摘要：
A resonance light scattering (RLS) method for the detection of fluoride ions in aqueous solution is reported in this paper. Uranyl-bis-salophen (UBS), a binuclear uranyl complex prepared by the reaction of uranyl with a ditopic tetradentate Schiff base ligand bis-salophen, was used for the experiment. It is found that after UBS self-assembled with pyrophosphate to form a uranyl coordination supramolecular polymer (SP), the system produced a strong RLS signal. When fluoride ions coexisted with UBS, the formation of SP was inhibited due to which the fluoride ions occupied the coordination sites in UBS. This resulted in RLS quenching. Based on these findings, we established a RLS method for the detection of fluoride ions in aqueous solution. Under optimal conditions, the linear range was found to be 0.005 to 1.5 nmol mL-1 with a detection limit of 0.0028 nmol mL-1. The method was applied to determine fluoride ions in environmental water samples with relative standard deviations of 1.3 to 3.1% and recoveries of 98.7-101.3%. © the Partner Organisations 2014.

摘要：
5-Propyl-4-amino-1,2,4-triazole Schiff base was characterized by FT-IR, <sup>1</sup>H NMR and X-ray single crystal diffraction techniques. The compound crystallizes in the triclinic space group p-1 with z = 2. The molecular geometry was optimized using density functional theory (DFT/B3LYP) and hartree fock (HF) methods with the 6-311G+(d,p) and 6-311G basis set in ground state. From the optimized geometry of the molecule, vibrational frequencies, HOMO-LUMO and natural bond orbital (NBO) were calculated with B3LYP/6-311G+(d,p) level. In addition, gauge independent atomic orbital (GIAO) <sup>1</sup>H NMR chemical shift values was calculated at B3LYP/6-311G+(d,p) and HF/6-311G+(d,p) level. ©2014 Elsevier B.V. All rights reserved.

摘要：
Two novel methods, first derivative spectrophotometric method ( <sup>1</sup>D) and first derivative ratio spectrophotometric method ( <sup>1</sup>DR), have been developed for the simultaneous trace determination of rhodamine B (RhB) and rhodamine 6G (Rh6G) in food samples after dispersive liquid-liquid microextraction (DLLME). The combination of derivative spectrophotometric techniques and DLLME procedure endows the presented methods with enhanced sensitivity and selectivity. Under optimum conditions, the linear calibration curves ranged from 5 to 450 ng mL<sup>-1</sup>, with the correlation coefficients (r) of 0.9997 for RhB and 0.9977 for Rh6G by <sup>1</sup>D method, and 0.9987 for RhB and 0.9958 for Rh6G by <sup>1</sup>DR method, respectively. The calculated limits of detection (LODs) based on the variability of the blank solutions (S/N = 3 criterion) for 11 measurements were in the range of 0.48-1.93 ng mL<sup>-1</sup>. The recoveries ranged from 88.1% to 111.6% (with RSD less than 4.4%) and 91.5-110.5% (with RSD less than 4.7%) for <sup>1</sup>D and <sup>1</sup>DR method, respectively. The influence of interfering substances such as foreign ions and food colorants which might be present in the food samples on the signals of RhB and Rh6G was examined. The developed methods have been successfully applied to the determination of RhB and Rh6G in black tea, red wine and chilli powder samples with the characteristics of simplicity, cost-effectiveness, environmental friendliness, and could be valuable for routine analysis. ©2014 Elsevier B.V.

摘要：
Protein nitration is an important post-translational modification regulating protein structure and function, especially for heme proteins. Myoglobin (Mb) is an ideal protein model for investigating the structure and function relationship of heme proteins. With limited structural information available for nitrated heme proteins from experiments, we herein performed a molecular dynamics study of human Mb with successive nitration of Tyr103, Tyr146, Trp7 and Trp14. We made a detailed comparison of protein motions, intramolecular contacts and internal cavities of nitrated Mbs with that of native Mb. It showed that although nitration of both Tyr103 and Tyr146 slightly alters the local conformation of heme active site, further nitration of both Trp7 and Trp14 shifts helix A apart from the rest of protein, which results in altered internal cavities and forms a water channel, representing an initial stage of Mb unfolding. The computational study provides an insight into the nitration of heme proteins at an atomic level, which is valuable for understanding the structure and function relationship of heme proteins in non-native states by nitration. © 2014 Elsevier Ltd.

