Research suggests some metals’ semicore electrons may be more active on Earth’s surface than previously thought.

You probably learned in high school chemistry class that core electrons don't participate in chemical bonding.They're thought to be ...

Inner core electrons are expected to have a peanut like wavefunction as is shown for Si 2 s electrons (right). In the C-C bond, however, the C1s electrons form a torus like feature of opposite ...

AES operates on the principle of the Auger effect, named after the French physicist Pierre Auger. When a material's surface is bombarded with a beam of high-energy electrons or photons, it causes the ...

XPS relies on the photoelectric effect, where irradiating a material with X-rays causes the emission of core electrons. The kinetic energy of these emitted electrons is measured, which can be directly ...

For the first time, scientists have used ultrafast X-ray flashes to take a direct image of a single electron as it moved during a chemical reaction. In the new study, published Aug. 20 in the journal ...
