Copper's oxygen-rich early oxidation layer could inform catalyst design and nuclear waste storage

Copper roofs lose their reddish color over time because a pale green layer of copper oxide forms on their surface, protecting the roof from further corrosion for many years. But what exactly happens during the first steps of this process? Might it even be possible to stop it? Thi This story matters for Science & Discovery readers tracking inventors. Reported by phys.org.
