Precious metals Memes

Museum displays of precious metals are the ultimate tease for chemists. Two samples of palladium just sitting there, begging to be used as catalysts for cross-coupling reactions, and all we can do is stare through the glass. The bottom image captures that primal chemist urge to create a "reducing environment" — a chemistry double entendre referring both to the reduction reactions palladium catalyzes and the threatening tone of making the environment "so reducing" that those samples might just... disappear into someone's lab coat. Precious metal theft: the only crime where you calculate the yield percentage afterward.
