Drops on soft solids : Free energy and double transition of contact angles

Sylvain Patinet — 2014-06-05T09:03:05Z

Lubbers L.A., Weijs H.H.,Botto L., Das S, Andreotti B. and Snoeijer J.H., J. Fluid Mech. 747, R1 (2014).
The equilibrium shape of liquid drops on elastic substrates is determined by minimising elastic and capillary free energies, focusing on thick incompressible substrates. The problem is governed by three length scales : the size of the drop $R$, the molecular size $a$, and the ratio of surface tension to elastic modulus $\gamma/E$. We show that the contact angles undergo two transitions (…)

Forbidden directions for the fracture of thin anisotropic sheets : an analogy with the Wulff plot

Sylvain Patinet — 2014-06-05T09:12:21Z

A. Takei, B. Roman, J. Bico, E. Hamm & F. Melo, Physical Review Letter, 110 144301 (2013)
It is often postulated that quasistatic cracks propagate along the direction allowing fracture for the lowest load. Nevertheless, this statement is debated, in particular for anisotropic materials. We performed tearing experiments in anisotropic brittle thin sheets that validate this principle in the case of weak anisotropy. We also predict the existence of forbidden directions and facets in (…)

A non-local rheology for granular flows across yield conditions

Sylvain Patinet — 2014-06-05T09:37:47Z

M. Bouzid, M. Trulsson, P. Claudin, E. Clément and B. Andreotti, Phys. Rev. Lett. 111, 238301 (2013).
The rheology of dense granular flows is studied numerically in a shear cell controlled at constant pressure and shear stress, confined between two granular shear flows. We show that a liquid state can be achieved even far below the yield stress, whose flow can be described with the same rheology as above the yield stress. A nonlocal constitutive relation is derived from dimensional (…)

Collective motion in an active suspension of E. coli bacteria

Sylvain Patinet — 2014-06-05T09:50:57Z

Jeremie Gachelin, Annie Rousselet, Anke Lindner, Eric Clement, NJP, accepted 2013.
We investigate experimentally the emergence of collective motion in the bulk of an active suspension of E. coli bacteria. When increasing the concentration from a dilute to a semi-dilute regime, we observe a continuous cross-over from a dynamical cluster regime to a regime of `bio-turbulence' convection patterns. We measure a length scale characterizing the collective motion as a function of the bacteria (…)

Book : “Heat Transfers and Related Effects in Supercritical Fluids”

Sylvain Patinet — 2015-01-30T09:50:33Z

by : Bernard Zappoli, Daniel Beysens, Yves Garrabos
Springer, serie : Fluid Mechanics and Its Applications 108
This book investigates the unique hydrodynamics and heat transfer problems that are encountered in the vicinity of the critical point of fluids. Emphasis is given on weightlessness conditions, gravity effects and thermovibrational phenomena. Near their critical point, fluids indeed obey universal behavior and become very compressible and expandable. Their comportment, when (…)

Microrheology to probe non-local effects in dense granular flows

Sylvain Patinet — 2015-03-26T10:07:24Z

M. Bouzid, M. Trulsson, P. Claudin, E. Clément and B. Andreotti, EPL, 109 (2015) 24002.
A granular material is observed to flow under the Coulomb yield criterion as soon
as this criterion is satisfied in a remote but contiguous region of space. We investigate this nonlocal effect using discrete element simulations, in a geometry similar, in spirit, to the experiment of Reddy et al. (Phys. Rev. Lett., 106 (2011) 108301) : a micro-rheometer is introduced to determine the influence of a (…)

The force of impacting rain

Sylvain Patinet — 2015-03-26T10:15:42Z

D. Soto, A. Borel De Larivière, X. Boutillon, C. Clanet and D. Quéré, Soft Matter, 2014, 10, 4929.
Drop impacts are difficult to characterize due to their transient, non-stationary nature. We discuss the force generated during such impacts, a key quantity for animals, plants, roofs or soil erosion. Although a millimetric drop has a modest weight, it can generate collision forces on the order of thousand times this weight. We measure and discuss this amplification, considering natural (…)

Droplets move over viscoelastic substrates by surfing a ridge

Antonin EDDI — 2016-02-18T13:36:49Z

Karpitschka S., Das S., van Gorcum M., Perrin H., Andreotti B. & Snoeijer J.H., Nature Comm., 6, 7891, (2015)
Liquid drops on soft solids generate strong deformations below the contact line, resulting from a balance of capillary and elastic forces. The movement of these drops may cause strong, potentially singular dissipation in the soft solid. Here we show that a drop on a soft substrate moves by surfing a ridge : the initially flat solid surface is deformed into a sharp ridge whose (…)

