Thermal Lensing Effects in Two-Photon Light-Sheet Microscopy
Antoine Hubert, Hugo Trentesaux, Thomas Pujol +2
In light-sheet fluorescence microscopy (LSFM), the axial resolution is governed by the illumination beam profile, motivating the development of advanced beam-shaping techniques to…
Probing locally the onset of slippage at a model multi-contact interface
V. Romero, E. Wandersman, G. Debrégeas +1
We report on the multi-contact frictional dynamics of model elastomer surfaces rubbed against bare glass slides. The surfaces consist of layers patterned with thousands spherical c…
Texture-induced modulations of friction force: the fingerprint effect
E. Wandersman, R. Candelier, G. Debregeas +1
Dry solid friction is often accompanied by force modulations originating from stick-slip instabilities. Here a distinct, quasi-static mechanism is evidenced leading to quasi-period…
Effect of fingerprints orientation on skin vibrations during tactile exploration of textured surfaces
Alexis Prevost, Julien Scheibert, Georges Debrégeas
In humans, the tactile perception of fine textures is mediated by skin vibrations when scanning the surface with the fingertip. These vibrations are encoded by specific mechanorece…
X-ray observation of micro-failures in granular piles approaching an avalanche
Alexandre Kabla, Georges Debregeas, Jean-Marc Di Meglio +1
An X-ray imaging technique is used to probe the stability of 3-dimensional granular packs in a slowly rotating drum. Well before the surface reaches the avalanche angle, we observe…
Contact dynamics in a gently vibrated granular pile
Alexandre Kabla, Georges Debregeas
We use multi-speckle diffusive wave spectroscopy (MSDWS) to probe the micron-scale dynamics of a granular pile submitted to discrete gentle taps. The typical time-scale between pla…
