Material Structure and Mathematical Model The three-layered structure of the investigated material is schematically shown in Fig.1.
The structure of the “composite” PET thin film in this research may act as functional layers in a more complicated composite structure which can greatly enhance the anti-corrosion properties as well as anti-permeation properties [5].
The “composite” structure in Fig.1 means that the mechanical behaviors of such a material shall come from the contribution of both materials (aluminum and PET), and shall depend on the structure as well.
Using Eq.1 the secant Young’s modulus of the “composite” structure is calculated to be around 10.0 GPa.

The morphology, structure and chemistry of the oxide products formed on the oxidized samples were examined by means of XRD (Philips X'Pert Pro) and SEM-EDS (JEOL JSM-5400) analysis.
In the case of uncoated steel oxidized in the Ar-H2-H2O gas mixture, the main oxidation product was a thin chromia layer in the form of ridges due to the influence of hydrogen on the defect structure in chromia scale [9].
The TEM investigations showed that this film contains grains of spherical shape of about 350-1600 nm in diameter with an orthorhombic structure, as confirmed by SAD analysis.
The cross-sectional SEM-EDS investigations of the Fe-25Cr steel coated with the above mentioned films after oxidation in different atmospheres revealed that the reaction zone at the metal/substrate interface may have a multilayer structure, depending on the coating material.

It has stimulated a strong interest in the application of MOFs in the clean energy neighborhood.[2] MOFs combines the strength of metals with the chemistry of organic materials and is a perfect combination of inorganic chemistry and organic chemistry.
Structure of MOFs.
The structure of MOF-801 belongs to the cubic space group.
Principle and Structure.
The structure of the device is shown in figure 5 below.

The supercell structures used in the calculations were constructed from 16-atoms (8Fe, 8Al) of the B2- FeAl structure.
The B2-structure is defined as the α-sublattice of Fe atoms and β-sublattice of Al atoms, like the cubic CsCl-structure (space-group symmetry is Pm-3m (221)).
The value obtained for the B2-FeAl structure without defects is 39.74 states/Ry.

The hydrothermal synthesis and photocatalysis of TiO2 powders Li ming Jiang Chemistry Center, Harbin University of Commerce, Harbin 150076,China Jlm.032349@yahoo.com.cn Key words: titania; hydrothermal synthesis; photocatalysis Abstract: Titania powders were prepared under hydrothermal conditions by employing organic molecule β-cyclodextrin(CD) as template, and characterized by means of TGA, XRD, BET .
The results showed that titania powders were anatase structure;the titania powders with specific surface area up to 216.2 m2g-1 were prepared while the system pH was about 1 , and the powders had the best photocatalytic activity.
Introduction In recent years, TiO2 materials with high specific surface area due to the developed pore structure, adjustable pore size within a certain range, easy modification of material structure , are widely used in the field of photocatalysis and photoelectric conversion.
First of all, the β-CD assembled with hydrogen bonds, and then hydrogen and hydroxyl which were original from the hydrolysis of inorganic phase formed porous structure .
XRD results showed that the samples TiO2 powder with anatase structure was successfully obtained.TGA results showed that β-cyclodextrin can be completely removed under calcined at 350 ℃ for 4 h.

This property is likely to be adequate to permit distinction from dentin and adjacent anatomical structures.
