Multiscale Filler Structure in Simplified Industrial Nanocomposite Silica/SBR Systems Studied by SAXS and TEM
Guilhem Baeza, ANNE-CAROLINE GENIX, Christophe Degrandcourt +4
Simplified silica (Zeosil 1165 MP) and SBR (140k carrying silanol end-groups) nanocomposites have been formulated by mixing of a reduced number of ingredients with respect to indus…
Nucleation and growth of micellar polycrystals under time-dependent volume fraction conditions
A. Louhichi, E. Tamborini, N. Ghofraniha +5
We study the freezing kinetics of colloidal polycrystals made of micelles of Pluronic F108, a thermosensitive copolymer, to which a small amount of silica nanoparticles of size com…
Cluster glasses of ultrasoft particles
Daniele Coslovich, Marco Bernabei, Angel J. Moreno
We present molecular dynamics (MD) simulations results for dense fluids of ultrasoft, fully-penetrable particles. These are a binary mixture and a polydisperse system of particles…
Driving kinetically constrained models into non-equilibrium steady states: structural and slow transport properties
Francesco Turci, Estelle Pitard, Mauro Sellitto
Complex fluids in shear flow and biased dynamics in crowded environments exhibit counterintuitive features which are difficult to address both at theoretical level and by molecular…
Structure of nanoparticles embedded in micellar polycrystals
Elisa Tamborini, Neda Ghofraniha, Julian Oberdisse +2
We investigate by scattering techniques the structure of water-based soft composite materials comprising a crystal made of Pluronic block-copolymer micelles arranged in a face-cent…
Grain refinement and partitioning of impurities in the grain boundaries of a colloidal polycrystal
Neda Ghofraniha, Elisa Tamborini, Julian Oberdisse +2
We study the crystallization of a colloidal model system in presence of secondary nanoparticles acting as impurities. Using confocal microscopy, we show that the nanoparticles segr…
