Atomically-resolved dynamics and ultrafast high-resolution imaging

基于超短电子爆发的使用，Germán Sciainis小组开发了紧凑的超快相机，能够以原子分辨率拍摄动态现象和单个生物分子。仅仅在大约50年前，过渡态、键断裂和键形成事件被认为是不可测量的快。如今，我们已经达到了观测原子运动所需的空间（100亿分之一米）和时间（10万亿分之一秒）分辨率，从而对与物理、化学和生物学相关的动力学过程有了最基本的了解。

Based on the use of ultrashort electron bursts, Germán Sciainis group develops compact ultrafast cameras that are able to film dynamical phenomena and single bio-molecules with atomic resolution. Only about 50 years ago, transition states, bond breaking and bond formation events were thought to be immeasurably fast. Nowadays, we have reached the spatial (one ten-billionth of a meter) and temporal (one ten-trillionth of one second) resolutions required to observe atoms in motion, providing the most fundamental understanding of dynamical processes relevant to physics, chemistry, and biology.
