Bruce Ravel is shown at the Beamline for Materials Measurement. Despite its rarity, promethium has a few interesting applications, including manufacturing specialized glow-in-the-dark paint, radiation ...

Conceptual art shows the rare earth element promethium in a vial surrounded by an organic ligand. ORNL scientists have discovered hidden features of promethium, opening a pathway for research into ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Researchers wanted to find out if it was possible to make a molecule that could selectively bind to metal cations in the middle of the lanthanide series. The team provided a proof-of-principle in a ...

Notably, the team provided the first demonstration of a feature of lanthanide contraction in solution for the whole lanthanide series, including promethium, atomic number 61. Lanthanide contraction is ...