Water impacting on superhydrophobic macrotextures

Antonin EDDI — 2016-02-18T13:48:26Z

Anaïs Gauthier, Sean Symon, Christophe Clanet, David Quéré ; Nature Comm., 6, 8001, (2015)
It has been recently shown that the presence of macrotextures on superhydrophobic materials can markedly modify the dynamics of water impacting them, and in particular significantly reduce the contact time of bouncing drops, compared with what is observed on a flat surface. This finding constitutes a significant step in the maximization of water repellency, since it enables to minimize even further (…)

Turning bacterial suspensions into a "superfluid"

Antonin EDDI — 2016-02-18T13:48:07Z

H.M. Lopez, J. Gachelin, C. Douarche, H.Auradou, E. Clément ; Phys. Rev. Lett., 115, 28301, (2015)
The rheological response under simple shear of an active suspension of Escherichia coli is determined in a large range of shear rates and concentrations. The effective viscosity and the time scales characterizing the bacterial organization under shear are obtained. In the dilute regime, we bring evidence for a low-shear Newtonian plateau characterized by a shear viscosity decreasing with (…)

Effect of friction on the peeling test at zero-degrees

Antonin EDDI — 2016-02-18T13:51:33Z

S. Ponce, J. Bico, B. Roman ; Soft Matter, 11, 9281-9290, (2015)
We describe the peeling of an elastomeric strip adhering to a glass plate through van der Waals interactions in the limit of a zero peeling angle. In contrast to classical studies that predict a saturation of the pulling force, in this lap test configuration the force continuously increases, while a sliding front propagates along the tape. The strip eventually detaches from the substrate when the front reaches its end. (…)

Faraday wave lattice as an elastic metamaterial

Sylvain Patinet — 2016-05-31T08:02:12Z

L. Domino, M. Tarpin, S. Patinet, and A. Eddi ; Phys. Rev. E 93, 050202(R), (2016)
Metamaterials enable the emergence of novel physical properties due to the existence of an underlying subwavelength structure. Here, we use the Faraday instability to shape the fluid-air interface with a regular pattern. This pattern undergoes an oscillating secondary instability and exhibits spontaneous vibrations that are analogous to transverse elastic waves. By locally forcing these waves, we fully (…)

Thibault Chastel, Philippe Gondret and Anne Mongruel : Journal of Fluid Mechanics, Volume 805 October 2016, pp. 577-590
We investigate in detail the dynamics of bouncing of a fluid-immersed solid sphere onto a textured wall at moderate Reynolds and Stokes numbers. Using high-frequency interferometric measurements, the dynamics of the sphere is resolved in time and space, before, during and after collision with the wall. The critical Stokes number for bouncing is shown to be significantly (…)

M. Segall, R. Cornette, A.-C. Fabre, R. Godoy-Diana, A. Herrel ; Proc. R. Soc. B, 283, 20161645, (2016)
Evolutionary trajectories are often biased by developmental and historical factors. However, environmental factors can also impose constraints on the evolutionary trajectories of organisms leading to convergence of morphology in similar ecological contexts. The physical properties of water impose strong constraints on aquatic feeding animals by generating pressure waves that can alert (…)

I. Ashraf, R. Godoy-Diana, J. Halloy, B. Collignon, B. Thiria Journal of the Royal Society Interface 13 20160734 (2016)
In this work, we address the case of red nose tetra fish Hemigrammus bleheri swimming in groups in a uniform flow, giving special attention to the basic interactions and cooperative swimming of a single pair of fish. We first bring evidence of synchronization of the two fish, where the swimming modes are dominated by ‘out-phase' and ‘in-phase' configurations. We show that (…)

V. Cognet, S. Courrech du Pont, I. Dobrev, F. Massouh, B. Thiria ; Proc. Roy. Soc. A, 473, (2017)
Wind energy is becoming a significant alternative solution for future energy production. Modern turbines now benefit from engineering expertise, and a large variety of different models exists, depending on the context and needs. However, classical wind turbines are designed to operate within a narrow zone centred around their optimal working point. This limitation prevents the use of (…)

Pan Jia, Bruno Andreotti, and Philippe Claudin, PNAS (2017)
Abstract : Explaining the unexpected presence of dune-like patterns at the surface of the comet 67P/Churyumov–Gerasimenko requires conceptual and quantitative advances in the understanding of surface and outgassing processes. We show here that vapor flow emitted by the comet around its perihelion spreads laterally in a surface layer, due to the strong pressure difference between zones illuminated by sunlight and those in shadow.

