Asymmetric bistability of chiral particle orientation in viscous shear flows
Andreas Zöttl, Francesca Tesser, Daiki Matsunaga +3
The migration of helical particles in viscous shear flows plays a crucial role in chiral particle sorting. Attaching a non-chiral head to a helical particle leads to a rheotactic t…
Active boundary layers
Jérôme Hardoüin, Claire Doré, Justine Laurent +3
The role of boundary layers in conventional liquid crystals is commonly subsumed in their anchoring on confining walls. In the classical view, anchoring enslaves the orientational…
Reconfigurable Flows and Defect Landscape of Confined Active Nematics
Jérôme Hardoüin, Rian Hughes, Amin Doostmohammadi +5
Using novel micro-printing techniques, we develop a versatile experimental setup that allows us to study how lateral confinement tames the active flows and defect properties of the…
Capillary force on a tilted cylinder: AFM measurements
Sebastien Kosgodagan Acharige, Justine Laurent, Audrey Steinberger
We investigate the capillary force that applies on a tilted cylinder as a function of its dipping angle i, using a home-built tilting Atomic Force Microscope (AFM) with custom made…
AFM study of hydrodynamics in boundary layers around micro- and nanofibers
Julien Dupré de Baubigny, Michael Benzaquen, Caroline Mortagne +7
The description of hydrodynamic interactions between a particle and the surrounding liquid, down to the nanometer scale, is of primary importance since confined liquids are ubiquit…
Microrheology measurements with a hanging-fiber AFM probe
Clemence Devailly, Justine Laurent, Audrey Steinberger +2
A method to measure the viscosity of liquids at microscales is presented. It uses a thin glass fiber fixed on the tip of the cantilever of an extremely low noise Atomic Force Micro…
Functionalized AFM probes for force spectroscopy: eigenmodes shape and stiffness calibration through thermal noise measurements
Justine Laurent, Audrey Steinberger, Ludovic Bellon
The functionalization of an Atomic Force Microscope (AFM) cantilever with a colloidal bead is a widely used technique when the geometry between the probe and the sample must be con…
