All these changes are directly related to the structure of the calcium silicate hydrate phase.
Introduction Chemical attack is of concern for the integrity of concrete when the structure is exposed to an environment rich in deleterious substances [1].
Moreover, it is independent of the crystallinity of the system [14], thus, appropriate for assessing the structure of the largely amorphous C─S─H phase [15].

Results showed that the formaldehyde degradation efficiency reached 70.8% when the doping amount of V was 1%(mol), the calcining temperature was 700 ºC and pH was 3.5; It improved to 88.5% with 20g activated carbon as support and the 89W energy-saving lamp as light source; The formaldehyde degradation products were H2O and CO2; The specific surface area and pore distribution of TiO2 were analyzed by BET and its crystalline structure was analyzed by XRD，which indicated that mixture of anatase and rutile have large surface area and strong photocatalytic activity due to the V-doping.
The crystalline structure of the TiO2 was investigated using X-ray diffraction (XRD) (Y2000, Dandong,China).
It was also found that the miscellaneous peaks of V-TiO2 were significantly reduced, indicating that the integrity of crystal phase structure of V-doped TiO2 was better than pure TiO2.

The differences of superficial (about 10 nm) extracellular polymeric substances (EPS) composition of thermoacidophilic archaea Acidianus manzaensis YN-25 acclimated with different energy substrates (FeS2, CuFeS2, S0, FeSO4) were analyzed in situ for the first time by synchrotron radiation (SR) based carbon K-edge X-ray absorption near edge structure (XANES) spectroscopy.
Furthermore, most of the existing studies on the evolution in composition of superficial (about 10 nm) EPS have been based on separation and purification operations, which may lead to lose of components and change in structure of EPS [1,2].

The structure of grafting milk protein polyester fabric was studied by SEM, and the wearability was measured too.
In this study, the polyester fabric was grafted with milk protein by using a synthetic crosslinkage compound which has softening function, and the structure and wearability of polyester grafted milk protein were also studied.

The catalysts were characterized by FT-IR, XRD, SEM and pore structure parameters and evaluated for the oxidative desulfurization of model fuel using hydrogen peroxide as an oxidant.
Solution C was consisted of the aqueous solution of 0.111-1.002g CeCl3·7H2O (Aladdin Chemistry Co.Ltd., AR grade).
Pore structure parameters results were got through SA3100 type specific surface area and pore size analyzer produced by the United States Beckman Kurt company.
It indicates that the catalysts remain integrity Keggin structures after the formation of the composites.
The SEM images and the pore structure parameters for the catalysts are shown in Fig.3 and Table 1, respectively.

Step three: control of materials through the stamping die, or via closed-cell structure.
The fourth step: The hemispherical shell plates welded to form a layer of spherical pore layer structure.
As the new method proposed in this paper, preparation is more simple, lower cost, the special structure makes a higher intensity.

These unique characteristics have introduced their potential application in different fields such as chemistry, physics, diverse engineering, materials science, and reinforced composite structures [3].
Finally the chiral structure is acquired where (0° <θ < 30°) or (m ≠ n ≠ 0) [2].
Then, three most likely defects (Si-doping, carbon vacancy and perturbation) were introduced to the models corresponding to which a finite number of carbon atoms in the CNT structure were replaced by silicon, removed from the structure for different amounts and dislocated from their original location in 3D space for different percentage of the length of the C-C bond, respectively [2].
Figure 1 illustrates perfect and defective forms of CNT structures.
This means that the defects in the structure of the SWCNTs cause a reduction in their vibrational stability and sooner resonance phenomena and vibrational instability will occur.

Materials and Methods Figure 1 The structure of model C2H4···2HX(X=Cl) As the interaction of C2H4 and 2HX(X=F, Cl, Br, I) is a weak interaction,requiring a higher accuracy of calculation, so, we using the MP2 method to study the interaction of C2H4 and 2HX(X=F,Cl,Br,I).
Specifically:use cc-pVTZ basis set for complex geometric structure optimization, then use the aug-cc-pVTZ basis set and apply a balanced correction method to calculate the binding energy of composite system in the optimization and calculation of the heavy elements Br,I valence electrons with the same level of basis functions.
Table 1 complex geometry can be seen: with the halogen elements in increasing atomic number,RC-C, RH-C bond length of the C2H4···2HX(X=F,Cl,Br,I) complexes is almost unchanged, indicating the formation of complexes C2H4···2HX in little effect on the structure of ethylene;and RH-X, R(X)H-π, RX···π in the C2H4···2HX complexes increasing greatly, indicating the formation of X-H···π hydrogen bond structure of halogenated greater impact;the X-H···π interaction weakened,as RI-H···π>RBr-H···π>RCl-H···π>RF-H···π, shows C2H4 and 2HX(X=F,Cl,Br,I) interact to form the X-H···π bond length periodicity changes,the π bond distance increases and less relevant interactions.All of X-H(X=F,Cl,Br,I) bond in the C2H4···2HX complexes point to the π electron center in a straight line,2HX molecule vertical point to the π bond,all the X-H···π bonds in the C2H4···2HX complexes have shown T-Shape stable structures.
