However, Sn-MSU-X exhibits highly ordered hexagonal-pores mesoporous structure.
This result clearly indicates that they all have the typical less long-rage ordered worm-like mesoporou structure[1].
Fig. 2 TEM images of the samples In order to characterize the porous structure of the samples, the nitrogen-adsorption measurement was utilized.
Among the three samples, the surface area and average pore diameter of Cr-MSU-X samples are highest(Table 1) Fig.3 The N2 sorption isotherms and pore size distribution of the samples Table 1 Pore structure properties of the samples Samples SBET(m2/g) Volume(cm3/g) Pore size(nm) Fe-MSU-X 603 0.68 4.9 Cr-MSU-X 676 0.61 5.8 Sn-MSU-X 638 0.57 3.5 SBET(m2/g)-BET surface area, Volume-Total pore volume, Pore size- Average pore diameter Unlike the noval synthesis of SBA series in acid conditions, Fe, Cr or Sn-MSU-X was synthesized under neutral pH condition by one-step hydrothermal synthesis.

After the yield point, the composites came into the plastic region, the model were not fit for evaluating the mechanical properties, the reason was that the inner structure of organic-inorganic hybrid composites are complicated, the numerical model used for simulation couldn’t mirror the response mechanism of the stress and the strain truly both the on materials aggregation structure level and molecular chain structure level.
Fig. 3 Comparison of stress experimented with the FEM simulated value for composites at low volume strain level 3.2 Simulation of tensile behavior based on micro-structure of composites The morphology and dispersion of the PP/1 wt. % TiO2 nanoparticles was observed using transmission electron microscopy (Fig. 4), Then an object-oriented finite element model (Fig. 5) with non-uniform particle distribution was constructed based on the image polished.

INTRODUCTION Crystalline aluminum hydroxide exists in five different crystalline structures, named after the mineral species: gibbsite, bayerite; nordstrandite; diaspore and boehmite.
The bundle arrangement allows the θ structure to be preserved above 1000 o C, while single fibrils favor the alpha structure formation at 1000o C.
CONCLUSIONS a) The method of drying of aqueous sols of fibrillar pseudoboehmite affects the structure of the aggregates forming the dried powders.

NHE range) ，only phenol-type structure can be oxidized and phenoxyl radical intermediates producted [8].
The structure of lignin macromolecules include phenol-type structural units (10% ~ 20%) and non-phenol-type structural units (80% ~ 90%) [9].
Many studies have shown that phenolic structure of lignin can be indirectly oxidized by the laccase under the condition of mediator existed.
Especially when there was the natural mediator, the radicals produced would continue to oxidize the non-phenolic structure of lignin, forming more chemical bindings and increasing the wet strength of paper or paper board.

Since the discovery of carbon nanotubes (CNTs) by Iijima in 1991[1], CNTs have received much attention for their many characteristics, such as unique structure, excellent mechanical properties, thermodynamic properties, conductive properties and high aspect ratio features, which has been as a typical one-dimensional material[2].
The injection conditions would affect the fluidity of MWCNTs/PC composites which leaded to changing the viscosity of the composites and forming the different internal subtle structures of MWCNTs/PC composites samples (three layers with different thickness) in injection molding.
The reason might be attributed to that the injection conditions affect the orientation of the nanocomposites and form different surface structures of MWCNTs/PC nanocomposites samples (formed three layers with different thickness) in injection molding.

Results Loss factor tan δ Ethylene-vinyl acetate due to the content of the polar vinyl acetate units in its structure refers to the polar rubbers.
A large number of polar side groups in the structure of this copolymer gives a high value of loss factor tan δ [5-7].

In this regard, there is a number of urgent scientific and technical problems associated with the choice of compositions of mixtures of powders, alloying substances, heat treatment modes in order to create a structure that provides increased physical and mechanical properties of materials.
Of scientific and practical interest is the use of nanopowders (TiN, Fe2O3,Y2O3, WC, TiC, SiC, VC, NbC, TiO2, Al2O3, MgO, ZrO2) to modify the structure of metals and their alloys with the aim of obtaining higher physical and mechanical properties of products [3,4,5,6,7,8].

A highly concentrated plasma energy provides a high temperature which facilitates the formation of a homogeneous structure inside the powder particles, thereby increasing their physical-and-mechanical properties [3, 4].
So, the valence band in the absorption spectrum in 1093.82 сm-1 maximum is characteristic to the Si–O–Si skeleton structure.
This is connected with the increase in the average distance of (Si, Al)–O and ordering of the skeleton structure due to its amorphization.
Aluminum oxide is the important component which makes a distinguished contribution to the formation of the microsphere structure.
