Experimental Results on Sub-Micro Structured Cu-Ni Alloys...

Ho aspettato che passasse la mezzanotte per pubblicare questo post, altrimenti qualche bontempone avrebbe potuto scambiarlo per un pesce d'aprile.

Chemistry and Materials Research è una delle riviste scientifiche edite dall'IISTE, una rivista di discreto impact factor (5,51). Una rivista su cui è stato appena pubblicato un corposo articolo del gruppo di ricercatori guidato da Francesco Celani; per una bella coincidenza - o meglio sincronicità junghiana - è successo proprio il giorno di Pasqua, ovvero della Resurrezione... quella che sta coinvolgendo chi ha seguito - per amore della scienza - le orme di Fleischmann e Pons nonostante l'indifferenza e la derisione dell'establishment accademico.

Si tratta di un articolo redatto ad Aprile 2012, sulla tecnica di preparazione dei fili costantana, tecnica che nel frattempo ha subito una non indifferente evoluzione. Del resto si sa, quando un paper viene sottoposto alla trafila della peer review i tempi di uscita si allungano...

Abstract
This study shows in detail how even a low cost material, like commercial Cu-Ni-Mn alloy (named Konstantan or ISOTAN 44), as far its surface is properly modified from the point of view of dimensionality, can be used as material able to produce anomalous heat effects due to close interaction with Hydrogen (or Deuterium, but at lower intensity) at high temperature.

Già che ci sono vi lascio, sempre firmato dal gruppo di Celani (con qualche new entry), anche l'abstract, di un lavoro - più attuale - che verrà invece presentato integralmente all'ICCF-18:

Abstract

In the framework of those studies aimed to analyze anomalous effects (thermal and/or nuclear) due to the interaction among some specific materials (pure and/or alloys) and H₂ (or D₂), we focused, since 2011, on a specific alloy called Constantan (Cu₅₅-Ni₄₄-Mn₁). We selected such material using our own considerations and intuitions and because, according to a scientific paper [1], it has the largest energy value for dissociation of H₂ to 2H, i.e. about 3eV. Among others B. Ahern suggested that Ni-Cu-H can be used for heat generation. We improved the preparation procedure of such wire from simple thermal treatments (up to May 2012 [2]) to more sophisticated ones, with more tight control of the multilayered (400-700) surface structures. Some of the results were presented at ICCF17, Aug. 2012 [3]. After [3], several groups asked to make their own experiments using such kind of wires (Φ=200µm, l=100cm) to cross-check (and possibly improve) our results. Some of such Researchers (group of M. Fleischmann Memorial Project; U. Mastromatteo) made public their (positive) results since Dec. 14, 2012 at Ministry of Aeronautics in Rome, Italy. In short, using an (home-made) apparatus integrated with an acquisition system (type PXi) by National Instruments, we made, since September 2012, not mentioning qualitative reconfirmation of previous results, further and unexpected progress and discoveries:

1. We developed a new kind of procedure of measurement (about anomalous excess heat) under dynamic vacuum, to avoid the effect of different thermal conductivity, inside the gas cell, due to type of gas and pressure variation: the wire didn’t lose, macroscopically, H even at T=600°C.
2. We developed a new, very simple, type of surface coating (2 layers) that is nano-diamandoids like;
3. We observed, at least 2 times, the phenomenon of water splitting due to catalytic effect of surface treated Constantan. Such phenomenon is larger in comparison with what expected just by thermal splitting (wires temperature of about 300-500°C);
4. We observed a very large variation (about a factor 100) of Resistive Thermal Coefficient (RTC) of the wire used (400 layers) as the amount of H (related to the macroscopic value of resistive ratio R/Ro, normalize to empty wire Ro) increased. As example, with ”treated” virgin wire (w/o H₂) the RTC was about 5*10^-6 and increased to 6*10^-4 when the R/Ro reduced to 0.68; temperature range 20-300°C. The RTC is larger with D in respect to H. Experiments are in progress also at 77K.
5. Overall results are affected by previous operating conditions
