At National Institute of Nuclear Physics, Frascati National Laboratories (INFN-LNF)-Italy, studies about Cold Fusion started on March 26, 1989. We found, since the beginning, that non-equilibrium situations are key-factors to get any “anomalous effect” (thermal/nuclear): mostly, they are forced reactions, not spontaneous. The present abstract is: A...

the improvements on Constantan-related experiments, started in 2011, in order to study the feasibility of new Nickel based alloys that are able to absorb proper amounts of Hydrogen (H2) and/or Deuterium (D2) and that have, in principle, some possibility to generate anomalous thermal effects at temperatures >100°C.

Langmuir measured that the density of Hydrogen atoms adsorbed onto the surface of a glass bulb (presumably of type borosilicate) kept at low temperature (about 90 K) is of the order of 10 15 atoms/cm 2 . In his experiments, the dissociation was obtained through a hot W filament in H2 atmosphere and the fraction of dissociated molecules depended on pressure and temperature: lower the pressure and higher the temperature, larger the fraction ( [5], [6]). In our experiments the effective surface of each (small) sheath is larger than 1 m 2 . ...
