The complete phase diagram of oxygen atoms chemisorbed on Ni(111) has been determined. The two-dimensional system is realized for oxygen coverages of 0.5 monolayers and temperatures 500 K. At higher coverages and temperatures oxygen is incorporated into the bulk. The structure of the oxygen overlayer was determined by low-energy electron diffraction and the coverage was monitored by Auger ...

Phase diagram of oxygen. Phase Diagram of Liquid Ozone‐Oxygen System: The Journal ... Vapor pressure composition data for liquid ozone‐oxygen mixtures were obtained at —195.5°, —183°, and —180°C. The vapor pressure isotherms were used to construct the boiling point‐composition line at one‐atmos pressure. The vapor pressure of pure liquid ozone defines an upper limit for the partial pressure of ozone in the vapor in equilibrium with boiling liquid. Phase diagram of oxygen on Ni(100) - ScienceDirect This would mean that oxygen atoms free to wander across the surface, such as those in a disordered lattice gas, would have a much enhanced L78 D.E. Taylor, R.L Park / Phase diagram of oxygen on Ni(lOO) probability of going into the bulk as compared to oxygen atoms locked into position, such as those in large ordered p(2 X 2) or c(2 X 2) islands. Oxygen - Thermophysical properties Oxygen is a gas at standard conditions. However, at low temperature and/or high pressures the gas becomes a liquid or a solid. The oxygen phase diagram shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the oxygen boiling point with changes in pressure. Phase diagram for the interaction of oxygen with SiC ... We report on experimental studies of the interactions of oxygen with the 4H- and 6H-SiC surfaces at high temperatures. It is observed that these interactions lead to the growth of passivating SiO 2 layers at high O 2 pressures, etching of the surfaces at lower pressures, and enhancements of the surface segregation of carbon at still lower ...

Phase diagram of oxygen on Ni(100) — Northwestern Scholars We have studied the coverage-temperature phase diagram of chemisorbed oxygen on Ni(100) with LEED and AES. We find that the oxygen p(2 × 2) structure undergoes a nearly reversible order- disorder phase transition for coverages between 0.15 and 0.30 monolayer (T c ≈ 560 K for θ = 0.25). For these coverages, it is also found that the chemisorbed oxygen begins dissolving into the bulk nickel ... Phys. Rev. B 70, 045420 (2004) - Phase diagram of oxygen ... A complete phase diagram of oxygen atoms adsorbed on a Pt (111) surface with oxygen coverages below half a monolayer has been computed and compared with the surface phase diagrams of related systems. Effective interaction parameters of a lattice model for the triangular lattice of the fcc sites of the Pt (111) surface were determined from first-principles computations.

Phase Diagrams Sketch a phase diagram for oxygen and label all points of interest. We spare you my horrid art work and give the phase diagram as drawn in the intructor's manual: There is a little guesswork to some parts of a diagram like this, especially the smooth curve between the liquid and gas phases and between the solid and gas phases. Reactions of Oxygen with the Platinum Metals | Johnson ... Phase diagram for iridium in equilibrium with one atmosphere of oxygen. The hatching along the horizontal axis represents solid IrO 2, and the full black line iridium metal, trhieh is the only solid phase in equilibrium above 1120°C. New phase diagram of oxygen at high pressures and ... In situ high P-T Raman measurements and optical observations of solid and fluid oxygen up to 1250 K between 8 and 25 GPa reveal the existence of a new molecular phase eta and strikingly unusual behavior of the melting curve. Three triple points were also identified in the P-T domain of the new phase …

Characterization of the phase diagram of the yttrium ... The principle of equilibrium potential-pH diagrams for two-dimensional species adsorbed on metals is applied to the case of sulfur and oxygen adsorbed on nickel in water. Standard Gibbs energies of formation for sulfur and oxygen adsorbed on nickel are calculated from literature thermodynamic data for chemisorption from the gas phase.

Electronic phase diagram of oxygen-deficient SmNiO3−δ ... The electronic phase diagram of the strained SmNiO 3−δ films is comparable to those reported for Ca 2+ or Co 3+ doped SmNiO 3 [12, 22], suggesting that the oxygen deficiency induced structural variation also strongly suppresses the antiferromagnetic correlations as well as the carrier injection and different spin state.
