Earlier I wrote some stuff based on a phone conversation with Mizuno:
The paper by Kitamura (. . . presented by Takahashi) described a
replication of Arata's older technique with the double structured
cathode (DS cathode) and Pd-black. The Pd black produced heat but it
also sintered, and then the performance degraded. This is the same
problem Arata experienced.
(I am a little disappointed to hear this was a replication of the
older technique. The newer zirconium material was designed partly to
avoid sintering.)
I now have more information. It turns out they reported two
experiments: a DS-cathode version and the Zr-Pd, using Zr-Pd from a
source other than the one Arata uses. They report success with both techniques.
For the Zr-Pd they used flow calorimetry. The flow rate is 6 cc/min
which seems far too low to me. It looks to me like they got ~180 mW
anomalous heat after the heat of formation of Pd-D finished.
The Pd-H runs are a pretty clean null, so perhaps they can measure
with 6 cc/min. I hope so, but I wish they would use a larger sample
to get more heat, and a higher flow rate.
