The idea was to get the 'skin' of air to move accross the plate rather than sticking to it, at a molecular level. Apparently this worked really well - but it was a sort of non-comercial research thing.

I'm confused about the tubes - in the HWLabs link I posted they clearly said that the mixed metals problem was resolved by the nano-coating. But Skinnee says they're not alu in the water path so I guess I sit corrected
There was an update to that HWlabs article that said it's unknown. If Skinnee says there's none then there's none. Plus, why would they go to all the trouble and then make this mistake.

Also, the phenomenon of water 'sticking' to the sides of the radiator is due to a fluid boundary layer. To increase heat transfer you'd want to reduce the boundary layer. Here's a decent primer with history on it by J.D. Anderson Jr. He's written a number of good fluids and aerodynamics books. I have 4 of his books on my book shelf.
