Gelation and Re-entrance in Mixtures of Soft Colloids and Linear Polymers of Equal Size
D. Parisi, D. Truzzolillo, A. H. Slim +6
Liquid mixtures composed of colloidal particles and much smaller non-adsorbing linear homopolymers can undergo a gelation transition due to polymer-mediated depletion forces. We no…
Instabilities in freely expanding sheets of associating viscoelastic fluids
S. Arora, A. Louhichi, D. Vlassopoulos +2
We use the impact of drops on a small solid target as a tool to investigate the behavior of viscoelastic fluids under extreme deformation rates. We study two classes of transient n…
Static and Dynamic Properties of Block-Copolymer Based Grafted Nanoparticles Across the Non-Ergodicity Transition
Daniele Parisi, Jose Ruiz-Franco, Yingbo Ruan +3
We present a systematic investigation of static and dynamic properties of block copolymer micelles with crosslinked cores, representing model polymer-grafted nanoparticles, over a…
Static and Dynamic Properties of Block-Copolymer Based Grafted Nanoparticles Across the Non-Ergodicity Transition
Daniele Parisi, José Ruiz-Franco, Yingbo Ruan +4
We present a systematic investigation of static and dynamic properties of block copolymer micelles with crosslinked cores, representing model polymer-grafted nanoparticles, over a…
Wall slip in primitive chain network simulations of shear startup of entangled polymers and its effect on the shear stress undershoot
Yuichi Masubuchi, Dimitris Vlassopoulos, Giovanni Ianniruberto +1
In some recent experiments on entangled polymers of stress growth in startup of fast shear flows an undershoot in the shear stress is observed following the overshoot, i.e., before…
Short and soft: multi-domain organization, tunable dynamics and jamming in suspensions of grafted colloidal cylinders with small aspect ratio
Daniele Parisi, Yingbo Ruan, Guy Ochbaum +8
The yet virtually unexplored class of soft colloidal rods with small aspect ratio is investigated and shown to exhibit a very rich phase and dynamic behavior, spanning from liquid…
Biaxial extensional viscous dissipation in sheets expansion formed by impact of drops of Newtonian and non-Newtonian fluids
Ameur Louhichi, Carole-Ann Charles, Ty Phou +3
We investigate freely expanding liquid sheets made of either simple Newtonian fluids or solutions of high molecular water-soluble polymer chains. A sheet is produced by the impact…
Transition from confined to bulk dynamics in symmetric star-linear polymer mixtures
Daniele Parisi, Domenico Truzzolillo, Vishnu D. Deepak +2
We report on the linear viscoelastic properties of mixtures comprising multiarm star (as model soft colloids) and long linear chain homopolymers in a good solvent. In contrast to e…
Crystal-to-crystal transition of ultrasoft colloids under shear
J. Ruiz-Franco, J. Marakis, N. Gnan +5
Ultrasoft colloids typically do not spontaneously crystallize, but rather vitrify, at high concentrations. Combining in-situ rheo-SANS experiments and numerical simulations we show…
