The link between chemistry and Lenr remains to be proven. I know that most of the field connects chemistry to Lenr.
Personally, I think it wasted a lot of time focusing on this pseudo link.
For example, where is the chemistry in the Iwamura's multilayers ?
The company Catalytica Associates, Inc., Micheal Boudart founded, patented several processes for the production of urethanes. Looks like similar stuff that Shell developed as Shell S-105 catalyst. Something Holmlid used to produce UDD and UDH.
