The rare-earth metals used to build our phones, electric vehicles and renewable energy systems are extraordinarily difficult to recover and recycle. Traditional extraction methods are slow and chemically intensive and often yield impure results. Researchers Mercedes Taylor and Michael Baptiste have designed a molecule that solves this problem by self-assembling around rare-earth ions to selectively bind and separate them from complex mixtures. The process is rapid, recyclable and precise, with the potential to build a more sustainable and reliable supply chain to support clean energy infrastructure.
