It was found that the re-sintered samples with better well-ordered layered structure, more perfect crystallization and more complete crystal structure will be formed with increasing temperature.
All these powders are layered oxide structure based on a hexagonal α-NaFeO2 structure (space group R-3m).
All these powders are characterized as a layered oxide structure based on a hexagonal α-NaFeO2 structure (space group R-3m).
The peaks split clearly, indicating the formation of a well-ordered layered structure, high crystallization and complete crystal structure.

Due to its great performance, it is widely used in the chemistry industry, petroleum industry, and so on.
Wan et al [11] developed a 3D fin structure for stainless steel packings by plowing/extruding.
This structure is the 2D-IEFT, as well as the basis for 3D-IEFT.
One low U-shaped groove is produced on the bulge between the fringes of the two grooves, forming such compound structure.
Based on the experiments, it is found that the rib structure varies as the rolling depth increases from 0.1mm to 0.85mm: the single trapezium rib appears first, then transforms to the compound rib structure gradually, and finally the single triangular rib.

These reactions change and toughen the structure of samples.
The porous structure was refined by growing products of pozzolana reaction.
The changes in the structure of samples were confirmed also by thermogravimetric analysis.
This method could help to specify better individual crystals in the structure.

Effects of γ- ray Irradiation on Structure and Properties of ZnO: Al Thin Film Wenwen Wang1,a, Tianmin Wang 1,b 1 Center of Material Physics and Chemistry, School of Science, BeiHang University a wangww1016@163.com , bwangtm@buaa.edu.cn Keywords: ZnO:Al (ZAO) thin film; γ-ray irradiation; positron annihilation; crystallinity; vacancy defects.
Meanwhile, most properties of ZAO thin film have dependencies on the defects in the structures.
In this paper, the dependencies of the structure, morphology and electrical properties of ZAO thin film on the dose in the range of 0 to 8x10 4 Gy and the rate of γ-ray irradiation are investigated.
X-ray diffraction (XRD) with a Cu Ka source was used to determine the crystalline structure of the samples and the surface morphologies were determined with a XL30 s-FEG Scanning Electron Microscope using secondary electrons.

In this paper, we present a simple solution-immersing method to prepare superhydrophobic structures on copper foils.
Fig. 1c shows the surface structure of the resulting copper foil at a bigger concentration of 1.5g/L.
To obtain more information about the formation of the grass-like structure, we also studied the influence of immersing time.
The Fig. 2 shows the surface structures on the copper foils which are immersed in stearic acid solution of 2 g/L at different time.

The results reveal that it is difficult to form a microcapsule structure from neat styrene (St).
Therefore, it is easier to form hollow structure because polymer microcapsules have a lower interface free energy per unit area.
Hollow structure then occurs.
The hollow structure could not be obtained.
It is difficult to form the hollow structure when only a single monomer-St was used.

UV and IR data confirmed commonly the characteristic absorption of citral chain and aromatic segments in molecular structures.
The introduction of methyl substituted groups into the present azobenzene segment was expected to lead to change of conjugated structures and new properties are expected.
The structures of these molecules were confirmed by 1H NMR.
Chemical structures and abbreviations of azobenzene derivatives.
In order to investigate the characteristic vibrations in molecular structures, we have measured the FT-IR spectra of both azobenzene derivatives in KBr plate, as shown in Fig. 3.

The SLS (Selective Laser Sintering, SLS) technology can directly manufacturing any complex structure, however, due to the limitation of the manufacturing engineering factor, the surface quality and the dimension accuracy of the green part are still an outstanding problem.
So, when the part structure is complicated, the important structure dimension should be chosen the orientation 0, 45, or 90 degree. 1 Introduction SLS involves selectively fusing particles of a powder bed using a laser beam which scans the surface and only fuses the powder on a given section [1, 2, 3, 4].
Fig. 1 The two-dimensional structure of the experimental sample: X1=100，Y1=100，Z1=15，X2=28，Y2=28，Z2=6，D3=40，X4=40，Y4=40，Z4=10，Z5=12，D5=40 2.2 The experimental process According to the five different part orientations, three samples with polystyrene (PS) polymer powder were fabricated for every part orientation.
When the part structure is complicated, we should keep important faces and edges in the section of 0, 45 and 90, it can maximum reduce the stair-stepping phenomenon and manufacture part with higher accuracy.
