ISS involves the bombardment of a surface with a beam of ions, typically noble gas ions like helium or neon, under vacuum conditions. When these ions collide with the sample surface, they are either ...

Plasmonic metasurfaces are emerging as two-dimensional (2D) metamaterials capable of manipulating light on the nanoscale with the possibility of being incorporated into optoelectronic devices.

Throughout the world ocean, animals congregate at certain depths. A new paper shows that, rather than consisting of a random mixture of animals, these deep-scattering layers contain discrete groups of ...
