ICCF-19で発表のあった核変換実験について

「Nagel博士によるICCF-19の概要紹介」で取り上げたInfinite Energyの記事の中に、核変換に関する章があり、思っていたよりずっと多くの核変換実験の結果が発表されていたと知りました。ポスターセッションへ出展したものも多く、実験の信頼度はまだ十分ではないかもしれませんが、多種多様な実験で核変換を追っている人たちがいる状況には大きな可能性を感じますね。

主に自分のためのメモとして、核変換の記述部分を抜粋しました。日本語の部分は全て私による付け足しです。

Transmutations
At ICCF19, as at earlier conferences in this series, there were several papers on the results of LENR other than heat production.  Chemical analysis methods were used before and after experiments to gain evidence for transmutation reactions.  They are summarized in this section, starting with two poster papers related to radioactive isotopes.

Vladimir Vysotskii: 海泥(の中のメタン菌)を使った核変換実験(セシウム133⇒バリウム134)

Vladimir Vysotskii from the Kiev National Shevchenko University and three colleagues from Russia studied experimental transmutation of 133Cs to 134Ba in media supporting the growth of methanogenic bacteria from sea sludge. The microorganisms were cultivated under anaerobic conditions at 30°C in an aqueous nutrient medium. Controls had no sea sludge, that is, none of the bacteria thought to add a proton to the Cs to produce Ba. Samples from the cultures were drawn and analyzed at 48, 94, 144 and 192 hours. The data showed a monotonic decline in Cs and monotonic growth of Ba. The rate of transmutation was computed from the data to be about 10-6 synthesized Ba nuclei per second per 133Cs nucleus. That value is two orders of magnitude greater than the team’s earlier experiments with the same system. It is comparable to the rate for conversion of Mn to Fe obtained previously by the group. We note that the transmutation work described at ICCF19 with a non-radioactive isotope of Cs does not guarantee that biological transmutations, presumably due to LENR, can be used to remediate the radioactive isotope 137Cs. However, earlier experiments by this group showed the rate for bio-transmutation of 137Cs to be 10-6 synthesized 138Ba nuclei per second and 137Cs atom.

Leonid Urutskoev: 強磁場での電子殻変形によるアルファ崩壊(ウラン238の減少加速とヘリウム、過剰熱の検出)

Leonid Urutskoev and four co-workers from the Moscow Institute of Physics and Technology and the Prokhorov General Physics Institute reported on the possibility of induced alpha decay in heavy nuclei due to the deformation of electron shells caused by strong magnetic fields. They produced high-current electrical explosions of titanium foils in solutions of uranium salts. Mass, Gamma and Alpha Spectroscopies were used to monitor the results. Depletion of 238U was found to exceed depletion of 235U. 4He was measured in the gas phase, and “significant thermal heating of the explosion chamber was observed.” The authors stated that their results confirmed other experiments at the General Physics Institute in which laser ablation of 197Au nanoparticles suspended in a solution of uranium salts produced similar depletion of 238U. They attribute both results to the strong magnetic fields due to the high currents that exploded the foils. In their view, those fields “significantly distort the atomic shell and thereby initiated the α-decay.”

Ubaldo Mastromatteo: シリコンウェハー上にクロムで接着したパラジウム薄箔へのレーザー照射による核変換(O, Al, Si, Kの元素を検出)

In one, Ubaldo Mastromatteo from A.R.G.A.L. in Italy irradiated thin films of Pd on a Cr adhesion layer on a Si wafer in an H2 atmosphere with low power lasers. A 1 mW 633 nm laser and a 3 mW 403 nm laser were employed for the two-week irradiations. The samples were examined before and after the runs with a Scanning Electron Microscope having an X-ray analysis capability. The virgin samples had a few defects due to the evaporation process that produced the Pd films, and showed mainly X-ray peaks due to Pd and Cr. After the runs, the samples exhibited cavities around which “significant percentages” of light elements were observed. Strong X-ray lines from O, Al, Si and K were measured. The results were said to be similar to those of other researchers in “different contexts and with different materials.” If not due to contamination, the “nuclear fission hypotheses will have to be seriously considered.”

Max Fomitchev-Zamilov: 重炭化水素(Kendex 0842という油)からキャビテーションによって窒素と酸素を生成

Max Fomitchev-Zamilov posted a paper entitled “Apparent Synthesis of Nitrogen and Oxygen from Heavy Hydrocarbons: The Case for LENR.” He used 5.6 kg of the oil Kendex 0842, and degassed it at 80°C at 50 µHg for 5 hours to eliminate the possibility of atmospheric contamination.  Then, the oil was subjected to “extreme hydrodynamic cavitation” for some unstated time. That caused the production of 5 gm of N, which out-gassed to form 3.6 liters of gas. The 22 gms of O reported to be formed reacted with the oil to form resins. The author surmised that the production of N and O was due to LENR with addition of protons to carbon and nitrogen, respectively. No radiation or heat production was observed during the experiments.

