Recent studies have identified the ‘subsurface’ oxygen on Pd(110) as a nucleation of an oxide phase. This species has been postulated as responsible for oscillations in the catalytic CO oxidation on this surface. We have investigated the kinetics

The electrochemical deposition and stripping of mercury on gold surfaces was investigated to assess whether gold electrodes would return to mercury-free states after stripping analyses. X-ray photoelectron spectroscopy studies demonstrate the presenc

Thin Pt TiO 2−x sensing films are characterized with X-ray photoelectron spectroscopy (XPS) and ultra-violet photoelectron spectroscopy (UPS) to investigate the mechanism of resistance decreases measured in situ on exposure to hydrogen and propylen

The role of chemisorbed oxygen in further sensitizing thin Pt TiO 2−x sensing films to H2 and C3H6 exposure is discussed. The interaction of these oxygen sensitized films with H2 and C3H6 is investigated with resistance measurements, X-ray photoele

Environmental factors have a strong effect on the elevated-temperature failure behavior of nickel-based alloys. It has been proposed that this effect is due to the reactions of oxygen with carbon in the interior of creep cavities. Such reactions can

We propose a new mechanism for surface systems: dissociation-stimulated desorption . Evidence for this effect is provided by results from a detailed temperature programmed desorption (TPD) study of submonolayer coverages of CO on clean Fe(100). Our t

Adsorbed oxygen at room temperatures exists on Pd(110) in two states, a surface state ( β 2 ) and a more weakly bound state ( β 1 ), previously designated as “subsurface” oxygen. The “subsurface” state was postulated as responsible for the

These initial results strongly suggest that the enrichment and segregation of niobium at grain boundary surfaces played an important role in the environmental enhancement of creep crack growth in the Inconel 718. The precise mechanism, however, still

The surface composition of an Inconel 718 (100) single crystal was investigated by X-ray photoelectron spectroscopy over the temperature range 300 to 1000 K in ultra-high vacuum (UHV). The surface composition of an ion etched surface closely resemble
