Electrochemical Loading of Hydrogen and Deuterium Into Palladium and Palladium-Boron Alloys
Excess power production and other anomalous effects have been observed during the electrolysis of heavy water using palladium and palladium-boron alloys as the cathode materials. This study focused on hydrogen and deuterium loading into palladium and palladium-boron alloys. Improved calorimetry provided for the detection of the exothermic heat of absorption of deuterium into palladium and palla...
متن کاملIn Situ Accelerator Analyses of Palladium Complex under Deuterium Permeation
Preliminary results of experiments on D2 gas permeation using a system [vacuum/CaO/Sr/PdD x/D2] have shown some evidence of nuclear transmutation from Sr to Mo. The system is a little simpler than that used by Iwamura et al., and has a reversed gas flow direction. The diagnostic method used to identify the elements was conventional XPS, giving the areal densities of 4.21014 cm-2 (Sr) and 3.31...
متن کاملGas loading of deuterium in palladium at low temperature
The experimental technique presented in this article is aimed at measuring the absorption of hydrogen or deuterium gas in a thin palladium sample while the system is at low temperature. A result for deuterium is described, consisting in the measurement of the equilibrium loading ratio X (called also D/Pd ratio, atomic), as a function of pressure, on a palladium film 3.6 μm-thick at 150 K. Value...
متن کاملInteraction of Hydrogen and Deuterium with Dislocations in Palladium as Observed by Small Angle Neutron Scattering
Small angle neutron scattering (SANS) measurements on Pd samples containing dislocations with a density of a few 10 cm 2 reveal an additional intensity for a scattering vector of 0.02 Å 1 to 0.2 Å 1 after loading with hydrogen (H) or deuterium (D). The corresponding net cross section is inversely proportional to the scattering vector as expected for line type scattering objects with a superimpo...
متن کاملCharging-free electrochemical system for harvesting low-grade thermal energy.
Efficient and low-cost systems are needed to harvest the tremendous amount of energy stored in low-grade heat sources (<100 °C). Thermally regenerative electrochemical cycle (TREC) is an attractive approach which uses the temperature dependence of electrochemical cell voltage to construct a thermodynamic cycle for direct heat-to-electricity conversion. By varying temperature, an electrochemical...
