Surface segregation in a polycrystalline Pd70Cu30 alloy hydrogen purification membrane
X-ray photoelectron spectroscopy (XPS) and low energy ion scattering spectroscopy (LEISS) have been used to study the effects of various surface preparations and thermal treatments on the composition of the near-surface region ( 7 atomic layers) and the topmost atomic layer of a polycrystalline Pd70Cu30 alloy. Palladium enrichment (relative to the bulk composition) is observed in the XPS-access...
متن کاملCFD simulation for segregation behavior of a ternary mixture in a bubbling fluidized bed: effect of solid wall boundary condition
Abstract The effect of the solid–wall boundary condition on the segregation behavior of a sand ternary mixture differing in size but having the same proportion has been investigated in a gas–solid bubbling fluidized bed. A multi-fluid computational fluid dynamics model incorporating the kinetic theory of granular flow has been used. The mass fraction profiles of the different-sized partic...

متن کاملThe effect of adsorbed sulfur on surface segregation in a polycrystalline Pd70Cu30 alloy
Surface segregation in alloys can be influenced by the presence of adsorbed species. In this work, the effect of adsorbed sulfur on surface segregation in a Pd70Cu30 alloy was studied for sulfur coverages from zero through saturation and for temperatures from 400 to 1000 K. X-ray photoemission spectroscopy (XPS) was used to determine the alloy composition in the near-surface region ( 7 atomic l...
متن کاملSegregation patterns of an equidensity TiO2 ternary mixture in a conical fluidized bed: CFD and experimental study
In this study, an Eulerian-Eulerian multi-fluid model (MFM) was used to simulate the segregation pattern of a conical fluidized bed containing ternary mixtures of equidensity TiO2 particles. Experimental 'freeze–sieving' method was employed to determine the axial mass fraction profiles of the different-sized particles, and validate the simulation results. The profiles of mass fraction for larg...
