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 ...

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, ...
