Ni and Pd have NO METASTABLE isotopes
Does that happen to imply that they may have short lived isomers or resonances?

Secondly, I'm curious if anyone has any suggestions about where to get components, how to coat the nickel electrodes with platinum,
Vacuum deposition, if that was not obvious already.
Not saying electroplating is impossible.... chloroplatinic acid.... See "platinic chloride" in Merck Index for
a couple of references.

Its galvanic corrosion
OK, then how did it continue far beyond the creation of an open circuit?
-
Those steel clips are fairly well known to corrode. There are, or were, stainless steel clips, similar to the ones pictured.
I bet there are plastic clips that won't complicate your chemistry at all.

What is interesting that the paper is written by Russian scientists originally.
Yes, very interesting link. I see on p. 4, figure 1, there is a substantial and rapid temperature rise at about minute 30. That anomaly might suggest some special exothermic process (LENR?) occurring and then apparently disappearing. Or is that simply a quick absorption due to cracking as a particular stress is reached?

Hey "can" thanks for the table and reference. But, I see some elements in the above table of hydride and non-hydride forming elements that must be questioned. For example, Si, silicon forms a very well known hydride, that is silane (SiH4), and there is the analogous "germane" (GeH4), both of which are analogs of methane (CH4). In the next column there are the known analogs of phosphine (PH3), that is arsine and stibnine (the hydrides respectively of arsenic and antimony (or stibnium in latin). These are essentially analogs of ammonia, that is NH3. Further, one might understand halogens as forming hydrides, those all being acids of course, although HF is a weak acid, HCl, HBr and HI are strong acids. The latter, HI may have enough anomalous energetics to be considered as a candidate for participating in possible LENR processes. Even oxygen has both an OH- and H2O "hydrides", and to be sure OD-, is likely essential to F-P CF.
I guess the dark blue elements with their positive heats of formation are effectively metastable, and effectively require energy input from the environment to be formed. Whereas the red elements tend to form giving off heat as enthalpy.
Another interesting table would be that showing the Gibb's free energy (delta G = delta H minus T delta S) , the more informative delta G giving a clearer view of the degree to which the hydride formation is spontaneous or not.

Seems to bring up nothing for me. Please check your link. Thx.

Yes, extreme caution with Hg vapors. But that does not preclude the possibility of doing those experiments. The main precaution would be a completely enclosed system, and a secondary enclosure around that. Tertiary protection, that is a separate respiration system for any personnel involved, as well as a complete suit to avoid transdermal exposures as well.
Remember Lavoisier was able to experiment with mercury, and only died because he got on the wrong side of the guiillotine. Likewise, Newton, head of the Royal Mint, physicist of highest rank and co-inventor of the calculus, was retrospectively thought to be intoxicated by mercury from his own experiments with "hydroargyrum = Hg".
I understand the starting point for many alchemical experiments was mercury in the quest to synthesize gold. Likely at least one of the motivators for both Lavoisier and Newton to mess with the stuff.
It is but a curious speculation that neurotoxicity might have enabled some "genius" insights.... Nicotine enhances learning, why not a little Hg? (Don't try either one, please!)
-
Well, maybe there is gold in it, literally: Hg to Au, analogous to Bi to Pb. Now we are getting very alchemical....
-
But the difference is that Pb implies fission, Po implies fusion. Regardless, a pulse driven transmutation at a high percentage is phenomenal. Such, if verifiable, would have implications for many other transmutations...
-
Bismuth to lead? Loss of a proton? What is this, electrostatic pulse-driven fission?
-
Thanks Can, for dredging that up. It's been a long while since I have thought about Ogfusionist's phenomenological experiment. I hope it is useful to experimenters.

Nickel Carbonate is light green and paramagnetic, and will not retain magnetism. Stainless steels are typically 15-20% Nickel.
Didn't Ogfusionist, ~3 years back make some considerable case for nickel carbonate in his reported observations. Or was that my own deduction based on his description? Briefly, Ogfusionist had observed that FibreFrax containing some nickel of a particular oxidation state, when raised to a particular temperature in the presence of dry hydrogen, led to a spontaneous thermal runaway that melted or otherwise fused the fibrefrax substrate.

