I met a scientist researching rust and the rust process. It was a little over my head but if you find new tools being sold that don't rust, I'm sure it will be her doing.
Rust actually sounds like a very interesting topic if you think about it a bit.
Fun fact, did you know that you are rusting, right now? Breathing is rusting, specifically it's oxidisation of iron in your blood. It's how your blood carries oxygen around your body.
I did not! But I definitely feel rusty come to think of it.
I know how you feel.
Does that mean that if we took something rusty and put it in an environment without oxygen it would start to release oxygen from the rust?
There's another factor involved to convince the iron to let go of the oxygen, so if we mimicked that as well, then yes. It's just chemical reactions.
I thought it was just (or mostly) partial pressure of O2 when it comes to hemoglobin? It's been about 15 years since I was in school so I might remember wrong.
"Carbon dioxide increases hydrogen ion concentration and lowers tissue pH. As a consequence, hemoglobin’s affinity for oxygen decreases and oxygen release to tissues is facilitated."
