Interfacial dynamics in demixing systems with ultralow interfacial tension

D Aarts, RPA Dullens… - New Journal of …, 2005 - iopscience.iop.org
We report measurements on fluid–fluid phase separation in a colloid–polymer mixture,
which can be followed in great detail due to the ultralow interfacial tension. The use of the …

Interfacial dynamics and the static profile near a single wall in a model colloid–polymer mixture

D Aarts, JH Van Der Wiel… - Journal of Physics …, 2002 - iopscience.iop.org
We report measurements on gas–liquid phase-separating colloid–polymer mixtures. A
horizontally placed optical microscope with long-working-distance objectives enables us to …

Convection-driven phase segregation of deeply quenched liquid mixtures

R Mauri, F Califano, E Calvi, R Gupta… - The Journal of chemical …, 2003 - pubs.aip.org
Observing the phase separation of deeply quenched, low viscosity liquid mixtures we
inferred that the process is driven by the convection due to capillary forces, and not by …

Spinodal decomposition in a model colloid-polymer mixture in microgravity

We study phase separation in a deeply quenched colloid-polymer mixture in microgravity on
the International Space Station using small-angle light scattering and direct imaging. We …

Nucleation and spinodal decomposition of liquid mixtures

AG Lamorgese, R Mauri - Physics of Fluids, 2005 - pubs.aip.org
We simulated the phase segregation of a metastable deeply quenched binary mixture. Our
theoretical approach follows the diffuse interface model, where convection and diffusion are …

Mixing of macroscopically quiescent liquid mixtures

AG Lamorgese, R Mauri - Physics of Fluids, 2006 - pubs.aip.org
We simulate the mixing process of a quiescent binary mixture that is instantaneously brought
from the two to the one-phase region of its phase diagram. Our theoretical approach follows …

Confocal scanning laser microscopy on fluid–fluid demixing colloid–polymer mixtures

D Aarts, HNW Lekkerkerker - Journal of Physics: Condensed …, 2004 - iopscience.iop.org

Equilibrium and nonequilibrium fluctuations at the interface between two fluid phases

P Cicuta, A Vailati, M Giglio - Physical Review E, 2000 - APS
We have performed small-angle light-scattering measurements of the static structure factor
of a critical binary mixture undergoing diffusive partial remixing. An uncommon scattering …

Matching macroscopic properties of binary fluids to the interactions of dissipative particle dynamics

W Dzwinel, DA Yuen - International Journal of Modern Physics C, 2000 - World Scientific
We investigate the role played by conservative forces in dissipative particle dynamics (DPD)
simulation of single-component and binary fluids. We employ equations from kinetic theory …

Phase separation dynamics in colloid–polymer mixtures: the effect of interaction range

I Zhang, CP Royall, MA Faers, P Bartlett - Soft Matter, 2013 - pubs.rsc.org
Colloid–polymer mixtures may undergo either fluid–fluid phase separation or gelation. This
depends on the depth of the quench (polymer concentration) and the polymer–colloid size …
