Drying by Cavitation and Poroelastic Relaxations in Porous Media with Macroscopic Pores Connected by Nanoscale Throats
Olivier Vincent, David A. Sessoms, Erik J. Huber +2
We investigate the drying dynamics of porous media with two pore diameters separated by several orders of magnitude. Nanometer-sized pores at the edge of our samples prevent air en…
Unexpected spatial distribution of bubble rearrangements in coarsening foams
David A. Sessoms, Hugo Bissig, Agnès Duri +2
Foams are ideal model systems to study stress-driven dynamics, as stress-imbalances within the system are continuously generated by the coarsening process, which unlike thermal flu…
Ultra-long range correlations of the dynamics of jammed soft matter
Simona Maccarrone, Giovanni Brambilla, Olivier Pravaz +8
We use Photon Correlation Imaging, a recently introduced space-resolved dynamic light scattering method, to investigate the spatial correlation of the dynamics of a variety of jamm…
Multiple dynamic regimes in concentrated microgel systems
David A. Sessoms, Irmgard Bischofberger, Luca Cipelletti +1
We investigate dynamical heterogeneities in the collective relaxation of a concentrated microgel system, for which the packing fraction can be conveniently varied by changing the t…
Resolving long-range spatial correlations in jammed colloidal systems using photon correlation imaging
Agnes Duri, David A. Sessoms, Veronique Trappe +1
We introduce a new dynamic light scattering method, termed photon correlation imaging, which enables us to resolve the dynamics of soft matter in space and time. We demonstrate pho…
Evolution of particle-scale dynamics in an aging clay suspension
R. Bandyopadhyay, D. Liang, H. Yardimci +5
Multispeckle x-ray photon correlation spectroscopy was employed to characterize the slow dynamics of a colloidal suspension formed by highly-charged, nanometer-sized disks. At scat…
