Bill, I only know this work done at Laser Zentrum Hannover (Germany), see "surface modification": http://www.laser-zentrum- hannover.de/en/fields_of_work/material_processing/microtechnology/index.php It seems to be a kind of lotus effect by controlling the contact area between solid and liquid.

I do not see how it could work unless they are talking laser in combination with a silane to reconstruct the surface layer. What are you trying to do? If there is a commercial use at the end of the tunnel we could do some free samples for you. Bill Moffat, CEO Yield Engineering Systems, Inc.
