Adaptive Twisting Metamaterials

open access: yesAdvanced Materials, EarlyView.
This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.

Magnetic Domain Texture in Fe3O4 Thin Films on SiO2 Nanospheres

open access: yesAdvanced Materials, EarlyView.
Fe3O4 thin films grown on ordered SiO2 nanospheres form curved nanocaps with 3D geometry, inducing magnetic domain texture. X‐ray spectromicroscopy (XMCD‐PEEM), cross‐sectional electron microscopy (STEM), and polarized grazing‐incidence small‐angle neutron scattering (GISANS) reveal how topography modulates magnetization.

Nanoconfined Cu─O─Mo Asymmetric Sites Enable Ambient Spontaneous O2‐to‐1O2 Conversion for Sustainable Water Purification

open access: yesAdvanced Materials, EarlyView.
An asymmetric Cu+─O─Mo6+ dual‐site in a nanoconfined membrane turns O2 into singlet oxygen at ambient conditions with ≈95% selectivity, bypassing superoxide. It concentrates reactants for rapid pollutant removal, operates stably in continuous flow with ultra‐low metal leaching and cost, efficiently purifying complex waters.

A Kinetic Monte Carlo Model to Understand Limiting Regimes of Photocurrent and Interfacial Charge Transfer in Organic Semiconductor–Electrolyte Interfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
The interface between a conjugated polymer and phosphate buffer saline is modeled by employing multiphysics kinetic Monte Carlo simulation. Results demonstrate that the Marcus Gerischer theory is inadequate, and particle‐based simulation with molecular Marcus theory is required for accurate modeling.

Boosting the Transparency of Metallic SrNbO3 Through Ti Doping

open access: yesAdvanced Materials Interfaces, EarlyView.
Transparent conductors are optoelectronic devices of high demand. The present study presents a path on how to boost the figure of merit of the recently proposed perovskite oxides: Ti doping reduces electronic correlations and thus the absorption above the plasma frequency, while keeping the plasma frequency below the visible range.
