Attenuated total reflectance infrared spectroscopic (ATR-IR) technique was used to characterize the structure of the hybrid films.
The chemical structure of obtained network affects morphology of the coating.
The hybrid systems have a unit form structure and the inorganic phases were in the nanosize scale, Introduction Nanocomposite coating films on glass substrates are important for applications such as window glass, mirrors, and windshields of automobiles, and so on [1] and [2].
Another factor affecting the hydrophilic property is the chemical structure of the surfaces.

The crystal structure and composition, electrical conductivity, optical rotation, dielectric loss and magnetic loss of the as-prepared samples were researched.
It was also discovered that chiral material with good conductivity due to its unique structure and properties has shown a higher microwave absorption performance[4].
Results and discussion Structure andcomposition.
The FT-IR spectra of CFO confirms that the absorption peaksof570 cm-1and 416 cm-1belong to the spinel structure.

The results showed that the XRD pattern of the La-C-co-doped NaTaO3 was found to be crystalline phase with orthorhombic structure.
Thus, anion and cation doping can adjust the band structure of semiconductors, and it can also have an impact on the particle size and surface structure of materials [13], which usually results in a better photocatalytic activity [14].

Synthesis of Highly Mono-dispersed Mesoporous Silica Spheres Guiru Zhu1, a, Li Wang1, b, Duo Wang1, c, Congjie Gao1, d 1Key Laboratory of Marine Chemistry Theory and Technology, Ministry of Education, College of Chemistry and Chemical Engineering, Ocean University of China, Qingdao 266100, China azhugr@ouc.edu.cn, b wangli19841123@163.com, cwangduo@ouc.edu.cn, d gaocjie@mail.hz.zj.cn, Keywords: Mesoporous silica; Sphere; Mono-dispersed Abstract.
The results showed that the synthesized mono-dispersed spherical silica particles have ordered hexagonal mesoporous structure, high specific surface area and uniform pore size distribution.
The XRD patterns of the materials synthesized with similar methanol ratio and temperature are almost same, suggesting that the concentration of C16TAC (Fig. 5-A) and TEOS (Fig. 5-B) have little influence on the orderity of the mesoporous structure.
It indicated that the influence of the amount of methanol on the mesoporous structure is weak.
It is assumed that parallel alignment of surfactants at the surface of the particles leads to a radially aligned mesoporous structure [17].

The phase structures are characterized by X-ray diffraction (XRD).
The possible reasons responsible for the quick fading of capacity are generally believed to the Jahn-Teller distortion of the cubic spinel structure of LiMn2O4.
With increasing Mn3+ in the structure, Mn3+ was gradually dissolved to electrolyte via disproportionation reaction, and the organic solvent was decomposed at higher potentials [4].
It is well known that LiMn2O4 takes the face-centered cubic framework of spinel structure with Fd3m space group, in which the Li+ ions occupy the tetrahedral 8a sites, while the Mn3+, Mn4+ (and the doping Ni3+) ions reside at the octahedral 16d sites, and the O2− ions are located at the 32e sites [16].

The additions of TiO2 shift the structure of YBCO system from rhombic to tetragonal structure.
This resulted in a large percentage of tetragonal structure in the YBCO system.
From the XRD the dominant phase was YBCO with orthorhombic crystal structure.

Characterized the crystal structures of these materials by diffraction of X-ray and mechanical behavior using tensile test.
The technique of X-ray diffraction was used as a tool to verify the phases that are present in the alloy steel submitted appropriate crystal structures.
Although aimed at the control of the austenitic phase in the steel structure, the use of this element is inappropriate for steels with orthopedic purposes.
Ultimately, stainless steel studied in this work showed off the chemistry which was established by the standard reference composition.
The diffractogram shown in Figure 1 shows the crystal structure of the stainless steel alloy studied in this work.

The situ method (also known as activated swelling method) can prepares monodisperse superparamagnetic microspheres with a mixed structure.

Analysis results through XRD showed that an orthorhombic structure of calcium ferrite NPs was observed.
The structure, the physical and magnetic properties of the synthesized nanoparticles have been analyzed.
The XRD result confirms the orthorhombic structure with crystal size of approximately 16.8 nm.

The global flame structure of flame and flow field were investigated at the fixed power output of 6 kW.
Spray flame involves the complex interaction of air, fuel and chemistry.
Understanding spray flame requires detailed investigation of the spray droplets, flow field, chemistry reaction, flame structure and the interactions between these factors.
This paper focuses on the global flame structure within the combustor.
Flame imaging technique is employed to study the flame structure.
