Condensed Matter - Soft Condensed Matter - Abstract
We survey the linear viscoelasticity of a new type of transient network: bridged wormlike micelles, whose structure has been characterized recently [Ramos and Ligoure, (2007)]. This composite material is obtained by adding telechelic copolymers (water-soluble chains with hydrophobic stickers at each extremity) to a solution of entangled wormlike micelles (WM). For comparison, naked WM and WM decorated by amphiphilic copolymers are also investigated. While these latter systems exhibit almost a same single ideal Maxwell behavior, solutions of bridged WM can be described as two Maxwell fluids components blends, characterized by two markedly different characteristic times, t_fast and t_slow, and two elastic moduli, G_fast and G_slow, with G_fast >> G_slow. We show that the slow mode is related to the viscoelasticity of the transient network of entangled WM, and the fast mode to the network of telechelic active chains (i.e. chains that do not form loops but bridge two micelles). The dependence of the viscoelasticity with the surfactant concentration, phi, and the sticker-to-surfactant molar ratio, beta, is discussed. In particular, we show that G_fast is proportional to the number of active chains in the material, phi beta. Simple theoretical expectations allow then to evaluate the bridges/loops ratio for the telechelic polymers.

We investigate the flow properties of a two-dimensional aqueous foam submitted to a quasistatic shear in a Couette geometry. A strong localization of the flow (shear banding) at the edge of the moving wall is evidenced, characterized by an exponential decay of the average tangential velocity. Moreover, the analysis of the rapid velocity fluctuations reveals self-similar dynamical structures consisting of clusters of bubbles rolling as rigid bodies. To relate the instantaneous (elastic) and time-averaged (plastic) components of the strain, we develop a stochastic model where irreversible rearrangements are activated by local stress fluctuations originating from the rubbing of the wall. This model gives a complete description of our observations and is also consistent with data obtained on granular shear bands by other groups., Comment: 5 pages, 2 figures

- Abstract
Mixing fronts at the interface of opposing flows are compressed at a constant rate. The resulting exponential stretching of fluid elements leads to enhanced chemical gradients and biogeochemical processes. This process is similar as what occurs in the pore space of 3D chaotic flows. However, it is so far not known how such fluid compression controls the amplitude of mixing and reaction rates in porous media. Here we derive analytical predictions for the mixing width, the maximum reaction rate and the reaction intensity in compressed mixing fronts as a function of the Péclet and Damköhler numbers. We developed an experimental setup providing pore scale measurements of mixing and reaction rates in mixing fronts at the interface of converging flows. The theory accurately predicts the scaling of mixing and reaction with the Péclet number both in porous micromodels and simple Hele-Shaw cells. Additionally, we found that the presence of pore scale heterogeneities in the porous micromodels enhances reaction rates by a factor of 4 compared to the Hele-Shaw cells. Using numerical simulations of pore scale velocity fields, we attributed this phenomenon to the enhancement of pore-scale compression due to the presence of grains in accelerating flows. These findings provide new insights into the dynamics of mixing-induced reactions in porous media.

International audience; A microfluidic laboratory recently opened at Synchrotron SOLEIL, dedicated to in-house research and external users. Its purpose is to provide the equipment and expertise that allow the development of microfluidic systems adapted to the beamlines of SOLEIL as well as other light sources. Such systems can be used to continuously deliver a liquid sample under a photon beam, keep a solid sample in a liquid environment or provide a means to track a chemical reaction in a time-resolved manner. The laboratory provides all the amenities required for the design and preparation of soft-lithography microfluidic chips compatible with synchrotron-based experiments. Three examples of microfluidic systems that were used on SOLEIL beamlines are presented, which allow the use of X-ray techniques to study physical, chemical or biological phenomena. © 2020 International Union of Crystallography.

