    Verification of anomalous heat detected by differential scanning calorimetry from Palladium-Nickel-Zirconium alloy in hydrogen flow (2)

    It has been reported that anomalous heat different from hydrogen absorption heat is maintained for several weeks

    when hydrogen or deuterium gas is in contact with some metal alloys at a temperature of 200-300ºC.

    The total amount of the heat is so large that it cannot be explained by only chemical reaction [1].

    However, not only the mechanism of such anomalous heat generation but also the heat generation condition has not been revealed. To clarify the condition,

    it is important to evaluate the anomalous heat from a small amount of metal alloy sample that has a uniform temperature distribution.

    In this work, we examined the anomalous heat generation from a small amount of palladium-nickel-zirconium alloy (PNZ)

    by differential scanning calorimetry (DSC) under various conditions, which is aimed to clarify abnormality of the heat generation phenomenon.


    The DSC (Linseis PT1600H) measurements were conducted as follows.

    100 mg of PNZ sample (provided by Nissan Motor Corp.) was heated at 5 ºC/min to a predetermined temperature

    and then kept at the temperature for more than 4 h, during which the heat behavior of the sample was measured by DSC.

    In that manner, a sample was measured in both hydrogen and inert gas (helium, argon),

    and the difference of the heat flow between them was determined as the heat generation derived from hydrogen.


    First, nickel or zirconia sample which is a component of PNZ showed no difference in the heat flow between hydrogen and helium.

    On the other hand, in case of PNZ, the heat flow in hydrogen was significantly larger than that in helium, and the difference was maintained for more than 4 h.

    The heat flow difference is often due to changes in the specific heat of the sample, so we examined the heat flow difference when the temperature was changed periodically at 400±5 ºC. If the specific heat of the sample varies with hydrogen and helium, the heat flow difference must be constant even if the temperature changes periodically.

    However, it was observed that the heat flow difference changed periodically and that the change was out of phase with the temperature change.

    These results indicate that PNZ continuously emitted the heat derived from hydrogen at a constant temperature.

    Such heat generation was observed at above 250 °C and the maximum heat flow was obtained around 400 °C,

    while hydrogen absorption was observed below 250 °C.

    Despite the maximum exotherm at 400 °C, the hydrogen desorption from PNZ was observed at 400 °C by a temperature-programmed-reduction (TPR) method.

    These results clearly show that the heat generation from PNZ in hydrogen is not due to hydrogen absorption. Next we examined the phase transition in PNZ by powder X-ray diffraction (XRD) method, since metal alloys can undergo phase transitions at high temperatures, often generating heat.

    As a result, it was suggested that no phase transition occurred in PNZ below 450 ℃ in hydrogen and inert gas.

    Therefore, it was clarified that the continuous heat generation from PNZ in hydrogen above 250 °C was not caused by hydrogen absorption heat and phase transition heat.

  • Wyttenbach - it seems it is out of your control, to give up on ranting, hating and throwing mud and insults on hot fusion, ITER, CERN


    Its neither ranting nor out of control: The facts are well know since 1978 "unobtainium" the all mighty neutron curtain/blanket needed for ITER cannot be found at reasonable costs. Thus ITER is an ongoing act of criminal researchers looking for a fun job nothing more.


    CERN invented particles to get more funding instead of correctly reporting resonances only.


    You can say that's clever marketing as there are plenty of useful secondary products developed. Also technology makes big steps forward.


    The problem is that these people block more than half of the world wide free/open research money that could be used for really important stuff like battery development, better insulation, solar cells, LENR etc.

  • You will insist on F&P being wrong ad nauseam, fair enough, let’s entertain that position for the sake of argument.


    Sorry, for the nausea. Anyway, it's only just one year that I am reminding L-F readers that F&P were wrong. They were the founders of CF, so they are much more related to the field than Edison or the Wright brothers, who have been cited for almost 30 years to support the idea that F&P were right.


    Quote

    But then Jones et al were wrong, too, and their April 27th 1989 article published in Nature, should be withdrawn?


    I don't care about Jones. He is not considered the founder of CF. So, I don't know if his article should be withdrawn by Nature. I can only tell you that, at the end of a very interesting thesis on the "The Rhetoric of Science: A Case Study of the Cold Fusion Controversy" discussed in 1992, D.L.Hatfield concluded that:


    From https://pdfs.semanticscholar.o…d85cc9587bbba3de94a3f.pdf

    Starting from page 138 of the thesis (emphases added):


    However, the theme of "improbability" is evoked twice by Maddox. Earlier in this same editorial, he admits that "the Fleischmann and Pons experiments raise bigger questions, if only because the scale of the phenomenon they report is so much greater." Here, Maddox argues that "given its improbability," the claim is most likely false because it claims too much. If Maddox is reflecting a theme at large in the general scientific community, one may term it the topos of plausibility, in which case the lay connotations of reasonable— plausible, likely, moderate, and sensible— would translate into scientific reasonableness. If such is the case, it explains one of the reasons why Jones' claims, in which the fusion rates are much lower than Fleischmann and Pons, are the more well accepted and less criticized. Jones' claims would be considered the more scientifically reasonable because they suggest less disruption to accepted knowledge concerning nuclear fusion than Fleischmann and Pons's claims, which require proposing a new type of nuclear fusion.


    What I can say with certainty is that the F&P article "Calorimetry of the Pd-D20 system: from simplicity via complications to simplicity" published in 1993 (1) should be withdrawn by Physics Letter A, with deep apologies to its readers.

