Animals that produce their own light source, through an internal chemical reaction, are one of the many wonders of nature – ...

Introducing nanoparticles of aluminium, using surface plasmonics, where light binds to electrons, Fresnel would create what he called Hard Light—a microscopic material capable of building any ...
