A longstanding mystery of the periodic table involves a group of unique elements called lanthanides. Also known as rare earth elements, or REEs, these silvery-white metals are challenging to isolate, ...

Mayara da Silva Santos, doctoral candidate at the University of Freiburg's Institute of Physics, has discovered a new oxidation state of rhodium. This chemical element is one of the most catalytically ...

Transition metals in high or unusual oxidation states might play an important role as catalysts or reaction intermediates in chemical reactions. Because transition metals are already well ...

Chemists have discovered a new oxidation state of rhodium. This chemical element is one of the most catalytically important platinum-group metals and is used, for example, in catalytic converters for ...
