Diffusiophoretic migration of colloidal particles in sucrose gradients
Antoine Monier, Brielle Byerley, Julien Renaudeau +3
Diffusiophoresis (DP) refers to the migration of particles driven by a solute concentration gradient in a liquid. Observations in the case of molecular neutral solutes are rather s…
Transient osmotic flows in a microfluidic channel: measurements of solute permeability and reflection coefficients of hydrogel membranes
Julien Renaudeau, Pierre Lidon, Jean-Baptiste Salmon
We first highlight theoretically a microfluidic configuration that allows to measure two fundamental parameters describing mass transport through a membrane: the solute permeabilit…
Pervaporation-driven electrokinetic energy harvesting using poly(dimethylsiloxane) microfluidic chips
Hrishikesh Pingulkar, Cédric Ayela, Jean-Baptiste Salmon
Electrokinetic energy harvesting from evaporation-driven flows in porous materials has recently been the subject of numerous studies, particularly with the development of nanomater…
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…
Shear-thickening in presence of adhesive contact forces: the singularity of cornstarch
Anais Gauthier, Guillaume Ovarlez, Annie Colin
A number of dense particle suspensions experience a dramatic increase in viscosity with the shear stress, up to a solid-like response. This shear-thickening process is understood a…
Microfluidic osmotic compression of a charge-stabilized colloidal dispersion: Equation of state and collective diffusion coefficient
Camille Keita, Yannick Hallez, Jean-Baptiste Salmon
We show, using a model coupling mass transport and liquid theory calculations for a charge-stabilized colloidal dispersion, that diffusion significantly limits measurement times of…
Collective diffusion coefficient of a charged colloidal dispersion: interferometric measurements in a drying drop
Benjamin Sobac, Sam Dehaeck, Anne Bouchaudy +1
In the present work, we use Mach-Zehnder interferometry to thoroughly investigate the drying dynamics of a 2D confined drop of a charged colloidal dispersion. This technique makes…
X Radiography of Viscous Resuspension
Brice Saint-Michel, Sébastien Manneville, Steven Meeker +2
We use X-ray imaging to study viscous resuspension. In a Taylor-Couette geometry, we shear an initially settled layer of spherical glass particles immersed in a Newtonian fluid and…
Humidity-insensitive water evaporation from molecular complex fluids
Jean-Baptiste Salmon, Frédéric Doumenc, Béatrice Guerrier
We investigated theoretically water evaporation from concentrated supramolecular mixtures, such as solutions of polymers or amphiphilic molecules, using numerical resolutions of a…
Simultaneous concentration and velocity maps in particle suspensions under shear from rheo-ultrasonic imaging
Brice Saint-Michel, Hugues Bodiguel, Steven Meeker +1
We extend a previously developed ultrafast ultrasonic technique [Gallot et al., Rev. Sci. Instrum. 84, 045107 (2013)] to concentration field measurements in non-Brownian particle s…
Droplet microfluidics to prepare magnetic polymer vesicles and to confine the heat in magnetic hyperthermia
Damien Habault, Alexandre Déry, Jacques Leng +3
In this work, we present two types of microfluidic chips involving magnetic nanoparticles dispersed in cyclohexane with oleic acid. In the first case, the hydrophobically coated na…
Dynamics and rheology under continuous shear flow studied by X-ray photon correlation spectroscopy
Andrei Fluerasu, Pawel Kwasniewski, Chiara Caronna +3
X-ray Photon Correlation Spectroscopy (XPCS) has emerged as a unique technique allowing the measurement of dynamics in materials on mesoscopic lengthscales. In particular, applicat…
Wall slip, shear banding, and instability in the flow of a triblock copolymer micellar solution
S. Manneville, A. Colin, G. Waton +1
The shear flow of a triblock copolymer micellar solution (PEO--PPO--PEO Pluronic P84 in brine) is investigated using simultaneous rheological and velocity profile measurements in t…
A kinetic theory of plastic flow in soft glassy materials
Lyderic Bocquet, Annie Colin, Armand Ajdari
A kinetic model for the elasto-plastic dynamics of a flowing jammed material is proposed, which takes the form of a non-local -- Boltzmann-like -- kinetic equation for the stress d…
A microfluidic device based on droplet storage for screening solubility diagrams
P. Laval, N. Lisai, J. -B. Salmon +1
This work describes a new microfluidic device developed for rapid screening of solubility diagrams. In several parallel channels, hundreds of nanoliter-volume droplets of a given s…
A microfluidic device for investigating crystal nucleation kinetics
Philippe Laval, Jean-Baptiste Salmon, Mathieu Joanicot
We have developed an original setup using microfluidic tools allowing one to produce continuously monodisperse microreactors ( nL), and to control their temperatures a…
Microfluidic Exploration of the Phase Diagram of a Surfactant/Water Binary System
Jacques Leng, Mathieu Joanicot, Armand Ajdari
We investigate the behaviour of a binary surfactant solution (AOT/water) as it is progressively concentrated in microfluidic evaporators. We observe in time a succession of phase t…
Yielding and flow in adhesive and non-adhesive concentrated emulsions
L. Becu, S. Manneville, A. Colin
The nonlinear rheological response of soft glassy materials is addressed experimentally by focusing on concentrated emulsions where interdroplet attraction is tuned through varying…
Micro-evaporators for kinetic exploration of phase diagrams
Jacques Leng, Barbara Lonetti, Patrick Tabeling +2
We use pervaporation-based microfluidic devices to concentrate species in aqueous solutions with spatial and temporal control of the process. Using experiments and modelling, we qu…
