Ah. "tubercles" instead of tubules . Thanks Bob
From: Bob Higgins Rossi has stated that he starts with 10 micron sized particles (since identified as a nickel powder produced from the carbonyl process), adds a catalyst (widely believed to be a nanopowder of some kind), and processes the mix "in a way that leads to amplified tubercles on the surface". A search of tubules will not find the reference, he used "tubercles". I have replicated the growth of tubercles by doing just what Rossi described.
