Hydrogen in metals has possible applications in various energy storage devices. For the palladium-deuterium system, excess power production and other anomalous effects have been reported. This study focused on hydrogen and deuterium insertion into palladium and deuterium insertion into various palladium-boron alloys. The condition of the metal surface is a major factor in the insertion of hydro...

The influence of the electronic structure and the lattice constant on hydrogen absorption in bulk Pd3M1 (M = Cd, Ag, Au, Pd, Cu, Ni, Pt, Pb, Sn, Fe, Rh, Ru) has been studied by density-functional calculations. We have assumed face-centred cubic structure for all the alloys, and hydrogen has been placed in the octahedral site surrounded by six Pd atoms. We have calculated the absorption energy o...

This study evaluated the effects of metal primers on the bonding of adhesive resin to four pure metals (Au, Pd, Ag, Cu) and two noble alloys for porcelain fusing (high-gold and high-palladium content alloys). Bonding surface was polished with 600-grit silicon carbide paper and primed with one of the three metal primers (V-Primer, Metaltite, and M.L. Primer). Bonded specimens were fabricated by ...

A number of palladium alloys have been loaded with deuterium or hydrogen under low energy plasma bombardment in a system that allows the continuous measurement of tritium. Long run times (up to 200 h) result in an integration of the tritium and this, coupled with the high intrinsic sensitivity of the system (~ 0.1nCi/l), enables the significance of the tritium measurement to be many sigma (>10)...

The isothermal age-hardening behaviour in the commercial dental gold alloys containing palladium was studied by means of resistometric, hardness, X-ray and electron microscopy. Drastic overageing occurred following prolonged ageing. The mechanism of the overageing was interpreted as a loss of coherency at the interfaces of the adjacent lamellae which consists of the equilibrium AuCu I ordered p...

The magnetic susceptibilities and electrical conductivities of cobalt, nickel and palladium and of their alloys with copper, silver and gold are discussed on the basis of the quantum theory of metals. It is shown that the number of electrons in the outermost s state must be about 0.6 per atom in the transition metals and one in the noble metals; certain magnetic properties of the alloys are exp...

The development of materials which contain the noble metals for use in high temperature strain gauges is reviewed, with particular emphasis being placed upon work done by the Institute of Precious Metals, in China. Three alloy systems displaying excellent resistance to oxidation and good overall properties when used in high temperature straingauges, are singled out for examination. These are pl...

Matrix assisted laser desorption ionization of a mixture of gold and palladium adducts of the protein lysozyme (Lyz) produces naked alloy clusters of the type Au24Pd(+) in the gas phase. While a lysozyme-Au adduct forms Au18(+), Au25(+), Au38(+) and Au102(+) ions in the gas phase, lysozyme-Pd alone does not form any analogous cluster. Addition of various transition metal ions (Ag(+), Pt(2+), Pd...
