摘要：
Permethrin is popularly used in a variety of therapeutic areas. However, the poor water solubility of permethrin seriously limits its wider clinical applications. The present study demonstrates that solubility of permethrin in aqueous solution can considerably increase in the presence of β-cyclodextrin (β-CD). Extensive experimental data along with computational modeling reveal the formation of stable permethrin/β-CD inclusion complexes, including permethrin(β-CD) and permethrin(β-CD) <inf>2</inf>, through hydrophobic binding. Both permethrin(β-CD) and permethrin(β-CD)<inf>2</inf> complexes coexisted in aqueous solution, and the ratio of the concentration of permethrin(β-CD) complex to that of permethrin(β-CD)<inf>2</inf> complex was dependent on the concentration of β-CD. The complexation of permethrin with β-CD significantly improved the bioavailability of permethrin and, therefore, increased the bioactivity. The significant increase of the bioactivity of permethrin in the presence of β-CD provides an effective approach to improve the practical use of permethrin in public health and agriculture. ©2006 American Chemical Society.

摘要：
The title complex, [CaZn(C<inf>3</inf>H<inf>2</inf>O<inf>4</inf>) <inf>2</inf>(H<inf>2</inf>O)<inf>4</inf>]<inf>n</inf>, is a two-dimensional polymer and consists of CaO<inf>8</inf> and ZnO<inf>6</inf> polyhedra linked together by malonate ligands. The Ca<sup>II</sup> cation, lying on a twofold axis, is coordinated by two water molecules and six malonate O atoms. The Zn<sup>II</sup> cation, which lies on an inversion center in an octahedral environment, is coordinated by four malonate O atoms in an equatorial arrangement and two water molecules in axial positions. The Zn - O and Ca - O bond lengths are in the ranges 2.0445(12)-2.1346(16) and 2.3831(13)-2.6630(13), respectively. The structure comprises alternating layers along the [101] plane, the shortest Zn&mellip;Zn distance being 6.8172(8). The whole three-dimensional structure is maintained and stabilized by the presence of hydrogen bonds. ©2006 International Union of Crystallography.

摘要：
A series of nickel complexes with β-ketoamine ligands based on pyrazolone derivatives were synthesized by condensing pyrazolone with aniline, 2-chloroaniline or naphthylamine and then reacting the produced β-ketoamine with nickel halide. The solid-state structures of these three complexes were determined by single-crystal X-ray diffraction. The bis(β-ketoamine)nickel complexes are all air-stable and can act as highly active catalyst precursors for styrene polymerization with activation of methylaluminoxane under mild reaction conditions. The activity of the catalyst for styrene polymerization is as high as 2.10 × 105 g polymer/mol Ni h. Both steric and electronic effects were found to be important and influential for catalytic activity. Copyright © 2005 John Wiley & Sons, Ltd.

摘要：
A method for determination of L-dopa by the adsorption stripping voltammetry (ASV) using a multiwalled carbon nanotubes (MWNTs)-Nafion modified glassy carbon electrode (GMGCE) was proposed. This chemically modified electrode (CME) shows a better stability. A sensitive oxidation peak was observed and the anodic peak potential is ca. 0.374V (vs. SCE). The influences of various experimental parameters on the current peak were completely studied. Under the optimized condition, the method has been applied to the determination of L-dopa in samples. There is a good linear relationship between the peak current (i p) and L-dopa concentration in the range of 3.5 × 10 -7 ∼ 1.5 × 10-5 mol/L, with the limit of detection 5.0 × 10-8 mol/L.

摘要：
A new method, which involves dynamic liquid-phase microextraction followed by HPLC with variable wavelength detection, was developed to determine phoxim in water samples. Experimental parameters affecting the extraction efficiency, such as extraction solvent, solvent volume, sampling volume, dwell time, number of samplings, and salt concentration were investigated. Under the optimal extraction conditions, phoxim was found to yield a good linear calibration curve in the concentration range from 0.01 to 10 μg/mL. The LOD is 2 ng/mL, and RSD at the 100 ng/ mL levels is 8.9%. Lake water and tap water samples were successfully analyzed using the proposed method. ©2006 Wiley-VCH Verlag GmbH &Co. KGaA, Weinheim.

Adsorption;Biomacromolecule;Interaction;Ion-exchange;Theory
摘要：
In this article, a series of mathematical and physical models for the adsorption of biomacromolecules are established. As shown, the adsorption of biomacromolecules is actually considerably complicated and often involves various interactions, such as electrostatic, hydrophobic, and hydrogen-bonding, etc. Considering this, these models show that if these interactions are heavily involved in the process, the plot of ln Q (or Q) vs ln C* is normally expected to be a straight-line. Otherwise, if the linearity exists between C*/Q vs C*, the adsorption would be an ideal process without the intervention of them. Meanwhile, this article also presents corresponding relationships for the adsorption in multisited binding and multilayer forms. Other aspects including ion-exchange systems are also discussed (C*, the equilibrium concentration of biomacromolecules; Q, the adsorbance). Copyright © 2006 by Humana Press Inc.

摘要：
To investigate the influence of a fluorine moiety on the biological activity of phenoxyacetoxyalkylphosphonates, a series of fluorine-containing phenoxyacetoxyalkylphosphonates were synthesized and screened for herbicidal activity in a greenhouse. The majority of the title compounds showed better preemergence activity than postemergence activity against the test plants, especially on monocotyledon. Compound 5l exhibited notable activity. Results showed that by introducing a fluorine moiety to the parent structure of phenoxyacetoxyalkylphosphonates, a series of new compounds with satisfactory herbicidal activity could be synthesized. A reasonable combination of a fluorine moiety and other substituents on the benzene ring had a great influence on the herbicidal activity.

摘要：
The degradation of imazapyr in four soils was investigated under laboratory aerobic and anaerobic conditions. Under aerobic conditions, imazapyr degraded faster in yellow-red soil than in other soils, and its persistence decreased depending on soil pH in the order coastal soil (pH 8.8) >silt-loamy paddy soil (pH 7.9) >fluvio-marine yellow loamy soil (pH 7.1) >Yellow-red soil (pH 5.3). However, soil pH did not affect imazapyr degradation under anaerobic conditions. The half-lives of imazapyr in soils under aerobic conditions were in the range of 26-44 days estimated by the first-order kinetics model, while 3-10 days calculated by two-stage model under anaerobic conditions. The preceding results demonstrated that anaerobic conditions contributed to imazapyr disappearance in soils. Based on the spectral data of APCI-MS, <sup>1</sup>H NMR and IR, structures of the following metabolites: 2,3-pyridinedicarboxamide, 2,3-pyridinedicarboxylic anhydride and 2,3-pyridinedicarboximide for aerobic treatments;2,3-pyridinedicarboxylic anhydride and 2-(4-hydroxy-5-oxo-2- imdazolin-2-yl) nicotinic acid for anaerobic treatments, were identified. Degradation mechanism under the different conditions was also discussed. ©2006 Taylor &Francis.
