Oxygen Evolution Electrocatalysts with Trinuclear, Mixed‐Valence Iron Motifs on Electronically Aligned Carbon Dots

open access: yesAdvanced Functional Materials, EarlyView.
Trinuclear iron oxo‐bridged catalytic ensembles stabilized by aspartic‐acid‐derived carbon dots provide an effective platform for alkaline oxygen evolution. Mixed‐valence charge balancing, inner‐sphere charge transport, and work‐function alignment within the N/O‐rich carbon framework promote cooperative Fe‐site chemistry and efficient OER ...

Poisson's Ratio‐Driven Control of Myogenic Differentiation and Maturation in Auxetic Metamaterials under Dynamic Mechanical Stimulation

open access: yesAdvanced Functional Materials, EarlyView.
This study explored how innovative “auxetic” scaffolds, which expand when stretched, influence skeletal muscle development. Researchers cultured muscle cells on different scaffold designs and applied repeated stretching over 10 days. They found that scaffold geometry affected muscle cell differentiation and fiber formation.

A novel hybrid interlinking transformer-integrated DFIG wind power and energy storage system with flexible control strategy

open access: yesInternational Journal of Electrical Power & Energy Systems
Double-fed induction generator (DFIG) based wind turbine generator (WTG) demonstrates pronounced sensitivity to the abnormal grid voltages, such as sag, swell or harmonic, which can precipitate disconnections from the power grid due to fault ride-through

Hydrogel‐Based Method for High‐Resolution Measurements of Contact Mechanics in Rapid Biological Adhesives: A Case Study in Cuttlefish Tentacle Strikes

open access: yesAdvanced Functional Materials, EarlyView.
Cuttlefish and squid can catch their prey within milliseconds using specialized tentacles and suckers. The physics of how the suckers can attach so quickly has remained a mystery given the technical challenges of studying them in vivo. In this publication, we develop a hydrogel that retains imprints of the suckers in order to estimate the forces they ...

Multi‐Energy Coupling in Hierarchical Textiles for Photo‐Thermal‐Electric Conversion

open access: yesAdvanced Functional Materials, EarlyView.
This study develops a V‐shaped sandwich evaporator via hierarchical heat‐flow management to resolve constraints on energy utilization and heat allocation in solar evaporation‐thermoelectric systems. The device achieves an evaporation rate of 2.18 kg m−2 h−1 and a peak power density of 224.15 mW m−2, providing an effective strategy for off‐grid solar ...
