... Meanwhile, perhaps a discussion of the unique condition that is required to form in Pd before LENR can occur and how the burnishing process can cause such a condition would be useful.
I posted to vortex-l about the possibility that the palladium need not be present. This assumes, rightly or wrongly, that it is the presence of calcium on the nickel that is a key factor - independent of the presence of palladium.
A complicating thought: The burnishing embeds the calcium. Leading to other questions: Must burnishing be done with different metals? How much calcium can be rubbed into nickel (or palladium)?
So the preparation process you are writing about involves "cleaning", "abrading", and "burnishing". Does it involve micro or nano alloying?
May your lead an interesting life.
