X-ray Reflectivity Studies of Atomic-level Surface-segregation in a Liquid Eutectic Alloy of AuSn
Venkatachalapathy S. K. Balagurusamy, Reinhard Streitel, Oleg G. Shpyrko +3
X-ray reflectivity studies reveal atomic-level surface-segregation at the free surface of the eutectic Au71Sn29 liquid alloy. The surface-segregation extends up to three layers, in…
Crystalline Surface Phases of the Liquid Au-Si Eutectic Alloy
Oleg G. Shpyrko, Reinhard Streitel, Venkatachalapathy S. K. Balagurusamy +6
A two dimensional crystalline layer is found at the surface of the liquid eutectic AuSi alloy above its melting point C. Underlying this crystalline…
Capillary Filling of Anodized Alumina Nanopore Arrays
K. J. Alvine, O. G. Shpyrko, P. S. Pershan +2
The filling behavior of a room temperature solvent, perfluoromethylcyclohexane, in approximately 20 nm nanoporous alumina membranes was investigated in situ with small angle x-ray…
Surface Crystallization in a Liquid AuSi Alloy
Oleg G. Shpyrko, Reinhard Streitel, V. S. K. Balagurusamy +6
X-ray measurements reveal a crystalline monolayer at the surface of the eutectic liquid Au_{82}Si_{18}, at temperatures above the alloy's melting point. Surface-induced atomic laye…
Solvent Mediated Assembly of Nanoparticles Confined in Mesoporous Alumina
Kyle J. Alvine, Diego Pontoni, Oleg G. Shpyrko +7
The controlled self-assembly of thiol stabilized gold nanocrystals in a mediating solvent and confined within mesoporous alumina was probed in situ with small angle x-ray scatterin…
Atomic-scale surface demixing in a eutectic liquid BiSn alloy
Oleg G. Shpyrko, Alexei Yu. Grigoriev, Reinhard Streitel +6
Resonant x-ray reflectivity of the surface of the liquid phase of the BiSn eutectic alloy reveals atomic-scale demixing extending over three near-surface atomic layer…
