Effects of Confinement and Shear on the Properties of Thin Films of Thermotropic Liquid Crystal

TL;DR: In this article, the surface forces apparatus technique was used to measure the normal forces, thin film viscosity, and lateral (frictional) forces between two surfaces interacting across 4'n-octyl-4'cyanobiphenyl (8CB), to determine the effects of confinement (film thickness) and shear (sliding velocity) on the ordering of the smectic-A and the nematic phases.

Direct measurement of single and ensemble average particle-surface potential energy profiles.

TL;DR: The capabilities of the ensemble averaging technique are demonstrated to provide unique measurements of particle-surface interactions in metastable systems by selecting only height excursions of levitated particles when calculating potentials.

Pair interaction energy between deformable drops and bubbles

TL;DR: In this article, the potential energy of interaction between two deformed particles, having the shape of spherical segments and separated by a planar film, is considered, and an exact expression for the van der Waals interaction energy between such particles of arbitrary size and deformation is derived by using the microscopic approach of Hamaker.

Direct Measurements of Interactions between Hydrophobically Anchored Strongly Charged Polyelectrolyte Brushes

TL;DR: In this paper, the authors investigated the nature and the range of interactions between negatively charged polyelectrolyte-coated surfaces as a function of salt concentration using the surface forces apparatus.

New Mechanism of Cavitation Damage

TL;DR: In this article, it was shown that large impact pressures can develop when a vapor cavity collapses in a liquid, and these pressures are the underlying cause of cavitation damage of surfaces.
