Profil supprimé | Quelles news depuis le WE dernier...??? Commençons par la dernière revue électronique (bi ou tri-annuelle) de la Société Internationale de la Science Nucléaire dans la Matière Condensée, créée en 2004 suite au besoin des chercheurs du domaine de la fusion froide d'avoir une organisation qui les représente. Elle est basée au Royaume Uni, et l'une des activités importantes de cette organisation est la publication du « Journal of Condensed Matter Nuclear Science ». C'est la seule revue dédié exclusivement à la fusion froide. Elle est publié gratuitement, de manière électronique sur le site de l'association.
Les revues sont composées de rapports de chercheurs, évalués par des chercheurs du domaine, une sorte de peer review en interne, les revues scientifiques boycottant le sujet en ne lui permettant aucune évaluation (et donc aucune publication). Citation :

Abstract : Spin-polarized Density Functional Theory (DFT) calculations have been performed to model the lattice structures for the Transition Metal Group, Columns I and II, and a number of sp elements in the Periodic Table. Our results suggest that most of the transition metals can exhibit ferromagnetic ordering if the lattice is placed in sufficiently high tensile stress. These results are applied to the study of some layered structures employed by a number of Low Energy Nuclear Reaction (LENR) research teams and may help to explain some of the anomalous results and the difficulty in reproduction of those results.
Nuclear Exothermic Reactions in Lattices: A Theoretical Study of D–D Reaction
Fulvio Frisone - Department of Physics, University of Catania, Italy
Abstract : In this work we try to explain the deuteron–deuteron reactions within palladium lattice by means of the coherence theory of nuclear and condensed matter. The coherence model of condensed matter affirms that within a deuteron-loaded palladium lattice there are three different plasmas: electrons, ions and deuterons plasma. Then, according to the loading percentage x = D/Pd, the ions deuterium can take place on the octahedrical sites or in the tetrahedral in the (1,0,0)-plane. In the coherence theory it is called β- plasma the deuterons plasma in the octahedral site and γ-plasma which in tetrahedral. We propose a general model of effective local time-dependent deuteron–deuteron potential, that takes into account the electrons and ions plasma oscillations. The main features of this potential are extracted by means of many-body theory considering the interaction deuteron–phonon–deuteron. In fact the phonon exchange produces a attractive component between two deuteron within the D2 molecular. This attractive force is able to reduce the inter-nuclear distance from about 0.7 to 0.16 Å. It means that the lattice strongly modifies the nuclear environment with respect to free space. In this way according to deuterons energy, loading percentage and plasma frequency we are able to predict

Empirical Models for Octahedral and Tetrahedral Occupation in PdH and in PdD at High Loading
Peter L. Hagelstein - Massachusetts Institute of Technology, Cambridge, MA 02139, USA
Abstract : High D/Pd loading is known to be a requirement for producing excess heat in the Fleischmann–Pons experiment, and much work has in recent years been focused on electrochemical protocols and cathode processing in order to achieve D/Pd loadings approaching unity routinely. However, we know very little about PdD at a loading near unity, and almost nothing about what happens when the loading exceeds unity. It may be that when the octahedral sites are fully occupied, additional interstitial deuterium atoms occupy tetrahedral sites, a proposal which at this point has little experimental support. It is nevertheless possible to construct an empirical model for this scenario, and to make use of available experimental data to fit the associated model parameters. We worked with empirical models for both PdD and PdH that assume an O-site energy quadratic in loading, and an O-site to T-site excitation which is either constant in loading, or else taken as an empirical function fit to estimates inferred from the analysis of experimental data. There are two empirical models, each with four or more free parameters; and insufficient experimental data from which to choose each parameter or function independently. We add supplementary constraints that presume the models for PdH and PdD must be very similar, which reduces the number of degrees of freedom within the models. This allows data from PdH to be used to construct a model for PdD, and vice versa. The models which result are interesting; they suggest these complicated systems might be understood based on a simple underlying picture; they indicate that there is more T-site occupation than has been appreciated previously in the literature; they indicate that the resistance ratio calibrations for PdH and PdD are inconsistent; and finally, measurements of the chemical potential at high loading have the potential to provide information about the O-site to T-site excitation energy.
O-site and T-site Occupation of α-phase PdHx and PdDx
Peter L. Hagelstein - Massachusetts Institute of Technology, Cambridge, MA 02139, USA
Abstract : An important study of the solubility of hydrogen in α-phase PdHx and deuterium in α-phase PdDx over a wide temperature rangen was published by Clewley et al. (J. Chem. Soc., Faraday Trans. 1: Phy. Chem. Condensed Phases 69 (1973) 449–458). An analysis of the data based on an empirical solubility model based on O-site occupation allows for an understanding of the data at low temperature, but probably is not a good starting place for understanding the solubility at high temperature. We have applied a recently developed empirical model for both O-site and T-site occupation to this data set, and find good agreement between data and a basic version of the model which assumes that the O-site and T-site partition functions are taken to be harmonic oscillator partition functions. Even better agreement is obtained when a more realistic O-site partition function is used. A range of optimum models with different assumptions about the T-site partition function is considered, and it is found to be possible to select one that matches the T-site occupation at zero loading inferred from neutron diffraction measurements of Pitt and Gray (Europhys. Let. 64 (2003) 344). The O-site to T-site excitation energy is assumed independent of temperature in these models, and we obtain specific model values of 105.3 meV for α-phase PdDx and 106.5 meV for α-phase PdHx .

