An instrument that uses high-energy electrons to take "snapshots" of ultrafast chemical processes at the atomic and molecular level just got a major upgrade. Researchers have conducted the first ...
A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not randomly, but in a coordinated rhythm, twisting and untwisting in sync like ...
Ultrafast electron microscopy (UEM) and ultrafast electron diffraction (UED) employ extremely short electron pulses—ranging from picoseconds down to a few femtoseconds—to image and diffract samples ...