摘要：
The novel quantum topological indices PY<inf>1,2</inf>were derived from molecular structure combined with the effect of atom space, the character of bonding atoms (such as equilibrium electro-negativity) and the branching effect between the atoms. The quantitative structure-property relationships (QSPRs) were proposed between PY<inf>1,2</inf>and the thermodynamic properties (<inf>f</inf>H<sup>θ</sup>, <inf>f</inf>G<sup>θ</sup>and Δ<inf>f</inf>G<inf>R</inf><sup>θ</sup>) of phenoxazine (Phx) and 135 kinds of polychlorinated phenoxazines (PCPXs), by Multiple linear regression (MLR) analysis method. The high-quality prediction models were evidenced by the correlation coefficient R, the standard error of estimate S, the Fisher statistic value and the cross-validated correlation coefficient RCV. With the new QSPR model, we are able to predict a wide range of thermodynamic properties of an extensive number of molecules. And the model is statistically significant and shows good stability for data variation as tested by the leave-one-out cross-validation (LOO-CV). ©2014 Published by Elsevier B.V.

摘要：
Electrochemical behaviors of U(VI) in 1-butyl-3-methylimidazolium chloride (C4MimCl) with various water contents investigated by chronopotentiometry and cyclic voltammetry. The electrochemical reduction of U(VI) was identified to follow two processes: a lower valence intermediate U(V) was initially formed at the potential of ca. -0.2 V(vs. Ag wire). Then, further deposition of UO2 was followed at around -0.8 V. Little amount of water (1–4 wt%) in C4MimCl, however, has an effect on the U(VI) reduction by changing the current density of the redox reaction and the diffusion coefficient of U(VI) in C4MimCl. The deposited product by potentiostatic electrolysis on the surface of stainless steel electrode was characterized by the scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and X-ray diffraction (XRD) methods. Although the electrodeposited black film was amorphous, the electrochemical reduced product of U(VI) can be still confirmed to be UO2 by XRD after the crystallization of the amorphous deposits at 1,073 K in nitrogen atmosphere. © 2014,Akadémiai Kiadó, Budapest, Hungary

摘要：
A novel core-shell magnetic nano-sorbent with surface molecularly-imprinted polymer coating was prepared via a sol-gel process. Methyltrimethoxysilane and 3-aminopropyltriethoxysilane were used as functional monomers, tetraethyl orthosilicate as cross-linker, and Al3+ as dopant to generate Lewis acid sites in the silica matrix for the metal coordinate interactions with the template dimetridazole (DMZ). The ratios of the monomers, the dopant, and the cross-linker, were optimised by a OA9 (34) orthogonal array design. The resultant sorbent was characterised by scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, powder X-ray diffraction, and magnetometry. The binding performances of the sorbent were evaluated by static, kinetic and selective adsorption experiments. The nano-sorbent was successfully applied to solid phase extraction followed by spectrophotometric determination of DMZ in real samples. Spiked recoveries ranged from 90.33% to 106.20% for egg, milk powder, and pig feed samples, with relative standard deviations of less than 4.54%. © 2014 Elsevier Ltd. All rights reserved.

摘要：
A novel and highly sensitive electrochemical DNAzymes biosensor was fabricated using Au nanoparticles (AuNPs) immobilized on the surface of Au electrode that had been previously modified with self-assembled monolayers of 1,6-hexanedithiol. Different modified electrodes were prepared and characterized by cyclic voltammetry and electrochemical impedance spectroscopy. The AuNPs were found to have a large surface area to anchor a large number of negatively charged phosphate backbones of DNAzymes, which further absorbed the electroactive indicator of hexaammineruthenium(III) ([Ru(NH 3 ) 6 ] 3+ ) to amplify the electrochemical signal. In the presence of target molecules, a large amount of DNA partly associated with [Ru(NH 3 ) 6 ] 3+ were removed from the electrode surface, leading to a significant decrease in peak current. Differential pulse voltammetry signals of [Ru(NH 3 ) 6 ] 3+ provided quantitative measures of the concentrations of uranyl ion (UO 2 2+ ), with linear calibration ranging from 13 pM to 0.15 nM and a detection limit of 5 pM. The presence of other metal ions did not affect the detection of UO 2 2+ , which indicated the high specificity of UO 2 2+ . Therefore, a new electrochemical DNAzymes sensor was designed with specific DNAzymes and AuNPs as immobilization platform and signal amplifier. © 2014 Akadémiai Kiadó, Budapest, Hungary.

