Researchers have discovered how to design and place single-photon sources at the atomic scale inside ultrathin 2D materials, ...

(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.

Water (H₂O): Oxygen shares one electron with each of the two hydrogen atoms. Each hydrogen atom contributes one electron, resulting in oxygen having a total of 8 electrons in its valence shell (2 from ...
