Journal ArticleDOI
Laponite: What Is the Difference between a Gel and a Glass?
TL;DR: Solutions of the synthetic clay Laponite are strongly viscoelastic, even at very low particle concentrations, and the formation of a gel, evidenced by the existence of a fractal network, has been invok...
Journal ArticleDOI
Two-dimensional turbulence: a review of some recent experiments
Hamid Kellay,Walter I. Goldburg +1 more
TL;DR: A review of recent experiments in two-dimensional turbulence is presented in this paper, where work on flowing soap films and on thin layers of fluid driven electromagnetically is covered, and theoretical notions of turbulence in two and three dimensions are introduced.
Journal ArticleDOI
Aging of a colloidal “Wigner” glass
TL;DR: During the aging of a colloidal glass, which is obtained for extremely low volume fractions due to strong electrostatic repulsions, leading to the formation of a Wigner glass, a new crossover between a complete and incomplete decay of the correlation function is observed, accompanied by an increase in the non-ergodicity parameter.
Journal ArticleDOI
Delayed fracture of an inhomogeneous soft solid
Daniel Bonn,Hamid Kellay,Hamid Kellay,Michaël Prochnow,Michaël Prochnow,Karim Ben-Djemiaa,Karim Ben-Djemiaa,Jacques Meunier,Jacques Meunier +8 more
TL;DR: The spontaneous fracture of polymer gels was studied and the activation energy for crack nucleation in arbitrary dimension and accounting for the inhomogeneity of the gel network in terms of its fractal dimension were calculated.
Journal ArticleDOI
Inhibition of the finite-time singularity during droplet fission of a polymeric fluid.
TL;DR: It is shown that the addition of very small amounts of polymer inhibits this singularity in an abrupt way and gives rise, after a period of self-similar dynamics as for simple liquids, to long-lived cylindrical necks or filaments which thin exponentially in time.
