Iridium is a rare and expensive corrosion-resistant metal. ... This layer of iridium forms the Cretaceous-Paleogene boundary (formerly known as the Cretaceous-Tertiary boundary).

This research highlights the role of NHC SAMs in dual-layer coatings, providing superior corrosion protection for iron foils ...

This was the iridium layer. Here on the bank of the Brazos, I was holding microscopic pieces of the asteroid that killed the dinosaurs– fragments from the event that gave mammals a chance to ...
