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 ...

Explore the fascinating world of atoms in this 3D animated video. Discover the structure of atoms, including protons, neutrons, and electrons, as well as their significance in the universe.

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 ...

Scientists have finally glimpsed chemistry at its smallest level after capturing the first-ever X-ray of a single atom. Atoms are the tiniest particles in our universe, and they're the basic ...

A 40-atom gold nanocluster breaks from gold's signature dense packing, forming square atomic planes with a central channel that accelerates electron relaxation about 80x.

In 1923, the year C&EN was born, Gilbert N. Lewis of the University of California, Berkeley, published a book titled “Valence and the Structure of Atoms and Molecules.” In the text, Lewis laid out the ...

The big idea of atomic theory is that, at some smallest, fundamental level, the matter that makes up everything can be divided no further. Those ultimate building blocks would be literally ἄ-τομος, or ...

Why is our Universe the way it is, and not some other way? There are only three things that make it so: the laws of nature themselves, the fundamental constants governing reality, and the initial ...

The search for extraterrestrial life is one of the most exciting frontiers in astronomy, and the recent detection of a potential biosignature in the atmosphere of Venus has now raised the possibility ...
