The X-ray diffraction patterns were analyzed by means of the MAUD program using Rietveld whole profile fitting to determine the crystal structure and lattice parameters.
The patterns of pure Fe3O4, TiO2 and CuO nanoparticles were marked and all peaks can be indexed as the typical cubic spinel, anatase structure and monoclinic, respectively.

A Philips PW 1710 X-ray powder diffraction spectrometer with copper anticathode (λ=0.154178 nm) operating at 40 kV and 30 mA was used to estimate the fraction of amorphous structure.
Second diffuse peak in the 33-45º range with a maximum at 0.256 nm shows the presence of amorphous structure compounds formed in the process of precursor synthesis [9].
Therefore, by adding the precipitation agent drop-by-drop into the first stage of synthesis highly developed porous structure was formed.

Amide had three existing forms, which were primary-amide, secondary-amide and tertiary-amide, whose structure forms were RCONH2, R-CO-NHR’ and R-CO-NR’R’, respectively [12].

First, compared to CZT, the bond ionicity of CMT is higher, entailing a greater tendency for crystallization into a hexagonal structure, but not in the expected zinc-blende structure.
Magniudes of g-factor, the superhyperfine structure area and the width of individual superhyperfine structure lines for second peak were determined as g= 2.007, A≈ 65.5 G and ~22.1 G, respectievly.

In the calculations, the trigonal field parameters  and ' are determined from the superposition model and the local structures of Ni2+ in the halides.
Up to now, however, the above EPR experimental results have not been theoretically interpreted, and the local structure properties around Ni2+ in these materials have not been analyzed, either.

The insoluble solid is transformed to Si3N4 and BN amorphous structures with an approximately 95% ceramic yield after being pyrolyzed to 1000˚C.
The chemical structure of PBSZ precursor was also confirmed by 1H NMR spectra, which was shown in Fig. 2.
The resonance at 4.7ppm was attributed to SiH2, and 4.3 ppm was attributed to SiH3 due to rearrangement of polymer structure. 11B and 29Si NMR spectrum were also used to further confirm the structure of PBSZ precursor.
It could be clearly seen that the structure of cured PBSZ after pyrolysis was particularly compact and without any defect.
Besides, the cured PBSZ could maintain the stability of its structure during ceramic reaction and exhibited excellent properties of ceramic conversion.

For example, with the same overall molecular weight a linear polymer has, hyperbranched polymers possess a significantly lower viscosity, thereby, as a novel pathway to enhance synthetic polymer functions in the fields of coatings, drug delivery systems, supramolecular chemistry, nanotechnology, etc [1-2].
The HBPS-1 molecules with a globular structure, which have a lower contacting surface area, may cause a disruption or change in the surface interaction, creating less overall adhesion.
In other words, such a globular structure may possibly induce the occurrence of slip.
One factor is the HBPS-1 has a globular shape structure with a highly branched and the absence of chain entanglements between the HBPS-1.
Another factor is that HBPS-1 has much lower intrinsic viscosities than PC, due to their relatively lower molecular weights and denser structures when compared with PC.
