validated by electron diffraction analysis.

In this study, the sintering temperature was successfully decreased,while the “core-shell” structure concerning on the X9R performance of the material was well preserved.We have also studied the effect of Bi content on the core-shell structure.
It is known that BKT can form solid solutions with BT because they share the same ABO3 type perovskite structure[14].
Thus, the A−O bonds are strengthened in the perovskite ABO3 structure by Ca2+ incorporation, whereas the Ti−O bonds are weakened.

We were
interested in the chemistry of the surface, therefore nitrogen or carbon ions were implanted.
The ratio of three point strength to the four point strength is shown in Fig. 4, these quantity contains information on the distribution of defect structure (see discussion).
Discussion The structure of implanted ceramics is rather complicated.
This time we can not pronounce more than the increase of ion energy damaged the structure.
Both quantities are monotonic functions of the density when the structure did not change during the given process [19, 20].

Because vulcanization under a temperature gradient produces a graded network structure, the obtained graded rubber will exhibit certain unique properties.
This refers to a permanent change in the microscopic structure, resulting in an increased hysteresis loss [19].
This is because of the gradient structure of graded rubber.

Unfortunately, many amorphous and agglomerate structures were seen through the scanning electron microscopy (SEM) images of the sample produced.
SEM image showed that CNTs produced were short, thick and the structure tends to agglomerate.
At high temperature conditions, banana peel activated carbon – mineral oil mixture was decomposed and formed the graphitic structure of carbon.
Difference structure of waste engine oil with another waste natural oil may cause this happened.

XRD results helped to characterize the crystal structure of activated carbon sample.
It indicates that P1 has apparent mesoporous structure and the aperture is mainly between 2 to 50 nm.
FT-IR FT-IR is useful to analyze the function groups and chemical structure of P1 qualitatively.
The other amorphous structure leads to the increase of lamellar gap and surface area of P1.
In addition, surface morphology of P1 is rough, showing an uneven and honeycomb structure.
