Tulane University researchers reveal gold's atomic oxidation resistance

Researchers at Tulane University in New Orleans have uncovered new insights into why gold is highly resistant to oxidation at the atomic level. The study reveals that gold atoms on a surface self-organize into a unique hexagonal structure.

This specific arrangement creates a stable surface that makes it significantly more difficult for oxygen molecules to break apart into individual oxygen atoms. This process is essential for the oxidation reaction to occur, and the hexagonal structure effectively prevents it, explaining the metal's characteristic durability.
