Summary: The development of biodegradable plastic materials is crucial in addressing environmental and health issues associated with plastic waste accumulation. A biodegradable composite material based on hydroxyethyl cellulose polymer and tyrosine nanocrystals has been successfully fabricated, demonstrating enhanced strength and ductility. The assembly pattern and strong interactions between components contribute to this emergent behavior. Water-resistant biodegradable composites were also created with a hydrophobic polycaprolactone protection layer.

Summary: This study introduces a three-component self-assembly system where the individual components do not interact with each other, but combine to form a new supramolecular structure during crystallization. This emergent behavior is characterized by the formation of an all-hydrocarbon capsule containing iodine, showcasing unique properties beyond simple sum-of-the-components analysis.

Summary: The emerging field of passive macro-scale tile-based self-assembly (TBSA) shows promise in enabling effective manufacturing processes. A framework is proposed that utilizes magnetically-bonded tiles to increase stability as the assembly grows. The proposed approach has self-stabilizing characteristics and allows for the construction of assemblies containing hundreds of tiles.

Summary: The ability of cells to sense and respond to geometric cues remains poorly understood, especially how cells sense and communicate their shape. Septins, GTP-binding proteins, localize to sites of micrometer-scale membrane curvature, but it is unknown how these steps lead to curvature sensing. Experimental and modeling results indicate that curvature preference of septins is not absolute but rather sensitive to the combinations of membrane curvatures present in a reaction. This study provides insight into the emergent property of curvature sensing and how it can be modulated by changing physicochemical and geometric parameters involved in septin assembly.

Summary: This article investigates the self-assembly behavior of droplet swarms and its feedback effect on droplet generation in a step-emulsification microdevice using a high-speed camera. The study reveals that the self-assembly of droplet swarms is controlled by various factors, and weakening the feedback is beneficial for improving the monodispersity of droplets.

Summary: In this study, machine-guided discovery of emergent morphologies from a cylinder/lamellae block copolymer blend directed by a chemical grating template was demonstrated without direct human intervention on a synchrotron x-ray scattering beamline. This approach enables mapping of the morphology-template phase space in less time than manual characterization, and highlights regions that warrant further investigation. The results reveal localized, template-directed partitioning of coexisting lamella- and cylinder-like subdomains at the template period length scale, resulting in previously unknown morphologies such as aligned alternating subdomains, bilayers, or a ladder morphology. This work emphasizes the crucial role that autonomous characterization can play in advancing the paradigm of directed self-assembly (DSA).

Summary: This study reports a self-assembled multiferroic heterostructure, where the spontaneous organization of ferroelectric polarization and the formation mechanism of the structure are investigated using atomic-scale electron microscopy and theoretical calculations. The results suggest the possibilities of generating and controlling multiferroic self-assembled systems, which may provide a basis for engineering novel materials with emergent properties.

Summary: The study explores the collective behavior of colloidal particles in a non-equilibrium system, with a focus on the influence of external and interparticle forces, including hydrodynamic forces which are often overlooked. Experiment and simulation results show that the particles interact hydrodynamically in a rotating cylindrical cell, forming different structures and evolving based on gravity forces. The findings suggest that the rotation scheme plays a crucial role in determining the aggregation and motion of colloidal particles.

Summary: Confinement has significant effects on the collective dynamics of active systems. In a modeled active system in circular confinement, biased active particles can spontaneously form a spiral vortex near the boundary with nonmonotonic dependencies on the biased angle and the strength of the anisotropic interaction. This work provides insights into dynamic behaviors and designing ordered collective behaviors.

Summary: Synchronized oscillations are a common phenomenon in all living systems, involving delay response and communication among entities. In social spiders, individuals synchronize their movements to catch large prey. An experimental mechanistic model reveals that the emergence of oscillations involves a variable refractory period, depending on the intensity of prey and conspecific signals. The benefits of synchronization outweigh the cost of delayed immobility phases.
