(An) analysis of the hydrogen absorption process via palladium hybrid porous aluminum oxide to re-visit the cold fusion

다국어 초록 (Multilingual Abstract)

For decades, the term “nuclear fusion” has been familiar among scientists; for those who might be unfamiliar with the phrase “nuclear fusion,” it is a reaction involving at least two atomic nuclei fuse to produce a heavier core with the release of energy, which is the principal reactions that power the Sun and other Stars. Once the nuclear reaction is triggered, it will maintain the reaction itself until it runs out of atoms; however, the fusion reactions only happen at extremely high temperatures and pressure, making them exceptionally difficult to trigger in vitro and impossible to regulate the reaction. Then nearly thirty years ago, in 1989, two chemists Martin Fleischmann and Stanley Pons, while researching the electrochemistry phenomenon of Palladium (Pd) in heavy water, reported that their apparatus had produced an unnatural amount of excess heat of a magnitude they asserted would defy explanation in terms of nuclear processes. It can only be explained by applying the hypothesized nuclear reaction type, called “Cold Fusion.” It is demonstrated that the nuclear reaction would occur at or near the temperature room. However, despite the efforts of many other scientists who tried to replicate the experiment, many have failed; to date, no successful replication has been found. A few groups have begun to re-examine the Cold Fusion issue in recent years; many are actively involved in the controversial field of Low Energy Nuclear Reactions (LENR). LENR researchers are attempting to perform experiments that closely replicate the setup in the original Pons-Fleischmann experiment. We were motivated to write this thesis by the Nature publication released in 2019 that re-visited the cold fusion argument and called for action on the subject. We decided to re-visit cold fusion using a new approach based on our expertise in the materials field. This study adopted an alternate technique to produce chemical-free, evenly dispersed Palladium nanoparticles hybrid Conventional Porous Anodic Aluminum Oxide (Pd-NP/AAO) to attempt cold fusion using the nanomaterials. Pd-NP/AAO was used in this work to evaluate the hydrogen absorption and desorption characteristics of Hydrogen and the practicality of the proposed approach, among other things.
