摘要

周围环境的变化如果传递到电子显微镜上，通常会被认为是降低图像质量的噪音。但事实上，"噪音 "包含了丰富的环境信息。这项工作报告了一个非常罕见的事件：在一次轻微地震中，我们在地震波的冲击下获取了经过像差校正的 HAADF-STEM 图像。通过分析这些图像，我们发现样品的漂移和振动是可以检测和量化的。尽管存在许多潜在的挑战，但这项工作证明了电子显微镜在探测和监测地震波时具有很高的空间分辨率，可能会在低频领域产生独特的应用。

Electron microscopy of seismic waves.

Changes in the surrounding environment, if transmitted to the electron microscope, are frequently perceived as noise that diminishes the quality of the images. However, in fact, 'noises' contain rich information about the environment. This work reports a very rare event where aberration-corrected HAADF-STEM images were acquired during the impact of seismic waves, resulted from a mild earthquake. By analysing these images, we found that the drift and vibration of the sample are detectable and quantifiable. Despite many potential challenges, this work demonstrates the utilisation of electron microscopes in detecting and monitoring seismic waves with high spatial resolution, which may lead to unique applications in the low-frequency regime.

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.
