Though the melting point and hardness of aluminium and its alloys are lower, their oxide and nitride have properties of higher melting point, hardness, and chemistry stability, which are used to be protective layer of a varieties of materials.

Raman spectra of SrTiO3 prepared by direct current arc discharge plasma process Shuangbin Li1,2, a, YingYao1,b, Yongzhong Jia1,c, Jing Yan1,d,Shaolei Xie1,e 1 Key Laboratory of Salt Lake Resources and Chemistry, Qinghai Institute of Salt Lakes, Chinese Academy of Sciences, 810008, Xining, China. 2 University of Chinese Academy of Sciences, 100049, Beijing, China.
In order to understanding these properties, the lattice dynamics, structure and phase transitions have been investigated.SrTiO3 is known to have the ideal cubic perovskite structure above 110K, Space Group Oh1, where five ions per unit cell are located at centers of symmetry.
Upon cooling, the cubic structure undergoes a phase transition to a tetragonal structure.
The structure of these powders was studied by X-ray Powder Diffractometer (XRD, Xpert Pro, PANalytical) at the room temperature.
However, Raman spctrum is quite sensitive to the changing crystal structure.

The main components of rosin, resinolic acids, have hydrophobic phenanthrene structure.
Characterization of product The structure of product was characterized by FTIR, UV and TLC.

Cold cracking is caused by a combination of the following factors [2, 4], such as high levels of diffusible hydrogen in the weld line; a brittle structure in the heat affected zone and a significant tensile stress concentrations, in the welded joint.
Based on the conclusions from this analysis for pipes with wall thickness larger than 6 mm, it was necessary to design a new chemistry and the modification of some thermo-mechanical rolling parameters (trial 2) in order to improve the toughness.
The reason why the addition of Ti in a concentration up to 0.017% is due to its effect of structure refining by suppressing coarsening of austenite grains as a result of the formation of titanium nitride [3,4].
The severe decrease of toughness KV, even under admitted limit, for some pipes as 193.7´8 mm and 219.1´10 mm, is mainly caused by a defective metallurgical structure, as observed in Fig. 5, generated by an inadequate thermo-mechanical rolling process.
The new chemistry and results obtained are shown on Table 3.

America), Dicumyl peroxide (DCP) (Shanghai Chemical Co., China), Roasting Fe2O3: Fabricated in our lab, Liquid olefin (Zhenhai Institute of Applied Chemistry, China).
Main-chain is saturated structure and the oil is saturates, because of the structures of main- chain and oil are similar, EPDM can adsorb oil.
Roasting Fe2O3 could reduce some intermolecular interaction of polymer chains and form many channels in the network structure, and the oil molecule could carry into the network structure easily and increase the cubage in network structure.
EPDM was cross linked with DCP; a network structure was formed in EPDM.
The oil molecule can come into the network structure easily.

The results indicate that the ZnTe nanocrystals were crystallized in cubic zincblende structure and their morphologies and sizes are polyhedron and diversified, respectively.
It is necessary to understand their structures and the change in their properties.
Raman spectroscopy has become one of the preferred choices to characterize and investigate the structures and properties of nanomaterials [4].
Results and Discussions The crystal structure of ZnTe crystals.
Simultaneously, the diffraction peaks confirm ZnTe to be cubic zincblende structure [5].

Rheological properties of rice protein-dextran composite system Xianghong Lia, Yongle Liub, Li Nac School of Chemistry and Biology Engineering, Changsha University of Science & Technology, Changsha, Hunan, 410004, China a xianghongl@163.com, b lyle19@163.com, c na182007@163.com Keywords: Rice protein, Dextran, composite system, rheological properties Abstract.
The formation of gel network-like structure appeared to have occurred through the interaction of rice protein and dextran at certain biopolymer concentration.
Some food scientists made use of the interaction of polysaccharide and protein to obtain this kind of network-like structure [5], and a proper understanding and control of these interactions should enable to design products with desired structure and texture [6].
Only 15 %rice protein/8% dextran mixture did form gel network structure.
Furthermore, mechanical properties provide information about network structure.

The Mn-doping promotes the formation of the single phase compounds with more ordered structure.
New layered structure compounds LiNi1− x− yCoyMnxO2 and LiNixCo1-2xMnxO2 have been developed which demonstrate the better overall performance [8-10].
The Miller indices of all the samples are based on the hexagonal α-NaFeO2 structure (space group: R-3m, no. 166).
The larger I003/I104 value implies that the better ordering structure exists in the sample [15].

From the processing parameters and fiber properties change analytical chemistry swelling pulp processing performance improvement. 3.1Acidic zinc chloride and alkaline hydrogen peroxide bleaching synergistic effect of swelling Hydrogen peroxide treatment is in the Alkaline condition，the fiber occurs alkaline swelling in the role of the alkali, the DSC of APMP pulp after peroxide bleaching is 0.18%; zinc chloride is under acidic conditions.
As can be seen from the figure, the acid chloride treated fiber volume becomes large, the structure is much more loose.
Cellulose include crystalline and amorphous region, their physical and chemical properties are closely related with the arrangement of cellulose molecules, generally, amorphous has loose structure and strong reaction[5].
Zinc chloride implemented fiber swelling by breaking hydrogen bonds in cellulose structure, zinc play easily the role of the amorphous region, which make the distance between the cellulose molecular chain increasing and causing fiber distortion.
Crystalline structure is dense, it is relatively difficult to deal with low concentration of zinc ions.

Although three-dimensional structures are formed in the mixing processes as the local Reynolds number increases, the two-dimensional structures continue to persist even at a high speed [3].
Pickett and Ghandhi [5] investigated experimentally the structure of a reacting hydrocarbon-air planar mixing layer, and found the inlet stream conditions affected the chemistry did not appear to cause significant changes in the overall mixing layer structure.
The purpose of this study is mainly to simulate the supersonic mixing layer and to examine the effects of reaction and convective Mach number flows on the structure of a spatial evolving supersonic mixing layer.
The mixing layer consists of large-scale structures which grow linearly with the increasing distance.
The effects of the increased pressure of two inflow streams on the reacting mixing layer structure are also investigated numerically.
