摘要

液相（或液胞）透射电子显微镜（TEM）已成为在纳米或原子级别现场研究各种化学过程的强大平台。用于成像的电子束也会对化学过程产生扰动。因此，人们担心在液胞中观察到的现象可能会偏离真实世界的过程。为了克服电子束引起的问题，人们已经开发了一些策略。本文概述了电子束效应，并讨论了在液胞 TEM 中研究纳米级材料的成核、生长和自组装（通常使用电子束引发反应）以及对电子束高度敏感的电化学反应的各种策略。

Strategies to overcome electron-beam issues in liquid phase TEM: Study of chemical processes

Liquid phase (or liquid cell) transmission electron microscopy (TEM) has become a powerful platform for in situ investigation of various chemical processes at the nanometer or atomic level. The electron beam for imaging can also induce perturbation to the chemical processes. Thus, it has been a concern that the observed phenomena in a liquid cell could deviate from the real-world processes. Strategies have been developed to overcome the electron-beam-induced issues. This article provides an overview of the electron-beam effects, and discusses various strategies in liquid cell TEM study of nucleation, growth, and self-assembly of nanoscale materials, where an electron beam is often used to initiate the reactions, and highly electron-beam-sensitive electrochemical reactions.

期刊介绍： MRS Bulletin is one of the most widely recognized and highly respected publications in advanced materials research. Each month, the Bulletin provides a comprehensive overview of a specific materials theme, along with industry and policy developments, and MRS and materials-community news and events. Written by leading experts, the overview articles are useful references for specialists, but are also presented at a level understandable to a broad scientific audience.
