Abstract.
It is well known that electric field has an appreciable effect on the structure of water cluster [7].
Therefore, we have undertaken an abinitio electronic structure investigation of water clusters in a constrained polar environment mimicked by an electric fileld.
We therefore focused on generic trends of water structure change due to hydrogen bond changes in the presence of external electric fields.

The crystal structure of the prepared particles was analyzed by XRD.
On the other hand, particles prepared by calcination of melamine in a semi-closed space were found to have the crystal structure of g-C3N4. g-C3N4/MP-ST(1) kept the crystal structure of g-C3N4 and anatase and had the same crystal structure as g-C3N4/MP-ST(N), which was not hydrothermally synthesized.
This suggests that hydrothermal synthesis does not affect the crystal structure itself.
The surface structure of the prepared particles was analyzed by SEM.
It was observed to have a bulk structure with a size larger than 5 µm.

Abstract: Fundamental and applied research depends on the removal of organic toxic effluents from textile industries.
XRD data indicated the formation of monoclinic and hexagonal crystallite structures for CuO and NiO respectively.
CuO nanoparticles (NPs) are transition metal oxide of monoclinic structure, good photovoltaic properties and good thermal conductivity, these affects CuO NPs to behave as active photocatalyst.
By the data obtained, indicated that the formation of monoclinic and hexagonal crystallite structures for CuO and NiO respectively.

Keywords: HA, SBF, characterization, synthesis
Abstract.
The experimental results showed that the HA synthesized by the SBF route might be more close to that human bone in structure and compositions.
The powders were observed to be nano-whisker shape, containing trace amount of CO32, Cl- , Na +, Mg 2+ and K + impurities, which might be more close to that human bone in structure and compositions and might become a promising material for reinforcing ceramic in the biomedical field.

Abstract.
For high power density diesel engine operating characteristics and its unique compact structure, the development of new high power density diesel engine oil referred to the latest diesel engine oil standard GB 11122-2006.
In addition, we hope that high power density diesel engine make smaller size and compact structure, one of the important measures is to use the crankcase of useless space to lay sump, oil pump, oil heat exchangers, oil filter and oil road [3].

Accordingly, the predicted texture evolution depends on temperature, strain rate,
chemistry (solute level, particle number and size), and grain size.
With the obtained parameters, the flow curves of any processing conditions and materials chemistry can be derived.
Some orientations develop sharp band like structures (cell block boundaries), e.g. in β-fiber grains, but other orientations generate more equiaxed structures, e.g.
These structures are related to the activated slip systems [26,33-35].
However, more diffuse cell structures recover faster than sharp band like structures.

However, combination of these powders in layered structure, may offer advantages over the individual powders.
In this case, mechanical properties of the resulting layered structure can be improved.
No large cavity or other irregular structure is observed.
Coatings produced from both powders formed lamellar structures with the porosity of the order of 3%.

Abstract.
In addition, it is worth mentioning that calculation would have been more accurate had the structures been relaxed.
This is due to the fact that in the Li4C12 structure,two adjacent lithium atoms are at z = 0 and the other two adjacent are at z = 1.23 ˚A (see Figure 4c).
The visualizations of structures were performed using XCrySDen [10] for which the authors would like to thank Anton Kokalj.
The structure files for CNTs were generated using TubeGen online [11] for which the authors would like to thank J.

Therefore,
corrosion protection for the steel structures is necessary to guarantee the safety of them.
The chemical structure of reagents is showed in table 1.

The degree decrease of the shear strength is only 6.3%, which almost depends on mechanism lock pin structure at the interface of the coating.
