Intrinsic aging and effective viscosity in the slow dynamics of a soft glass with tunable elasticity
Laurence Ramos, Luca Cipelletti
We investigate by rheology and light scattering the influence of the elastic modulus, , on the slow dynamics and the aging of a soft glass. We show that the slow dynamics and…
Swollen Micelles Plus Hydrophobically Modified Hydrosoluble Polymers in Aqueous Solutions: Decoration Versus Bridging. a Small Angle Neutron Scattering Study
Mohammed Filali, Raymond Aznar, Mattias Svenson +2
In this paper we examine the effective interactions introduced between the droplets of an oil in water microemulsion upon progressive addition of hydrophobically modified water sol…
Robust Phase Behavior of Model Transient networks
Mohammed Filali, Mohamed J. Ouazzani, Erir Michel +3
In order to study the viscoelastic properties of certain complex fluids which are described in terms of a multiconnected transient network we have developed a convenient model syst…
Percolation in a Model Transient Network: Rheology and Dynamic Light Scattering
Eric Michel, Mohammed Filali, Raymond Aznar +2
Step strain experiments and dynamic light scattering measurements are perfomed to characterize the dynamic behavior of an o/w droplet microemulsion into which is incorporated a tel…
Analysis by the Two-Fluids Model of the Dynamical Behavior of a Viscoelastic Fluid Probed by Dynamic Light Scattering
Jacqueline Appell, Eric Michel, Gregoire Porte +1
The dynamic properties of a model transient network have been studied by dynamic light scattering. The network is formed by microemulsion droplets linked by telechelic polymers (mo…
Shear-melting of a hexagonal columnar crystal by proliferation of dislocations
L. Ramos, F. Molino
A hexagonal columnar crystal undergoes a shear-melting transition above a critical shear rate or stress. We combine the analysis of the shear-thinning regime below the melting with…