[PHYS]Physics [physics] - Abstract
International audience; Anomalous transport of solutes and suspensions in confined environments have drastic consequences for biogeochemical processes, including chemical reactions and microbial activities. While the impact of the host medium structural heterogeneity on transport has been investigated extensively, little is known about the coupling between such heterogeneity and sedimentation associated to density mismatch between the transported substance and the surrounding fluid. Recently, it has been shown that the sedimentation profile of a diluted colloid suspension, transported by a homogeneous flow field through a planar fracture, decays as the inverse of the square root of the distance from inlet.Here, we use microfluidics and time-lapse video-microscopy to investigate the impact of host medium heterogeneity on Brownian particles sedimentation in a suspension with a low volume fraction. We compare longitudinal sedimentation profiles in homogeneous and heterogeneous horizontal flow conditions. Our preliminary results show that: i) when performing the experiment in a homogeneous velocity field (a straight channel, mimicking a fracture), we determine that the sedimentation profile follows the inverse of the square root of the distance from the inlet, ii) using a porous medium replica, made out of cylindrical pillars of random size and position, the sedimentation profiles deviate from the one obtained in homogeneous conditions, iii) in both cases, the number of sedimented particles at the beginning traveled distance is lower than expected, due to a verticalheterogeneous distribution of particles in the suspension.Our work illustrates that heterogeneous porous material will impact the sedimentation and could be a contribution to comprehension of particle aggregates or bacteria edimentation.

International audience; n subsurface environments, bacteria play a major role in controlling the kinetics of a broad range of bio-geochemical reactions. In such environments, nutrients uxes and solute concentrations needed for bacteriametabolism may be highly variable in space and intermittent in time. This can lead to the formation of reactivehotspots where and when conditions are favorable to particular microorganisms, hence inducing biogeochemicalreaction kinetics that dier signicantly from those measured in homogeneous model environments. To investi-gate the impact of chemical gradients on the spatial structure and growth dynamics of subsurface microorganismpopulations, we develop microuidic cells allowing for a precise control of ow and chemical gradient conditions,as well as quantitative monitoring of the bacteria's spatial distribution and early-stage biolm development.Using the non-motile Escherichia coli JW1908-1 strain and Gallionella capsiferriformans ES-2 as modelorganisms, we investigate the behavior and development of bacteria over a range of single and double con-centration gradients in the concentrations of nutrients, electron donors and electron acceptors. We measurebacterial activity and population growth locally in precisely known hydrodynamic and chemical environments.This approach allows time-resolved monitoring of the location and intensity of reactive hotspots in micromodelsas a function of the ow and chemical gradient conditions. We compare reactive microbial hotspot dynamics inour micromodels to classic growth laws and well-known growth parameters for the laboratory model bacteriaEscherichia coli, namely Michaelis-Menten-Monod nutrients uptake and Doop's growth law.The validated growth laws are then integrated into a mixing model quantifying the dynamics of nutrientgradients in shear ows. The main objective is to investigate the inuence of combined chemical and velocitygradients on biogeochemical reactions kinetics and biomass production. We discuss the consequences of theseresults in the context of biomass production in heterogeneous velocity and chemical gradients.

International audience; Porous media in which different fluid phases coexist are common in nature (e.g., vadose zone and gas-oil reservoirs). In partially saturated porous media, the intricate spatial distributions of the wetting and nonwetting phases causes their flow to be focused onto preferential paths. Using a novel 2-D experimental setup allowing pore-scale measurement of concentration fields in a controlled unsaturated flow, we highlight mechanisms by which mixing of an invading fluid with the resident fluid is significantly enhanced when decreasing saturation. The mean scalar dissipation rate is observed to decrease slowly in time, while under saturated conditions it decays rapidly. This slow decrease is due to sustained longitudinal solute fingering, which causes concentration gradients to remain predominantly transverse to the average flow. Consequently, the effective reactivity is found to be much larger than under saturated conditions. These results provide new insights into the role that multiphase flows play on mixing/reaction in porous media.

