Plasmonic Condensed Matter Nuclear Fusion
Katsuaki Tanabe Kyoto University, Japan E-mail: tanabe@cheme.kyoto-u.ac.jp
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.

” Pons and Fleischmann”
The guys that killed ‘cold fusion’
No one is as expert on this as Professor Tanabe. Suggest you do what real experts do....read his publications.
Whatever.
Did you send that email to Tanabe yet?
If you let people bother you, that’s your fault.
***No. Allowing tag team trolling is the fault of the moderation on forums. Whether or not it bothers ME is immaterial. It’s about doing the right thing. It was a mistake to allow such trolling on Certifigate threads, among other kinds of threads. It was also a mistake to allow it on LENR threads and that mistake is being corrected by the sidebar moderator.
I like science in general and LENR (among other things) in particular.
***So do I
Whether other people think that it’s dumb is of zero interest to me.
***That’s to you. There are others to consider beyond yourself, such as the dozens of lurkers who are turned off the subject due to the unfounded harsh criticisms, and the researchers whose careers have been adversely affected in an important area of research that could benefit the whole planet.
Lots of people thought what I’m doing is dumb, but now it’s getting traction and the whole situation is changing.
***Cool.
It’s taken more than twenty years, but it’s happening.
***What are you working on?
If the science is good, the results will come through.
***The science was good 30 years ago and the results did not come through. Science sometimes has to advance one funeral at a time.
The naysayers will be forgotten utterly, and their objections will even be forgotten by themselves.
***In the meantime they cause damage and it is right to counteract that damage.
Because the real purpose behind their actions is to censor the subject in not being posted AT ALL on FR.
Apparently I am the only one here discussing the science!
seagulling
The only seagull. One who has been asked multiple times to leave LENR threads.
Of course he didn’t email Tanabe. Because his interest is not in discussing or furthering science, his interest is in seagulling on these LENR threads.
Well, they're not succeeding at that, are they?
I mean, I read and appreciate every ping Kevmo sends me. Their dumb comments don't bother me at all. Actually, I find them somewhat amusing.
The cold fusion skeptics became old news a long time ago. Let them yammer and rave. Lots of capable people are getting results, and there's even a growing body of theoretical work on what's going in LENR at the scale of nuclear distances. So far no one has found the magic combination of preparation steps that results in someone vaporizing themselves and their lab in a sudden flash of light, but I think that might happen — or perhaps something a bit less dramatic — I just don't know when. Could be next month, could be in five years.
It's pretty clear that the effect has something to do with roughness at an atomic scale, which is why the experiments with pristine 99.95% palladium rods didn't work thirty years ago, and that deuterium loading levels much higher than those originally tried are necessary but not sufficient to see reactions. Some of the new experiments with nanoparticles (like those described in the paper that started this thread) look very promising, and that's exciting.
Genuinely new science generally takes decades to be accepted, particularly when it is as disruptive to the established order as LENR is. Many billions of dollars, and thousands of careers, have been invested in traditional "hot" fusion, and those people are going to have their whole world turned upside down if LENR can be made to work consistently in the laboratory. If a good theoretical model can be made that predicts its characteristics and enables it to be scaled up, it will change civilization, lead to large-scale political upheavals, etc.
Of course there are going to be naysayers. One must expect that.
Oh yeah? Hmm. What have you said so far? I looked over your posts, and don't see anything very scientific.
You emailed Tanabe yet? Be sure to let us know what he says in response.
he hasn’t gotten drummed out of his department yet.
***Like Duncan was?

“Oh yeah? Hmm. What have you said so far? I looked over your posts, and don’t see anything very scientific.

If it wasn’t scientific, you wouldn’t have said it was outside your expertise and I should email the author.
What a total BS artist you are!
Looks to me like Professor Duncan is doing pretty well for himself. He holds an endowed chair at Texas Tech, which last time I checked is a pretty good university. He left one faculty post and got another, better one. Good for him.

Abstract
We propose an efficient laser fusion ignition system consisting of metal nanoparticles or nanoshells embedded in conventional deuterated polystyrene fuel targets. The incident optical energy of the heating laser is highly concentrated around the metallic particulates randomly dispersed inside imploded targets due to the electromagnetic-field-enhancement effect by surface plasmon resonance, and thus effectively triggers nuclear-fusion chain reactions. Our preliminary calculations exhibit field enhancement factors of around 50 and 1100 for spherical Ag nanoparticles and Ag/SiO2 nanoshells, respectively, in the 1-µm band.
Now, imagine more than ten years of identical behavior...the agenda of censorship becomes obvious.
I've been following Kevmo for at least that long, including the interval he was banned. I guess should pay more attention to the dummies who try to gum up the works, although I know Texas Gator from elsewhere on the forum, he's a tarball. There are enough other people who are "Texas this" or "Texas that" that I lose track of which is which.
“What a total BS artist you are!”
I guess you now recognize your mistake.
You're not usually that honest.
