Box 211, Amsterdam, 1000 AE, Netherlands Abstract:The adsorbents of starch grafted p-tert-butyl-calix[4,6,8]arene-SGCn (SGC4, SGC6, SGC8) are prepared. The products are characterized by FTIR, elemental analysis, thermal gravimetric analysis and scanning electron microscope. Static adsorption behavior is studied by using SGC8 as adsorbent, butyl Rhodamine B (BRB) solution as simulation dye wastewater. The adsorption of BRB onto SGC8 fits the second order kinetic model and the apparent adsorption rate constant is 0.002gmg-1min-1 at 25°C. The equilibrium adsorption data are interpreted using Langmuir and Freundlich models. The adsorption of BRB onto SGC8 is better represented by the Langmuir equation. The thermodynamic parameters for the adsorption reaction are calculated through van't Hoff analysis. The adsorbent may be easily regenerated by using ethanol solution as desorption agent to extract dye from SGC8. The rate of desorption of BRB is dependent on the concentration of ethanol and the temperature. SGC8 exhibits excellent adsorption and desorption properties toward dye molecule. The new-style adsorbent of SGC8 is regarded as a potential adsorbent to deal with dye or organic wastewater. © 2010 Elsevier B.V.

Box 211, Amsterdam, 1000 AE, Netherlands Abstract:Na-doped ZnO nanowires with an average diameter of ~. 40. nm have been fabricated by a thermal decomposition route at temperatures around 400°C. Their properties have been investigated using X-ray diffraction, field emission scanning electron microscope, Raman spectra, photoluminescence spectra and X-ray photoelectron spectra. Photoluminescence spectra showed that the as-synthesized ZnO samples exhibited strong visible emission with a major peak at 420. nm. Furthermore, intensity of the visible emission at 420. nm enhanced as the increase of Na concentration. The improvement of visible emission in the Na-doped ZnO samples should be a result of the surface defects increased by doping of Na in ZnO. Their antibacterial activities were also evaluated by determination of minimum inhibitory concentration (MIC) against Escherichia coli 25922 in vitro. Antibacterial tests indicated these nanomaterials showed good antibacterial properties after UV illumination for a short time. © 2010 Elsevier B.V.

The effects of different kinds of surfactants on the electrochemical response to topotecan hydrochloride were examined. The results indicate the electrochemical signal was apparently improved by SDS. At optimal conditions, the oxidative peak current increased linearly with the logarithm of concentrations for topotecan hydrochloride in the ranges of 2.0 × 10-12 to 1.0 × 10-11 mol/L and 8.0 × 10-11 to 8.0 × 10 -10 mol/L with a detection limit of 6.4 × 10-13 mol/L. The proposed method could be applied in determining topotecan hydrochloride in urine. © 2010 Science China Press and Springer-Verlag Berlin Heidelberg.

Issue date:2011 Publication year:2011 Pages:63-76 Language:English ISSN:00405752 CODEN:THAGA6 Document type:Journal article (JA) Publisher:Springer Verlag, Tiergartenstrasse 17, Heidelberg, D-69121, Germany Abstract:Starch paste viscosity plays an important role in estimating the cooking, eating, and processing quality of rice. The inheritance of starch paste viscosity in glutinous rice remains undefined. In the present study, 118 glutinous rice accessions were collected, and the genotypes of 17 starch synthesis-related genes (SSRG) were analyzed by using 43 gene-specific molecular markers. Association analysis indicated that 10 of 17 SSRGs were involved in controlling the rapid visco analyzer (RVA) profile parameters. Among these, the PUL gene was identified to play an important role in control of peak viscosity (PKV), hot paste viscosity (HPV), cool paste viscosity (CPV), breakdown viscosity (BDV), peak time (PeT), and paste temperature (PaT) in glutinous rice. Other SSRGs involved only a few RVA profile parameters. Furthermore, interactions between SSRGs were found being responsible for PeT, PaT, and BDV. Some of the RVA parameters, including PKV, HPV, CPV, CSV, and PaT, were mainly governed by single SSRG, whereas other parameters, such as BDV, SBV, and PeT, were controlled by a few SSRGs, functioning cooperatively. Further, three near-isogenic lines (NIL) of a japonica glutinous cv. Suyunuo as genetic background, with PUL, SSIII-1, and SSIII-2 alleles replaced with those of indica cv. Guichao 2, were employed to verify the genetic effects of the various genes, and the results were consistent with those obtained from the association analysis. These findings indicated that starch paste viscosity in glutinous rice had a complex genetic system, and the PUL gene played an important role in determining the RVA profile parameters in glutinous rice. These results provide important information for potentially improving the quality of glutinous rice. © 2010 Springer-Verlag.
