Display MoreTakahashi et al considered the possibility of heat from the reduction of oxides in the calcined powder.
They found that the heat evolved remained constant whether the powder was calcined 1,2 or 3 times
If the heat generation by PNZ6 at RT is from reduction of calcined sample (namely from formation of D2O water by D2 + O reactions),we should have observed very increased integrated heat and “apparent” increase of loading ratio values.
Evidently, it is not the case. We can conclude that reduction process is negligibly small for D (H) absorption runs of PNZtype samples.
Since specific reaction energies are observed as almost same values (0.55 eV/D in average),
microscopic reaction mechanism seems common in three samples.
We regard that D-absorption is into Ni nano-cores mostly because of 1/10 minor Pd content.
About 0.55 eV/D for nickel is considerably large exothermic value at RT.

Thanks for posting this. Many do not realize you frequently communicate (go straight to the source) with the Japanese researchers. Maybe there is a lesson here for skeptics: ask first before inserting foot in mouth?
Yes, it does appear from your post that Takahashi and team, did in fact take into consideration all possibilities before concluding AHE. Including the hot debate item introduced by Ascoli in this thread.
