  • Hydrogenation without H2 Using a Palladium Membrane Flow Cell

    Electrocatalytic palladium membrane reactors (ePMRs) use electricity to hydrogenate organic molecules at ambient temperature and pressure. These benign reaction conditions position ePMRs as a sustainable alternative to thermochemical hydrogenation, which requires high-temperature and high-pressure reaction conditions. However, ePMRs suffer from slow reaction rates and a limited understanding of the factors that govern reaction performance in these devices. In this work, we report the design and validation of an ePMR flow cell. This flow cell increases reaction rates 15-fold and current efficiencies by 30% relative to H-cell reactors. We use this device to reveal that the hydrogen content in the palladium membrane governs the speed and selectivity of hydrogenation reactions, while the amount of hydrogen gas evolved at the palladium surface is deterministic of current efficiency. We contend that this flow cell, which enables hydrogenation without hydrogen gas, is an important step for translating ePMRs into practice.…cle/pii/S2666386420301041

    From cold fusion to pharmaceuticals

    Revisiting "cold fusion" led us to discover the electrolytic hydrogenation/deuteration reactor that is electrically-driven and uses water as a hydrogen/deuterium source. This technology opens new avenues for using renewable energy to make valuable chemicals, including pharmaceuticals.

  • I am happy to read another useful application of the research on LENR by the team of Pr. Berlinguette in NATURE CATALYSIS.


    Years ago, we have demonstrated that our palladium cathodes were producing atomic hydrogen. It is probably the reagent of Berlinguette team.…rium_by_palladium_cathode

    In this article, we published the deuteriation of benzoquinone into hydroquinone by a palladium cathode. Our goal was not to do chemistry, but to make paper that changes color on contact with atomic hydrogen. (or in contact with atomic deuterium) (I write « palladium » by mistake instead of "deuterium" in my previous post, sorry.)

    We present an apparatus that allows for the simultaneous measurement of mass change, heat evolution, and stress of thin film samples deposited on quartz crystal microbalances (QCMs). We show device operation at 24.85 ± 0.05 °C under 9.31 ± 0.02 bars of H2 as a reactive gas. Using a 335 nm palladium film, we demonstrate that our apparatus quantifies curvature changes of 0.001 m−1. Using the QCM curvature to account for stress induced frequency changes, we demonstrate the measurement of mass changes of 13 ng/cm2 in material systems exhibiting large stress fluctuations. We use a one-state nonlinear lumped element model to describe our system with thermal potentials measured at discrete positions by three resistance temperature devices lithographically printed on the QCM. By inputting known heat amounts through lithographically defined Cr/Al wires, we demonstrate a 150 μW calorimetric accuracy and 20 μW minimum detectable power. The capabilities of this instrument will allow for a more complete characterization of reactions occurring in nanoscale systems, such as the effects of hydrogenation in various metal films and nanostructures, as well as allow for direct stress compensation in QCM measurements.

  • Very elegant work TG - but surely we are at a stage now to think about building larger reactor systems? Especially since NASA's latest results using Pd/Ag wires? Or are you simply ignoring Holmlid's groundbreaking work like most other conventional physicists clinging to the Standard Model? I just don't get it.

  • Maybe I should bang on about this a bit more - you see the ITER reactor is being designed to re-create the conditions of the sun without one essential ingredient - the high gravitational field of the sun which functions to compress and contain the fusion reactions and reactants. All I am proposing is replacing that gravitational field with known catalysts and heavy metal proton donors and acceptors functioning as nuclear oscillators eg between Pd and Ag in a simple quartz plasma tube running up to only 10,000 degrees max. Stimulate with sinewave AC at Terahertz resonant frequency between pure Fe plate electrodes. Include the essential catalysts for forming Rydberg matter (UDD) and there you have it cold fusion in a tube!

  • Microwatt-Resolution Calorimeter for Studying the Reaction Thermodynamics of Nanomaterials at High Temperature and Pressure

    Calorimetry of reactions involving nanomaterials is of great current interest, but requires high-resolution heat flow measurements and long-term thermal stability. Such studies are especially challenging at elevated reaction pressures and temperatures. Here, we present an instrument for measuring the enthalpy of reactions between gas-phase reactants and milligram scale nanomaterial samples. This instrument can resolve the net change in the amount of gas-phase reactants due to surface reactions in an operating range from room temperature to 300 °C and reaction pressures of 10 mbar to 30 bar. The calorimetric resolution is shown to be <3 μW/√Hz, with a long-term stability <4 μW/hour. The performance of the instrument is demonstrated via a set of experiments involving H2 absorption on Pd nanoparticles at various pressures and temperatures. For this specific reaction, we obtained a mass balance resolution of 0.1 μmol/√Hz. Results from these experiments are in good agreement with past studies establishing the feasibility of performing high resolution calorimetry on milligram scale nanomaterials, which can be employed in future studies probing catalysis, phase transformations, and thermochemical energy storage.