A. Gromov: サーマイト反応によるCa(カルシウム)生成

A. Gromov and colleagues from Russia and Italy reported on the formation of Ca in reactions between Al and N in AlFe2O3 thermites. The combustion products from three types of experiments in which Al and N reacted showed “abnormally high concentrations of Ca (up to 0.5 mass %) as determined by Energy Dispersive X-Ray and Inductively-Coupled Plasma Mass Spectroscopies. In an experiment in which molten Al was jet sprayed into a N2 atmosphere, the increase in Ca content averaged 600% compared to the starting materials.
The authors posited a nuclear reaction and compared it to the chemical reaction of Al and N. 13Al + 7N gives 20Ca and about 5 x 1028 MeV per mole. This is about 10 million times the chemical energy of burning Al in nitrogen.

Renzo Mondiani:  炭酸カリウム水溶液で銅電極を使った電気分解での検出

Renzo Mondiani from Italy reported on transmutations by an electrolytic cell having copper electrodes. With a “low to medium” concentration of K2CO3, he reported the formation of 32S16 by fusion of two 16O8. However, in a “high concentration” of the solution, he determined that a fission reaction occurred, namely 39K19 – 16O8 → 23Na11. For intermediate concentrations, which reaction dominated depended on the size of the anode. The first reaction was primarily for small anodes and the second for large anodes. The results of the first reaction could be determined visually due to gas volume changes. In both cases, unstated types of chemical analyses were used to establish the reaction products. Those analyses also showed production of Mg, presumably by a fission reaction: 39K19 – 14N7 → 25Mg12.

F. Ridolfi: 鉄の棒に超音波を照射して生じた空洞にK, Cl, Cuを検出

F. Ridolfi from the Universita degli Studi di Urbino “Carlo Bo” reported on the results of ultrasound irradiation of iron and steel bars. Damage to the sample surfaces, neutron bursts and observation of unexpected elements resulted from the ultrasound. The cavities were less than or about 10 µm in diameter. K, Cl and Cu were found, and the 63Cu/65Cu ratio was in the range of 0.3 to 1.7, rather than the normal value of 2.2.

D.S. Baranov and O.D. Baranov: ビスマス塩への強電界適用後に様々な核種を検出

D.S. Baranov and O.D. Baranov from a private laboratory INLEAS in Moscow did experiments on application of “strong” electric fields to bismuth salts. They gave the following summary of results, but did not cite the analytical methods employed to determine these values: “The elemental composition of substances emitted from the sample was radically different from that of the initial bismuth salts.
There were found some different elements: carbon (up to 90%), zinc (up to 6%), potassium (up to 2%), calcium (up to 2%) and aluminum (up to 5.5%),” plus tin and titanium in unspecified amounts. The authors interpret these results as evidence for “giant long-lived nuclear molecules” and state further that “It is assumed that in nuclear molecules some nucleon transfers are possible.”

岩村康弘博士の常温核融合研究が日経新聞に報じられる

日本経済新聞が、三菱重工業の岩村康弘博士の常温核融合研究を紹介する記事を載せました。マスメディアが常温核融合を報じるのは一体何年ぶりでしょうか。岩村博士の研究自体は常温核融合研究者の間では著名なものですが、こうやって記事になったのは画期的だと思います。


さて、記事の中に以下のように記載があるのは、MITで開催された常温核融合コロキウム2014の事でしょう。
3月下旬、米ボストンのマサチューセッツ工科大学の講義室。世界から集まった100人以上の研究者を前に、三菱重工・先進技術研究センターの岩村康弘インテリジェンスグループ長は「元素変換はマイクロ(100万分の1)グラム単位で確認できた」と報告した。多数の質問を受け、同社の実験を説明する理論の提案も数多く発表されたという。
この時の岩村博士の講演動画は以下で見られます(Cold Fusion Now!に感謝)。


「様々な手法で重水素の濃度を高めることで、新しい元素の収量がナノグラムからマイクログラムへ3桁増えた。測定精度も上がり、1平方センチメートル当たり最大数マイクログラムの元素変換を確認したとしている」と書かれています。近年、実験手法が改善されて効率が上がってきたようです。発表原稿には以下のような進化の図が示されています。


今回は、以下の2つの処理法を新たに追加されたようで、特に後者で顕著な効率の改善が見られたようです。



また、昨年、豊田中研の日置博士が追試論文を発表された事にも言及するページがありました。海外のウォッチャーから見ると、「三菱」と「トヨタ」という大企業が常温核融合に取り組んでいるのは、タイヘンな脅威に映るようです。

