It is shown in the NEDO project [1,2] that a nano-structured composite metal with hydrogen gas produces anomalous excess heat (AEH) when samples are heated to several hundred degrees. We have developed more convenient heat-generating method [3], using a multilayer composite metal thin film instead of the amorphous metal powder.
The method is superior as follows; easy to make samples, good reproducibility of AEH, easy to observe low-energy radiations. However, the values of the excess heat deduced so far include non-negligible reducible uncertainty, because the evaluation is based only on thermometry, the temperature of the sample core.
In order to reduce the uncertainty as well as to obtain much information on light emission, we are developing radiant calorimetry in which light radiation emitted from the sample is detected over a wide range in wavelength. Employed are a thermometer TMHK-CLE1350 (wavelength 3-5.5 µm) for midIR, an FTIR spectrometer Hamamatsu C15511 (1.5-2.5 µm) for near-IR, and a spectroscope Hamamatsu C10027 (0.3-0.9 µm) for visible light.
Extensive spectral measurements of light radiation provide visual evidence of excess heat power. One can see such an example in Fig. 1, which compares the two spectra measured with (red dots) and without (blue dots) H2 in the NiCu thin film sample heated by the input power of 34.5 W: the red dots exceed the blue dots over the entire region. This difference of radiant intensity is clearly the excess power due to the reaction involving H2.
Detailed analysis reveals the difference of the foil without and with H2 in other physical quantities more specifically: the temperature rises from 942K to 992K, the amount of radiation increases by 6.2%, the emissivity reduces from 0.144 to 0.124. The total excess power is evaluated to be 6.0 W, in this case.
In the present work, we show the result on two types of samples: (1) nanostructured Ni-Cu multilayer film deposited on a Ni plate and (2) pure Ni plate which is used as a substrate of (1). The heat flow analysis was performed based on the temperature measured at three points of the sample holder, the sample surface temperature, and the total radiant heat flow from the sample surface.
It was found that the excess power of 2 – 6 W was observed for the sample (1) and the total energy produced in 120 hours was 0.72 MJ that corresponds to 3.8 keV/H atom. Experimental details and results of measurements will be discussed in detail.

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.

Yeah, I knew all dat’.
Bump!
Unfortunately I can’t understand this. I’m guessing their experiment produced slightly more energy than it consumed?
re: “Radiant calorimetry of excess heat production in NiCu multilayer foil with hydrogen gas”
Mills went down this ‘avenue’ a few decades back with Nickel and Hydrogen; too bad these researchers can’t do a search for journal papers on that subject ... I would be quite surprised if they noted (cited) any of Mills’ work in their paper.
Too heavy a read after just waking up.
These experiments produce more heat than can be accounted for with known chemistry. The presence of nuclear products indicates that it is a nuclear process.
Celani and Focardi did a lot of work in Ni & H. No one really noticed until that guy Rossi came along.
Is this a different kind of low-energy nuclear reactions or rather a variation on a theme of experimental LENR reactions developed over the last years.
Let me picture this differently so you get what I mean. The cambrian explosion suddenly showed 10 plus body plans that had not been in existence before. They just appeared. To intelligent design paleontologists—this is evidence that new software from outside was plugged into the system much like one would update a computer with software. To atheist materialists—this development is a disappointment to their theory that evolution self evolves from ever simpler organisms.
Using the words I’ve developed above as metaphors—is the LENR experiment above another branch/variation from a single tree of LENR experiment(as in the atheist materialist view)of the LENR experiments or an entirely different kind of LENR reaction—as if it were an entirely new body plan of LENR energy that has suddenly appeared—that only goes by the name of LENR because that’s the result.

***Yes. It was quite surprising that LENR reactions were being seen in Ni/H back in 1992 or so, and very few people could replicate it. It was harder to get the reaction going but it typically yielded more output power IIRC.
All these LENR dudes are supposedly working towards an experiment that can be reproduced on demand. That’s different than replication. It’s more akin to the state of semiconductors early in the history of the technology, difficult to reproduce.
This professor has a very good series of videos on fission and fusion. He explains it in a way that even I can understand.
He talks about new technologies and new generations of reactors how they failed and new methods that are self limiting and much safer.

Mills comes up in the material for replications of Pons & Fleischmann.

This Title:
“Radiant calorimetry of excess heat production in NiCu multilayer foil with hydrogen gas”
Looks like one of those papers created with a random word generator.
I am not being sarcastic, just saying.
Rossi’s E-Cat:
https://skepticalinquirer.org/2019/05/rossis-e-cat-expose-of-a-claimed-cold-fusion-device/
This thread aint about Rossi. Just because he got mentioned doesn’t mean you get to hijack the thread. You have been asked multiple times not to engage on these LENR threads because your intention is to sideline scientific discussion.
Asked & answered: Threadjacking LENR about Rossi

You wanna talk about Rossi, feel free to open your own Rossi thread.
For those of us who have been following LENR the choice of words makes sense.

“It was found that the excess power of 2 – 6 W was observed for the sample (1) and the total energy produced in 120 hours was 0.72 MJ”
0.72 MJ over 120 hrs is only 1.7 watts. How can it be 2-6 watts excess power when the output is only 1.7 watts?
