Paper: “Peculiarities of hydrogen absorption – Nd90Fe10” (Vladimir Dubinko)

Thanks to Alan Smith from Looking For Heat, who has shared with me a new paper written by Ukrainian scientist Vladimir Dubinko titled “Peculiarities of hydrogen absorption – Nd90Fe10”

The article is published on the Looking For Heat website here:

Here is the abstract:

A fierce exothermic reaction was detected in Nd90Fe10 films with sufficient degree of amorphous phase upon filling them with hydrogen or deuterium, which resulted in the melting of the samples and the Cu foil, in which the samples have been wrapped. Quantitative analysis have shown that the amount of heat produced in large Nd90Fe10 samples in our experiments is 80÷100 kJ per g of hydrogen, which cannot be explained by DSC [Differential Scanning Calorimetry] data on the heat produced in small samples under different heating-cooling balance. Possible reasons for the discrepancy are discussed including low energy nuclear reactions taking place at the initial stage of hydride formation.

Dubinko notes:

One of the possible explanations of this discrepancy is based LENR taking place at the initial stage of hydride formation, when 80÷90% of amorphous phase in the films produced LAVs [5-10] that triggered LENR. Subsequently, the amorphous phase transforms to crystalline hydrides where the LAVs do not form, which stops the LENR. Upon cooling, various hydride phases are observed by X ray analysis: NdH2 (fcc) and Nd2Fe17H4.8 (hcp).

In order to initiate LENR, it is desirable to make the hydrogenation directly under irradiation and to measure the response to such combined treatment. This problem needs further investigations.
