Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

open access: yesAdvanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Ionic Gating of Liquid‐Crystal‐Like Pteridine Assemblies Enables Tunable Light Scattering

open access: yesAdvanced Materials, EarlyView.
Tunable optical properties emerge through developmentally regulated ionic gating, which transforms disordered, ultraviolet (UV)‐absorbing organelles into concentrically ordered, liquid‐crystal‐like light scatterers. By integrating analyses of pteridine composition, potassium‐dependent assembly, hierarchical ultrastructure, and optical behavior, the ...

Microgels Enable iPSCs to Assemble, Expand, and Differentiate Into Organoids—From Sizable to High‐Throughput

open access: yesAdvanced Materials, EarlyView.
A chemically defined PEG‐based microgel platform enables scalable, reproducible production of three‐dimensional microgel‐iPSC constructs in multiple sizes. The system is compatible with high‐throughput automation and supports human iPSC expansion and differentiation within a single construct, including directed differentiation into cardiac organoids ...

A Thermoreversible Gelation Pathway to Plant Cuticle‐Inspired Biopolymer Aerogel Monoliths Based on Network‐Spherulitic Crystal Assemblies

open access: yesAdvanced Materials, EarlyView.
To address functionality limitations in plant‐based and industrially compostable polymer aerogels, this work introduces bio‐inspired aerogels with broadened functionality. Inspired by functional plant tissues, lightweight biopolymer aerogels based on exclusively stereocomplex crystals are fabricated, featuring hierarchically macro‐/meso‐porous ...

Turning Nd‐Fe‐B Swarf Into High‐Value Bulk Feedstocks via Sustainable Hydrogen Plasma: From Rare‐Earth Oxides to Metals and Hydrides

open access: yesAdvanced Materials, EarlyView.
Oxidized Nd‐Fe‐B magnet swarf is transformed into valuable bulk feedstock through a single‐step hydrogen plasma process. The reaction converts complex rare‐earth‐containing waste into separated metallic, oxide, and hydride fractions without acid leaching.

Surface Functionalization Modulates Collective Cell Behavior Near Topological Defects Induced by Topographical Patterning

open access: yesAdvanced Materials Interfaces, EarlyView.
Strongly adhered cells align with concentric circular ridges and exhibit predominantly tangential motion, whereas weakly adhered cells fail to follow topographical guidance and display enhanced radial inward motion. ABSTRACT Living cells establish long‐range orientational order through collective alignment, giving rise to topological defects whose ...

Microscale 3D‐Printed Digital Strain Switches for Embedded Mechanical Computation

open access: yesAdvanced Materials Technologies, EarlyView.
Microscale 3D‐printed strain switches on flexible films convert deformation into native digital signals at geometry defined thresholds. A closed form model predicts switching from 3000 to 15 000 microstrain and is validated across 110 devices. Reliable ohmic closure and strain activated AND, OR, and XOR logic point toward low‐power mechanical ...

Bioinspired Adaptive Artificial Cilia With Tunable Sensitivity and Dynamic Range for Airflow Monitoring in the Central Airway

open access: yesAdvanced Materials Technologies, EarlyView.
A magnetically reconfigurable airflow sensor integrated with an airway stent enables tunable sensitivity and dynamic sensing range. Airflow‐induced cantilever deformation generates resistance changes, while an external magnetic field modulates sensor stiffness, enhancing sensitivity at low airflow velocities and extending the sensing range at higher ...