International audience; In partially saturated porous media, the spatial distribution of wetting (e.g., water) and non-wetting (e.g., air) phases causes the liquid flow to be focused onto narrow and complex flow paths, leaving large volumes of wetting fluid trapped in between non-wetting phase clusters. The impact of the resulting highly heterogeneous wetting fluid velocity distributions on the dispersion and mixing of a solute in this wetting phase is critical for predicting reactive transport processes that take place in partially saturated porous media. We study the dependence of dispersion and mixing on the saturation degree using a 2D experimental setup consisting of cylindrical grains built using soft lithography. The joint injection of the two phases (wetting and non-wetting) provides a controlled homogeneous saturation in the medium. The simultaneous measurement of the flow velocity field, the spatial distribution of the wetting and non-wetting phases, and the tracer concentration field are used to investigate the relationship between the flow field complexity induced by desaturation and dispersion/mixing properties.We analyze the temporal behavior of the mean concentration gradient and the scalar dissipation rate, which quantify the temporal variation of the concentration variability and the potential for mixing-controlled chemical reactivity. The formation of preferential flowpaths in unsaturated flows is found to have an important impact on the mixing behavior. While the mean concentration gradient decays in time for saturated flow following the classical diffusive smoothing of concentration gradients, the creation of highly channelized finger structures in unsaturated flows induces persistently large concentration gradients which decay slowly in time. The highly resolved concentration field images show that this effect is due to i) a drastic increase of the surface available for creating concentration gradients across the finger boundaries, ii) the existence of dead-ends with a wide range of sizes, and iii) the recursive coalescence of tracer fingers at critical bottle necks formed between air clusters. These results suggest that large concentration gradients may persist over a broad range of times in unsaturated media thus affecting the reactivity of hydrological systems.

International audience; Effective reaction rates in porous media are controlled by the spatial organization of chemical species concentrations at the pore scale. From high resolution millifluidic pore scale imaging of reactive tracers we report experimental evidence of the formation of well-developed lamellar structures in reactive mixtures transported through porous media (de Anna et al., Environ. Sci. Technol., 2014). The latter are highlighted by a chemioluminescent reaction producing photons that localize along spatially coherent lines, representing hotspots of mixing and reaction at pore scale. These elongated spatial structures are naturally created by the stretching action of the pore scale velocity field, which induces a dynamic deformation of the material elements carrying solutes (Le Borgne et al., Phys. Rev. Lett., 2013). This particular spatial organization is shown to have a major impact on global reactivity by increasing the surface available for reactive mixing and by enhancing local chemical gradients (de Anna et al., Geophys. Res. Lett. 2014). We quantify this phenomenon for different flow topologies using a reactive lamella representation, which links fluid deformation, diffusion and reaction at the elementary scale. The upscaled reaction rates, estimated by integrating the distribution of local deformation rates, are shown to follow different temporal behavior depending on the distribution of local velocity gradients. This approach allows for the systematic evaluation of the temporal evolution of upscaled reaction rates, and establishes a direct link between the global reaction efficiency and the spatial characteristics of the underlying pore scale flow field.References:[1] P. de Anna, J.

International audience; Pore scale characterization of flow velocities and concentration spatial distributions is a key to understanding non-Fickian transport and mixing in porous media. We present a millifluidic setup aimed at investigating those processes in transparent porous media, at the pore scale. The porous media are quasi-2D, consisting of a Hele-Shaw cell containing cylindrical grains. They are made by soft lithography from a numerical model and provide full control on the geometry (medium porosity, permeability and heterogeneity). The setup allows for the study of primary drainage/imbibition, or the joint continuous injection of two fluids (e. g. water and air). A camera records the distributions of fluid phases, the position of solid tracers, and spatially-resolved images of light emissions inside the flow cell. The pore scale velocity field is thus measured from particle tracking, while pore scale concentration fields are measured accurately in passive transport experiments, using fluorescein; both continuous injection and finite volume solute injections can be achieved. Using two chemo-luminescent liquids, the reaction of which produces photons in addition to the reaction product, we are also able to study the local production rate of the reaction product as the reactive liquids flow through the system [1]. Pressure drops across the medium are also measured. This complete characterization (phase distributions, velocity and concentration fields, pressure drops) of the system allows to explain non-Fickian behaviors and test models that upscale transport and mixing properties from pore scale data. As examples, we shall discuss the upscaling of transport from the knowledge of Lagrangian velocities and the relationships between conservative and reactive transport under mixing-limited conditions (very large Damkhöler number). Other applications include the prediction of the mixing rate from the sole knowledge of the flow stretching [2], and the characterization of mixing by unsaturated flows [3].[1] P. de Anna et al.

