Electrons oscillate around the nucleus of an atom on extremely short timescales, typically completing a cycle in just a few hundred attoseconds. Because of their ultrafast motions, directly observing ...

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 ...

Using SLAC's instrument for ultrafast electron diffraction (MeV-UED), one of the lab's world-leading tools for ultrafast science, researchers discovered how an ultrathin material can circularly ...

During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical products. This process entails the movement of both electrons (i.e., negatively ...

Transient reflectance of multilayer MoS₂ (a) shows prompt electronic response, while ultrafast electron diffraction (b-c) reveals delayed lattice heating, enabling quantitative modeling of energy ...

Electrons are incredibly fast. Because of their ultrafast motions, directly observing their behavior has been challenging. Now researchers have suggested a new method to make visualizing electron ...

Schematic diagram and photograph showing the ultrafast transmission electron microscopy integrated with transient optical spectroscopy capability, enabling co-registered measurements of electronic and ...

(Nanowerk News) Imagine being able to watch the inner workings of a chemical reaction or a material as it changes and reacts to its environment – that's the sort of thing researchers can do with a ...

Could you start by explaining your background in crystallography and how you began using the Rigaku Synergy-ED system? Fraser: I began my journey into crystallography at the University of Edinburgh in ...
