Physicists have finally done what once sounded like science fiction: they have read the X-ray “fingerprint” of a single atom, isolating the signal of one of nature’s smallest building blocks from the ...

Single-atom catalysts (SACs) are materials consisting of individual metal atoms dispersed on a substrate (i.e., supporting surface). Recent studies have highlighted the promise of these catalysts for ...

(Nanowerk Spotlight) At the scale of individual atoms, materials behave in ways that defy everyday intuition. Stretch a metal wire by a few micrometers and its resistance changes only slightly.

Heterocycles, molecular rings found in many pharmaceuticals, have a reputation for stubbornly resisting modification. That is, in a heterocycle, heteroatoms of one type aren’t easily swapped for ...
