This paper is mostly based on our presentation given at the 23rd International Conference on Condensed Matter Nuclear Science (ICCF23) held at Xiamen University (XMU)-PRC on June 9-11, 2021, but largely enriched to satisfy the requests of the referees. Upon the suggestion of the Conference Organizers, we added a detailed explanation of our procedur...
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...
Following the efforts to find simple procedures to activate the specific material we developed (since 2011; based on surface-modified Constantan in the shape of long and thin wires, Joule heating), able to produce measurable values of AHE we reproduced them. Made new specific tests to investigate also isotopic effects. Moreover, according to our in...
The presentation is a review of the last results discussed in several recent conferences on LENR, aimed to give an overwiew of the state of the art of the experimentation to a diverse and non-specialistic audience interested in the energy production from Hydrogen. Some preliminary results from our entourage are showed as well.
One more 3-days Workshop, series ANV (Assisi Nel Vento), of Multidisciplinary Science (mainly: Energy, Medicine, Geology) was held in Assisi-Italy; part of the Workshop had even arguments related to Philosophy/History/Art/Religion. The reported event was the 8th edition (December 2021). One of the characteristics of such Workshop is that the time s...

[Enriched version of the original presentation]
This short presentation introduces an experimental design for the enhancement of the anomalous thermal phenomena (AHE) observed since 2011 in Constantan3 wires exposed to a deuterium or hydrogen atmosphere, and heated by direct current. In fact, the occurrence of AHE requires specific conditions such...

This paper presents a summary and some deeper details about the experiments presented at the 22nd International Conference on Condensed Matter Nuclear Science (ICCF22). It reports on the experimental study of LENR phenomena in Constantan (Cu55 Ni44 Mn1) from its inception in 2011 to the most recent experiments. Using an empirical approach we identi...
Anomalous Heat Effects (AHE) have been observed in wires of Cu55Ni44Mn1 (Constantan) exposed to H2 and D2 in multiple experiments during the last eight years. Improvements in the magnitude and reproducibility of AHE, and improvements in wire preparation and reactor design were reported by the authors in the present and previous papers. The oxidatio...
Our group has been studying LENR phenomena in Constantan (Cu55 Ni44 Mn1) since 2011. In fact, this alloy captured our attention since it promotes efficiently the dissociation of molecular Deuterium (D2) or Hydrogen (H2) to the atomic state, followed by a remarkable absorption capability. Under certain conditions, this absorption is associated with...
In 2011, we introduced the use of constantan alloy in LENR, in the form of long and thin wires as a hydrogen dissociation promoter. We disclosed for the first time the reason for the choice of such material at IWAHLM-12 Workshop (2017), hypothesizing it was the initiator of the reaction in Andrea Rossi's experiment. We developed a specific treatmen...

Will be shown main steps aimed to identify the key parameters needed to get AHE (Anomalous Heat Effects) at high temperatures (>300°C) during the absorption/storage
and flux of Deuterium gas in a specific alloy ( Constantan: Cu55_Ni44_Mn1), thin and long wire shaped, with surface at sub-micrometric dimensionality. Constantan is also coated by Low...
An unconventional research program has been initiated in 2011 aiming to increase both the magnitude and reproducibility of Anomalous Heat Effects (AHE) in the field of Low Energy Nuclear Reactions (LENR). The program focused on the study of Constantan, an alloy of Nickel and Copper (Cu55Ni44Mn1), instead of metals such as Pd, Ti, Ni that have been...
] Since 2011, at INFN-LNF, we investigated the behavior of Constantan (Cst) alloy (Cu 55 Ni 44 Mn 1 ; ISOTAN44) as concerns Hydrogen and/or Deuterium (H 2 /D 2) absorption and generation of Anomalous Heat Excess (AHE) at High Temperatures (HT, i.e.>>200 °C). To further improve the intrinsic, excellent, catalytic proprieties of Cst toward H 2 2H di...

Since 2011, we introduced into the LENR Research field, the use of a Constantan alloy to absorb and adsorb proper amounts of H2 or D2 (concentrated and/or mixed with noble gases of low thermal conductivity) and to generate thermal anomalies even at low temperatures (>200°C wire temperature). Based on this idea, we developed a reactor with a core of...

... The surface is roughened 7 and coated with Low Work-Function (LWF) oxides; • Presence of a flux of atomic or ionised, deuterium or protium. 5 It is unluckily Constantan may ever be subject to a monopoly, constrained, or limited supply. Similar alloys for instance are commonly used in the minting of coins. ...
... • The Richardson effect [6] occurs at high temperatures 20 and allows a continuous flow of electrons from the surface of a material where they just "boil-off". In our case, the emission of electrons is increased at relatively low temperature thanks to a coating of low work-function oxides 21,22 . The dependence of current density on temperature and work-function of material surface is shown in Fig. 5. ...

... Our group has studied Anomalous Heat Effects (AHE) in nickel-copper alloys for several years [1][2][3][4][5][6][7][8][9][10]. Apart from some initial speculation [5] one of the motivations for the choice of these materials came from the work of Romanowski [11] who showed their remarkable capability at promoting the dissociation of molecular hydrogen (H 2 ). ...
... Therefore, aggregates of neutral charged ultra-dense deuterium would be, according to this hypothesis, the probable responsible for the transmutation of Cs into Pr and Sr into Mo. It is possible that strontium oxide, with its very low work function, substitutes the calcium oxide role in Celani's experiments [24]. By using again the Holmlid notation "D(0)" to indicate "atoms" of ultra-dense deuterium, the hypothesized many-body reactions in Iwamura experiments [25] would be very simple: In the above equations the symbols 4D(0) and 6D(0) represent picometric, coherent chains of ultra-dense deuterium particles. ...
... This structure may be created starting from atomic hydrogen or Rydberg State Hydrogen only in specific environments, as materials with high free electron density and with lattice constants and energy levels allowing a resonant absorption of 3.7 keV photons. A high electron density can be obtained in "swimming electron layers" formed when a metal is heated in contact with materials, such as SrO, with low work functions [34,35]. ...
