Interesting to see they observed Rossi's granted US patent without mentioning him.
In addition it is remarkable to see Mizuno's direction towards nickel nano particles on Pd. In the past he used nickel nano-structures on nickel by bombarding smooth nickel surface with protons. At that time I made a suggestion to him to use Argon, as generally is used by nickel sputtering methods, to be more efficient to produce nickel nano-structures, which he tried but did not have a suitable HV power supply available at the time. Now, it looks like he is applying nickel sputtering on PD surfaces.
Nickel will have a different Deuterium absorption rate/ratio as Palladium. Since Deuterium absorption will cause metal lattices to expand (can be up to 120% of the original volume), local nano-scale mechanical tension will be created, possibly followed by nano-cracks (Ed Storms will like this).
This also shows some similarities with the Constantan wire concept of Francesco Celani. Constantan alloys have nickel and copper lattice clusters sitting next to each other, but each have their own Hydrogen/Deuterium absoption rates/ratios.
Thanks for the translation effort Jed, very valuable.
