The Takeaway
We usually see atoms as static dots in textbook diagrams, but this new technique uses high-speed electron microscopy and AI to watch them move in their natural liquid environment. It reveals that supposedly solid crystals are actually constantly flickering and changing their structure in response to their surroundings.
From the abstract
Atomic structures of nanomaterials are inherently dynamic, continuously reshaped through interactions with chemical species and external stimuli. Such dynamics are further amplified as the size and dimensionality of nanomaterials are reduced. Despite advances in analytical methods, it remains challenging to capture structural dynamics of nanomaterials in reactive environments with both atomic spatial resolution and commensurate temporal resolution. Here, we directly visualize atomic-scale dynami
