Precise Microstructural and Stoichiometric Control Advances Flexible Ag2Te Thin‐Film Thermoelectrics for Wearable Energy Harvesting

Advanced Materials, EarlyView.
Flexible Ag2Te thin films achieving a record‐high mobility of 4756 cm2 V−1 s−1 and a peak power factor of 18.5 µW cm−1 K−2 are developed via precise structural control. The assembled flexible devices demonstrate excellent mechanical stability and ultrafast voltage response, enabling precise thermal detection when integrated into a robotic gripper for ...

Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Integrating ZnO/Ag2O@g‐C3N4‐Based Nanocomposites Into a Carrageenan Matrix to Efficiently Remove Heavy Metals From Water

Advanced Materials Interfaces, EarlyView.
ABSTRACT This research focused on characterizing graphitic carbon nitride (g‐C3N4) nanocomposites incorporated with ZnO and Ag2O nanoparticles, and carrageenan to remove heavy metals. The ZnO/Ag2O@ g‐C3N4 and ZnO/Ag2O/g‐C3N4@Carr nanocomposites demonstrated thermal stability of 97.40% (108.81°C) and 82.80% (188.99°C) for TGA.

Nitric Oxide‐Generating Poly (allylamine hydrochloride) Coating on Biomedical Titanium Implant

Advanced Materials Interfaces, EarlyView.
We report a metal‐free, nitric oxide (NO)‐generating coating in which poly(allylamine hydrochloride) (PAH) is covalently immobilized onto titanium. The coating catalyzes NO generation from the endogenous S‐nitrosothiol GSNO, retains activity after multiple reuse cycles and pH exposures, and maintains endothelial cell viability while modulating ...

Passivated SiC Surfaces for Photonic and Quantum Applications: Balancing Chemical Stability and Surface Luminescence

Advanced Materials Interfaces, EarlyView.
Low‐temperature passivation of SiC reveals that optical surface quality and chemical stability are not directly correlated. Ar plasma‐treated and SiNx‐passivated surfaces yield the lowest photoluminescence background, whereas CF4 plasma and ALD‐grown dielectrics introduce higher emission.

Pattern Formation in Non‐Equilibrium Architected Materials

Advanced Materials Technologies, EarlyView.
This article demonstrates an artificial mechanical system ‐ a robotic metamaterial ‐ as an accessible and versatile platform within which to explore and prescribe the reaction‐diffusion driven pattern formation hitherto associated with comparatively less accessible and versatile non‐equilibrium biological and chemical systems.

Advanced Design for Weakly Coupled Resonators by Automatic Active Optimization

Advanced Materials Technologies, EarlyView.
An Automatic Active Optimization (AAO) strategy integrates machine learning predictors and genetic algorithms in a closed‐loop workflow. By iteratively expanding its dataset with new discoveries, AAO overcomes the limits of conventional methods. This approach finds superior microstructural designs beyond the initial sample space. We demonstrate this on
