Abstract

Liquid-phase transmission electron microscopy (LP-TEM) can be used with an electrochemical chip (e-chip) to observe electrochemical reactions in a liquid in situ. The design of electrodes on an e-chip fabricated using microelectromechanical system (MEMS) technology cannot be easily changed. Here, we report a newly designed e-chip and its fabrication process. Electrodes with a desired shape were fabricated with various metals via an additional step of vacuum deposition onto our e-chip with a shadow mask. For precise control of the electrochemical reactions in LP-TEM, optimization of the electrode shape and material is critical.

液相透射电镜电化学芯片的设计与制造。

液相透射电子显微镜（LP-TEM）可以与电化学芯片（e-chip）一起使用，原位观察液体中的电化学反应。使用微机电系统（MEMS）技术制造的电子芯片上的电极设计不容易改变。在此，我们报道了一种新设计的电子芯片及其制造工艺。通过使用荫罩在我们的电子芯片上进行额外的真空沉积步骤，用各种金属制造出具有所需形状的电极。为了精确控制LP-TEM中的电化学反应，电极形状和材料的优化至关重要。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
