Prediction of Swelling Behavior of AT-Isopropylacrylamide Hydrogels in Aqueous Solution of Sodium Chloride

In this paper, a model is presented to correlate and predict the swelling behavior of hydrogels in aqueous solutions of electrolytes. The model is a combination of VERS-model, "phantom network" theory and "free-volume" contribution. The VERS-model is used to calculate Gibbs excess energy; "phantom network" theory to describe the elastic properties of polymer network, and "free-volume" contribution to account for additional difference in the size of the species. To test the model, a series of N-isopropylacrylamide based hydrogels are synthesized by free radical polymerization in oxygen-free, deionized water at 25℃ under nitrogen atmosphere. Then, the degree of swelling of all investigated gels as well as the partition of the solute between the gel phase and the surrounding coexisting liquid phase are measured in aqueous solution of sodium chloride. The model test demonstrates that the swelling behavior correlated and predicted by the model agrees with the experimental data within the experimental uncert

10 Hot Topics on Chinese Plastics Industry in 2006

In 2006, the first year of the 11th Five-Year Plan, Chinese plastics industry made great achievements, such as the breakthrough on raw materials manufacturing and more plastics brands awarded Chinese Brands etc. In 2006, "safety" is the most frequently referred word."Personal safety","food safety"and "environmental safety" all have close relationship with plastics. The promulgation of regulations and the revision of standards surely would boost the awareness of quality and innovation. We need not only products, but also safety, energy-saving and environmental friendly green consumption. Thus, the recycling of plastics also became a hot topic. Hereby, World Plastics magazine and the China Plastics Processing Industrial Association compiled 10 hot topics of the plastics industry jointly as a generalization of 2006.

THE EFFECT OF LIQUID PHYSICAL PROPERTIES ON DRIFT VELOCITY

Drift velocity is a very important paramcter for predictirg the pool volumetric void fraction. Two-phase system of gas and high viscous liquids pool is encountered in various engineering applications. A review of the literature shows no data for explaining the effect of highly viscous liquids on the drift velocity. This paper's analysis shows that there is a considerable influence. It is shown that the foaming behaviour of liquids is dependent on the surface properties. For some highly viscous liquids at a given superficial gas velocity, the viscosity changes with time. The effect of "foam" and "time" on drift velocity is clearly elucidated.

Post-illumination activity of Bi2WO6 in the dark from the photocatalytic“memory”effect

Photocatalysts with the photocatalytic"memory"effect could resolve the intrinsic activity loss of traditional photocatalysts when the light illumination is turned off.Due to the dual requirements of light absorption and energy storage/release functions,most previously reported photocatalysts with the photocatalytic"memory"effect were composite photocatalysts of two phase components,which may lose their performance due to gradually deteriorated interface conditions during their applications.In this work,a simple solvothermal process was developed to synthesize Bi2WO6 microspheres constructed by aggregated nanoflakes.The pure phase Bi₂WO₆ was found to possess the photocatalytic"memory"effect through the trapping and release of photogenerated electrons by the reversible chemical state change of W component in the(WO₄)^2–layers.When the illumination was switched off,Bi₂WO₆ microspheres continuously produced H₂O₂ in the dark as those trapped photogenerated electrons were gradually released to react with O₂ through the two-electron O₂ reduction process,resulting in the continuous disinfection of Escherichia coli bacteria in the dark through the photocatalytic"memory"effect.No deterioration of their cycling H2O2 production performance in the dark was observed,which verified their stable photocatalytic"memory"effect.
