Interesting. I don't have access to the full text of the paper, but I'm surprised the platinum-doped gallium doesn't form a protective oxide shell, like pure gallium does. Perhaps this depends on having very small particles? Or does the platinum just stabilize the surface chemistry against oxidation?
