By combined process of hot dip aluminum and micro–arc oxidation, a multilayer composite coating was obtained on the surface of 20 steel plates. The micro-hardness, morphology, residual stress and thermal-shocking performance of the coating were investigated by HVS-1000 micro-hardness instrument, SEM, X-350 stress instrument and etc. The results showed that the micro-hardness of the coating appeared hard-soft-hard from surface to inner, the effective thermal-shock times of the coating was 130, its residual stress of the coating was 181.7 MPa after hot shock 80 times.

Induces the operating principle of the induced radiation unit and studies the uniformity of indoor temperature distribution in the space and time, comfort and dewing condensation based on the PMV-PPD thermal comfort evaluation system. Through data collation and results analysis, obtains thermal comfort superiority and energy-saving potential of the reduced radiation air conditioning. The results show that the temperature distribution in the room stalled by the reduced radiation units is uniform, without sense of temperature difference and ventilation, providing an ultra-comfortable environment and that the indoor setting temperature can be up to 27°C on the premise of meeting comfort requirement. At the same time, air supply of low temperature can be achieved without condensation, reflecting the energy-saving potential of the system. These provide a reference for design of the induced radiation air conditioning system and further study.

With the industrial development, the problems of oil & gas resource consumption, environmental pollution and demand increase have become rising. Environmental pollution which leads to global warming and climate change comes from the contamination of water, air and soil from man-made waste. The advancement in science and technology for environmental protection will play a key role to ensure the improvement of environmental quality, and will contribute to the development of a healthy society. The programs of environmental research have been implemented, including promoting cleaner production of oil & gas resources, accelerating the process of oil & gas recovery, establishing the guarantee mechanism of the oil & gas field environment recovery, developing clean energy vehicles, improving the production quality and discharge standard of motor gasoline and vigorously developing clean energy. In addition, producing approaches and mechanism of the pollution are presented in the paper.

The epoxy resins were toughened with reactive core-shell nanoparticles(CSNPs) with butyl acrylate (BA) as the core and methyl methacrylate (MMA) copolymerizing with glycidyl methacrylate (GMA) as the shell. The chemical structure of the CSNPs was characterized by FT-IR. The morphology of toughened epoxy networks were analyzed by SEM and TEM, and their adhesion properties were also detected. The results show that mixing methods and CSNP concentration have great influence on the morphology and adhesion properties of the toughened epoxy networks. CSNPs are uniformly dispersed in the epoxy resins by the grinding method. The modified epoxy networks obtained from the modified epoxy networks prepared by the grinding method(MEPN2) with 10 wt% CSNPs show the best adhesion properties, and the increase in maximum peel strength, 25°C sheer strength and 150°C sheer strength of the modified epoxy networks is 401.3% , 46.9% and 27.6% respectively over the unmodified epoxy networks due to the small-scale coagulations of CSNPs.

Different Zinc tungstate (ZnWO4) nanostructures were controllably synthesized via facile hydrothermal method in the presence of surfactant polyethylene glycol 20000 (PEG-20000). During the synthesis, cheap and simple inorganic salts were used as precursors. The shape and size of ZnWO4nano/microstructures can be well controlled by the dosage of surfactant, the pH value of reaction system and other hydrothermal parameters. Apart from structural and morphological characterizations of the ZnWO4nano/microstructures, the composition and the photoluminescent (PL) properties of typical samples have also been investigated by powder X-ray diffraction pattern and fluorescence spectrophotometer, respectively. The results indicated that all the products of ZnWO4with different morphologies exhibited the only blue peak at 506 nm with an excitation wavelength at 253 nm.
