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 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. The interest in Ni comes in part b...
We presents some improvements on the reactor presented at ICCF14 (Washington D.C. August 2008): use of long-thin Pd wires with nano-coated surfaces by multi-layers of several elements, loading with D2 at pressure 500°C; Stainless Steel (SS) reactor wall temperature
At the National Institute of Nuclear Physics (Frascati National Laboratories), we focused, for over three years on methods to generate anomalous excess heat at temperatures (T) well over that allowed by unpressurised traditional electrolytic environments (by light or heavy water; T < 100°C). Our goal was to develop a device able to generate heat at...
There were improved measurements on our reactor presented at ICCF14 (2008): longthin Pd wires with surfaces nano-coated by multi-layers of several elements, D2 at P<10bar; wires temp. <500°C; SS reactor wall temperature <100°C; longitudinal current density up to 45 kA/cm2 (voltage drop up to 70V); transversal electric field up to 700V/cm. Previous...
A high peak current generator (up to 100 A) of short pulse width (about 1 μS) was used to electrolyse D2O-LiOD solution using a Pd sheet cathode and a Pt wire net anode. The pulse (up to 50 kW) can be repeated up to 20 KHz. High D/Pd loading values (up to about 1:1) have been reached with the cold-worked Pd sheets used. A very hard cathode (about 3...
After Takahashi reported large excess heat with pulsed electrolysis, we built a gas-closed flow calorimeter to perform pulsed current electrolysis. Blank tests using Au plate cathodes were carried out to characterize the system. Four cold-worked Pd sheets were tested, and two of them produced 7.5% and 6% mean excess heat for many weeks. The others...

... 2-(3))], the higher the sample temperature the more the nuclear reactions, is clearly shown in the excess heat vs. heater temperature relation as seen in Fig. 4.2 and as shown more clearly in Fig. 4.4 [Iwamura 2020b (Fig. 6)]. [Celani 2012[Celani -2020b The extensive investigation of the constantan wire coated by sub-micrometric surface layer has been performed by Celani et al. [Celani 2012[Celani -2020b. We will give rather minute introduction to their work in another paper presented in this Conference [Kozima 2021a (Sec. ...

... • At the end of Fig. 12 the unexpected beneficial effect of HPPP (High Peak Power Pulse) is shown. HPPP is discussed in our publications since 1993 experiments [20], [21], [22], [7]). The design of current pulser shares several features with the original one, nevertheless it has been improved in some specific respects. ...

... Since then, the gas-phase charging systems have been another important method to induce possible anomaly in heat generation. Successful replications using systems similar to the DS reactor with Pd-black have been reported by Kirkinski et al. [7], Biberian et al. [8] and Celani et al. [9]. On the other hand, Kidwell et al. [10], Hioki et al. [11] [12], and Dmitriyeva et al. [13] have also developed independently gas absorption systems with precise calorimetry equipments for samples of Pd-loaded zeolites and/or alumina. ...
... Most of the results we report are obtained with Xe-D 2 mixture, mainly at a total pressure of 0.2 bar. Since 2010 [9], we added high Z noble gas (e.g. Ar) to reduce thermal conductivity of the reactors. ...

... 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]. ...

... 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 . ...

... During the experimental work with this technique, and after extensive discussions with A. Takahashi, we concluded that excess heat was related to mechanical hardening and to the type of surface texture present on the Pd plates. The experiments were performed in a "normal" (not underground) laboratory where we measured (9) by flow calorimetry excess heat up to 5-10% of applied power. We propose that "anomalous excess heat"is "triggered" by applying to the cell a low-high electrolysis current. ...
