Issue date:February 2011 Publication year:2011 Pages:143-149 Language:English ISSN:0021891X CODEN:JAELBJ Document type:Journal article (JA) Publisher:Springer Netherlands, Van Godewijckstraat 30, Dordrecht, 3311 GZ, Netherlands Abstract:The poly(bromothymol blue) film was prepared using a simple cyclic voltammetry method. Field emission scanning electron microscopy and electrochemical methods were employed to characterize this film. When the film was electropolymerized on an electrode, it showed excellent catalytic activity toward the oxidation of dopamine (DA) in pH 4.0 phosphate buffer solution. In addition, the overlapped voltammetric responses of dopamine and ascorbic acid were resolved into two well-defined peaks by the film-modified electrode with a large peak separation of 0.17 V. A calibration curve for DA was obtained by the amperometric method in the range of 3.0-195.0 μM with a correlation coefficient of 0.9997. The film-modified electrode has been successfully used to measure the concentration of DA in injections and human serum samples. © 2010 Springer Science+Business Media B.V.

Box 211, Amsterdam, 1000 AE, Netherlands Abstract:Monodispersed hybrid silica spheres with particles sizes up to 4 μm were obtained by controlling the number of nuclei generated in the initiation phase of particle formation using a two-step sol-gel method. This method has two advantages: (i) the particle size can be tuned easily just by variation of the amount ammonia added in the step of precursor hydrolysis, and (ii) the amount of precursor used to prepare particles with the same diameter is at least ten times lower than with traditional methods. The effects of stirring speed and stirring time on the resulting particle size were also studied. © 2010 Elsevier B.V. All rights reserved.

Interface interactions between the micro-porous thin film and a cationic surfactant, cetyltrimethylammonium bromide (CTAB), are investigated by in-situ AFM in aqueous solutions. An interesting phenomenon was observed in water and CTAB solution, which the dimensions of the micropores are remarkably larger than the dimensions of those in air. The solid thin films exhibit different surface morphologies in response to stimulus by different concentrations of CTAB. These observations were explained by positing that the PAA chains in the micropores stretch and contract with interface interactions between PAA and CTAB. A promising electrochemical application of this film is suggested. This study is aimed at strategies for the functionalization of stimulus-responsive micro-porous solid thin films with tunable surface morphologies, and exploring new smart materials. © 2010 Elsevier Inc.

Data from total of 3080 subjects in two pesticide factories were used. This was a population-based case-controlled study in China. In total, 18.3% of subjects with impaired glucose regulation (IGR) and 6.5% of subjects with diabetes, and the prevalence of abnormal glucose regulation was 24.8%, 86 subjects had known type 2 diabetes and 114 had newly diagnosed diabetes. The prevalence of subjects with abnormal glucose regulation increased from 21.3% in the controls to 29.3% in the exposures (χ2=33.182, P<0.001). Multivariate logistic regression was used to control potential confounders and calculate odd ratios as the estimate of effect. An indication of increased risk for abnormal glucose regulation was noted for exposure to pyrethroids (OR=1.482, 95%CI=1.238-1.774). Abnormal glucose regulation is common in subjects exposed to pyrethroids. The present investigation indicates the adverse health effects of pyrethroids are underestimated. © 2010 Elsevier Ltd.

The blowup properties of solutions for the same system are then given. It is shown that periodic solutions exist if the intra-specific competitions are strong whereas blowup solutions exist under certain conditions if the intra-specific competitions are weak. Numerical simulations and a brief discussion are also presented in the last section. © 2010 Published by Elsevier Ltd. All rights reserved.

Box 211, Amsterdam, 1000 AE, Netherlands Abstract:Monodisperse samarium-doped ceria nanocrystals have been rapidly synthesized by a microemulsionmediated hydrothermal method with secondary light irradiation treatment. The microemulsion system consists of cetyltrimethyl ammonium bromide and n-butanol and n-octane, acting as the surfactant, cosurfactant and oil phase, respectively. The as-synthesized nano powder is characterized by well-dispersed rhombohedral particles with their size in the range of 75 to 85 nm. The results demonstrate that it could effectively inhibit coarsening and agglomeration of the product nanocrystals during the phase formation process by using the light irradiation treatment instead of conventional heat treatment. © 2010 Elsevier B.V.
