Using short laser pulses, researchers have imaged the exact moment an ammonia molecule bends and sheds a hydrogen atom.

During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical ...

Electrons oscillate around the nucleus of an atom on extremely short timescales, typically completing a cycle in just a few ...

Using a high-speed "electron camera" at the Department of Energy's SLAC National Accelerator Laboratory, scientists have simultaneously captured the movements of electrons and nuclei in a molecule ...

Researchers have developed a new and improved version of electron diffraction that offers advanced and unique experimental instrumentation for studying particle acceleration to researchers from all ...

Twisted photonics: A bilayer of molybdenum trioxide supports highly unusual light propagation along straight paths when the two layers are rotated with respect to each other at the photonic magic ...

Recent advances in electron microscopy and diffraction have increasingly focused on capturing dynamical processes at unprecedented temporal resolutions. Ultrafast electron microscopy and diffraction ...

PASADENA, Calif.—Techniques recently invented by researchers at the California Institute of Technology (Caltech)—which allow the real-time, real-space visualization of fleeting changes in the ...

In 1933 Peter Kapitza and Paul Dirac predicted that a standing light wave would act as a ‘light grating’ that could diffract electrons. But light interacts only weakly with electrons, and early ...

Using SLAC's high-speed 'electron camera,' scientists simultaneously captured the movements of electrons and nuclei in a light-excited molecule. This marks the first time this has been done with ...
