Rust - pretty unpopular

My latest podcast for the Royal Society of Chemistry takes a look at a compound that doesn't have many of us cheering - in fact it's pretty unpopular all round. I'm talking about rust. We may rather like the fetching patina of some metal oxides, but no one cheers when rust appears - especially if it's on a car.

Even so, that doesn't mean that rust isn't interesting stuff from the chemical viewpoint. Quite the reverse. So pop along to the RSC compounds site - or if you've five minutes to spare, click to to have a listen to my podcast on rust.
