Delayed elastic contributions to the viscoelastic response of foams
François A. Lavergne, Peter Sollich, Véronique Trappe
We show that the slow viscoelastic response of a foam is that of a power-law fluid with a terminal relaxation. Investigations of the foam mechanics in creep and recovery tests reve…
Multiple dynamic regimes in a coarsening foam
Fabio Giavazzi, Veronique Trappe, Roberto Cerbino
We use differential dynamic microscopy and particle tracking to determine the dynamical characteristics of a coarsening foam in reciprocal and direct space. At all wavevectors …
The glass transition of soft colloids
Adrian-Marie Philippe, Domenico Truzzolillo, Julian Galvan-Myoshi +4
We explore the glassy dynamics of soft colloids using microgels and charged particles interacting by steric and screened Coulomb interactions, respectively. In the supercooled regi…
Differential Dynamic Microscopy microrheology of soft materials: a tracking-free determination of the frequency-dependent loss and storage moduli
Paolo Edera, Davide Bergamini, Véronique Trappe +2
Particle tracking microrheology (PT-r) exploits the thermal motion of embedded particles to probe the local mechanical properties of soft materials. Despite its appealing concep…
Differential Dynamic Microscopy: Probing wave vector dependent dynamics with a microscope
Roberto Cerbino, Veronique Trappe
We demonstrate the use of an ordinary white-light microscope for the study of the q-dependent dynamics of colloidal dispersions. Time series of digital video images are acquired in…
Unexpected decoupling of stretching and bending modes in protein gels
Thomas Gibaud, Alessio Zaccone, Emanuela Del Gado +2
We show that gels formed by arrested spinodal decomposition of protein solutions exhibit elastic properties in two distinct frequency domains, both elastic moduli exhibiting a rema…
