A smooth surface might seem most likely to repel water, but scientists found that a rough surface, with ridges, for example, worked better.


Hi All,
I'm sure many of you saw this story.  It's a very cool example of nano molecular architecture that extends upward in scale that involves nasturtiums and lotus leaves ( and probably many other plants as well).  It might be very cool to connect the physical behavior of water, which is strongly driven by its molecular polarity, with the structure of leaves and other surfaces that "wet" or don't.