しかし、記事の最後に以下のように指摘されているように、企業として大きな投資をしてきた訳ではなく、岩村博士の情熱によって辛うじて研究を継続してきたのが実情ではないかと思います。尤も、継続して来ただけでも偉大な業績ではあるのですが。
3年前の東日本大震災。放射性物質を拡散する東京電力福島第1原子力発電所の光景を前に、ある三菱重工業関係者は「元素変換をもっと大規模に研究していれば」と叫んだ。三菱重工は約20年、元素変換を研究してきたとはいえ、予算も人員も「細々と何とか続けてきた」というのが実情だ。
世界で常温核融合が注目を集めるようになった現在、この記事にあるように放射性廃棄物の無害化に向かって研究を加速していただきたいと願っています。

NanoSpire社のキャビテーションによる過剰熱と常温核変換

キャビテーション技術を使ったビジネスをしているNanoSpire社は、従来からキャビテーションによって常温核融合現象が起こっていると主張しています。以前から、具体的にどのような現象が起こっているのか知りたいと思っていたのですが、実は、ホームページのFusionというページに概要が記載されていました。

自分のための備忘録として簡単にメモしておきます。まず、以下の文中で、キャビテーションを起こすLeClair Effect reactorで、840 Wの入力に対して2.9 kWの出力となる過剰熱を検出したと述べています。しかも12回の実験で100%の再現性があったとの事。
In March, 2007 Mark LeClair built and tested the first cavitation reactor powered by the LeClair Effect, based on our patented technology. More research was done from 2007 to 2009 with a variety of other reactor designs that led to a series of key experiments performed from July – August, 2009 under a grant, titled: Utilization of Crystallized Cavitation Reentrant Jets for Zero Point Energy Production. The goal was to produce a next stage hot water heater reactor based on the LeClair Effect and was awarded by a potential investor focused on promoting cold fusion. Mark LeClair and Serge Lebid discovered that the scaled-up LeClair Effect reactor was triggering intense fusion, fission and large scale elemental transmutation using ordinary water. The 1.25” ID by 12” long reactor produced 2.9 kW of hot water using only 840 watts of input, a coefficient of performance (COP) of 3.4 times more energy out than in. The water temperature was raised an average of 18 degrees C (32 degrees F) average passing through the reactor with 28 degree C (50 degrees F) temperature spikes observed. A total of twelve experiments were performed, with 100% repeatability of the high levels seen in excess heat and transmutation in the various configurations.
また、これに先立つ以下の部分で、水の中にO-H結合の繰り返しによる結晶構造(ファンデルワールス結晶?)があると述べられています。これが気になるのは、攪拌振動しながら(たぶんキャビテーションを起こしている?)水を電気分解して生成するオオマサガスでも、水分子のクラスター構造があるとする分析が出ており、同じ事を言っている可能性があると思ったからです。
The crystal has an equilateral triangular cylinder subunit that most commonly forms jet hexagon cross-sections. The crystal is a series of repeating O-H bonds along its axis and is bound by hydrogen bonds in the cross-sectional plane, a type of hybrid bonded crystal known as a van der Waals crystal. 
更に、以下の文章では、核変換が起こっているらしい証拠として、元素分析により34種類から78種類の(元には無かった)元素が検出されたと言っています。この分析に、Edmund Storms博士が絡んでいたのも驚きです(Edmund博士は常温核融合研究者として著名です)。
The large scale transmutation of elements was verified by three separate independent scanning electron microscope elemental analysis (SEM-EDAX) of the transmuted material, including University of Maine, Orono Laboratory for Surface Science & Technology (SEM-EDAX & XPS under contract), by courtesy of Media Sciences, located in Oakland, New Jersey and by courtesy of well-known Low Energy Nuclear Reaction (LENR) researcher and advocate Dr. Edmund Storms, formerly of Los Alamos in New Mexico. The University of Maine, Orono Chemistry Department also performed an analysis known as XPS that measured nucleus binding energy, confirming that the glassy coating seen covering much of the reactor cores was diamond. The SEM analyses collectively detected a total of 34 elements ranging from carbon to polonium. The same samples analyzed by SEM-EDAX and XPS were also analyzed with laser ablative inductively coupled plasma mass spectroscopy (LA-ICP-MS) by Shiva Technologies (an operating unit of Evans Analytical Group) located in Syracuse, NY. The more sensitive LA-ICP-MS detected a total of 78 elements ranging from lithium to californium and 108 isotopes ranging from 7Li to 249Cf, a standard detection set that does not include all the possible isotopes, but including most of the stable isotopes and many short and long lived radioactive isotopes. Together, the five analyses showed that nearly every element in the periodic table was detected in every type of transmuted particle in different distributions, up to the limit of the LA-ICP-MS detection range, californium.
