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 ...

The distribution of outermost shell electrons, known as valence electrons, of organic molecules was experimentally observed for the first time by a team led by Nagoya University in Japan. As 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, ...

Physicists have filled in some longtime blank spaces on the periodic table, calculating electron affinities of the lanthanides, a series of 15 elements known as rare earths. Physicists at Michigan ...

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 one-quintillionth-of-a-second lasing breakthrough could lead to next-generation X-ray technologies, improving imaging in medical, materials and quantum science. (Nanowerk News) Once only a part of ...

A valence electron in titanium oxide has been imaged at a resolution of 0.2 Angstroms using synchrotron X-ray diffraction and a new Fourier synthesis method that can determine the orbital states in ...

Metals consist of stacked layers of tightly packed, interacting atoms arranged in geometric patterns. Each of these atoms contains a small number of loosely held electrons in its outer shell. When ...

Physicists have been given the first glimpse of nuclear excitation by electron capture (NEEC), confirming theoretical predictions that were made more than 40 years ago. The global team – led by Jeff ...
