Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

open access: yesAdvanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

Nanodiamond Quantum Sensors for Probing Free Radical Biology

open access: yesAdvanced Functional Materials, EarlyView.
Free radicals play key roles in cellular signaling and disease but remain difficult to measure in living systems. Nanodiamonds (NDs) with nitrogen‐vacancy (NV) centers enable quantum sensing of local magnetic noise via T₁ relaxometry, providing nondestructive radical detection in living cells.

Robust Polymer Hydrogels Improve Electric‐Fish‐Inspired Batteries

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Electric‐fish‐inspired hydrogel batteries based on ion‐concentration gradients offer an attractive route to soft power sources; however, the poor mechanical properties of existing hydrogels limit device assembly and performance. Here, we report poly(ethylene glycol) methyl ether acrylate hydrogels that enable ion‐gradient batteries composed of

Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...

Assembly of Cell‐Seeded 3D Printed Hydrogel Modules with Perfusable Channel Networks

open access: yesAdvanced Functional Materials, EarlyView.
Macroscale assembly was utilized to prepare perfusable tissue constructs from individually 3D printed hydrogel modules with embedded branched channel networks and port arrays for cell seeding. Novel multi‐material bioreactors were fabricated to facilitate the gluing of individual modules and the perfusion culture of assembled modular constructs seeded ...

Chirality and Organization of Adsorbates Modify Surface Phonon Dynamics

open access: yesAdvanced Functional Materials, EarlyView.
Chirality and molecular organization are shown to influence surface phonon dynamics in gold films. Time‐resolved Joule heating measurements reveal that ordered homochiral monolayers increase the Debye temperature and disordered layers reduce it, while ordered racemic controls have no effect.
