Plasmonic Condensed Matter Nuclear Fusion

The intensity and density of the triggering energy supplied to activate the nuclear fusion reaction are key factors to produce a smooth and reproducible initiation of the reaction. We previously proposed and numerically analyzed a scheme to provide high-density optical or electromagnetic energy to fusion-fuel materials by lasers and plasmonic field-enhancement effects, to significantly increase the reaction probability [1–6].

Large degrees of field enhancements, or energy focusing, were observed around metal nanoparticles and nanoshells [1], planar metal surfaces [2,3], metal/oxide interfaces [5], sharp metal tips [4], and metal nanogaps [6]. Strikingly, the field enhancement factors for hydrogen-absorbing transition metals, Pd, Ti, and Ni, can surpass those for noble metals in the microwave region [3,4].

This electromagnetic boosting effect may have unconsciously benefited the experiments reported so far, particularly for the electrolysis-type ones, and its active utilization with proper choices of materials, structures, and operating conditions can improve condensed-matter fusion systems further. Gas-phase experimental research in quest of condensed-matter fusion is underway by using multilayered deuterium-containing Pd plates.

In our experiment, we in particular directly apply a bias voltage across the Pd sample to provide a current injection through Pd, to stimulate the nuclear reaction by Joule heating, also anticipating strong electrodiffusion or electromigration, in addition to the conventional deuterium diffusion induced by pressure/mass-concentration and thermal gradients. We installed multiple kinds of lasers in the gas-phase D–Pd reaction system to irradiate the Pd samples coated with noble metal nanoparticles, as energetic stimulation support, potentially with a boosting plasmonic local field-enhancement effect.

We simultaneously observed a sudden temperature increase with an overshoot and a neutron signal. Significantly, we observed a clear signal of substantial-amount 4He generation from the Pd samples as a shoulder peak on the D2 peak, and a possible 3He signal, via in-situ mass spectroscopy [7].

We also observed a sudden burst of these gas species out of the Pd sample. Our results might indicate a certain anomalous nuclearrelated reaction in the D–Pd system.

What type of lasers and what was power density?

[Steely Tom]

Thanks Kevmo.

Look at the video linked by Kevmo in his first comment. The answer to your question can be found from 1:08 to 1:41 in that video.

Updated No Internal Trolling Rules for FR per Jim Robinson

https://freerepublic.com/focus/f-news/3928396/posts

If someone says stop, then stop. Do not enter onto a thread on a topic you don’t like just to disrupt, rattle cages, poke sticks, insult the regulars, or engage in trolling activities, etc. ~Jim Robinson

This topic has a following, people who wish to learn and discuss the materials presented.

Please refrain from posting anything that doesn’t legitimately address the issue.

Something is going on in this segment of science. There are a considerable number of research groups studying the matter. -Sidebar Moderator

The issue isn’t whether we allow skepticism, it is whether we allow hyperskeptics and skeptopaths to ruin the scientific dialog. Civil discussion of the involved science is desired.

Why not address your question to Professor Tanabe?

[Kevmo]

Because he would rather seagull on these LENR threads with the pretense that he’s diving down on some technical point.

[TexasGator]

“Why not address your question to Professor Tanabe?”

I thought we had experts here.

Doesn't bother me, but I'm not the author of the paper.

Katsuaki Tanabe is not only a professor of chemical engineering at Kyoto University, he's also a Google scholar.

Perhaps he only fooled Google into believing in him.

[Steely Tom]

I’m an expert in some things, but not in the research described in this paper. But you can easily contact the guy who actually did the research. Why not do it? He seems to speak English pretty well.

[Kevmo]

I searched ‘google scholar’ to find out what that means to be a google scholar and it was not helpful.

[Kevmo]

See what I mean? Seagulling.

[Steely Tom]

I don’t know either, but I’ve talked to a Google scholar on several occasions for my job, and I can tell you he’s a damn smart guy.

[Steely Tom]

See what I mean? Seagulling.

Ok, but why do you let it bother you? I'm real interested in LENR and condensed matter physics in general. I had to take a few courses in the subject to get a masters in EE, and I liked it and pretty much understood it, although that was right around the time Pons and Fleischmann's original announcement was made, and long before anyone heard of Mike McKubrey, Ed Storms, Peter Hagelstein, CR39 experiments at SPAWAR, and other people and matters related to the subject.

[Steely Tom]

Let whatever other people want to think about the subject be their business. LENR is going to prevail if it’s for real, and it looks more and more like it is for real with every passing year. There sure are a lot of people experimenting with it, getting neutrons, generating tritium, seeing excess heat effects. There’s even another guy at MIT who’s working on it (other than Hagelstein, I mean) and he hasn’t gotten drummed out of his department yet.

[Kevmo]

I put up with their abuse for a decade. That’s long enough, far too long to ask a freeper just to be patient. When they engage in tag team trolling, it’s an abuse of the forum. I’m applying the learnings from another issue where tag team trolling was allowed, on a very distinctly constitutional issue on this constitutionalist website... https://freerepublic.com/focus/f-bloggers/2168149/posts

[Steely Tom]

If you let people bother you, that's your fault. I like science in general and LENR (among other things) in particular. Whether other people think that it's dumb is of zero interest to me. Lots of people thought what I'm doing is dumb, but now it's getting traction and the whole situation is changing. It's taken more than twenty years, but it's happening.

If the science is good, the results will come through. The naysayers will be forgotten utterly, and their objections will even be forgotten by themselves.
