wow, to be honest im having a real hard time finding anything realavent. I heard about it when i was visiting the technical university of braunschweig in germany. they were studying the increase in thermal transfer vs the pressure drop for use in heat exchangers. basically you acid etch the surface of the material into a structured pattern, pyramids, whatever, you think will get the best transfer with minimal pressure drop. the structure is so small it pretty much just feels a bit rough to the touch. in order to see what the texture looks like, a magnifying instrument must be used. sorry i dont have any pics or links.
