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 ...

Researchers at the University of New South Wales (UNSW), alongside those from the Université de Sherbrooke in Quebec and Aalto University in Finland, have announced they have used artificial atoms in ...

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 ...

Many of us learned in high school chemistry that the electrons around an atomic nucleus occupy different energy levels. The low-energy levels are known as the inner electron shells, and the ...

X-rays, a type of electromagnetic radiation with wavelengths from 0.01 to 10 nanometers, pack enough energy to pierce materials and interact with inner-shell electrons. 1 When they hit a sample, ...

The heavy metal uranium is, besides its radioactive reputation, known for its intricate chemistry and diverse bonding behaviors. Scientists utilized synchrotron light to explore the unique properties ...
