A solid-state "atomic channel" for separating rare earth elements
SMRTR summary
Separating rare earth elements — critical for EV motors, LEDs, and MRI machines — has long required toxic chemicals. Researchers at UChicago, Northwestern, and Argonne developed a cleaner method using layered manganese oxide channels that sort elements by water shell size, achieving 97% pure neodymium using only water and electricity.