以异佛尔酮二异氰酸酯（IPDI）、4,4_二环己基甲烷二异氰酸酯（HMDI）、聚醚二元醇（ PTMEG_2000）为单体,用N_甲基二乙醇胺作亲水扩链剂,制备阳离子型水性聚氨酯（ WPU）,并对其进行了红外光谱和粒径分析,主要探讨了影响阳离子水性聚氨酯固含量、断裂伸长率、吸水率的因素如混合二异氰酸酯摩尔比n （ IPDI/HMDI ）、预聚时二异氰酸酯与二元醇摩尔比n（二异氰酸酯/二元醇）、N_甲基二乙醇胺用量、三羟甲基丙烷用量和中和度.结果表明：当n（ IPDI/HMDI）在0.47：1与0.23：1之间时,所制得的阳离子型水性聚氨酯的固含量、断裂伸长率和吸水率均呈较稳定的状态；预聚阶段n（二异氰酸酯/二元醇）对WPU固含量影响不大,对断裂伸长率、吸水率影响明显；MDEA的用量对固含量、断裂伸长率和吸水率都有较深的影响；TMP的用量对WPU膜的固含量、吸水率及断裂伸长率影响一般；中和度对WPU固含量以及断裂伸长率的影响不大,但对吸水率影响较大.

摘要：
A novel functionalized material（SAM-Si-β-CD） was prepared with grafting β-cyclodextrin（β-CD） to silica gel（Si-β-CD） containing salicylamide（SAM）. characterized using XPS,SEM and FTIR techniques.Variables of batch experiments including pH, temperature, contact time, interfering ions were studied. Freundlich and Langmuir isotherm and the first order rate equation were suitable to describe the adsorption process. The results showed that the adsorption of uranium（VI） could achieve equilibrium within 60 minutes. The maximum adsorption capacity（6.45 mg/g） for UO2+ 2was obtained at corresponding experimental conditions. Additionally, the synthesized adsorbent effectively adsorbed UO2+2 in aqueous solution in the presence of interfering ions（Fe3+, Cu2+, Mg2+ and Na+）.

摘要：
用5-磺基水杨醛与邻苯二胺反应，合成了水溶性良好的四齿西佛碱配体磺基 Salophen。研究了磺基 Salo-phen 与铀酰离子发生配位反应生成配合物铀酰-磺基 Salophen 过程的荧光光谱。结果表明，磺基 Salophen 与铀酰配位后体系的荧光显著增强，最大发射波长位于428 nm。应用该反应建立了荧光分析法测定水溶液中铀酰离子的新方法。在优化条件下测定铀酰的线性范围为0.03~4.0 nmol/ mL，检出限为0.015 nmol/ mL。应用建立的荧光法测定了实际水样中的铀酰，回收率为97.0％~104.0％。

摘要：
血红素蛋白在生物体系中执行多种重要的生物功能,如氧贮存和运输、电子传递、生物催化和生物传感等.尽管大多数血红素蛋白是以单体形式存在,一些血红素蛋白在体外和/或体内,还会形成同源聚合物.本文综述了血红素蛋白的二聚、寡聚与多聚研究进展,包括肌红蛋白、细胞色素c、胞红蛋白,细胞色素b5、细胞色素b562、亚硝酸盐还原酶、血红素传感蛋白和血红素转运蛋白等,着重介绍其结构与功能以及多聚体分子设计的方法与应用.这些研究进展,一方面增强了我们对生物体系中血红素蛋白结构与功能关系的认识,另一方面也赋予了我们通过多聚方法设计功能蛋白来调控和利用血红素蛋白的能力.
