Pd reactions possible at lower temps than Ni ------yes, exactly. However the reduction of the energy of vacancy of formation is also a good thing. Cu in Ni, Au or Ag in Pd, Sn in Ti,..... My understanding (as limited as it is) is that you need the phonon capability for the heat to leave the reaction areas and you need the vacancies to shuttle the H/D to and from where ever things are happening. (although I still think that there is a fair chance that the vacancies themselves may be the active site- that is vacancies with specific properties).

Maybe anomalous heat is a function of transition thru Debye temp and those experiments extracting heat provide repeated opportunities to make this transition at a higher rate. Fran
