Study on the Cloud Point Extraction of Gd(III) with 8-Hydroxyquinoline

The extraction of gadolinium was studied using Cloud Point Extraction (CPE) with 8-hydroxyquinoline (8-HQ) as a chelating agent. The structure of the extracted Gd3+ complex with 8-HQ in the micelle of Triton X114 was determined using log-log analysis of the extraction data. A ratio of 8-HQ to Gd3+ of 3:1 was found. The CPE results were compared with those obtained by classical liquid-liquid extraction with chloroform as solvent. The parameters of the extraction process in both media were determined and compared. A quantitative extraction of Gd3+ at pH 5.5 was obtained by CPE using a 8-HQ/Gd3+ ratio of 10 although a 8-HQ/Gd3+ ratio of 500 was necessary for solvent extraction using chloroform as solvent, illustrating an increase of the mass action of extractants when using CPE instead of solvent extraction. Under those conditions, a higher extraction constant was determined for CPE compared with solvent extraction even if the formation of adducts in the CPE system could not be checked experimentally.

Hydrogen triggered exothermal reaction in uranium metal

An exothermal reaction has been observed when submitting metallic uranium to the combined action of a magnetic field and an electrical current. The set-up used to study the phenomenon is described and results are given. A tentative explanation is given, based on the possible existence of a still hypothetical proton/electron resonance.

Experimental Observation of Nuclear Reactions in Palladium and Uranium - Possible Explanation by Hydrex Mode

Experiments with uranium are presented that show a highly exothermal reaction, which can only be of nuclear origin. One striking point of these results is that they clearly show that what is being observed is not some kind of fusion reaction of the deuterium present (only exceedingly small amounts of it are present). This is a strong indication that hydrogen can trigger nuclear reactions that seem to involve the nuclei of the lattice (which would yield a fission-like pattern of products). Confronted with a situation where some experiments in the field yield a fusion-like pattern of products (CF experiments) and others a fissionlike one (LENR experiments), one can reasonably wonder whether one is not observing two aspects of the same phenomenon. Thus, it is proposed to describe CF and LENR reactions as essentially the same phenomenon based on the possible existence of a still hypothetical proton/electron resonance, which would catalyze fissionlike reactions with a neutron sink. Finally, a series of experiments is proposed to assess this hypothesis.

Exothermic reaction induced by high density current in metals - Possible nuclear origin

Since 1989, many experimenters worked on low-energy nuclear reactions (LENR). They face both an experimental and a theoretical dilemma: how to design simple and convincing experiments in a complex system and if the phenomenon has a nuclear origin, why do they observe no radiation. A rather simple water mass flow calorimeter was designed to study this phenomenon under different experimental conditions. First results indicate that a high-density current induced an exothermic reaction in a hydrogen processed palladium wire. A working hypothesis is presented to solve the theoretical dilemma. This working hypothesis is based on the possible existence of a still hypothetical proton/electron resonance. We underline that a working hypothesis is not a theory presented to explain the phenomenon; this is just a conceptual scheme to drive the authors to build experiments.