These machines would be proteins molecules.
Could be. But no guarantee. The elaboration of transition metal chemistry by addition of biochemical structure, let us say by "proteins" is less clear the more primitive the such a structure might be. For example, tetrahydropyrrole / porphyrin surrounding iron, magnesium or cobalt in respectively heme, chlorin or cobalamin. Look at the structure of cytochromes. Surely very deep in biological evolution, and sure enough, the least like "proteins" of common "modern" (last 3.6 X 10^9 years) enzymes surrounding and enhancing their presumed antecedent metallic co-factors, or functionally enhancing their metallo-porphyrin core functionality. The question might be, was there an era of "chemical evolution" that pre-dates the evolution based on our current molecular biology. The evidence is quite clear that other paradigms of biological evolution could easily have preceded the present DNA > RNA > protein scheme. "RNA world" has had quite a play in biochemical evolutionary theory. But even before that hypothetical era, there may well have been transitory precursors before chemical evolution gave way to biological evolution.

Radon can turn to Pb inside your lungs while firing a harsh gamma or more through (hopefully, not into) a lung or two.
Yes, but more important biologically, carcinogenically, is the daughter alpha production. Radon has a multiple path decay route. Rarely is radon itself the culprit with its beta decay path (low LET), it is the various daughter products that are all radioactive, and several are alpha emitters (high LET). These have an array of half lives that are of course typically charged products. They are metallic solids in bulk. I suspect as individual ions they may have far lower fugacity than radon. As charged "subnano"-particles, they attach themselves to surfaces and to dust motes in the ambient or in tissues. They can be deposited deep within the lung, especially if they are in a critical size range that is likely to land beyond the ciliary / mucosal expulsion machinery of a healthy lung. It is widely thought that the decays that produce alphas are by far the main risk in radon exposure, these are seen in Pb-214 and Bi-214 which are themselves products of the initial radon decay.
See this brief radon outline that does not include all the decay paths, but the ones considered big health risks:
http://www.radonguide.com/radon-decay-chain.html
It may be beneficial to recall that the energetic product of some LENR reactions can also be alphas at MeV energies. Please make certain those are not somehow produced in one's lungs instead of in whatever "reactor" one is experimenting with.
-
Best to keep in mind that the LET, "linear energy transfer", of such gammas is very insignificant from a biological standpoint. The chance of such a gamma producing the necessary multi-hit effect in a single cell is remote if not impossibly small. Multiple hits on a single cell are necessary to transform a cell into a fully dys-functioning progeny for the eventuality of lethal tumor development. It is a ironic that the highest LET is seen with alphas, which are otherwise thought to be quite harmless from external exposure. But not so, in an intra-cellular context. The alpha emitter can indeed produce multiple radical species within a single cell. Perhaps not "much" of a problem as a "one off" but definitely a risk from a statistical standpoint when taken over trillions of cells repeatedly exposed. The lesson: do not ingest or otherwise allow alpha emitters to reside in one's cells. Gammas, relatively OK, and K40 is the ready example that has been with us from the "beginning". It's a numbers game that can be confusing.

The limit for classic deep electron orbits is 3.43pm where the stored magnetic energy is equal to the potential gain.
There is a stable deep magnetic orbit at around 2.15pm as measured by Holmlid. To understand this you need to be able to work in 4D homogeneous space. Further you must model the electron as magnetic flux around the proton.Can these deep orbits be related to the Lipinski's UGC theory in any simple or quantifiable way? Last I looked at the Lipinski's theory, I recall they predict a "window" for low energy proton + Li 7 interaction at ~223 eV based on their Bessel function minima, and their extensive empirical results suggest high cross sections down to 100 eV, but less effective as one moves up, especially above 2 to 3 keV?.

As long, as Rossi does not fall under this category, modern science is performing well..
IobseRvable: hmm, so Rossi is THE paragon of evil? So only one "devil" needs extirpation in this era, and all in science and technology will be well for the foreseeable future.....?

dropped his physics degree
Personally, and as an amateur physics afficionado, I find this first paper to be a beautiful exposition (and will eventually read the others). I first became aware of the use dimensionless "natural unit" equations in my 1990s professional training, under the rubric of Henry's Law with respect to "global distillation".
To "Lobster": What should we think of the role of character assassination in modern science?

Re: alkali or other hydrides. Do not assume classical "collisional" physics branching ratios--- many, or even all, of us likely do not actually understand the transition states / intermediate steps for the low activation energy paths and outcomes implied there.
Again, caution, small and shielded might be an important safety consideration--- A suddenly "successful" 1000 X (or far more) of peak power (whether alpha or not). Risky for unprepared amateurs or even unprepared professionals.
Think: 'unreported catastrophic "failures"'.
