(Phys.org)—Scientists have fabricated a superlattice of single-atom magnets on graphene with a density of 115 terabits per square inch, suggesting that the configuration could lead to next-generation storage media.
Japanese high-tech firm Hitachi Wednesday unveiled an electric motor that does not use "rare earths", aiming to cut costs and reduce dependence on imports of the scarce minerals from China.
