What controls the thickness of wetting layers near bulk criticality?

In situ Determination of Surface Tension-to-Shear Viscosity Ratio for Quasiliquid Layers on Ice Crystal Surfaces.

We have experimentally determined the surface tension-to-shear viscosity ratio (the so-called characteristic velocity) of quasiliquid layers (QLLs) on ice crystal surfaces from their wetting dynamics. Using an advanced optical microscope, whose resolution reaches the molecular level in the height direction, we directly observed the coalescent process of QLLs and followed the relaxation modes of...

Effect of criticality on wetting layers.

Order and Disorder Phenomena at Surfaces of Binary Alloys

We present recent Monte Carlo results on surfaces of bcc-structured binary alloys which undergo an order-disorder phase transformation in the bulk. In particular, we discuss surface order and surface induced disorder at the bulk transition between the ordered (DO3) phase and the disordered (A2) phase. An intricate interplay between different ordering and segregation phenomena leads to a complex...

A new approach for fabrication of bulk MMCs using Accumulative Channel-die Compression Bonding (ACCB)

A new severe plastic deformation (SPD) based technique entitled Accumulative channel-die compression bonding (ACCB) is proposed for the fabrication of high strength multi-layered Al/Cu composites for the first time. In order to primarily demonstrate the capabilities of ACCB in the fabrication of metal matrix composites (MMCs), AA 1050 and pure Cu strips were processed. The primary Al/Cu sandwic...

Thermal fluctuation forces and wetting layers in colloid-polymer mixtures: derivation of an interface potential.

We discuss wetting layers in phase-separated colloid-polymer mixtures adsorbed at a vertical wall, observed in recent laser scanning confocal microscopy experiments. Matching of colloid and solvent dielectric properties renders van der Waals forces negligible and provides a system governed by short-range forces and thermal fluctuations on which the subtle predictions of renormalization group (R...
