The results indicate that the heterojunction has smaller effects on the structure defect of CNTs [3].
Considering that the polyethylene has good flexibility and a simple physical structure, it is selected as the material of the polymer chain. 
This result is mainly because the structure defect at the interfaces leads to scattering during the phonon propagation process and the decrease of phonon mean free path.

The effect of K-doping on lattice structure, morphology and electrochemical characteristics of Li4Ti5O12 was investigated.
The crystal structure of the as-received samples was identified by X-ray powder diffraction analysis (XRD) with a Cu Kα radiation source (DX 2700).
Results and discussion The crystal structure and phase formation of the as-obtained samples were identified using their XRD pattern, which is discribed in Fig.1.
All the peaks can be well indexed on the basis of cubic spinel structure with a Fd-3m space group (PDF#49-0207).
This means that the low doping of K+ does not alter the structure of materials.

Introduction LnMnO3 (Ln = rare earth element) has a perovskite-type structure for Ln = La - Dy and a hexagonal structure for a smaller ionic size of rare earths [1].
In general LnMnO3 (Ln=La- Dy) with the perovskite-type structure belongs to an orthorhombic system near stoichiometric composition and this orthorhombic distortion is caused by the Jahn-Teller effect of trivalent Mn ion in the oxygen octahedral field in the crystal structure [7].

For the spin-coated composite film, the microphase separated structures of PS-b-P2VP BCs are not observed (not shown).
After annealing at 150 ºC for 36h, as shown in Fig 2a, microphase separated structures could be observed and the dark dots were randomly distributed in the film.
Upon annealing, the structure of the composite film will evolve to equilibrium gradually.
Hydrogen bonding interactions between P2VP and MUA molecules attached on Fe3O4 MNPs changes the interaction between P2VP and the substrate and finally leads to a change in the structure of the composite film.
The composite films may provide a powerful platform to investigate structure-property correlations and find potential applications in chemical sensors, biosensors, catalysts, chemical separation, etc.

Fig. 1 shows the tensile properties, of the base metal as also the welded structure using difference filler metal.
The yield for welded structure used ER5356 yield strength 200 Mpa and 235Mpa for ER4043.
Tensile strength of welded structure using ER4043 is 180 Mpa and for ER5356 is 190 Mpa.
Excess silicon is generally believed to be beneficial for increasing the ductility of the welded structure.

Optimization of Conditions for Extraction of Acid-soluble Al2O3 from Pyrophyllite JunJun Wu, HaiFeng Chen, ShiJiang Zhao and Bin Li Department of Chemistry, Huzhou Teachers College, Huzhou 313000, China shenlandeye@163.com Keywords: Acid-soluble; Al2O3; Fitting; Pyrophyllite Abstract.
At different temperatures after heat activation and structural changes was analysis, the amount of pyrophyllite dissolution of alumina deter-mined by titration under different conditions, to under-stand coordination structure of aluminum dissolution in acid condition.
As Fig. 1 showed, it showed pyrophyllite particle size of about hundreds of μm2 thin sheet (upper right corner of the small map to enlarge), which was similar to the results we expected, because pyrophyllite were 2:1 layered silicon salt compounds [7], layered crystal structure of two adjacent layers connected only van der Waals force, combined with weak, by a simple machining could cause a "thinning" "stripping" effect, so this time we 100 mesh of the sample, with such a structure, could lead to various types of anions and cations into the (thin) layer (intermolecular forces had been largely ineffective), the sample had a certain adsorption capacity.
From the SEM photograph of the whole, this structure the "thinning" "peel" effect and wide distribution, degree of depth, in order to take over the adsorption experiments laid the structural basis, taking into account the pyrophyllite in aqueous samples.
