Single-particle motion in colloids: force-induced diffusion
We study the fluctuating motion of a Brownian-sized probe particle as it is dragged by a constant external force through a colloidal dispersion. In this nonlinearmicrorheology problem, collisions between the probe and the background bath particles, in addition to thermal fluctuations of the solvent, drive a long-time diffusive spread of the probe’s trajectory. The influence of the former is det...
متن کاملThermodiffusion of charged colloids: single-particle diffusion.
An expression for the single-particle thermal diffusion coefficient of a charged colloidal sphere is derived on the basis of force balance on the Brownian time scale in combination with thermodynamics. It is shown that the single-particle thermal diffusion coefficient is related to the temperature dependence of the reversible work necessary to build the colloidal particle, including the core, t...
متن کاملSingle-particle thermal diffusion of charged colloids: double-layer theory in a temperature gradient.
The double-layer contribution to the single-particle thermal diffusion coefficient of charged, spherical colloids with arbitrary double-layer thickness is calculated and compared to experiments. The calculation is based on an extension of the Debye-Hückel theory for the double-layer structure that includes a small temperature gradient. There are three forces that constitute the total thermophor...
متن کاملSingle-particle tracking of janus colloids in close proximity.
We describe algorithms and an experimental method based on differential interference contrast microscopy to discriminate optically anisotropic colloidal spheres under situations where diffraction owing to their close proximity causes overlapping images. The data analysis is applied to modulated optical nanoprobes (MOONs) that are coated with metal on one hemisphere. These methods enable single-...
متن کاملForce-induced diffusion in microrheology.
We investigate the force-induced diffusive motion of a tracer particle inside a glass-forming suspension when a strong external force is applied to the probe (active nonlinear microrheology). A schematic model of mode-coupling theory introduced recently is extended to describe the transient dynamics of the probe particle, and used to analyze recent molecular-dynamics simulation data. The model ...
