The reentrant condensation of polyelectrolytes induced by diluted multivalent salts: A mean-field level revisiting
Huaisong Yong, Bilin Zhuang, Sissi de Beer
We study the reentrant condensation of polyelectrolytes in dilute solutions of small multivalent salts, whose phase-transition mechanism remains poorly understood. Motivated by rec…
Non-equilibrium configurations of swelling polymer brush layers induced by spreading drops of weakly volatile oil
Özlem Kap, Simon Hartmann, Harmen Hoek +4
Polymer brush layers are responsive materials that swell in contact with good solvents and their vapors. We deposit drops of an almost completely wetting volatile oil onto an oleop…
Dramatic effect of fluid chemistry on cornstarch suspensions: linking particle interactions to macroscopic rheology
Loreto Oyarte Galvez, Sissi de Beer, Devaraj van der Meer +1
Suspensions of cornstarch in water exhibit strong dynamic shear-thickening. We show that partly replacing water by ethanol strongly alters the suspension rheology. We perform stead…
