How does gold keep its glitter? Researchers uncover why it resists tarnish

Phys · · 485 words · By Tulane University

Researchers from Tulane University have discovered that gold's resistance to tarnishing is partly due to the natural rearrangement of surface atoms into protective patterns. This finding provides a new understanding of gold's stability and suggests potential methods for improving gold-based catalysts in industrial applications.