Rukmava Chatterjee, Daniel Beysens, and Sushant Anand, Adv. Mater., 1807812 (2019)
Abstract : Preventing water droplets from transitioning to ice is advantageous for numerous applications. It is demonstrated that the use of certain phase-change materials, which are in liquid state under ambient conditions and have melting point higher than the freezing point of water, referred herein as phase-switching liquids (PSLs), can impede condensation–frosting lasting up to 300 and 15 times longer (…)

Orencio Duran Vinent, Bruno Andreotti, Philippe Claudin and Christian Winter, Nature Geoscience (2019)
Subaqueous and aeolian bedforms are ubiquitous on Earth and other planetary environments. However, it is still unclear which hydrodynamic mechanisms lead to the observed variety of morphologies of self-organized natural patterns such as ripples, dunes or compound bedforms. Here we present simulations with a coupled hydrodynamic and sediment transport model that resolve the initial and (…)

By C. Gadal, C. Narteau, S. Courrech du Pont, O. Rozier and P. Claudin in Geology (2020) 48 (4) : 343–347.
Dune fields are commonly associated with periodic patterns that are among the most recognizable landscapes on Earth and other planetary bodies. However, in zones of limited sediment supply, where periodic dunes elongate and align in the direction of the resultant sand flux, there has been no attempt to explain the emergence of such a regular pattern. Here, we show, by means of (…)

R. Baggio, O. U. Salman, and L. Truskinovsky Phys. Rev. E 107, 025004 – Published 24 February 2023 : link article
Plastic deformations in crystals produce microstructures with randomly oriented patches of unstressed lattice forming complex textures. We use a mesoscopic Landau-type tensorial model of crystal plasticity to show that in such textures rotations can originate from crystallographically exact microslips which self organize in the form of laminates of a pseudotwin type.

Mechanical stress driven by rigidity sensing governs epithelial stability

Sylvain Patinet — 2023-12-06T09:05:09Z

S. Sonam et al. Nature Physics, 19, 2023, 132–141.
Epithelia act as barriers against environmental stresses. They are continuously exposed to various mechanical stress and abrasion, which impact epithelial integrity. The impact of the environment on epithelial integrity remains elusive. By culturing epithelial cells on two-dimensional hydrogels, we observe a loss of epithelial monolayer integrity on soft substrates through spontaneous hole formation. These monolayer ruptures are associated (…)

Les paysages de dunes ne se limitent pas aux grandes collines ondulantes des déserts. Entre les dunes principales, sur des zones parfois compactes ou gravillonneuses, apparaissent aussi de petites formes sableuses de quelques mètres. Trop petites pour être qualifiées de dunes, trop grandes pour être de simples rides, ces structures éphémères interrogent : comment se forment-elles, et pourquoi persistent-elles parfois, alors que les théories développées jusqu'à prédisent leur disparition (…)

Self-Organization and Memory in a Disordered Solid Subject to Random Driving

We consider self-organization and memory formation in a mesoscopic model of an amorphous solid subject to a protocol of random shear confined to a strain range ±𝜖max. We develop proper readout protocols to show that the response of the driven system self-organizes to retain a memory of the strain range, which can be subsequently retrieved. Our findings generalize previous results obtained upon oscillatory driving and suggest that self-organization and memory formation of disordered materials (…)

Asymmetric bending boundary layer : The λ-test

Sylvain Patinet — 2025-07-01T22:15:30Z

In this paper, the MecaWet group investigates the mechanics of two asymmetric ribbons bound at one end and pulled apart at the other ends. They characterize the elastic junction near the bonding and conceptualize it as a bending boundary layer. While the size of this junction decreases with the pulling force, they observe the surprising existence of the binding angle as a macroscopic signature of the bending stiffnesses.
The results thus challenge the standard assumption of neglecting (…)

To fabricate large-scale structures using colloidal particle self-assembly, one of the main challenges is to prevent kinetic trapping in metastable states. Therefore, interactions and colloids must be carefully chosen to ensure selectivity to guide the assembly, reversibility to enable large-scale reorganization and flexibility to finely tune colloid positioning.

Flexible fibers are common in nature and technology, from biological filaments to nanomaterials and pollutants. However, sorting these deformable, anisotropic objects in flow remains difficult. We show that microfluidic devices with tilted pillar arrays-originally designed for spherical particles-can be adapted to separate fibers by length. Unexpectedly, these arrays act as band-pass filters, causing lateral migration only for fibers whose lengths match the interpillar spacing. This (…)
