FYI:
Jed, you might want to add this to your library… http://www.sciencedirect.com/science/article/pii/S0040603112002742 Don’t know what this proves as far as Ni/H or Pd/D systems are concerned… there are significant differences: - they used alumina powder (Al2O3), and Al is atomic# 13 vs 28 for Ni - Al isn’t in the same region on the periodic chart; very different properties and electron configurations from the Ni/Pd/Pt column - they are using the oxide, which is a no-no in LENR - Couldn’t find anything so far about the H/D absorption properties of Al2O3, but doubt if they are anything like Pd So, bottom line, don’t think this paper proves anything about systems which use Ni or Pd… Note also that some of the authors are from a commercial entity, Coolescence LLC, so is this misinformation to slow the interest in LENR to give Cool-LLC time to catch up? -Mark ============ Origin of excess heat generated during loading Pd-impregnated alumina powder with deuterium and hydrogen O.

Abstract We studied heat production in Pd-impregnated alumina powder in the presence of hydrogen and deuterium gases, investigating claims of anomalous heat generated as a result of nuclear fusion, usually referred to as a low energy nuclear reaction (LENR). By selecting the water isotope used to fabricate the material and then varying the gas used for loading, we were able to influence the amount of heat released or consumed. We suggest that Pd in its nanoparticle form catalyzes hydrogen/deuterium (H/D) exchange reactions in the material. This hypothesis is supported by heat measurements, residual gas analysis (RGA) data, and calculations of energy available from H/D exchange reactions. Based on the results we conclude that the origin of the anomalous heat generated during deuterium loading of Pd-enriched alumina powder is chemical rather than nuclear. Highlights ► We studied heat produced by hydrogen and deuterium in Pd-impregnated alumina powder. ► Samples were fabricated using light and heavy water isotopes and varied the gas used for loading. ► Incorporation of hydrogen and deuterium influenced the amount of heat released or consumed. ► Pd nanoparticles appear to catalyze hydrogen/deuterium (H/D) exchange chemical reactions. ► Anomalous heating can be accounted for by chemical rather than nuclear reactions. ===================
