We conduct molecular dynamics simulations of a bidisperse Kob-Andersen (KA) glass former, modified to add in additional polydispersity. The original KA system is known exhibit dynamical heterogeneity. Prior work defined propensity, the mean motion particle averaged over reconstructing initial positions all particles but with randomized velocities. existence propensity shows that structure and a...

Macroscopic properties of electrorheological (ER) fluids are often determined by the spatial arrangement of the suspended particles. We investigate the microstructure of polydisperse ER fluids at low concentrations in a DC electric field. Optical microscopy reveals that the particles with polydispersity in size or in both size and dielectric property are mixed in stable single particle width ch...

2014 A « critical » degree of polydispersity is postulated beyond which liquid and crystalline states merge. For a system with a triangular particle-size distribution, the disappearance of the melting transition is estimated to occur at levels of just less than 30 % polydispersity. J. Physique Lett. 46 (1985) L-229 L-232 ~ 15 MARS 1985, : -1 Classification Physics Abstracts 64. 70D 82.70 Freezi...

Geophysical mass flows involve particles of different sizes, a property termed polydispersity. The granular column collapse is simplified experiment for studying transitional flows. Our research focuses on the role that polydispersity has velocity and runout distance dry immersed columns, undergoing numerical experimental study. results highlight does not have strong effect columns. On contrary...

There are a number of sources of information that give a mathematical description of the terms used in light scattering. However, these will not usually give assistance in understanding their use in the practical application of the technique. (Ref, 1,2,3,4,5,6) The following list of terms gives a descriptive defi nition, with notes on their specifi c use in the context of Dynamic Light Scatteri...

Inspired by the observations of a remarkably stable biaxial nematic phase [van den Pol et al., Phys. Rev. Lett. 103, 258301 (2009)], we investigate the effect of size polydispersity on the phase behavior of a suspension of boardlike particles. By means of Onsager theory within the restricted orientation (Zwanzig) model we show that polydispersity induces a novel topology in the phase diagram, w...
