US scientists use atomic channels to purify rare earths without toxic solvents
SMRTR summary
US scientists developed a cleaner way to purify rare earth elements — critical for EV motors and smartphones — using a layered manganese oxide material whose tiny water-filled channels sort elements by size. Adding magnesium ions boosted neodymium purity to 97% in just two cycles, eliminating the need for toxic solvents.
