This can be read in conjunction with
http://en.wikipedia.org/wiki/2DEG and the Lawandy paper, to understand that hydrogen spillover is probably in the class of 2D reactions, at the outset. There could easily be a strong topological basis for robust LENR. Interfacial layers, boundary layers, Blasius and Stokes layers are all expanding the notion that "2D is really more the 2D" in a strictly defined way. The further analogy in the progression, from the art world, is "bas relief" which is 3D made to look like 2D. In practice, there is a progression from 2D to 3D up to a few nanometers, rather than an abrupt change, and it is fascinating that the interface seems to make the big 'qualitative, or quantum' shift at or above the Forster radius upper limit 10-12 nm, but below that many processes look more like 2D.
