ANOMALOUSLY ENHANCED D(d,p)T REACTION IN Pd AND PdO OBSERVED AT VERY LOW BOMBARDING ENERGIES
نویسندگان
چکیده
Yields of protons emitted in the D + D reaction in Pd and PdO thick targets were measured for bombarding energies between 2.5 and 10 keV. The obtained yields were compared with those predicted by using the parameterization of cross sections at higher energies. It was found that both of the yields for Pd and PdO are surprisingly larger than the prediction. The bombarding energy dependence of the yields are well described with screening potential parameters; Ue = 250 eV for Pd and 600 eV for PdO. The significance of a simple extrapolation of the observed enhancement is discussed.

Deuterium Gas Charging Experiments with Pd Powders for Excess Heat Evolution ( II ) Discussions on Experimental Results and Underlying Physics
Experimental results obtained for Pd/PdO/ZrO2 nano-composite samples are summarized and the underlying physics is discussed. Arata-Zhang’s May 2008 excess heat result was replicated quantitatively. Using Pd/PdO/ZrO2 powders (produced by Santoku Co., Kobe Japan), we obtained: 1) D-gas charge in the first phase (zero pressure interval) gave 20~90% excess heat than H-gas charge. 2) In the second p...
متن کاملRedox functionality mediated by adsorbed oxygen on a Pd oxide film over a Pd(100) thin structure: a first-principles study.
Stable oxygen sites on a PdO film over a Pd(100) thin structure with a [Formula: see text] surface unit cell are determined using the first-principles electronic structure calculations with the generalized gradient approximation. The adsorbed monatomic oxygen goes to a site bridging two twofold-coordinated Pd atoms or to a site bridging a twofold-coordinated Pd atom and a fourfold-coordinated P...
متن کاملLow Energy Nuclear Fusion Reactions in Solids
The DD fusion reactions in various materials have been studied, and enhancements in the rate of the D(d,p)T fusion reaction over the Gamow function were clearly seen in the materials. Of particular interest is the fact that the reaction rate of the D+D reactions at 2.5 keV in PdO is 60 times (and in Pd 10 times) larger than in Ti, and the deduced screening energy amounts to 600 eV (300 eV). Fur...
متن کاملAtomically Dispersed Pd–O Species on CeO2(111) as Highly Active Sites for Low-Temperature CO Oxidation
Ceria-supported Pd is a promising heterogeneous catalyst for CO oxidation relevant to environmental cleanup reactions. Pd loaded onto a nanorod form of ceria exposing predominantly (111) facets is already active at 50 °C. Here we report a combination of CO-FTIR spectroscopy and theoretical calculations that allows assigning different forms of Pd on the CeO2(111) surface during reaction conditio...

Heterostructures play an important role not only in the manufacture of semiconductor devices, but also in the field of catalysis. Herein, we report the synthesis of PdO/TiO2 and Pd/TiO2 heterostructured nanobelts by means of a simple co-precipitation method, followed by a reduction process using surface-modified TiO2 nanobelts as templates. The as-obtained heterostructures were characterized by...
