The positions of all the atoms in a sample of a metallic glass have been measured experimentally — fulfilling a decades-old dream for glass scientists, and raising the prospect of fresh insight into ...

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, ...

Since their discovery in the 1950s, metallocenes—chemical compounds where a metal atom sits "sandwiched" between two carbon rings—have been at the heart of organometallic chemistry research, finding ...

The Bohr model, introduced by Danish physicist Niels Bohr in 1913, was a key step on the journey to understand atoms. Ancient Greek thinkers already believed that matter was composed of tiny basic ...

Researchers at the Kastler Brossel Laboratory in Paris have made the most precise measurement of one of the fundamental constants, called the fine-structure constant, providing physicists with a vital ...

Until now, atoms have never been imaged interacting freely in space, but a new technique known as non-resolved microscopy has changed that. MIT physicists were able to successfully capture images of ...

On target A new method for precisely moving columns of individual atoms within a material could give rise to exotic quantum ...

A team in Paris has made the most precise measurement yet of the fine-structure constant, killing hopes for a new force of nature. As fundamental constants go, the speed of light, c, enjoys all the ...
