In Situ Polymerization Controlled Growth of Perovskite via Benzoic Acid Crosslinking Agent for Highly Efficient and Mechanically Robust Flexible Perovskite Solar Cell

open access: yesAdvanced Science, EarlyView.
This study proposes a novel strategy to improve the performance of perovskite solar cells through the incorporation of the crosslinking agent 4‐HBA into the perovskite layer. The multifunctional properties of 4‐HBA contribute to power conversion efficiencies of 24.76% for rigid devices and 22.73% for flexible devices, both exhibiting remarkable ...

Mechanisms of In Situ Growth of (Fe4Al3Cr)0.25TiO5 Whisker Driven by Oxygen Partial Pressure and Reinforced Mechanical Properties in Corundum‐Type Medium‐Entropy Oxides

open access: yesAdvanced Science, EarlyView.
In corundum‐type medium‐entropy oxides, oxygen partial pressure regulation facilitated the in situ growth of whiskers, significantly enhancing mechanical properties. The growth mechanism and reinforcing effects of whiskers are systematically elucidated through a combination of theoretical calculations and experimental validation, providing a novel ...

Synergistic Photomagnetic and Photomechanical Dynamics in a Dysprosium‐Based Smart Molecule

open access: yesAdvanced Science, EarlyView.
Photoactive 9‐anthracenecarboxylic acid integrates into a Dy(III) complex enables dual light‐response. UV irradiation triggers anthracene [4+4] cycloaddition, driving a single‐crystal‐to‐single‐crystal transformation to coordination polymer 1A.

Energy localisation and frequency analysis in the locust ear [PDF]

open access: yes, 2013
Animal ears are exquisitely adapted to capture sound energy and perform signal analysis. Studying the ear of the locust, we show how frequency signal analysis can be performed solely by using the structural features of the tympanum.

Efficient Exothermic Press toward Ultrafast and Scalable Manufacturing of Complex Polymer Composites

open access: yesAdvanced Science, EarlyView.
Exo‐press frontal polymerization is a rapid, low‐energy process to produce multiscale fiber‐reinforced polymer composites at high fiber volume fractions. By leveraging localized heat, along with a hybrid monomer system, the reaction front cures parts within a minute and forms a copolymer network.

Inspired by Reinforced‐Concrete Structures: High‐Strength, Stable, Sustainable Reed‐Based Plastics

open access: yesAdvanced Science, EarlyView.
Inspired by the structure of reinforced concrete, which develops a composite with high‐strength, stability, fire resistance, and nontoxicity, by using the regular and continuous of reed fiber and thermoset tannin‐based resin. This composite demonstrates potential as a sustainable alternative to conventional petroleum‐derived plastics, with promising ...
