When gel and glass meet: A mechanism for multistep relaxation
Pinaki Chaudhuri, Ludovic Berthier, Pablo I. Hurtado +1
We use computer simulations to study the dynamics of a physical gel at high densities where gelation and the glass transition interfere. We report and provide detailed physical und…
Structural Relaxation of a Gel Modeled by Three Body Interactions
Shibu Saw, Niels L. Ellegaard, Walter Kob +1
We report a molecular dynamics simulation study of a model gel whose interaction potential is obtained by modifying the three body Stillinger-Weber model potential for silicon. The…
A microscopic model for colloidal gels with directional effective interactions: Network induced glassy dynamics
Emanuela Del Gado, Walter Kob
By means of molecular dynamics, we study the structure and the dynamics of a microscopic model for colloidal gels at low volume fractions. The presence of directional interactions…
Universal scattering behavior of co-assembled nanoparticle-polymer clusters
J. Fresnais, J. -F. Berret, L. Qi +7
Water-soluble clusters made from 7 nm inorganic nanoparticles have been investigated by small-angle neutron scattering. The internal structure factor of the clusters was derived an…
Analysis of a Lennard-Jones fcc structure melting to the corresponding frozen liquid: differences between the bulk and the surface
N. Olivi-Tran, A. Faivre
We computed a Lennard Jones frozen liquid with a free surface using classical molecular dynamics. The structure factor curves on the free surface of this sample was calculated for…
