    Monitoring Active Sites for Hydrogen Evolution Reaction at Model Carbon Surfaces

    Regina Kluge, Richard W. Haid, Ifan Stephens, Federico Calle-Vallejo and Aliaksandr Bandarenka

    Abstract

    Carbon is ubiquitous as an electrode material in electrochemical energy conversion devices. If used as support material, the evolution of H2 is undesired on carbon. However, recently carbon-based materials are of high interest as economic and eco-conscious alternative to noble metal catalysts. The targeted design of improved carbon electrode materials requires atomic scale insight into the structure of the sites that catalyse H2 evolution. This work demonstrates that electrochemical scanning tunnelling microscopy under reaction conditions (n-EC-STM) can monitor active sites of highly oriented pyrolytic graphite for the hydrogen evolution reaction. With down to atomic resolution, the most active sites in acidic medium are pinpointed near edge sites and defects, whereas the basal planes remain inactive. Density functional theory calculations support these findings and reveal that only specific defects on graphite are active. Motivated by these results, the extensive usage of n-EC-STM on doped carbon-based materials is encouraged to locate their active sites and guide the synthesis of enhanced electrocatalysts.

    Whether Cold Fusion or Low-Energy Nuclear Reactions, U.S. Navy Researchers Reopen Case

    Spurred on by continued anomalous nuclear results, multiple labs now working to get to bottom of story


    After more than three decades of simmering debate in specialized physics groups and fringe research circles, the controversy over cold fusion (sometimes called low-energy nuclear reactions or LENRs) refuses to go away. On one hand, ardent supporters have lacked the consistent, reproducible results and the theoretical underpinning needed to court mainstream acceptance. On the other, vehement detractors cannot fully ignore the anomalous results that have continued to crop up, like the evidence for so-called “lattice-confinement fusion” adduced last year by a group at NASA’s Glenn Research Center.


    Scientists at the Naval Surface Warfare Center, Indian Head Division have pulled together a group of Navy, Army, and National Institute of Science and Technology (NIST) labs to try and settle the debate. Together, the labs will conduct experiments in an effort to establish if there’s really something to the cold fusion idea, if it’s just odd chemical interactions, or if some other phenomenon entirely is taking place in these controversial experiments.

    An article in Tohoku360, what looks like a citizen local journal, about CleanPlanet

    https://tohoku360.com/cleanplanet/

    Translated by Google

    https://translate.google.com/t…u360.com%2Fcleanplanet%2F


    The article is not very technical, presenting the motivation of the founder President Yoshino , Professor Iwamura, the context ...


    I note the technically interesting section (translated)

    Professor Iwamura and his colleagues named the energy generated from this condensed nuclear reaction "quantum hydrogen energy" and established a unique heat generation method. We have developed a small generator that occludes light hydrogen in nanoscale nickel and copper and stimulates it under certain conditions to cause a condensed nuclear reaction to generate electricity. A demonstration machine capable of generating 100 watts has already been completed, and a demonstration machine capable of generating 1 kilowatt is scheduled to be completed by the end of the year. Representative Yoshino said, "The demo machine is one of the core models for scaling the business from now on. Based on this, we will make a model that can generate 100 kilowatts and 1 megawatt in the future to solve the world's energy problems. I want to solve it all at once. "

    Generators using "quantum hydrogen energy" are currently being talked about with companies in all industries, such as installation in electric vehicles, building power supply equipment, and introduction as new energy in cities. Professor Iwamura said, "If you want to install it in a car, you need something that is resistant to vibration, and if you introduce it as a building power source, you need more power generation than size. We are in the starting stage for this. "

    The business paragraph promotes cooperation and mass diffusion...


    The about of Tohoku360 says that (google translated)


    TOHOKU360 is a participatory news site that conveys the present state of Tohoku to the world with the hands of everyone living in Tohoku. Experienced media-born "editors" and residents' "correspondents" living in the six prefectures of Tohoku work together to discover valuable news that is not yet known from their own feet, nationwide. I will send it to the world.

    Saying the blackout is because of failing gas backup, is absolutely true but misleading.

    It is admitting that the power worst-case-expected from wind ansdsolar is , as most know in the domain, null or negligible.

    EDIT: wind expected 24% of capacity, but delivered from 2 to 18% of capacity. Solar better not talk about it.

    Image

    Intermittent renewable without massive storage is just a fuel-saver and cannot reduce by a noticeable amount the capacity of controllable source like hydro, nuke or fossils.

