Scanning electrochemical microscope (SECM) for studying interfacial electrochemical phenomena, activities and interactions

扫描电化学显微镜（SECM）是一种在微观、纳米和分子尺度上对界面物理化学过程进行原位定量研究的研究技术。本提案中要求的CHI920C SECM是SECM家族中非常稳定和通用的设备。对基础和应用研究都有用，CHI920C SECM是一种非常敏感的仪器，它可以用作研究各种材料（金属，绝缘体和半导体）的局部性质和反应性的电化学工具。SECM具有广泛的应用，包括腐蚀研究，生物系统（例如，细胞和酶活性，单细胞通道中的离子传输），跨液/液界面的电荷传输，单分子，薄膜和膜的电化学检测。它也是评价不同材料在氧还原和氢氧化等有用反应中的电催化活性的有力工具。

Scanning electrochemical microscope (SECM) is a research technique for quantitative investigations of interfacial physicochemical processes in situ at the microscopic, nanoscopic and molecular scales in a wide variety of areas. The CHI920C SECM requested in this proposal is the extremely stable and versatile apparatus among the SECM family. Useful for both basic and applied studies, the CHI920C SECM is an extremely sensitive instrument, and it can be used as an electrochemical tool for studies of the local properties and reactivity of a wide variety of materials (metals, insulators, and semiconductors). SECM has a wide range of applications, including studies of corrosion, biological systems (e.g., cellular and enzyme activity, ion transport in channels of single cells), charge transport across liquid/liquid interfaces, electrochemical detection of single molecules, thin films and membranes. It is also a powerful tool for evaluation of the electrocatalytic activities of different materials for useful reactions, such as oxygen reduction and hydrogen oxidation.
