It has been reported that anomalous excess heat was observed using some metal composite absorbed hydrogen gas [1, 2]. Nano-sized metal multilayer composites on Ni substrate and hydrogen gas induced heat bursts and excess energy generation. However, the reaction mechanism and the conditions to cause these phenomena to have not been cleared. To obtain the key factors to understand what is happening in a nano-sized metal multilayer composite, we have been studying on reaction products using various analysis methods.
Surface of the multilayer thin films on a Ni substrate, prepared by Ar ion beam sputtering method, was used as the nano-sized metal composite. Multilayer samples were absorbed hydrogen gas and conducted to heat up to 500~900°C. To understand about the surface states, depth profiles and mass spectra for before and after experiment samples, we performed to analyze each sample using scanning electron microscope (SEM)/ energy dispersive X-ray spectroscopy (EDX), transmission electron microscope (TEM) and time of flight secondary ion mass spectrometry (TOF-SIMS).
As a result, the surface states of the samples which were subjected to heating up to 500~900°C after hydrogen gas absorption were different from reference samples. The characteristic elements including C, O, Na, Mg, Al, Si, Zr, K, Ni and Cu were detected by SEM-EDX in a nano-sized metal multilayer composite sample that generated the anomalous heat. The sample was fabricated with Cu and Ni layers in 96 nm thickness. Also, the depth image of the sample with 96 nm layers of Cu and Ni indicated non uniform distribution for each element. We found that it did not remain the layer composition by the depth profile using TOF-SIMS.
On the other hand, nano-sized metal multilayer composites formed by Cu and Ni with CaO or Y2O3, which showed 103 ~ 104 eV order excess energies per hydrogen, indicated difference surface state. However, the behavior of Ca or Y derived from CaO or Y2O3 containing Cu and Ni multilayer by the depth profile using TOF-SIMS was similarly near the surface; they did not depend on each element. We guessed that any elements diffused through the similar process and interaction. To understand the relationships among anomalous heat generation, reaction products and elemental distribution, we will continue to examine using various analysis methods.

Since 2015, Tohoku University has established a division of Condensed Matter Nuclear Reaction, and has been conducting research on anomalous heat generation phenomena using hydrogen and nano-sized metal composite. As a result, we have succeeded in observing the anomalous heat generation phenomena that cannot be explained by the chemical reaction-. At the same time, it should be noted in the experimental results that no γ-ray transitions from reaction-generated nuclei, which are supposed to be caused by the nuclear reaction, are observed at all.
However, there has been little search for electromagnetic radiation in lower energy than 50 keV. If the novel nuclear reaction occurs, a region with very high energy density would be formed locally in the condensed matter. Then, expected are emissions of low-energy photons associated with energy dissipation from the local high-energy-density spot. The unexplored low-energy region is very wide; from the X-ray region, where electron bremsstrahlung and characteristic X-rays of the host metal can be expected, to the infrared region where thermally radiated photons are expected mainly. Of particular interest is the spectrum of the visible light, because it may indicate thermal radiation from a local high-temperature region (hot spot).
In previous experiments, it was impossible to observe such low energy photons, since the heat-generating nano-sized metal composite is shielded by the stainless-steel container; even if the low energy photons are emitted, we cannot observe them. Therefore, we made a vacuum chamber that enables photon observation from the infrared region to the X-ray region, and started measuring photons accompanying the anomalous heat generation.
Our experimental process is as follows. First, we use samples in which Ni / Cu nano multilayer films are formed on Ni substrates by sputtering. These are fixed on both sides of a ceramic heater installed in the vacuum chamber. After baking, we made hydrogen absorbed (200-300Pa, 250℃, 15 hours) to the sample. After that, we heated the samples up while evacuating the chamber, and induced anomalous heat generation. We measured the sample temperature with a thermocouple installed inside the ceramic heater and evaluated the heat generation by comparing it with temperature of a reference sample (Ni substrate without a nanostructure).
The following two instruments were installed for the measurement of low-energy photons. (1) For low-energy soft-X-rays (1keV-100keV), we made it possible to detect with an SDD detector (XR-100SDD; AMPTEK Inc.) through a Be window installed in the chamber. (2)For visible light measurement, a spectroscope using amp array CMOS image sensor(C12666MA; Hamamatsu Photonics K.K.) was installed, and the visible light transmittedthrough the viewport was guided to the spectroscope using a fiber so that the spectrum (340-780nm) could be measured.
Details of the experiments and results will be reported.

Latest results on anomalous heat effect (AHE) by interaction of binary nano-composite metal powders and H (or D) gas, after the NEDO-MHE project (2015-2017), were reported by our ICCF22 presentation and paper.
Re-calcination of PNZ (Pd1Ni10/zirconia) and CNZ (Cu1Ni7/zirconia) powders was found to be effective for the enhancement of weeks-sustaining excess thermal power Wex. We report further results by additional calcinations and baking treatments in this paper. In Table -1, summary results for PNZ10, PNZ10r and PNZ10rr samples with D (deuterium)-gas are given. Detail of data will be shown in the meeting. Study by CNZ7, CNZ7r and CNZ7rr samples with H (light hydrogen)-gas will also be reported.

Kitamura et al.and Iwamura et al.reported they observed about several tens-watt anomalous heat generation and sudden rise of pressure and gas temperature using their original evaluation system when hydrogen isotope gas was introduced into the nano-metals [1, 2]. To apply this technologyto industrial products such as automotive heaters, further output power enhancement is required. However, there is no distinct strategy for higher output since relation of output to experimental parameters is unclear. The conventional evaluation system issuitable for long time and large scale experiment (several months and a few hundred-gram of the material) and it is hard to change experimental conditions frequently.
In this work, we investigated the relation of output to temperature, pressure,interval of data acquisition and gas atmosphere using partially oxidized Pd-Ni-Zr alloys (PNZ) and non-oxidized NiyZrxalloys with a differential scanning calorimeter (DSC) without exposure to air. In addition, sample structure and hydrogen storage property were analyzed using an in-situ X-ray diffraction (XRD) and pressure-composition isotherm measurement.
The DSC experiments revealed irregular oscillation pattern associated with heat generation was observed reproducibly using not only PNZ but also NiyZrxalloys. Additionally, we found the width of oscillation was increased as temperature increase or hydrogen pressure decrease. When we changed the gas atmosphere from hydrogen to inactive gas, the oscillation was terminated immediately. This indicates hydrogen in thegas phase is necessary to occur the oscillation.The change of sample structure and P-C-T isotherm suggest the oscillation relates a phase transition of metal hydrides.
