Active particles in tunable compressible environments
Venkata Manikantha Sai Ganesh Tanuku, Isha Malhotra, Lorenzo Caprini +3
Active particles affect their environment as much as the environment affects their active motion. Here, we present an experimental system where both can be simultaneously adjusted…
Accessing the Free Expansion of a Crystalline Colloidal Drop by Optical Experiments
Marcus Witt, G. H. Philipp Nguyen, Josefine R. von Puttkamer-Luerssen +8
We study poly-crystalline spherical drops of an aqueous suspension of highly charged colloidal spheres exposed to a colloid-free aqueous environment. Crystal contours were obtained…
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…
Writing in Water
Nadir Möller, Lukas Hecht, Ran Niu +2
Writing is an ancient communication technique dating back at least 30,000 years. While even sophisticated contemporary writing techniques hinge on solid surfaces for engraving or t…
Island Hopping of active colloids
Venkata Manikantha Sai Ganesh Tanuku, Peter Vogel, Thomas Palberg +1
Individual self-propelled colloidal particles, like active Brownian particles (ABP) or run-and-tumble swimmers (RT), exhibit characteristic and well-known motion patterns. However,…
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…
