Research Objectives: Simulation of soft-condensed matter systems and complex fluids, mostly driven by electrostatics (colloids, polyelectrolytes, hydrogels, …).
Approach: Monte Carlo and molecular dynamics techniques of particle-based, coarse-grained models.
Significant Results:
• Triblock copolymer solutions1 have been shown to form thermoreversible gels at remarkably low concentrations. Their dynamical properties exhibit a strong similarity to high-density glass-forming materials.
Broader Impact: • The model calculations lead to an improved understanding of hydrogel formation. Hydrogels have important biomedical applications, including drug-delivery devices.
Outreach: Luijten organized an MCC/CECAM sponsored workshop on “Novel Simulation Methods for Soft Condensed Matter Systems” (Lyon, June 2004).
