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, ...

Like Earth, Mars was formed about 4.5 billion years ago, but its early surface was very different than today's. Mars' surface then had high rates of meteorite and asteroid impacts from the period ...

Pushing the known limits of lanthanide oxidation, chemists have isolated praseodymium (Pr) in the +5 oxidation state. While Pr 5+ compounds have been observed in the gas phase and in noble gas matrix ...

A newly developed pentanuclear iron complex can offer an efficient, stable, and cost-effective solution for water oxidation. By electrochemically polymerizing the complex, researchers have obtained a ...

A unified copper-based catalyst platform featuring multivalent r-CuO nanorods for cathodic nitrate reduction (FE NH3% =96.8%) and pristine CuO nanorods for anodic glycerol oxidation (FE Formate% =93%) ...
