One other post-script. Some people think that Fleischmann is misinformed about the J-M material, and it could not be their standard filter palladium, because that has too much silver in it to work well. Silver does prevent loading, but on the other hand, the people at BARC did report a

Pd is FCC at 389 pm. Pd atom radius is 137 pm (interesting number :-). This leaves 115 pm which allows the 102 pm NH3 molecule ideal for structuring but is challenging for the 188 pm Ar. I'm gonna sleep on this. BTW, what is the Van der Waals radius of deuterium? (too lazy to look it up now.)

I would bet, if you could grow single crystal Pd ( in a NH3 atmosphere), it would load quickly. And if you modulate it with a 26 Mhz signal (lambda = unit cell length), you could have controlled CF. Or not. Terry On Wed, Sep 9, 2009 at 7:04 PM, Terry Blanton hohlr...@gmail.com wrote: Pd is

Let me add a post-script. Since 2000, the ENEA researchers have put a lot of effort into understanding and fabricating palladium. They have done a good job. I have not made a rigorous comparison, but I think their material now rivals the best J-M material from the IMRA program. It puts out about
