Phagocytic properties of lung alveolar wall cells [PDF]
, 1974 For the purpose to define the mechanism of heavy metal intoxication by inhalation, morphologic observations were made on rat lungs after nasal instillation of iron colloid particles of positive and negative electric charges. Histochemical observation was

Manipulation of Colloids by Nonequilibrium Depletion Force in Temperature Gradient [PDF]
, 2009 The non-equilibrium distribution of colloids in a polymer solution under a temperature gradient is studied experimentally. A slight increase of local temperature by a focused laser drives the colloids towards the hot region, resulting in the trapping of the colloids irrespective of their own thermophoretic properties.

Cross-interaction drives stratification in drying film of binary colloidal mixtures [PDF]
Phys. Rev. Lett. 118, 108002 (2017), 2017 When a liquid film of colloidal solution consisting of particles of different sizes is dried on a substrate, the colloids often stratify, where smaller colloids are laid upon larger colloids. This phenomenon is counter intuitive because larger colloids which have smaller diffusion constant are expected to remain near the surface during the drying ...

A Dissipative-Particle-Dynamics Model for Simulating Dynamics of Charged Colloid
, 2013 A mesoscopic colloid model is developed in which a spherical colloid is represented by many interacting sites on its surface. The hydrodynamic interactions with thermal fluctuations are taken accounts in full using Dissipative Particle Dynamics, and the ...

Phase separation around heated colloid in bulk and under confinement
, 2018 We study the non-equilibrium coarsening dynamics of a binary liquid solvent around a colloidal particle in a presence of a time-dependent temperature gradient that emerges after temperature quench of a suitably coated colloid surface.

Phase separation dynamics in colloid-polymer mixtures: the effect of interaction range
, 2012 Colloid-polymer mixtures may undergo either fluid-fluid phase separation or gelation. This depends on the depth of the quench (polymer concentration) and polymer-colloid size ratio.

Effects of colloid polydispersity on the phase behaviour of colloid-polymer mixtures [PDF]
, 2004 We study theoretically the equilibrium phase behaviour of a mixture of polydisperse hard-sphere colloids and monodisperse polymers, modelled using the Asakura-Oosawa model within the free volume approximation of Lekkerkerker et al. We compute full phase diagrams in the plane of colloid and polymer volume fractions, using the moment free energy method ...

The structure of colloid-polymer mixtures
, 1999 We investigate the structure of colloid-polymer mixtures by calculating the structure factors for the Asakura-Oosawa model in the PY approximation. We discuss the role of potential range, polymer concentration and polymer-polymer interactions on the ...
