Synthetic paracrine signaling of colloids drives self-assembly limit cycles
Tim E. Veenstra, René van Roij, Pepijn G. Moerman +1
Developing synthetic materials that exhibit life-like behavior, such as internally driven cycles, remains a central challenge in active matter. Here, we introduce a minimal colloid…
Many-body attractions do not stabilize gas-liquid phase separation in aqueous dispersions of charged colloids within the Poisson-Boltzmann framework
Thijs ter Rele, René van Roij, Marjolein Dijkstra
Attractive three-body interactions have been reported for like-charged colloids in low-salt suspensions, based on both finite-element Poisson-Boltzmann calculations and direct expe…
Machine-Learned Many-Body Potentials for Charged Colloids reveal Gas-Liquid Spinodal Instabilities only in the strong-coupling regime of Primitive Models
Thijs ter Rele, René van Roij, Marjolein Dijkstra
Past experimental observations of gas-liquid and gas-crystal coexistence in low-salinity suspensions of highly charged colloids have suggested the existence of like-charge attracti…
Multimodal Physical Learning in Brain-Inspired Iontronic Networks
Monica Conte, René van Roij, Marjolein Dijkstra
Inspired by the brain, we present a physical alternative to traditional digital neural networks -- a microfluidic network in which nodes are connected by conical, electrolyte-fille…
Counting, Computing, and Pattern Recognition with Self-Assembling Non-Reciprocal DNA Tiles
Tim E. Veenstra, René van Roij, Marjolein Dijkstra
Harnessing the intrinsic dynamics of physical systems for information processing opens new avenues for computation embodied in matter. Using simulations of a model system, we show…
Free Minimization of the Fundamental Measure Theory Functional: Freezing of Parallel Hard Squares and Cubes
S. Belli, M. Dijkstra, R. van Roij
Due to remarkable advances in colloid synthesis techniques, systems of squares and cubes, once an academic abstraction for theorists and simulators, are nowadays an experimental re…
Polydispersity stabilizes Biaxial Nematic Liquid Crystals
S. Belli, A. Patti, M. Dijkstra +1
Inspired by the observations of a remarkably stable biaxial nematic phase [E.v.d. Pol et al., Phys. Rev. Lett. 103, 258301 (2009)], we investigate the effect of size polydispersity…
Phase diagram and effective shape of semi-flexible colloidal rods and biopolymers
Matthew Dennison, Marjolein Dijkstra, Rene van Roij
We study suspensions of semi-flexible colloidal rods and biopolymers using an Onsager-type second-virial functional for a segmented-chain model. For suspensions of thin and thick f…
