If the atom in question is in a small particle on the surface of a piece of silicon, the result is what is known as a surface plasmon.

Nanophase can make them 50 nanometers wide, which renders the zinc oxide transparent no more white goop since each crystalline particle is small enough to allow harmless light to pass through.

FORBES: The Science of Small

Nanophase can make them as small as 50 nanometers wide, which renders the zinc oxide transparent no more white goop since each crystalline particle is small enough to allow harmless light to pass through.

This is especially true at very large and very small scales (think astronomy or particle physics), but also liminal spaces or large sociotechnical systems that cannot be experienced completely or directly (think cyberspace, but also large infrastructure systems like power grids, interstrate highway systems, etc.).

But one of the biggest reasons for Phoenix's high pollution levels is actually cattle ranches found south of the city, in Pinal County and vicinity.. "Those cattle ranches are contributing a lot of fine particle pollution to the small communities near them that are part of the Phoenix metro area, but also to the tribe adjacent to it, " says Nolen.

The frequency at which it happens is related to a small but significant difference between the mass of the particle and its antiparticle.
