Molecular Rotors for In Situ Viscosity Mapping during Evaporation of Confined Fluid Mixtures
Florence Gibouin, Dharshana Nalatamby, Pierre Lidon +1
Numerous formulation processes of materials involve a drying step, during which evaporation of a solvent from a multi-component liquid mixture, often confined in a thin film or in…
Molecular rotors for in situ local viscosity mapping in microfluidic chips
Dharshana Nalatamby, Florence Gibouin, Javier Ordoñez-Hernández +5
In numerous industrial processes involving fluids, viscosity is a determinant factor for reaction rates, flows, drying, mixing, etc. Its importance is even more determinant for phe…
Acoustic monitoring of the gelation of a colloidal suspension
Nicolas Bélicard, Marc Junior Niémet-Mabiala, Jean-Noël Tourvieille +1
Because they are sensitive to mechanical properties of materials and can propagate even in opaque systems, acoustic waves provides us with a powerful characterization tool in numer…
Mechanics and structure of carbon black gels under high-power ultrasound
Noémie Dagès, Pierre Lidon, Guillaume Jung +3
Colloidal gels made of carbon black particles dispersed in light mineral oil are "rheo-acoustic" materials, i.e., their mechanical and structural properties can be tuned using high…
Rheo-acoustic gels: Tuning mechanical and flow properties of colloidal gels with ultrasonic vibrations
Thomas Gibaud, Noémie Dagès, Pierre Lidon +7
Colloidal gels, where nanoscale particles aggregate into an elastic yet fragile network, are at the heart of materials that combine specific optical, electrical and mechanical prop…
Non-isothermal effects on water potential measurement in a simple geometry
Pierre Lidon, Etienne Perrot, Abraham D. Stroock
In this paper, we investigate quantitatively the coupling between gradients of temperature and of chemical or water potential under steady state conditions in the vapor phase. This…
A mesoscale study of creep in a microgel using the acoustic radiation force
Pierre Lidon, Louis Villa, Sébastien Manneville
We study the motion of a sphere of diameter 330 m embedded in a Carbopol microgel under the effect of the acoustic radiation pressure exerted by a focused ultrasonic field. The…
Enhanced oxygen solubility in metastable water under tension
Pierre Lidon, Sierra C. Marker, Justin J. Wilson +3
Despite its relevance in numerous natural and industrial processes, the solubility of molecular oxygen has never been directly measured in capillary condensed liquid water. In this…
Measurement of the acoustic radiation force on a sphere embedded in a soft solid
Pierre Lidon, Louis Villa, Nicolas Taberlet +1
The acoustic radiation force exerted on a small sphere located at the focus of an ultrasonic beam is measured in a soft gel. It is proved to evolve quadratically with the local amp…
Power-law creep and residual stresses in a carbopol microgel
Pierre Lidon, Louis Villa, Sebastien Manneville
We report on the interplay between creep and residual stresses in a carbopol microgel. When a constant shear stress is applied below the yield stress , the strain i…
Lecture notes on surface tension
Pierre Lidon
Lecture notes in french of the lecture on surface tension given in 2015 and 2016 at the preparation to "Agrégation de physique" in the Ecole Normale Supérieure de Lyon
Grains unchained: local fluidization of a granular packing by focused ultrasound
Pierre Lidon, Nicolas Taberlet, Sebastien Manneville
We report experimental results on the dynamics of a granular packing submitted to high-intensity focused ultrasound. Acoustic radiation pressure is shown to remotely induce local r…
