The structure of the phase transformation of Al2O3 was determined by powder X-ray diffraction(XRD) using CuKα radiation (λ=1.5406Å), Bruker D8 Focus instrument.
The α-Al2O3 crystalline structure is hexagonal close packing of oxygen while the structure of the other phases except for α phase is tetragonal distorted spinel [7].
This structure has an effect on XRD patterns with differences of intensity result from phase transformation.
Also, this crystalline structure was caused γAl2O3 has many vacancies on surface so it used to catalyst of catalyst support widely to have unique specific surface area.

As an attractive electrode material, graphene has special structures that make it own the corresponding property which shows great potential to prepare biosensors and apply in energy storage.
Due to its unique circular tube structure, CNTs are often seen as an ideal material to polymerize or composite with other materials, such as metal oxide, nano particles and other carbon materials, which leads to new materials applied in scientific research.
That is because graphene can easily twist during the process of dispersion, which could block the advantages of its unique structures.
It is found that the peak current of UA on G/GCE is higher than that of CNTs/GCE, that is because the graphene which is two dimensionality structure have larger specific surface area and better electrical conductivity than that of CNTs which is one dimensionality structure, so catalytic action for uric acid oxidation is stronger on G/GCE.

Dynamic simulation of Petlyuk column for separation of ternary mixtures Lianying Wu1a, Ranran Zhao1b College of chemistry and chemical engineering, Ocean University of China. 266100, Qingdao，CHINA awulianying@ouc.edu.cn , bunionpayatm@163.com Key words: Dynamic simulating; Petlyuk column; control scheme; RGA Abstract: The Petlyuk distillation configuration has received considerable attention because of its efficiency to reduce the energy required for the separation of ternary mixtures.
A thermally coupled structure shows an interconnection between two columns with a liquid or vapor extraction from the first column and a recycle stream from the other column in the other phase; such interconnection can be implemented in place of a reboiler or a condenser of one of the columns.
Wolff and Skogestad[2] carried out a control analysis of the Petlyuk system and found the system to be controllable when a three-point control structure was implemented.
The control performance of several alternative structures to the Petlyuk column has been recently reported[6] and the results showed that the control behavior of the Petlyuk system is not necessarily improved by lowering the number of thermal couplings.
Conclusion The structure of the Petlyuk system offers some control challenges arising from the transfer of vapor streams back and forth between the columns.

Introduction As is well known, EPDM and its composites have been widely used in industry and household fields due to the excellent mechanical properties and the excellent chemistry stability.
In order to understanding thermal transport in EPDM and its composites, microscopic research on structure-property relationships is necessary.
Physical Model and Simulation Procedure Potential and Molecular Structure for EPDM.
The molecular structure of EPDM is built by Materials Studio® software [12].
Then after, an initial constant energy (NVE) simulation is performed to get the equilibrated structure in micro-canonical ensemble.

%Cr irons with stable ferritic matrix structures can provide superior heat resistance compared to the austenitic matrix 2.5-3.2wt.
The structure and chemical composition of the oxide layer were analyzed by X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS).
The XRD diffraction pattern of the iron exposed for 24 h (Fig. 3) indicated that V and Fe can accompany in the chromium-rich oxide structure so that the outer oxide layer comprises of chromia (Cr2O3) and (Cr,Fe,V)2O3.
The incorporation of vanadium in the chromium-rich oxide structure can be beneficial in retarding oxidation rate.

Measurement methods, such basic physical properties (water vacuum saturation and helium pycnometry), pore structure characterization (mercury porosimetry) and mechanical properties (compressive and bending strengths) and experimental results are described and discussed.
The pore structure characteristics were measured by mercury intrusion porosimetry.
Although the utilization of the building material is restricted for non-loading structures, its advantages (mainly thermal resistance) do its utilization suitable and appropriate.
However the pore structures of all studied composites were really different.
Basic physical properties and mainly the pore structure influenced all other properties.

In the perovskite structure, the Pb2+ vacancy concentration in grains can reduce the mechanical tension on the grain boundaries.
The phase structures of the samples were analyzed using X-ray diffractometry with a 2θ range from 100 to 900.
It was apparent that when the Pb content was higher than 0.96, the specimens exhibited a pure perovskite structure, while there were no detectable traces of the ZrO2 or other impurities observed.
The existence of ZrO2 changes the Zr/Ti ratio in the proverskite structure, and the main phase translates to tetragonal phase.
