Generic theory of colloidal transport
Frank Julicher, Jacques Prost
We discuss the motion of colloidal particles relative to a two component fluid consisting of solvent and solute. Particle motion can result from (i) net body forces on the particle…
Modeling phase behavior for quantifying micro-pervaporation experiments
Michael Schindler, Armand Ajdari
We present a theoretical model for the evolution of mixture concentrations in a micro-pervaporation device, similar to those recently presented experimentally. The described device…
Colloidal stability of tannins: astringency, wine tasting and beyond
D. Zanchi, C. Poulain, P. Konarev +2
Tannin-tannin and tannin-protein interactions in water-ethanol solvent mixtures are studied in the context of red wine tasting. While tannin self-aggregation is relevant for visual…
Non-equilibrium self-assembly of a filament coupled to ATP/GTP hydrolysis
Padinhateeri Ranjith, David Lacoste, Kirone Mallick +1
We study the stochastic dynamics of growth and shrinkage of single actin filaments or microtubules taking into account insertion, removal, and ATP/GTP hydrolysis of subunits. The r…
Mechanical response of active gels
T. B. Liverpool, M. C. Marchetti, J. -F. Joanny +1
We study a model of an active gel of cross-linked semiflexible filaments with additional active linkers such as myosin II clusters. We show that the coupling of the elasticity of t…
Probing thermal waves on the free surface of various media: Surface Fluctuation Specular Reflection Spectroscopy
Astrid Tay, Caroline Thibierge, Danièle Fournier +5
Thermal motion gives rise to fluctuations in free surfaces; the propagation of the thermally excited waves on such surfaces depends on the mechanical properties of the medium. Thei…
