    Advancements of intense terahertz field focusing on metallic nanoarchitectures for monitoring hidden interatomic gas-matter interactions


    "With the advancements of nanotechnology, innovative photonic designs coupled with

    the functional materials provide a unique way to acquire, share, and respond effectively

    to information. We found that the simple deposition of a 30 nm-thick palladium

    nanofilm on a terahertz metasurface chip with a 14 nm-wide effective nanogap of

    asymmetric materials and geometries allows the tracking of both interatomic and

    interfacial gas–matter interactions, including gas adsorption, hydrogenation (or

    dehydrogenation), metal phase changes, and unique water-forming reactions.

    Combinatorial analyses by simulation and experimental measurements demonstrated our

    distinct nanostructures, which led to significant light-matter interactions and

    corresponding terahertz absorption in a real-time, highly repeatable, and reliable manner.

    The complex lattice dynamics and intrinsic properties of metals influenced by hydrogen

    gas exposure were also thoroughly examined using systematically controlled ternary gas

    mixture devices that mimic normal temperature and pressure."

    detectors, utilized in experiments and interrogated for tracks post-experiment, produced positive results that our team attributes to thousands

    of individual particle impacts in dense clusters, likely with energies between 0.1 and 20 MeV. Similar nuclear particle, thermal, and RF results

    have separately appeared in prior reports, but in this work, all three categories of anomalous behavior are reported. Results indicate that the

    Electron screening in the 2H(19F,p)20F reaction


    Abstract. The dependence of electron screening potential on the position of the target nucleus

    in host-material lattice was investigated by measuring the rate of the 2H(19F,p)20F reaction in

    zirconium, titanium and palladium targets containing deuterium. Very different values of the

    screening potential were measured, thus showing the link with the valence electron densities

    around deuterium nuclei.

    Chiral catalysis of nuclear fusion in molecules


    At low energies, nuclear fusion is strongly affected by electron screening of the Coulomb repulsion

    among the fusing nuclei. It may thus be possible to catalyze nuclear fusion in molecules (i.e.,

    to fuse specific nuclei in situ) through quantum control of electron wave functions in intense laser

    fields. The circularly polarized (chiral) laser field can effectively squeeze the electron wave functions,

    greatly enhancing the screening in the spatial region relevant for the fusion process. We estimate

    the corresponding fusion probabilities, and find that the proposed chiral catalysis of nuclear fusion

    in molecules may be observable, potentially with important practical applications.

    The wording below is an initial machine translation of the original publication.


    "FIG. 1 The invention relates to methods for producing x-ray radiation, based on the occurrence of electron emission in case of contact failure between the bodies. A known method for producing x-ray radiation in the event of adhesive contact is broken, which consists in continuously rolling a flat body under a roller under atmospheric conditions 1. The disadvantage of this method is that x-ray radiation is observed only directly in the contact zone, i.e. It is impossible to obtain a stable and directed radiation flux. Closest to the invention is a method for producing x-ray radiation, which consists in breaking the adhesive contact between two elements when they are relatively moved in vacuum 2. A disadvantage of the known method, in which a roller and a sticky polymer film were used as contacting elements, is the impossibility of any noticeable regulation of the parameters of the received radiation, stabilization of these parameters. The purpose of the invention is the expansion of the regulation of the parameters of the received radiation. This goal is achieved by the fact that according to the method of obtaining x-ray radiation, which consists in breaking contact between the two elements when they are relatively moved in a vacuum, a plane dielectric or insulated metal body is used as one of the elements, and a roller coated with a fleecy material is used as the other element, the roller is rotated with a linear speed of its rubbing surface of 1 -10 m / s at a pressure of clamping to a flat body of 0.5-2.0 g / cm. In FIG. 1 shows a diagram of an apparatus for implementing a method for producing x-ray radiation" ....
