One of the many possible routes to next-gen materials— ones that enable new advances in data storage, electronic devices, and lighter and stronger structural building materials— is through supercooling of metals into a category of alloys called ‘metallic glass,’ with no regular or crystalline pattern of atomic structure (scientists call it “amorphous”). Unlike common or window glass, however, these metallic glasses are excellent electrical conductors, making them promising for all sorts of tech applications.