    Since nuke is controllable (we do load-following in France, helped by hydro of short term unexpected variations, and wind/sun is really challenging that capacity to adapt, not load)

    1WG of intermittent renewable requires 1GW of fossil backup and saves 20-30% of fuel.

    With nuke, 1GW of intermittent renewable require 1GW of nuclear power, and cost few percent of efficiency and maintenance cost... it is either virtue signaling or just crook financing.


    Another cause of the Texas blackout is also the fact that it's grid is isolated for regulatory reasons.

    It is absolutely true that with the help of all the gas, coal, oil, nuke, even solar, wind energy from all USA/Canada/Mexico it may have sustained the heavy load, provided the powerlines don't trip (like they menace in EU).

    But this is destroying the myth of local energy that intermittent energy love to spread. Nuclear energy is very local, very dense, and hydro is less but sure is, like fossils. But intermittent renewable are based on "foisonnement"(French - dunno the translation, mean when you benefit from uncorrelated production over a wide zone), but this "foisonnement" is nearly mythic in EU grid, as anticyclone can cover, like winter do, the whole Europe. It was estimated, and at best from Spain to Poland, insert trillion$$ in powerlines, it is about 10% of capacity.

    In fossil dominated electric mix, you can indeed save 20-30% of fuel with an intermittent renewable similar power installed capacity.

    To make intermittent renewable useful in a no-fossil mix, the only solution is huge, mega huge sized dams (STEP). It is proposed as a "hard engineering" challenging proposal " to drown the valley of French city "Grenoble" to store a massive amount of daily solar and some wind energy... A few of this valley should be drowned like the Chinese 3 Valley dam, and some propose the valley of Chamonix...

    STEP-de-Grande-Abondance-en-France-3.jpg


    The cost and volume of storage as battery is above any realism.

    Most engineering proposal like concrete blocks and crane are not much better, even if you accept feasibility.

    I'm ok with intermittent renewable energy, provided it is sold with the matching storage, in power and in energy capacity.


    Hydrogen power to gas plan are not much realistic according to many engineers, even if you plug them on non-intermittent power... It seems the real plan behind the buzz is to make hydrogen from Russian and US Shales gas.


    I hope LENR will stop that crazy fashion and ruin the crooks behind.

    As ignorant I ask a naive metalurgy question:

    is there a way to design a material with adjustable crack size as Edmund Storms theory requires?



    I have an idea, using nanopowders of variable size, but stable structure, that when treated a stable way (eg: H2 loaded, heat treated, mechanically treated), will have cracks linked to the particle size ?


    Or more simply as you propose, hammered, heat shocked...


    Another way seen in a French article by Didier Gras about an industrial incident, would be to use cathodic sputtering, controlling time, intensity, or substrate structure ?


    Controlling the size of cracks would be great to test Edmund Storms theory...

    Very interesting for LENR


    • First lesson: It's not the idea that counts, but its acceptance
    • Lesson Two: Provide Multiple Pathways to Success
    • Third lesson: be aware of the limits of large programs
    • Fourth lesson: the incredible power of human intelligence.
    • Fifth lesson: Questioning French mental models

    maybe it would deserve to be put in a separate thread... Up to the mod if they feel

    Using Palladium Nanocubes on ZnO Nanostructures in Hydrogen Gas Sensor for Fast Response and Recovery Time


    https://www.ingentaconnect.com…0000021/00000004/art00046

    Quote


    We developed a novel sensor structure by synthesizing Pd nanocubes (NCs) decorated on ZnO nanostructures (NSs) applied to resistive-type H2 gas sensor with micro-length in sensing channel. The ZnO NSs were selectively grown between micro-size finger-like interdigital electrodes through microelectromechanical technology. The novel H2 sensor structure with the sensing channel was reduced to micro-size by this proposed method to obtain a sensor with fast response/recovery time. The as-prepared structure exhibited robust sensing performance with a response of 11% at optimal temperature of 150 °C, good linearity, and fast response/recovery time within 10 s. The speed of chemisorption through the diffusion pathway in Pd NCs combined with micro-length in sensing channel in sensor showed fast response and recovery times of 9 and 15 s, respectively, toward 10,000 ppm (1%) H2 at 150 °C. The result showed approximate linearity response in H2 concentration range of 5÷10,000 ppm and a large operating temperature range from room temperature to 200 °C.
