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 ...

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 ...

Researchers at the European XFEL have made major progress in understanding how light interacts with matter at the quantum level after they achieved a 100-fold boost in photoionization efficiency. The ...

Visualization of the nano-world is a key component in many modern academic institutions. However, to harness the power of this expansive technique, as well as other essentials of cutting-edge research ...

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 ...
