Here's a link to my latest article in The Motley Fool. It's entitled: DuPont: The Truth Helps Nanotech. It reviews how DuPont is applying the painful lessons it learned from its recent run-in with the EPA regarding PFOC (i.e. the $16 million fine) to nanotechnology. It is just one of the reasons I'm bullish on DuPont's long-term prospects. (Full Disclosure: I don't own any DuPont stock at this time.)