Abstract : This paper discusses the mechanism of cold fusion with deuterium and other elements implanted in the potential sites of conductive crystals. Cold fusion in metals becomes possible due to the fact that the implantation of atoms in a crystal guides them to their p excitation levels, which are determined primarily by the positioning of free conduction electrons in a zone of potential sites. The excitation energy of the p-states is about 10–14 eV. The excited atoms’ orientation in the crystal is not random but dictated by the crystal lattice’s electrostatic potentials. Calculations show that the transparency of the Coulomb potential barrier, for example, in the case of DD-fusion, increases by about 60 orders of magnitude if two deuterium atoms meet each other in the minima of the conductor’s potentials in the crisscross orientation. Most of the papers are devoted to the process of DD-fusion in the electrolytic saturation by deuterium in crystals, a process that is extensively studied in these experiments. This paper also briefly comments on other experimental results related to cold fusion.
Silica Favours Bacterial Growth Similar to Carbon

Abstract : Silicate solubilising bacteria were isolated from soil, river water, pond sediment and talc mineral. The isolates were characterised and found to belong to the genera Bacillus and Pseudomonas sp. Some of the isolates are also identified by 16S r RNA sequencing. Both Bacillus and Pseudomonas isolates solubilised magnesium trisilicate under in vitro conditions either in the presence or in the absence of glucose. Bacillus megaterium isolated from soil solubilised talc, feldspar and magnesium trisilicate by releasing silica in solution. This also exhibited growth exclusively on silicate in the absence of a carbon source and after removal CO2 in the head space of the flask containing medium. Bacillus mucilaginosus, a silicate solubilising species, exhibited growth on acid washed sand (pure quartz) and also in silicic acid in the absence of carbon source revealing the capability of the bacteria to utilise silica or silicate for its growth. The carbon analysis by SEM with EDAX revealed the presence of carbon in cells grown exclusively on silica suggesting the biological transmutation of silica to carbon. The ability of silicate solubilising bacteria to grow exclusively on silica or silicate in the absence of carbon reveals not only their ecological survival in a carbon-free environment in earth but also their likely survival in other celestial bodies.
Thermal Analysis of Explosions in an Open Palladium/Deuterium Electrolytic System

Abstract : An explosion occurred in an open Pd/D electrolytic system at a low current density of 62 mA cm−2. The average power was greater than 6.7 W (65 W cm−3 Pd or 430% of input power), and the incubation time was less than half an hour before the explosion. Thermal analysis indicates that the power of the explosion was 5.1–5.5 kW (or 50–53 kW cm−3 Pd), and the event developed in 2–17 s. It is concluded that this explosion was most probably caused by low energy nuclear reactions taking place in the Pd tube cathode rather than by chemical reactions.

Swedish Scientists Publish Paper Claiming “Ponderomotive Forces” Explain LENR
Posted on October 15, 2015
This new LENR theory, developed by Rickard Lundin and Hans Lidgren, is based around a the phenomenon known as ponderomotive force (‘a nonlinear force that a charged particle experiences in an inhomogeneous oscillating electromagnetic field’ — Wikipedia), and that neutrons are “shaken loose” from matter at resonant frequencies through an electromagnetic interaction, and when those neutrons are captured by another element, energy is released in large quantities.
Lundin and Lidgren have been in communication with Mats Lewan and have explained that the energy release and isotopic shifts described in the Lugano Report on Rossi’s E-Cat could be explained by ponderomotive force. Subsequently, they did an experiment of their own which verified their theory, but quickly stopped the experiment over concerns about neutron production. A new experiment is planned under carefully controlled conditions.
Input energy is needed to shake loose the neutrons, and Lundin and Lidgren have written a patent around their process. They told Mats Lewan:
“Our method is more precise, using the lowest possible amount of energy [through resonance] to shake loose the neutrons. Others like Rossi are creating turbulence through square waves [in the electrical current feeding the heat resistors controlling the reaction — square waves containing a large number of harmonics and thus many different frequencies], and they get a turbulent wave spectrum risking that some frequencies become a little too high.”
Lundin and Lidgren claim this is a natural phenomenon which takes place inside the earth and would account for the high temperatures maintained beneath the earth’s crust.

Lundin and Lidgren Predict COP of over 1000 Based on their LENR Theory
Posted on October 15
There is a section in their newly published paper that is both exciting and provocative (thanks to LENR G for pointing it out), as they look at the energy output potential for the model they propose. They refer to figure 9 in their paper which displays a simulation of a H2 + Ni58 reactor — which they say should give a much higher output compared to one using Li7, because it has a “lower spallation threshold.”
They write : Citation :
“Overall, the H2 + Ni58 reactor gives a higher performance. In fact, by combining wave input at frequencies closer to resonance with decreasing external power, (low-power mode) a new equilibrium may theoretically establish where the gain/COP may exceed 1000” (p. 8).
|
If this is actually true, the bar has been raised in terms of performance of LENR reactions. For many years people have been saying that a COP of even 10 with a LENR system providing megawatts of output, would be sufficient to revolutionize energy production, because it would mean LENR capable of efficiencies that would be much more competitive than those of fossil fuels.
If it is possible to reach COPs of over 1000, then we are on a different plane altogether, and really the sky would be the limit.
