Scientists have cracked a long-standing chemistry problem, creating nanocrystals from tough metal nitrides that were previously extremely difficult to produce at this scale. The breakthrough could turn familiar materials used in LEDs, implants, and superconductors into building blocks for flexible electronics, printable devices, and other technologies. from Latest Science News -- ScienceDaily https://ift.tt/FaB4Q6e
