You probably learned in high school chemistry class that core electrons don't participate in chemical bonding. They're thought to be too deep inside an atom and close to the nucleus to meaningfully ...

Conventional electron spectroscopy is an established one-electron-at-the-time method for revealing the electronic structure and dynamics of either valence or inner shell ionized systems. By combining ...

Fused-ring electron acceptors (FREAs) have a donor–acceptor–donor structure comprising an electron-donating fused-ring core, electron-accepting end groups, π-bridges and side chains. FREAs possess ...

Speed matters. When an X-ray photon excites an atom or ion, making a core electron jump onto a higher energy level, a short-lived window of opportunity opens. For just a few femtoseconds, before an ...

The Electron Microscopy Core Facility includes three scanning electron microscopes (SEM), an aberration-corrected atomic resolution scanning transmission electron microscope (STEM), and a focused ion ...

A University at Buffalo study provides new insights about core electrons, including their role in the B1-B2 transition that sees a compound's atomic crystal structure rearrange from an octahedral ...
