New Horizons in Pulse Voltammetry

这个项目是在分析和表面化学的一般领域和在电分析化学的子领域。这项活动的主要推力是发展应用于微和超微电极的正反脉冲方波伏安技术。这些电极的直径小于25微米，由铂、碳、钨和镀汞的铱制成。使用它们作为伏安传感器减轻了许多电阻限制，遇到了更大的电极。奥斯特杨博士开发了描述这些电极上预期的脉冲伏安反应的理论，用于分析和动力学应用。脉冲伏安技术在微、超微电极上的应用提供了新的、灵敏的电化学测量技术，在痕量分析、材料表征和生物系统的体内研究中具有广泛的应用前景。

This project is in the general area of analytical and surface chemistry and in the subfield of electroanalytical chemistry. The primary thrust of this activity is develop normal and reverse pulse squarewave voltammetric techniques for application to micro- and ultramicroelectrodes. These electrodes, which have diameters less than 25 micrometers, are fabricated from platinum, carbon, tungsten, and mercury-coated iridium. Use of them as voltammetric sensors alleviates many of the electrical resistance restrictions that are encountered with larger electrodes. The theory which describes the pulse voltammetric responses expected at these electrodes is being developed by Dr. Osteryoung for analytical and kinetic use. The application of pulse voltammetric techniques to micro- and ultramicroelectrodes provides new, sensitive electrochemical measurement technologies that should have broad application in trace analysis, materials characterization, and in vivo studies of biosystems.
