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.

基于超短电子爆发的使用，GermánSciainis组开发了紧凑的超快摄像机，这些相机能够以原子分辨率拍摄动态现象和单个生物分子。仅在大约50年前，过渡状态，债券断裂和债券形成事件被认为是无可估量的。如今，我们已经达到了观察运动中原子所需的空间（一米十亿分之一）和临时（一千万秒的一秒钟）决议，从而提供了对与物理，化学和生物学相关的动态过程的最基本理解。
