| 1 | Electrochemical synthesis of silver nanoparticles-coated gold nanoporous film electrode and its application to amperometric detection for trace Cr(VI)显示文摘A simple and rapid approach for the electrochemical synthesis of Ag nanoparticles-coated gold nanoporous film (AgGNF) on a gold substrate was reported. The solid gold electrode (SGE) was directly anodized under a high potential of 5 V, and then reduced to obtain gold nanoporous film (AuNF) by freshly prepared ascorbic acid. The Ag nanoparticles (AgNPs) were grown on the AuNF electrode by potential-step electrodeposition. The resulting AgGNF composites electrodes were characterized by scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectroscopy and cyclic voltammetry (CV). As-prepared AgGNF electrode was used as a kind of superior sensor for Cr(VI) detection, which exhibited better electrocatalytic behavior than those of AuNF and SGE under identical conditions. Such a designed AgGNF nanocomposites electrode showed outstanding sensitivity (about 0.15 nA/ppb) and favorable reproducibility for Cr(VI) detection. The dependence of reduction current on Cr(VI) concentration is linear from 2 to 370 ppb with a low detection limit of 0.65 ppb. Interferences from other heavy metals ions (Cr3+, Cu2+, Pb2+, As3+ and Hg2+) associated with Cr(VI) analysis could be effectively diminished. The present method proves to be rapid, reliable, sensitive and low-cost. | XU He ZHENG QiaoLi YANG Ping LIU JianShe XING SuJie JIN LiTong | 2011 | Science China Chemistry2011，54，6： | 9 |
| 2 | An investigation on a novel PDLC film's fabrication and its electro-optical properties显示文摘A polymer dispersed liquid crystal (PDLC) film that has good electro-optical properties is produced by the method of polymerized-induced phase separation. Based on the application foreground, its capability parameters, such as contrast ratio, work voltage, and visual angle, are characterized for the first time by a white light but not a fixed wavelength light. The results show the PDLC film has a low work-voltage of 20 V, more than 150° visual angle, high stability, and long lifetime. The differences between plastic and glass ITO-coated substrates of PDLC films are also studied in this paper. The plastic substrate has better property and will have a wider perspective especially in the portable, tender and folded display devices. Due to adjustable properties of film by electric field, PDLC has the potential application for display device, sensor, switch, grating, and new generation analytical apparatus. | DING HongLiu, ZHAO Ting, CHENG YuXiao, PANG YueHong, XU He, SHI GuoYue & JIN LiTong Chemistry Department of East China Normal University, Shanghai 200062, China | 2007 | Science China Chemistry2007，50，3： | 2 |

| 4 | A simple and sensitive method for the determination of 4-n-octylphenol based on multi-walled carbon nanotubes modified glassy carbon electrode显示文摘A simple and sensitive electroanalytical method was presented for the determination of 4-n-octylphenol(OP) based on multi-walled carbon nanotubes(MWCNTs) modified glassy carbon electrode(GCE).OP was directly oxidized on the MWCNTs/GCE,and the electrochemical oxidation mechanism was demonstrated by a one-electron and one-proton process in the reaction.The oxidation peak current of OP was significantly enhanced by the use of MWCNTs/GCE compared with those of bare glassy carbon electrode,suggesting that the modified electrode can remarkably improve the performance for OP determination.Factors influencing the detection processes were optimized.Under these optimal conditions,a linear relationship between concentration of OP and current response was obtained in the range of 5 × 10-8 to 1 × 10-5 mol/L with a detection limit of 1.5 × 10-8 mol/L and correlation coefficient 0.9986.The modified electrode showed good selectivity,sensitivity,reproducibility and high stability. | Qiaoli Zheng Ping Yang He Xu Jianshe Liu Litong Jin | 2012 | Journal of Environmental Sciences2012，24，9： | 2 |
