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 ...

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 ...

Combines a high-resolution field emission scanning electron microscope with gallium focused ion column capable of ion milling material at the nanoscale.

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 ...
