How do organic solar cells work on the inside? The answer lies in structures far too small to see—and difficult to access ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

Visualizing the rearrangement of atoms in a wide range of molecular and condensed-matter systems requires resolving picometre displacements on a 10-fs timescale, which is achievable using pump–probe ...

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 ...

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 ...

IN 1924, Prince Louis de Broglie put forward the thesis that all material particles, and in particular electrons, have properties analogous to those of a train of waves. This view, which is now ...

Although Danish physicist Niels Bohr's atomic model was tremendously successful, and experiments by Moseley and Franck-Hertz strongly supported it, the bold hypotheses of the Bohr model were just that ...
