Penn Science Cafe with Eric Schelter

Despite their ubiquity in consumer electronics, rare-earth metals are, as their name suggests, hard to come by. Mining and purifying them is an expensive, labor-intensive and ecologically devastating process. Schelter and his colleagues have devised a new, simple method for separating the two rare-earth metals that are commonly found in things like wind turbine generators and power tool motors, enabling them to be recycled into new products.
