As we know, chitosan has different structure in the different acid solution.
When acetic acid is used as solvent, the chitosan shows structure of TypeⅡ(the extended eight-fold helical structure with 40.8 Å axial repeat), which is benefit to chalet with metal ion[5].
But the TypeⅡstructure of chitosan was easy to collapse by heat treatment at high temperature, this collapsed structure hindered n-HA to enter into interior of chitosan.
So we think that the crystal of n-HA has a structure and crystal size similar to natural bone.

The chemical structure of the product obtained by the process of the present study was verified by IR and NMR.
NMR and IR confirmed the structures of the substances.

The structure of the intermediates, monomers and polymers were characterized with FTIR and 1HNMR measurement.
Compared with photoisomerization and photodegradation, photodimerization has more stable chemistry properties and bigger potential applications [3].
All the structures were confirmed by FT-IR and 1H-NMR spectroscopy.

Several kinds of structure defects for LPSed SiC were emphasized to discuss.
Some impurities vaporized and formed hole around by a halo (dark), which would affect the neighboring structure (Figure 4(e)).The defect in Figure 4 (f) is due to milling ununiformity of powder mixture of SiC and aid: it could cause the liquid ununiform gathering.
Some metal impurity, like Fe, is incompatible with components of SiC ceramic in physic- chemistry property.

Moreover, the analysis of the external view and the structure of Cu-Au nanoparticles of various chemical composition allowed us to conclude that a large number of binary nanoparticles were of an icosahedral structure.
The structure of particles with D = 2.0-20.0 nm was determined as fcc.
In the end, we can say that in all the experiments carried out, the most diverse structure of Cu-Au nanoparticles was observed without a clear understanding of exactly which structure and shape can be formed as a result of a particular synthesis method.
In addition, the analysis of the external view and the structure of Cu-Au nanoparticles of various chemical composition showed the following peculiar features: a big amount of binary nanoparticles had a pronounced icosahedral structure (Fig. 2).

Hydrothermal Synthesis and Luminescent Properties of BiPO4:Eu3+ Phosphors Sha Ren1,a*, Lina Guo1,b 1College of Chemistry and Environmental Science, Inner Mongolia Normal University, Hohhot 010022, China asr@imnu.edu.cn, b775735220@qq.com Keywords: BiPO4: Eu 3+, Luminescent properties, Hydrothermal method.
The structure and composition of the samples were characterized by IR and XRD.
The results showed that with the increase of hydrothermal temperature and hydrothermal time, the crystal structure of BiPO4 changed from hexagonal phase to monoclinic phase.
Different crystal structures of Eu3+ doped BiPO4 samples had the same emission peaks in emission spectra excited by blue light wavelength of 395nm.
The crystal structure changed from hexagonal phase to monoclinic phase when the hydrothermal time was increased from 2h to 10h at the temperature of 160ºC.

The effects of nitrogen doping level on the structure, optical, and electrical of the as-grown NCD:N was discussed.
The results showed that the micro structure, surface roughness, electrical properties, and optical properties were affected by the nitrogen doping.
In order to obtained Ohmic contact of Al/Si/NCD/Au multilayer structure, annealing procedures were carried out at 450 oC in Ar ambient.
Raman spectra for the NCD films grown in H2-4% CH4 chemistries with addition of N2 concentration ranged from 0% to 20%.
The as-prepared intrinsic diamond film possesses characteristic peaks of NCD includes 1140 cm-1 of C-H bond (polyacetylene, trans- structure), 1332 cm-1 of diamond phase carbon, 1350 and 1580 cm-1 of D and G band of sp2-structure carbon, respectively.

It has a tetragonal structure at room temperature and shows a cubic structure above the curie temperature.
The crystal phase and the structure of the PBT thin films were identified by using the X-ray diffraction method.
