Why gold never tarnishes has finally been explained
SMRTR summary
Researchers at Tulane University discovered that gold resists tarnishing not just because of its chemistry, but because surface atoms rearrange themselves into protective patterns that reduce oxygen reactions by a billion to a trillion times. This insight could help scientists design better gold-based catalysts for clean energy and industrial manufacturing.
