Nanorheology: An investigation of the boundary condition at hydrophobic and hydrophilic interfaces
Abstract:It has been shown that the flow of a simple liquid over a solid surface can violate the so-called no-slip boundary condition. We investigate the flow of polar liquids, water and glycerol, onExpand

Hydrodynamic interaction between a spherical particle and an elastic surface: a gentle probe for soft thin Films.
We study the hydrodynamic interaction between a sphere and an elastic surface at a nanoscale with a dynamic surface force apparatus. We show that the interplay between viscous forces and elasticExpand

Physics of humid granular media
Abstract A very small amount of liquid added or condensed from a vapor in a granular heap can induce dramatic changes of its static properties. In this paper we review recent advances in humidExpand

A new surface forces apparatus for nanorheology
We present an original surface forces apparatus which enables us to measure the interaction forces between any solid surfaces such as, e.g., metallic surfaces, opaque surfaces, or rough surfaces. TheExpand

Landau-Levich menisci.
As shown by Landau, Levich and Derjaguin, a plate withdrawn out of a wetting bath at low capillary numbers deforms the very top of the liquid reservoir. At this place, a dynamic meniscus forms, whoseExpand

Adhesion between weakly rough beads.
Cohesion effects are of prime importance in powders and granular media, and they are strongly affected by the roughness of the grain surface. We report measurements of the adhesion force betweenExpand

Fracture of a viscous liquid.
When a viscous liquid hits a pool of liquid of the same nature, the impact region is hollowed by the shock. Its bottom becomes extremely sharp if increasing the impact velocity, and we report thatExpand

Capillary bridge formation and breakage: a test to characterize antiadhesive surfaces.
In order to characterize very weak adhesive surfaces, we have developed a quantitative test inspired by the Johnson, Kendall, and Roberts adhesion test for soft adhesives, which relies on theExpand

Contact angle and contact angle hysteresis measurements using the capillary bridge technique.
A new experimental technique is proposed to easily measure both advancing and receding contact angles of a liquid on a solid surface, with unprecedented accuracy. The technique is based on theExpand

Plate coating: influence of concentrated surfactants on the film thickness.
We present a large range of experimental data concerning the influence of surfactants on the well-known Landau-Levich-Derjaguin experiment where a liquid film is generated by pulling a plate out of aExpand
