High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

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.

Autonomous Spatiotemporal Regulation of Reversible Hydrogel Actuators by Chemical Reaction Networks

open access: yesAdvanced Materials, EarlyView.
Hydrogel actuators with reversible response to thiols are developed using reversible binding of thiols to Michael acceptors. Autonomous spatiotemporal regulation of reversible movement of these hydrogels is achieved using thiol‐based chemical reaction networks containing both positive and negative feedback.

Hydrogel Thermostat Inspired by Photoprotective Foliage Using Latent and Radiative Heat Control

open access: yesAdvanced Materials, EarlyView.
Guided by Populus alba foliage, this hydrogel latent‐radiative thermostat (LRT) actively balances latent and radiative heat fluxes. An LRT switches solar reflectance, maintains high mid‐IR emissivity, and reversibly evaporates/regenerates water, while titanium oxide (TiO2) nanoparticles toughen the film.

“Tear‐And‐Stack” Twisted SrTiO3 Moiré Superlattices for Precise Interfacial Reconstruction and Polar Topology

open access: yesAdvanced Materials, EarlyView.
The tear‐and‐stack method enables the creation of twisted SrTiO3 bilayers with accurate twist‐angle control, which yield atomically sharp oxide moiré superlattices with emergent exotic topological polar vortices, thereby opening a new pathway for twistronics based on 2D‐like non‐van der Waals oxides.
