    The synthesis of high-entropy alloy nanoparticles (HEA-NPs) — small particles each containing multiple principal metal elements — typically requires extreme conditions to ensure adequate mixing of constituents. Innovative experiments show that the liquid metal can act as a mixing reservoir to facilitate the synthesis of a diverse range of such nanoparticles in mild conditions.

    Electric motors convert electrical energy into mechanical motion. A molecular motor has been designed in which electricity drives redox reaction cycles that lead to the movement of two small rings around a large circular loop. The small rings make one full revolution around the loop for every two redox cycles.
