A solid-state “atomic channel” for separating rare earth elements

# Summary University of Chicago researchers have developed a cleaner method to separate rare earth elements using layered manganese oxide with atomic channels, eliminating the need for toxic chemicals traditionally used in this purification process. The electrochemical intercalation technique works in water without organic solvents and is competitive with existing separation methods while being more environmentally friendly. This breakthrough could significantly improve rare earth element processing for technologies like electric motors, LED lights, and MRI machines.
