Study on Photocatalytic Degradation of X-3B by TiO2 Nanotube Arrays Fei Rong1, 3 Jia Liu1,2,3 Zhijuan Zhang1,2 Degang Fu1,2,3 1State Key Laboratory of Bioelectronics, Southeast University, Nanjing 210096 2School of Chemistry and Chemical Engineering, Southeast University, Nanjing 211189 3Suzhou Key Laboratory of Environment and Biosafety, Suzhou, 215123 rong@seu.edu.cn Keywords: photocatalytic titanium dioxide nanotube array, anodization X-3B Abstract.
Morphologies and structures were examined by field-emission scanning electron microscopy (FESEM) and energy dispersive X-ray spectroscopy (EDX, LEO 1530-VP, Germany).

Meanwhile, volatile de-volatilization changes the phase structure of coke, makes the rest coke porous, so the more the volatile matter is, the larger the specific surface area of the rest coke is, as a result, the larger the area exposed to the air, the more easily the coke can be ignited, so that the minimum energy which the coal combustion needs (the activation energy E) is less.

The advantages of SHS technique include [8, 9]: (1) higher purity of the products and low cost; (2) low energy requirement, relative simplicity of the process and equipment, the heat released during exothermic reactions obtains a self-sustained system when raw materials are ignited without additional energy; (3) high efficiency, SHS is based on the use of chemistry reaction synthesis and sintering materials, saving sintering time at high temperature.
Fig. 2 (a) and (b) clearly show a homogenous structure and the visible porous.

This chemistry is also applied to couple with nanotubes with metal ionics in aqueous phase, thus forming a self-assembly interaction.
After filtering, the treated samples were thermal treated at 450°C under an argon atmosphere for 1hr to reinforce the whole structure and get rid of impurities from the CNTs.

Nonlinear Analysis of Water Resources Awareness of Different occupations in Heihe River Basin China LI Jian-lin1 and WANG Yan2 1Instituite of Resources & Environment, Henan Polytechnic University, Jiaozuo Henan , China 2Instituite of Physics & Chemistry, Henan Polytechnic University, Jiaozuo Henan , China a.e-mail: jian.lin.li@hotmail.com , b.e-mail: wangxiaoyan@hpu.edu.cn Keywords: Heihe River Basin; degree of water resources shortage (WRS); sociological survey; fractal dimension (D) Abstract: Based on sociological survey on the situation of water resources in Heihe River Basin China, using fractal theory, a nonlinear analysis of survey data was conducted according to different areas and different employments.
Therefore, the survey research from a sociological point of view of Heihe River Basin , which includes economic structure, social change, culture and water resources in awareness of tension , and so on, can make up for shortage of study on natural science, to promote the implementation of science policy.

Poly(acrylonitrile-methyl methacrylate) Based Microporous Gel Electrolyte for Li-ion Battery Weihua Pu1, Xiangming He1, Li Wang 1, Changyin Jiang1, Chunrong Wan1 and Shichao Zhang2 1 Materials Chemistry Lab, Institute of Nuclear & New Energy Technology, Tsinghua University, Beijing 100084, China 2 School of Material Science and Engineering, Beihang University, Beijing 100083, China Keywords: Poly(acrylonitrile-methyl methacrylate), microporous membrane, gel polymer electrolyte Abstract.
The dried membrane, typically having a thickness of 0.1 ± 0.05 mm and a white color due to its porous structure, was cut into small discs of Ф22mm or Ф16mm for further processing.

There are a large number of applications in solid state physics, materials science, chemistry and otherwise, where the positron is clearly the particle of choice over the electron.
Variation in the structure of the foil or adsorbed material at the front side of the foil will effect the image on the microchannel plate.

At the meeting, Anthony Turkevich (who was in fact my first year chemistry teacher in 1958 at Princeton University) suggested that NO would be a better quenching gas if spin exchange was the mechanism for the positronium quenching.
