Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

open access: yesAdvanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

Mass‐Manufactured Gradient Plasmonic Metasurfaces for Enhanced Mid‐IR Spectrochemical Analysis of Complex Biofluids

open access: yesAdvanced Materials, EarlyView.
This article presents a surface‐enhanced infrared absorption spectroscopy (SEIRAS) platform using mass‐manufactured gradient plasmonic metasurfaces, overcoming limitations in analyzing real‐world biosamples. The technology achieves 20‐fold signal enhancement and demonstrates superior molecular fingerprinting capabilities.

Overcoming Material Incompatibility via 2D Free‐Surface Engineering

open access: yesAdvanced Materials, EarlyView.
A scalable post‐epitaxial strategy introduces a sub‐nanometric 2D free surface (2DFS) at the heterointerface, effectively decoupling lattice‐mismatched layers. This process significantly reduces strain‐driven defects and dislocation density in Ge/Si heterostructures. The resulting bulk‐like material quality, validated by advanced microscopy and optical

Synthetic Chromatophores for Color and Pattern Morphing Skins

open access: yesAdvanced Materials, EarlyView.
Cephalopods use chromatophore organs (muscle‐actuated pigment sacs) to alter their skin color and pattern. Synthetic chromatophores, which closely mimic the mechano‐optical process found in cephalopods using stimuli‐responsive microscale hydrogel actuators, are reported.

Spiro‐Phenothiazine Hole‐Transporting Materials: Unlocking Stability and Scalability in Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Fluorene‐functionalized spiro‐phenothiazine (PTZ‐Fl) exhibits strong Li+ affinity and thermal stability, enabling a PCE of 25.75% in small‐area cells and 22.07% in 25 cm2 modules. Under ISOS‐L3 conditions, PTZ‐Flbased devices retain over 80% efficiency after 1000 hours, demonstrating superior stability and scalability compared to spiro‐OMeTAD for next ...
