10.Differential scanning calorimetry verification of abnormal heat of palladium-nickel-zirconium alloy in hydrogen flow

Kyushu University Yukiko Sato

In this paper, differential scanning calorimetry (DSC) is used to study the abnormal heat generation of a small amount of palladium-nickel-zirconium alloy (PNZ) under different conditions in order to clarify its abnormal heat generation.

This heat generation was observed above 250 ° C, and the maximum heat flux was obtained near 400 ° C, while the hydrogen absorption was observed at 250 ° C. Although there was a maximum exotherm at 400 ° C, it was reduced by program temperature rise (TPR Method) Hydrogen desorption of PNZ was observed at 400 ° C. These results clearly show that the heat generated by PNZ in hydrogen is not caused by hydrogen absorption. Next, we studied the phase transition of PNZ using powder X-ray diffraction (XRD), because metal alloys can undergo phase transitions at high temperatures and usually generate heat. The results show that PNZ does not undergo a phase change in hydrogen and inert gases below 450 ° C. Therefore, it is clarified that the continuous heating of PNZ in hydrogen above 250 ° C is not caused by the heat of hydrogen absorption and phase change.

11 Calibration of Sendai mass flow calorimeter and thermal measurement of recovered samples

Tohoku University Takeno Masahiko

A mass flow calorimeter [1] developed by Kobe University Technova enables accurate heat flow measurement at a temperature of about 300 ° C in a composite metal nanoparticle hydrogen (deuterium) gas system using an oil coolant. In the NEDO project, we have made basically the same calorimeter, conducted many experiments using the same sample as Kobe Technova, and proved the reproducibility of the phenomenon of abnormal waste heat generation.

We have now investigated further improved thermal measurements to find X-ray radiation and reactive residual gases associated with excess heat generation. The following actions have been performed. (1) Calibrate the calorimeter by adding / changing measurement parameters without changing the current state, and (2) Calibrate the calorimeter by directly receiving heat radiation from the reaction chamber and the measured amount to date .

12, Desorption of deuterium on surface-coated palladium foil with fine structure interface

Iwate University Endo

Deuterium desorption experiments were performed on samples prepared by depositing different metal films on palladium foils, and the temperature and deuterium diffusion behavior of the samples were studied. For Pd-Ni or Pd-Ni-Zr samples with fine interfaces, we observed a special temperature change [3, 4]. The results indicate that the characteristic diffusion of deuterium may be caused by specific conditions.

Although no significant excess heat was observed in the experiments, we can systematically study the deuterium diffusion behavior of different types of samples to find the trigger conditions that induce excess heat.

13. Development of a small cavity reaction system for basic experiments on abnormal thermal effects

Waseda University

In this work, we developed a small chamber reaction system and performed basic experiments to verify the occurrence of anomalous thermal effects.

14.Laser irradiation D-load Pd

Kyoto University

The experimental device is a gas-phase clustering reactor system made of stainless steel, including a deuterium loading chamber, an electron beam deposition chamber, and a reaction analysis chamber. The facility is equipped with a high-resolution compact amu quadrupole mass spectrometer, two gas-proportioned neutron detectors, a Geiger Muller detector for alpha, beta, and gamma rays, and two liquid scintillators. In this work, we installed a variety of lasers in the gas phase D-Pd reaction system to irradiate Pd samples as an energy stimulation support, potentially enhancing the local field of the plasma. The lasers are 405nm and 594nm continuous wave semiconductor lasers, respectively, with powers of 50 and 30mw, and the peak power of 1064nm pulsed YAG lasers is 10mw.

The preliminary result is that we simultaneously observed a sudden overshoot of the temperature and a neutron signal. It is worth noting that we observed a large number of clear signals generated by 4He from the Pd sample by in situ mass spectrometry, that is, the shoulder on the D2 peak and a gas species with a mass of 3. We have also observed a sudden outbreak of these gaseous species from palladium samples. Our results may indicate that there is some abnormal nuclear-related response in the D-Pd system. The conference will detail experimental conditions and further results.

15. Abnormal heat of new binary metal system under hydrogen flow (2 )

Kyushu University

In the experiment, two commercially available metal powders were physically mixed, and then DSC was set. In differential scanning calorimetry (DSC), a mixed sample is preheated in a helium stream to a temperature above the melting point of one of the mixed metals and cooled to room temperature. During the pretreatment process, some metal alloys were formed in the sample. For the measurement, the sample was heated to a predetermined temperature (300 to 800 ° C) at a temperature of 5 ° C / min, and kept at that temperature for a constant 2 hours, during which the thermal behavior of the sample was measured by DSC. The mixed sample is measured in hydrogen and helium. The difference in heat flow between the two is considered to be exothermic / endothermic by hydrogen.

It was found that at 500-800 ℃, some binary metal systems generated abnormal heat for the first time. The exothermic heat flux of the samples of the Al-Ni binary system was greater than 300 mw / g, which was the same as that of the Pd-Ni-Zr samples with the same DSC device. Compared with 20mw / g, the exothermic heat flow is much larger. Similarly, the binary systems of Al-Ti (40 mW / g at 700 ° C) and Al-C a (90 mW / g at 400 ° C) also exhibit large abnormal heat at high temperatures. Repeated evaluation of these samples showed that the abnormal fever was highly reproducible.

The above is the outline of fifteen papers.

Professor Mizuno Tadohiko did not participate in the research work of the four companies, Clean Planet, Kobe Technology Rising Star Company, Nissan Motor Company, Osan Electric Power Company, eight universities participated in the research work, Tohoku University, Osaka University, Kobe University, Kyushu University, University of Tokyo, Iwate University, Waseda University, Kyoto University Research on Cold Fusion in Japan There are many companies and universities involved in the research. The team is constantly growing and should be the world leader.

Of the fifteen papers, thirteen are experimental papers and two are theoretical papers. Of the thirteen experimental papers, nine are studies on excess heat, two are on nuclear products, and two are on fuel morphology. The research direction focuses on experimental research and is very pragmatic

Was I right in feeling enthusiastic about JCF20 ?

The abstract don't show much results, but the approaches looks very good for me ?

as Ahlfors cites, observing the produced light is among great ideas...

The analysis of the LENR instabilities by Nissan team looks strange I imagine, for me it is great too, like the work of Kozima, because it may give hint not on details, but on the mathematical nature of the equations of the phenomenon...

Trying to replicate LENR should be great, but it seems to have produced no recognition...

My feeling is that today people don't believe you if you don't have a theory, and instruments, observations , is what can give us hint on the theory...

The work by Holmlid, the study of Brillouin electrodes by THz spectroscopy (Anis Rahman&al), are also great directions...

Am I rational in feeling so?