    I'm sure that we are all touched to know that you consider yourself- at a distance of many thousands of miles and 30 years to be a better judge of those experiments than the two world-class scientists who performed them. However, I am never sure if you consider them to be fraudulent or merely stupid. Which is it?

    Agree. Actually, the sentence of mines that you have quoted is not an absolute. It starts with an "I", so it implicitly express a personal opinion. I'm a man and I'm conscious of my limits. I made some errors (I hope I've recognized most of them) but I'm aware that I can commit others. Should I repeat it for every sentence I write?


    I urge readers to check every single statements I write by looking at the links I provide or at any other source they have.

    I consider them just wrong. As already explained at length in these threads:

  • Hi LeBob,

    thank you for your reply. You raised a good point.


    I don't know exactly what you mean by "plasma based systems with self organization or a more explosive release", so let me assume that they have something to do with the Satoh et al. article mentioned by RobertBryant as an example of "potencial theories [that] have changed and increased in detail since" F&P experiments.


    This Satoh article mentions a single reference: "Excess heat evolution from nanocomposite samples under exposure to hydrogen isotope gases" by Kitamura et al. (including Kishida, one of the authors of the Satoh article), published in the International Journal of Hydrogen Energy in 2018 (1).


    Well, the few lines of the first chapter (Introduction) appearing on the first page mention F&P, Celani and Rossi. By coincidence, I have examined papers and claims related to the CF/LENR activity of all of them and this is enough for me to conclude that there is no reason to turn the page to start reading the second page. IMO, Kitamura and, consequently, Satoh articles can be dismissed without looking at their contents, because their premises are wrong.


    This is the problem. Almost every papers on LENR are introduced by a chain of references which start with F&P, so that they explicitly state, or imply, that their findings were real but unfairly dismissed by mainstream science. However, IMO, F&P were wrong in such blatant and obvious way that researchers who are unable to recognize and admit these errors are also prone to commit the same mistakes.


    IMO, in order to possibly regain some credibility, the category should first solve this big problems with its past, recognizing that F&P were wrong. The present still going 30th year from the F&P announcement is a good and unique occasion to put a big dot and turn the page.

    (1) Observed absorption and heat evolution at RT were not anomalously large, and could be of explainable levels by some chemical processes.

    (2) At ET of 200 ~ 300 °C, most samples with binary metal nanocomposites produced excess power of 3 ~ 24W sustainably lasting for up to several weeks.

    (3) The excess power was observed not only in the D-Pd⋅Ni system but also in the H-Pd⋅Ni system and H-Cu⋅Ni system.

    (4) On the other hand, single-element nanoparticle samples produced no excess heat at ET.

    (5) PNZ6 and PNZ6r samples with Pd/Ni=1/10 generated much higher excess power than other PNZ samples with Pd/Ni=1/7. The Pd/Ni ratio is one of the keys to increase the excess power.

    (6) The maximum phase-averaged excess heat energy, ηav,i, exceeded 270 keV/D (26 GJ/mol-D), and the integrated excess energy Ea reached 1 keV/Pd⋅Ni (100 MJ/mol-M) and Eex = 90 MJ/mol-H.

    (7) It is impossible to attribute the excess energy to any chemical reaction; it is possibly due to radiation-free nuclear process.

    (8) The anomalous heat effect was observed with very small amount of D(H) transfer in both direction of net absorption and net desorption. It is conceived that this might be a hint for AHE generation sites and some nuclear mechanism in the binary metal nanocomposite samples and may match with the models by Takahashi TSC theories.

    Ah, OK. Now I understand what you meant.


    I didn't examined any of these apparatuses and related experiments, but it seems to me that they are very far from F&P cells or any evolution close to their approach. Have any of the proponents of these systems claimed that their apparatuses are an evolution of F&P cells? In my previous post (*), I was referring to the CF/LENR phenomena as summarized at the beginning of the linked video, that is the "strangeness's that sometimes happen when H or D is put into special metals" (my translation).


    In any case, I confess, I'm also very skeptical of the ability of the plasma based systems you mentioned to generate any measurable amounts of nuclear phenomena, but this opinion is not based on a direct examination of the respective results. So this is just a personal opinion, not my convincement of non-existence, as it is for the results claimed by F&P, Celani, Rossi and Mizuno.


    Btw, may I ask you, what do you think about the "1992 boil-off experiment" of F&P? Are their conclusions correct?

    1. INTRODUCTION

    There have been continuing interests in research on various effects by hydrogen-gas charging of transition metal compounds, for application to energy storage devices and catalyser materials, and so on. The interest increased further, when palladium was used as a cathode of heavy water electrolysis to charge with hydrogen isotopes and induce extraordinarily large energy, the so-called cold fusion, claimed by Fleischmann-Pons in 1989. Since then a number of experiments have been performed to reproduce the phenomenon, namely the anomalous heat effect (AHE), with use of palladium. However, most of them have been unsuccessful in replication. Only a few experiments claimed positive results using the electrolysis method or the gas-phase charging method.

    Recently, nickel-based nanocomposite samples have come to gather attention owing to higher availability of nickel than palladium. A Ni⋅Cu⋅Mn alloy thin wire, for example, has been examined extensively by Celani et al. [1]. In addition, a number of entrepreneurs are publicizing their own “products” of nanofabricated samples on web sites with undisclosed details, and therefore with little scientific corroboration [e.g., 2, 3]. Among them, replication experiments of the Rossi-type reactors have been performed by several researchers [4 - 7], which seemingly appears to show unignorable ...


    My reading stops here. I'm sorry, but I don't even feel the curiosity to give a look at the beginning of the next page, to see what Kitamura et al. consider unignorable facts.
