Research news on rare earth elements

Rare earth elements (REEs) are a group of 17 chemically similar metallic elements comprising the lanthanides (lanthanum to lutetium) plus scandium and yttrium, characterized by partially filled 4f electron shells that confer unique magnetic, optical, and catalytic properties. In geochemistry and materials science, REEs are typically divided into light and heavy subgroups based on atomic number and ionic radius, which control partitioning behavior, coordination chemistry, and lattice incorporation in minerals. Their coherent but subtly fractionated behavior in magmatic, metamorphic, and sedimentary processes makes REE patterns powerful tracers of source composition, redox conditions, and fluid–rock interaction in Earth and planetary systems.

How defects make permanent magnets even more efficient

Rare-earth magnets are essential for electric motors in vehicles, drones, and trains, forming the backbone of modern, environmentally friendly mobility. These are not simple blocks of metal, but carefully engineered materials ...

Beetles block mining of Europe's biggest rare earths deposit

As Europe seeks to curb its dependence on China for rare earths, plans to mine the continent's biggest deposit have hit a roadblock over fears that mining operations could harm endangered beetles, mosses and mushrooms.

Chinese team finds a fern that makes rare earth elements

Scientists have discovered a fern from South China that naturally forms tiny crystals containing rare earth elements (REEs). This breakthrough opens the door to a promising new way of "green mining" of these minerals called ...

Sulfated yeast rises to the challenge facing rare earth metals

Ever wonder what happens to those old, broken electronics after tossing them? How about how new ones are being produced despite dwindling resources? The seemingly endless supply of gadgets hides an increasingly critical problem: ...
