Relationship between particle elasticity, glass fragility, and structural relaxation in dense microgel suspensions.
"Fragile" glassy materials, which include most polymeric materials and organic liquids, exhibit a steep and super-Arrhenius dependence of relaxation time with temperature upon the glass transition and have been extensively studied. Yet, a full understanding of strong glass formers that exhibit an Arrhenius dependence on temperature is still lacking. In this work, we have investigated the glassy...
متن کاملParticle stress in suspensions of soft objects.
In a suspension of extended objects such as colloidal particles, capsules or vesicles, the contribution of particles to the stress is usually evaluated by first determining the stress originating from a single particle (e.g. via integrating the fluid stress over the surface of a particle) and then adding up the contributions of individual particles. While adequate for a computation of the avera...
متن کاملActive and Passive Particle Transport in Dense Colloidal Suspensions
Acknowledgments First, I would like to thank Prof. Matthias Fuchs for giving me the opportunity to work on the very interesting subject of the mode-coupling theory of the glass transition and especially to contribute to the exciting new developments in this field. I also acknowledge the opportunity to participate in different teaching and seminar activities, which helped me to learn unconventio...
متن کاملUnsteady flow and particle migration in dense, non-Brownian suspensions
We present experimental results on dense corn-starch suspensions as examples of non-Brownian, nearly hard particles that undergo continuous and discontinuous shear thickening (DST) at intermediate and high densities, respectively. Our results offer strong support for recent theories involving a stress-dependent effective contact friction among particles. We show, however, that in the DST regime...
متن کاملDispersion of sound in dilute suspensions with nonlinear particle relaxation.
The theory accounting for nonlinear particle relaxation (viscous and thermal) has been applied to the prediction of dispersion of sound in dilute suspensions. The results suggest that significant deviations exist for sound dispersion between the linear and nonlinear theories at large values of omegatau(d), where omega is the circular frequency and tau(d) is the Stokesian particle relaxation tim...
