It will be given an overview of main progresses obtained, since March 1989, during the studies (experimental and/or theoretical) on thermal and/or nuclear anomalies observed and/or hypothesized due to the close interaction of hydrogen isotopes (Hydrogen, Deuterium) with some specific materials (mainly Palladium, Nickel) pure and/or alloyed, and that were forced to proper non-equilibrium conditions.
From experimental point of view, will be shortly quoted and discussed the main experiments that made a significant progress in respect to previous one. Most of the experiments were made using electrolytic environment at moderate temperatures (20-50°C). Recently, become more and more common the use of gas environments and quite large temperatures (usually 200-400°C, up to 500-900°C in explorative test), proper for even electrical energy generation. The first experiment at high temperatures (350°C), fully successful, using gaseous deuterium with palladium tube, was made by NASA Scientist just nine months after the Fleischmann-Pons announcement. Sadly, such key result wasn’t made public for over 15 years.
We recall that specific nanostructures are playing a crucial role both in basic studies and, even claimed recently (but not independently verified), technological/industrial applications.
From the theoretical point of view, they will be quoted and discussed few of the several models (over 140) up to now introduced that tried to explain some of the several anomalies experimentally found. Some words will be spent to introduce a recent model, based on the weak interaction, that claims to explain almost ALL the anomalous effects up to now experimentally found.
