A newly developed laser technology has enabled physicists to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of ...

A study suggests atoms can bond not only with electrons in their outer shells, but also via those in their supposedly sacrosanct inner shells Most of us learned in high school chemistry class that ...

The heavy metal uranium is, besides its radioactive reputation, known for its intricate chemistry and diverse bonding behaviors. Now, an international team of scientists utilized synchrotron light at ...

Hollow atoms are special atoms with multiple missing electrons in their inner shells, while their outer shells are still fully or partially filled with electrons. Studying the production mechanisms, ...

In addition to adding strength, this design allows the structure to use its crack patterns to minimize damage into the inner shell. Ling Li, an assistant professor in mechanical engineering at ...
