Investigating the interaction mechanism of gold nanoparticles with mercapto amino acids Huiqing LI, Xiufang WANG, Jun ZHANG, Xiaowei DI* College of Chemistry and Chemical Engineering, Inner Mongolia University, Huhhot.
We choose cysteine as model molecule because in the cysteine molecule structure there is mercapto group –SH , which can form covalent bond to the gold nanoparticles[19-21].

This change in the chemistry of the oceans was quantifiable and predictable.
From basic marine carbonate chemistry, it is well known that as atmospheric CO2 increase, surface-ocean pCO2 will increase, reducing ocean pH and [CO32-].
The increasing of the volume fraction of atmospheric carbon dioxide would lead to the acidification of seawater and ocean acidification would impact the process of the carbon chemistry of different waters in different degrees [6].
This structure could easily be dissolved in unsaturated carbonate ion environment [7].

Introduction A large number of studies on micro-phase structure and mechanical properties of materials gave a way to get the satisfactory materials via controlling the structures of materials.
PEI-Siloxane Copolymer Fig. 1 Chemical structure of the thermoplastic modifier, PEI-Siloxane Sample preparation.
From the onset structures (micro-bicontinuous phase structures) of the phase separation, we find that the phase separations occur for all the samples and the varying content of PEI-Siloxane in the systems has little influence on the formation of the onset phase structure.

A general method of selecting cooling stave material and structure design for longevity design of cooling stave was developed.
Preprocessor The structure of cooling stave is shown in Fig.1.
The geometry model was built according to actual size and actual structure of some domestic blast furnaces in iron-making plant with seldom simplification.
Fig.1 The structure of cooling stave Fig.2 Model of water pipe distribution 8-node hexahedron element (SOLID70) was used in the element division of the furnace wall for the software ANSYS, stove outer covering and cooling stave.
It can be seen that, from Fig.4, the temperature range of the furnace lining was in 247-1003 oC, because the temperature of some furnace linings was far higher than the chemistry corrosion temperature 570 oC, cooling stave can only delay the damage of furnace lining, and can not prevent emergence from chemistry corrosion.

ZnO nanocrystals possess noncentrosymmetric structure that used as non-resonant nonlinear investigations for both in-vitro and in-vivo biomedical applications.
The structure of the ZnO nanocrystals were scanned using ITALSTRUCTURE ADP200 X-ray diffractometer, equipped with graphite monochromatized CuKα radiation (λ=1.5405Å).
The intensity of 002 peaks is obviously lower than 100 and 101 peaks, which protects this idea that the ZnO nanocrystals have a hexagonal wurtzite structure [15].
The XRD spectroscopy of ZnO nanocrystals shows that the ZnO nanocrystal has a hexagonal wurtzite structure.

Our results show that the obtained Ca(MoO4)x(WO4)(1-x)microcrystallines are single-phase scheelite structure with tetragonal symmetry.
Ltd Chemistry Branch) were used as the starting materials.
The FT-IR results also confirm that the obtained that the prepared Ca(MoO4)x(WO4)(1-x) microcrystallines possess single-phase scheelite structure.
These phenomena probably are owing to the lack of any stabilizing surfactants and the grains are self-assembly hierarchical structures [9].
The microcrystallines possess a scheelite structure with tetragonal symmetry.