International audience; Mixing and reactive transport are primarily controlled by the interplay between diffusion, advection and reaction at pore scale. Yet, how the distribution and spatial correlation of the velocity field at pore scale impact these processes is still an open question. Here we present an experimental investigation of the distribution and correlation of pore scale velocities and its relation with upscaled dispersion. We use a quasi two-dimensional (2D) horizontal set up, consisting of two glass plates filled with cylinders representing the grains of the porous medium : the cell is built by soft lithography technique, wich allows for full control of the system geometry. The local velocity field is quantified from particle tracking velocimetry using microspheres that are advected with the pore scale flow. Their displacement is purely advective, as the particle size is chosen large enough to avoid diffusion. We thus obtain particle trajectories as well as lagrangian velocities in the entire system. The measured velocity field shows the existence of a network of preferential flow paths in channels with high velocities, as well as very low velocity in stagnation zones, with a non Gaussian distribution. Lagrangian velocities are long range correlated in time, which implies a non-fickian scaling of the longitudinal variance of particle positions. To upscale this process we develop an effective transport model, based on correlated continous time random walk, which is entirely parametrized by the pore scale velocity distribution and correlation. The model predictions are compared with conservative tracer test data for different Peclet numbers. Furthermore, we investigate the impact of different pore geometries on the distribution and correlation of Lagrangian velocities and we discuss the link between these properties and the effective dispersion behavior.

La pérennisation de la valorisation agricole des boues résiduaires passe par une optimisation des techniques d'épandage. Dans le cas présent, nous nous sommes focalisés sur les phénomènes intervenant sur les disques qui constituent la table d'épandage, en tenant compte à la fois des caractéristiques rhéologiques du matériau à épandre et des réglages mécaniques du matériel. On montre d'abord par des expériences de rhéométrie qu'aux faibles contraintes, les boues ne peuvent s'écouler de manière stable: la déformation totale du matériau résulte d'une compétition entre la restructuration pendant la phase de repos précédant le cisaillement et la déstructuration due au cisaillement. De plus, lors du cisaillement avec une surface lisse, un glissement apparaît dans la même gamme de contrainte, à partir d'une déformation critique. Il se forme une fine couche de liquide newtonien entre la surface qui induit le cisaillement et le reste du matériau dans l'entrefer. Au delà d'une contrainte critique, l'écoulement devient homogène, quelque soit la nature de la surface, lisse ou rugueuse. A partir de travaux sur maquette, nous avons analysé la déformation d'un échantillon de fluide à seuil engendrée par l'application d'une force centrifuge d'intensité croissante, en accélérant progressivement la vitesse de rotation du disque. On montre que la dynamique de l'étalement se résume en trois phases distinctes. Aux faibles vitesses de rotation, le matériau se comporte comme un solide viscoélastique et subit de faibles déformations élongationnelles. Quand la vitesse de rotation dépasse une valeur critique, la déformation n'est plus homogène: le matériau se comporte comme un liquide en périphérie, et comme un solide au centre de l'échantillon. Seule la partie liquide s'étale en formant un bourrelet. On montre ainsi que les paramètres viscoélastiques du matériau et l'initiation de l'écoulement sont étroitement liés: plus le seuil de contrainte est élevé, plus la vitesse critique est grande. Enfin, l'étalement se localise au sein de digitations qui se forment à partir du bourrelet. Finalement, on montre qu'au cours de l'épandage les paquets de boues arrivant sur la table d'épandage ne sont pas cisaillés sous l'action de la force centrifuge, mais ils subissent une élongation puis une fragmentation avant d'être projeté à la sortie du disque. On démontre au passage que les pâles n'ont aucune utilité sur le procédé d'émiettement.
