Tracing the Dynamic Chemical Transformations of Spiro‐OMeTAD in Operating Perovskite Solar Cells

Advanced Science, EarlyView.
Mapping of Spiro‐OMeTAD layer's chemistry and electronic properties in PSC: Advanced cluster ion‐beam sputtering depth profile XPS reveals that environmental stressors (light, potential, and moisture) trigger the decomposition of LiTFSI dopants in Spiro‐OMeTAD.

Nanoplastics and Neurodegeneration: A Roadmap From Mechanism to Causation

Advanced Science, EarlyView.
Nanoplastics are pervasive environmental contaminants with potentially profound implications for human health. Emerging evidence suggests a possible link between nanoplastic exposure and neurodegeneration, a key driver of ageing and dementia, yet causality remains unresolved.

Bidirectional Photoswitching of a Tailored Azobenzene with Red and Far‐Red Light Involving Triplet Sensitization in an Aqueous System

Advanced Science, EarlyView.
The action spectrum of a tailored azobenzene is shifted toward bio‐optical window through the chemical modification of its singlet and triplet energy levels. Consequently, the bidirectional photo‐switching of azobenzene in physiological conditions is achieved when excited by red and far‐red light, which offers greater tissue penetration.

Synaptic κ‐Ga2O3 Photodetectors for Privacy‐Enhancing Neuromorphic Computing

Advanced Science, EarlyView.
We report on a single‐element neuromorphic sensor based on the persistent photoconductivity (PPC) of κ‐phase Ga2O3 capable of sensing ultraviolet light and harnessing intrinsic data privacy. The approach establishes a materials‐enabled pathway toward compact, intelligent, and privacy‐enhancing optoelectronic hardware for next‐generation edge systems ...

Defect‐Functionalization‐Mediated Tunneling Drives Nonlinear Photoemission in Perovskites

Advanced Science, EarlyView.
This cover illustration depicts CsPbBr3 perovskite nanocrystals embedded with functionalized defect vacancies, where electrons migrate through defect‐mediated pathways and emit as lightning‐like beams. The imagery visualizes the core discovery of our work—defect‐functionalization‐mediated tunneling enabling nonlinear photoemission, where deep‐level ...

Ultrabroadband and Highly Sensitive Short‐Wave Infrared Molecular Fingerprinting via Acoustic MXene Plasmons

Advanced Science, EarlyView.
Acoustic plasmons in Ti3C2Tx MXene strongly compress infrared electromagnetic fields and enhance light–matter interactions at the nanoscale. This platform couples broadband plasmon excitations with molecular vibrations, enabling simultaneous sensing of high‐ and low‐frequency vibrational modes in ultrathin PMMA and graphene oxide films, and extending ...
