Influencing on the wall thickness of deep cavity injection molding shell Liyun Yang 1, a, Jiamin Zhang 2, b 1Department of Chemistry and Chemical Engineering, Xinxiang University, Xinxiang, Henan, 453003, China 2School of Chemistry & Chemical Engineering, Henan Institute of Science and Technology, Xinxiang, Henan, 453003, China a liyunyang2007@126.com, bzjm@hist.edu.cn Keywords: Deep cavity shell, The wall thickness, Injection molding Abstract.
The quality question of deep cavity shell was the wall thickness, its influence factors, together with the product structure, die-structure, technology and other factors.
To the battery shell, we can change the structure of the combined shell through change the size of the plate.
According to the characteristics of the shell structure, the mold stripping process should adopt the push plate stripping process.
Mold structure design The shape of the mold gate shown in figure 1, the mold use the eccentric gate, it consists of the diagonal nozzle and location ring.

Printability of coated paper can be well related with coating pore structure.
Large pore diameters and small pore volume of coating layer structure can improve print gloss.
Pore structure of low-gloss coated paper and the relationship between print properties and pore structure were analyzed by mercury intrusion porosimetry in this paper.
The pore structure characterization and its effect on printability were discussed.

Sb and P-doped ferromagnetic properties [19], Cu-doped passivated structure[20], Cr-doped ferromagnetic characterization[21] and Hg-doped bulk structure carrier concentration[22] are experimental studies.
Theory Density functional theory (DFT) is a quantum mechanical modelling method used in physics and chemistry to investigate the electronic structure principally the ground state of many-body systems.
DFT is among the most popular and versatile methods available in condensed-matter physics, computational physics and chemistry.
For the bulk heterostructure, one semiconductor bulk structure was used along the z-axis.
Potential curves of BP/GaN [32] and Te-BP/GaN structures are given in Fig. 2.

The Polymorph structures of bismuth oxide (Bi2O3) have been depends on the temperature.
The materials' nanocrystalline structure was suggested by the large reflection peaks.
Using the least amount of solvent and under normal conditions, a mechano-chemistry pathway was used to produce nanostructured Ag-Bi alloys.

Study of an Inorganic Ion Exchanger Al1.25Fe0.75(PO4)2 Jinhe Jiang MicroScale Science Institute , Department of Chemistry and Chemical Engineering ,Weifang University, Weifang, 261061,China Corresponding author.
Chemical composition, structure and some related properties and complex mechanism of this ion exchanger are investigated by electron microscopic, X-ray diffraction and chemical methods.
In this paper, the solid state reaction crystallization method was used to synthesize the Al1.25Fe0.75(PO4)2 of spinel-type oxide, whose composition and structure are different from those in literature [3-4], and the property of its ion exchange selective to Li+ was studied.
The structure of compound metal oxide Al1.25Fe0.75(PO4)2 crystallized at 720°C was much perfect.

FTIR, NMR and SEM were used to characterize the structure and surface morphology of the product.
FTIR spectroscopy was used to verify the change in the chemical structures of starch molecules caused by acetylation.
Based on these SEM photos, we found that beaded fibers were formed at low DS during electrospinning, and as the DS of the starch acetate increased, beaded structure disappeared gradually.

The alloy structure is of change with Mo-content increase.
The components of the deposits were measured using analytical chemistry of the titration method (Analytical Chemistry).
So that in the process of formation alloy structure the atoms formed complex space structure under the force of outer high speed revolving electron.
Electron diffraction patterns showed that the stronger bright spots of a lattice structure was the face-centered cubic structure, which was consistent with the formation of NiMo space lattice structure, the weaker spots and the lattice of bright spots formed a fuzzy and closed circle, from fig.1 and the analysis of phase showed that the same complex structure were formed, so it can not judged the lattice structure of the alloy by the existence of the diffraction spots, but it indicate that the structure was the mixed phases of amorphous and nanocrystal.

Preparation and Characterization of NiO Nanoarrays with Different Hierarchical Porous Structure HaiYan Wu, XiaoLi Zhang, FengYun Su, TingTing Liu, and XiuCheng Zheng*,a College of Chemistry and Molecular Engineering, Zhengzhou University, Zhengzhou 450001, China azhxch@zzu.edu.cn Keywords: Nickel oxide; Mesoporous structure; Hard-template SBA-15.
NiO nanoarrays with different hierarchical porous structures were synthesized by using hard-template SBA-15.
The results will be helpful for the insight of the how the porous structure determines the capacitive behavior. 2.
The results reveal that the replicating template process does not change the cryatal structure of NiO.
