Porous crystals in charged sphere suspensions by aggregate-driven phase separation
Nina Lorenz, Christopher Wittenberg, Thomas Palberg
The kinetics of phase transition processes often governs the resulting material microstruc-ture. Using optical microscopy, we here investigate the formation and stabilization of a…
Microstructural diversity, nucleation paths and phase behaviour in binary mixtures of charged colloidal spheres
Nina Lorenz, Ishan Gupta, Thomas Palberg
We study low-salt, binary aqueous suspensions of charged colloidal spheres of size ratio Phi = 0.57, number densities below the eutectic number density n_E, and number fractions of…
To make a glass - avoid the crystal
Thomas Palberg, Eckhard Bartsch, Richard Beyer +5
Colloidal model systems allow for a flexible tuning of particle sizes, particle spacings and mutual interactions at constant temperature. Colloidal suspensions typically crystalliz…
Melting and Freezing Lines for a Mixture of Charged Colloidal Spheres with Spindle-Type Phase Diagram
Nina J. Lorenz, Thomas Palberg
We have measured the phase behavior of a binary mixture of like-charged colloidal spheres with a size ratio of 0.9 and a charge ratio of 0.96 as a function of particle number densi…
Complete description of re-entrant phase behaviour in a charge variable colloidal model system
Patrick Wette, Ina Klassen, Dirk Holland-Moritz +6
In titration experiments with NaOH we have determined the full phase diagram of charged colloidal spheres in dependence on the particle density n, the particle effective charge Zef…
Phase behavior of a deionized binary mixture of charged spheres in the presence of gravity
Nina J. Lorenz, Hans Joachim Schoepe, Thomas Palberg
We report on the phase behavior of an aqueous binary charged sphere suspension under exhaustively deionized conditions as a function of number fraction of small particles p and tot…
