They are growing Buckyball on the surface so that would be very similar to your in effect to that paper you quoted.
Good luck with the FM-200, be careful with the pressure in your loop if it boils that low. I want to see some pics of this set up, it sounds pretty bad a$$
That will be interesting to know about the graphene......as regards my next build......I'm going to make a video log when I finally get going....but first I've to get an out house to do it in...as you say could be dangerous if things went wrong so won't do it in the house.
PS...regards the paper I linked to.....its describing several surface modifications only one of which was relating to nano pillars......it also describes modifying the hydrophillic nature of the solid surface.....here's a direct lift from the conclusion.

groups leads to an increase in the thermal conductance of the
interface by a factor varying from 1.8 to 3.2 times"Edited by technogiant - 3/27/13 at 3:28pm
