Instead of a tempest in a teapot, imagine the cosmos in a canister. Scientists have performed experiments using nested, ...

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

Along with two other colleagues, they coauthored a sensational 1980 paper about the “iridium anomaly” — a 1-centimeter-thick (0.4-inch-thick) layer of sedimentary rock rich in iridium, an ...

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).
