Old thinking was that gold, while good for jewelry, was not of much use for chemists because it is relatively nonreactive. That changed a decade ago when scientists hit a rich vein of discoveries revealing that this noble metal, when structured into nanometer-sized particles, can speed up chemical reactions important in mitigating environmental pollutants and producing hard-to-make specialty chemicals.
The Department of Energy’s Oak Ridge National Laboratory has developed a technology leading to more secure seals on containers filled with nuclear material. The technology uses a light source of entangled photons to verify the continuity of a fiber-based seal. E...
