A solid-state "atomic channel" for separating rare earth elements
Researchers have developed a new, cleaner method for separating rare earth elements using manganese oxide atomic channels. This electrochemical process avoids the toxic chemicals traditionally required for purification, potentially improving the sustainability of manufacturing high-tech components.
Why it matters
Rare earth elements are critical for modern technology like EVs and medical devices; cleaner extraction methods are essential for reducing the environmental impact of the supply chain.
