| 9 | Scanning electrochemical microscopy-development of instrumentation utilizing piezo-bimorph X-Y scanners显示文摘The development of the instrumentation of a scanning electrochemical microscopy (SECM) is presented. The core of the SECM sensing system is constructed based on piezobimorph scanners, a mechanical micropositioner of multi-dimensional adjustment and ultramicroelectrodes. The control of the electrochemical cell and the SECM system is realized by a battery powered bipoteniostat and analog control circuits respectively with the control of a microcomputer work station. The demonstrations of SECM experiments are given on both a standard IDA sample and a silver electrode. Discussions on the resolution and quality of SECM image are made. | MAO, BW MU, JQ ZHUO, XD FENG, ZD YAN, ER PAN, GB XIE, ZX REN, B | 1995 | Chinese Journal of Chemistry1995，13，2： | 0 |
