From figure 1, it can be seen that the surface of SnO2 films with different number of layers supported on carbon fiber all exhibited porous structure, and it tended to be more uniformity and density with the increase of number of layers.
It can be found that only elements of carbon, oxygen and tin were exhibited on the surface of sample, carbon was derived from carbon fiber, and the number ratio of oxygen and tin was 0.5 almost according to the theoretical value.
It can be found that typical anatase TiO2 was generated with anneal at 600 oC referring to the standard crystal card of CPDS NO.21-1272.
Referring to the standard crystal card of JCPDS NO.41-1445, the diffraction peak of SnO2 annealed at 200 oC is amorphous, while rutile SnO2 was obtained annealed at 600 oC which suggest that anneal in nitrogen will play a role to the transformation of crystal.
Photocatalytic activity of TiO2/SnO2/CF The testing sample was put in the tube containing with 25 ml methyl orange of 80 mg/L to characterize the catalytic property, and the testing number is five for each material.

Review of the literature suggests that the interactioin of the reactive plasma species with TPS material is expressed in terms of recombination coefficent which is defined as the ratio of the number of recombined atoms to the total number of atoms impinging on the surface.
Comparison of JCPDS data of iron oxide (JCPDS card No. 85-1436) with that of experimentally observed pattern confirms the presence of transition element doped Fe3O4 phase.

Among these, a number of activities have been carried out on the investigation of the optical properties of lanthanum magnesium hexaaluminate (LaMgAl11O19, LMA) which has a distorted magnetoplumbite structure and consists of spinal-like blocks separated by mirror planes [3, 4].
It presents that the diffraction peaks of the powders in the XRD pattern matches well with the standard PDF card of the LaMgAl11O19 [JCPDS 78-1854].

The corresponding EDX analysis confirming the existence of all elements involved in sample The XRD spectra which is presented in figure 3 reveals that the nanoflakes are single crystalline and can be marked as cubic-phase (a = 0.421nm) MgO (JCPDS card 45-0946).
The method has several unique advantages and the product will find number of applications.

The intensities and positions of the peaks are in good agreement with JCPDS card (No. 45-0937).
Fig. 2 SEM images of CuO synthesized under the different conditions by the hydrothermal method (a-1 m mol CuCl2 + 2 m mol Na2CO3, 180 °C, 24 h; b-1 m mol CuCl2 + 2 m mol Na2CO3, 180 °C, 48 h; c-1 m mol CuCl2 + 2 m mol Na2CO3, 240 °C, 24 h and d-1 m mol CuCl2 + 3 m mol Na2CO3, 240°C, 24 h) A large number of CuO flakes agglomerates are shown in Fig. 2(a).

The measured ionic transference number of 0.65 indicated substantial electronic conductivity.
For x=0.2, all peaks correspond to LaAlO3 with a perovskite structure (JCPDS card 31-0022) appear.

The inorganic phase of bone is carbonated hydroxyapatite (CHA), and the organic matrix is mainly collagen type I[6]. therefore a large number of researchers has been worked on collagen, and on its derivative, gelatin.
Chitosan (85% DD medium molecular weight and product number of 448877)was provided from Aldrich-Sigma Co.
These diffraction patterns were compared with calcium phosphate compounds cards present in ICDD database and the phases present in each sample were indexed.
These peaks are indicative of hydrogel matrix and brushite (CaHPO4•2H2O) (JCPDS # 2-0085) precipitates that have amorphous or semi-crystalline nature.
The diffraction pattern of samples incubated in SBF solution reveals sharp peaks that are mainly related to the presence of Hydroxyapatite (JCPDS # 09-432), as well as the crystalline nature of the precipitates.

The lattice constant values were compared with values reported in JCPDS cards [6].
Where 8 represents the number of molecules in a unit cell of spinal lattice, M is the molecular weight of the sample, "a" is the lattice constant and N is the Avogadro's number.

This can result in inaccuracies in estimating tie-line compositions for these phases because of errors in extrapolating inadequate number of data points.

All strong intensity peaks of sample A, C, D could be indexed to orthorhombic MoO3 (JCPDS card No. 76-1003).
It can be clearly seen that the spheric-like flowers are composed of large numbers of curly flakes with nano-size.
