	1	Sensitive Voltammetric Determination of Captopril Using a Carbon Paste Electrode Modified with Nano-TiO_2/Ferrocene Carboxylic Acid显示文摘A carbon paste electrode (CPE) modified with ferrocene carboxylic acid (FcCA) and TiO2 nanoparticles was constructed by incorporating TiO2 nanoparticles and ferrocene carboxylic acid into the carbon paste matrix. The electrochemical behavior of captopril (CAP) at the surface of the modified electrode was investigated using electroanalytical methods. The modified electrode showed excellent electrocatalytic activity for the oxidation of CAP in aqueous solutions at physiological pH values. Cyclic voltammetric curves showed that the oxidation of CAP at the surface of the modified electrode reduced its overpotential by more than 290 mV. The modified electrode was used for detecting captopril using cyclic voltammetry and square wave voltammetry techniques. A calibration curve in the range of 0.03 to 2400 μmol/L was obtained that had a detection limit of 0.0096 μmol/L (3?) under the optimized conditions. The modified electrode was successfully used for the determination of captopril in pharmaceutical and biological samples.	Jahan Bakhsh RAOOF Reza OJANI Mehdi BAGHAYERI	2011	催化学报2011，32，11：	6
	2	三轴椭球模型下的SZ效应星系团计数显示文摘在不久的将来,若干基于SZ效应的巡天计划即将观测到大量的星系团.分别采用星系团暗物质的球模型和椭球模型,给出了可观测SZ星系团数目的理论预测,并讨论了形状对星系团数目不确定性的影响.在计算中,利用星系团维里平衡的条件,通过巡天观测的流量下限来确定可观测星系团质量下限,进一步由质量函数给出星系团数目预测. 计算结果表明:若通过SZ巡天观测来限定宇宙学参数,形状引起的系统不确定性要予以考虑.	沈国鹏虞骏	2005	天文学报2005，46，4：	0
