Advanced Science, EarlyView.Complex microarchitectures emerge from simple flow‐driven transformations as static mixers iteratively reorient and split material domains. Coupled with diverse deposition strategies, chaotic printing provides an accessible platform for fabricating architected materials that support biologically and chemically relevant processes. ABSTRACT Nature builds

Tunable Oxygen Connectivity in Carbaporphyrinoid Polymers on Metal Surfaces
Angewandte Chemie, EarlyView.Hydroxyl‐functionalized dicarbaporphyrinoid polymers synthesized on Au(111) enable tunable oxygen‐mediated connectivity under UHV conditions. Thermal activation yields one‐dimensional hydroxyl‐terminated polymers that can selectively evolve into either covalently‐linked dibenzo‐p‐dioxane architectures through intermolecular C–O–C coupling or two‐fold ...

Visible‐Light‐Mediated Lewis Acid‐Catalyzed Diradical Hydrogen Atom Transfer Reaction of Enamides
Advanced Science, EarlyView.The Lewis acid catalysis was crucial for the success of the DHAT reaction of enamides by lowering the energy of the triplet excited state and modulating the reactivity of the formed diradical intermediate in a carbon‐to‐carbon 1,5‐DHAT and consequent cyclization that allows the functionalization of C(sp3)−H bonds to construct a variety of novel β ...

MOF‐Derived Cu‐TiO2/Alginate Micromotors for Buoyancy‐Regulated 3D Motion
Advanced Science, EarlyView.In this work, cyanobacteria‐inspired sodium alginate (SA)/Cu‐TiO2/Fe3O4 hydrogel micromotors generate and encapsulate O2 microvesicles upon light irradiation, enabling buoyancy‐mediated Z‐axis upward migration and surface enrichment at the light‐exposed water‐air surface.

Abstract Representation of Movement Parameters in Basal Ganglia Output
Advanced Science, EarlyView.The basal ganglia output provides a scalable velocity/position signal across behavioral contexts, supporting the idea that these variables are represented in the brain as abstract entities rather than as fixed changes in joint angles or specific sets of body effectors.

Advanced Science, EarlyView.Launching structures for in‐plane hyperbolic polaritons in α‐MoO3 are optically programmed through already deposited flakes into the phase‐change material In3SbTe2. Precise alignment with the flake's crystal axes, focusing of polaritons by an optically programmed disk, and a first experimental realization toward a nanocavity for in‐plane hyperbolic ...

SPICE‐Compatible Compact Modeling of Cuprate‐Based Memristors Across a Wide Temperature Range
Advanced Electronic Materials, EarlyView.A physics‐guided compact model for YBCO memristors is introduced, incorporating carrier trapping, field‐induced detrapping, and a differential balance equation to describe their switching dynamics. The model is compared with experiments and implemented in LTspice, allowing realistic circuit‐level simulations.
