Driven binary mixtures: Clustering and giant diffusion
– We study noise-assisted transport in a binary mixture of overdamped interacting particles. As one species (termed “active”) is subject to a weak dc drive, the other one (termed “passive”) can be dragged along due to the clustering of particles of both species. On increasing the external drive, clusters of different size fragment at different thresholds that depend on the mixture temperature, ...
متن کاملClustering in Interfering Binary Mixtures
Colloids are binary mixtures of molecules with one type of molecule suspended in another. It is believed that at low density typical configurations will be well-mixed throughout, while at high density they will separate into clusters. We characterize the high and low density phases for a general family of discrete interfering binary mixtures by showing that they exhibit a “clustering property” ...
متن کاملLateral diffusion in binary mixtures of cholesterol and phosphatidylcholines.
The lateral diffusion of a fluorescent-labeled phospholipid, phosphatidyl-N-(4-nitrobenzo-2-oxa-1,3,-diazole)ethanolamine, has been measured in binary mixtures of cholesterol and dimyristoyl phosphatidylcholine at temperatures both above and below 23.8 degrees C, the chain-melting transition temperature of this phosphatidylcholine. There is a temperature-composition region, approximately temper...

متن کاملRotational tracer diffusion in binary colloidal sphere mixtures.
We demonstrate that tracer/host size asymmetry and electrostatic interactions strongly affect rotational self-diffusion in binary mixtures of charged colloidal tracer and host spheres. Tracer diffusion coefficients, measured with time-resolved phosphorescence anisotropy, are compared with calculations of rotational diffusion including two- and three-particle hydrodynamic interactions. We also s...
