Salt-induced changes of colloidal interactions in critical mixtures
Ursula Nellen, Julian Dietrich, Laurent Helden +4
We report on salt-dependent interaction potentials of a single charged particle suspended in a binary liquid mixture above a charged wall. For symmetric boundary conditions (BC) we…

Tunability of Critical Casimir Interactions by Boundary Conditions
Ursula Nellen, Laurent Helden, Clemens Bechinger
We experimentally demonstrate that critical Casimir forces in colloidal systems can be continuously tuned by the choice of boundary conditions. The interaction potential of a collo…
