	abstract = {While the principles of Turing-type morphogenesis are central to understanding biological pattern formation, their rational application for the design of synthetic materials remains a significant challenge. To address this gap, we rationally design stationary reaction-diffusion patterns using a chemical reaction network (CRN) of small organic molecules bearing thiol groups - a functional handle ubiquitous in materials chemistry. The CRN features autocatalysis coupled with both rapid direct inhibition and a negative feedback loop. We report the formation of dot, line, and net patterns obtained with the assistance of numerical modeling by adjusting reactant feed rates and concentrations. The use of disulfide-crosslinked polyacrylamide hydrogels enables the modulation of thiol diffusion and subsequent derivatization of the immobilized thiols with dyes, enzymes, and crosslinkers to produce soft materials. This entire process, from out-of-equilibrium self-organization to a patterned soft material, conceptually resembles the biological process that gives rise to skin patterns. Overall, this work establishes a pathway for applying Turing-type self-organization to the structuring of synthetic matter. © 2026. The Author(s).},

Here we experimentally investigate the size-dependent oscillatory collisions, synchronization, and self-assembly of calcium-alginate motors ranging from two to fifteen units. Using high-speed imaging and a particle-based model incorporating pairwise interactions, we reveal that smaller motors sustain longer oscillations, while larger motors coordinate the motion of smaller ones, leading to vibrational-like dynamics. Assemblies of eight or more motors form clusters characterized topologically by Betti numbers, reflecting evolving connectivity and voids. Our findings elucidate how size-dependent forces govern the emergent spatiotemporal patterns and self-organization of active polymer motors, providing insights for designing intelligent collective systems with potential applications in micro-actuation and soft robotics.},

	abstract = {Autocatalysis plays a critical role in the self‐organization of chemical and biological systems, influencing phenomena such as bistability and reaction–diffusion front formation. In the rhizosphere, the regulation of reactive oxygen species (ROS) is mediated by intricate networks of reversible autocatalytic reactions, yet the mechanisms governing their spatiotemporal dynamics remain unclear. Here, we perform comprehensive numerical simulations of a reaction–diffusion model for ROS dynamics incorporating redox couples, sodium borohydride, and oxygen. We identify oxidation‐driven autocatalysis as the primary mechanism responsible for the emergence of stable reaction–diffusion fronts that propagate with constant velocity and shape, whereas reduction fronts display diffusive broadening attenuated by the local oxygen concentration. Furthermore, we demonstrate that reversible quadratic autocatalytic cycles coupled to a simple autocatalyst removal and diffusion are sufficient to reproduce these characteristic front behaviors. These results also provide insights that are transferable to a wide range of autocatalytic networks exhibiting spatiotemporal pattern formation.},

	abstract = {Droplet generators represent a fast-growing area of microfluidics, since each volume of the dispersed phase functions as an individual microreactor, therefore they offer high throughput and reduced sample consumption. By injecting the dispersed phases containing the reactants, the mixing can be tuned separately, thus a higher control over reactions inside the droplets is achievable. The numerical investigation of such multi-phase and multi-component systems proposes various challenges, since the concentrations of species also depend on the distribution of phases. In this article, we investigate the concentration distribution of the species in microfluidic droplet generators both experimentally and theoretically. Besides the characterization of the distribution of the dispersed and continuous phases, we have also studied the effect of injection rates on mixing inside the droplets. The size of the droplets decreases on increasing the flow rate of the oil phase and increases on increasing the flow rate of water phase compared to the oil phase. The numerical analysis based on solving the Navier–Stokes equation with volume-of-fluid method including a diffusive component in the aqueous phase corroborated the experimental findings. Furthermore, by determining the contribution of various transport processes to mixing of reactants inside the dispersed phases, we have shown that convection is dominant inside the droplets for all parameters used. © 2025 The Authors},
