Owing to the absence of dislocation defects and grain boundaries, the amorphous structure of metallic glass possesses superior mechanical properties compared to its crystalline counterparts. Koji Nakayama and co‐workers present on p. 872 a method that is capable of producing metallic glass nanowires. The image shows that the free end wire in the center oscillates like a sine‐wave pattern implying extremely high elasticity. The authors have succeeded to measure these mechanical properties at the nanoscale.
