BUFFALO, N.Y. — 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 ...

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 ...

Scientists use European XFEL's fast X-ray pulses for doubly resonant ionisation of krypton. (Nanowerk News) Speed matters. When an X-ray photon excites an atom or ion, making a core electron jump onto ...

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

Uni-President Enterprises has been granted a patent for a small-molecule electron donor material with an electron-deficient heterocyclic core for use in solar cells. The material features a unique A-D ...

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 ...
