in the old paper, Dr. Mizuno seems to say that sputtering method would give less XH? Can we check this ?
It remains an important point for replications.
That is one of the old reactors. The Pd was deposited on the Ni with glow discharge during the test. That method is no longer used. With the newer reactor, the Pd is deposited by rubbing, before the test. That takes much less time. Weeks or months less time.
