Synthetic paracrine signaling of colloids drives self-assembly limit cycles
Tim E. Veenstra, René van Roij, René van Roij +2
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…
Nonlinear iontronic signal processing with neuromorphic Spike Rate-Dependent Plasticity
T. M. Kamsma, Y. Gu, D. Shi +4
We present an integrated iontronic memristor circuit that reproduces biologically inspired Spike Rate-Dependent Plasticity (SRDP) and functions as a physical nonlinear frequency ke…
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…
