Electron Extraction Optimization for Carbon‐Based Hole‐Conductor‐Free Perovskite Photovoltaics With Record 1.41 V VOC

Advanced Materials, EarlyView.
A gradient electron energy level strategy is constructed to reduce voltage losses in planar HTL‐free CsPbI2Br C‐PSCs. This electron extraction optimization enables rapid photogenerated electron extraction and carrier separation, thereby suppressing recombination at the back contact. The resulting PSCs deliver a record VOC of 1.41 V, a high PCE of 17.42%

Artesunate Nanoplatform Targets the Serine–MAPK Axis in Cancer‐Associated Fibroblasts to Reverse Photothermal Resistance in Triple‐Negative Breast Cancer

Advanced Materials, EarlyView.
The artesunate nanoplatform selectively targets ECM CAF, functioning as a GTPase inhibitor through disruption of intracellular serine homeostasis. This metabolic intervention effectively suppresses MAPK cascade activity, which consequently inhibits PTT‐induced CAF to ECM CAF differentiation.

Spin‐State Manipulation of Atomic Manganese Center by Phosphide‐Support Interactions for Enhanced Oxygen Reduction

Advanced Materials, EarlyView.
The electronic configuration of Mn single‐atom sites is regulated from low‐spin to high‐spin states by embedding well‐defined molybdenum phosphide nanocrystals nearby (MoP@MnSAC‐NC). The electronic phosphide‐support interaction between MoP and Mn single atoms drives the electronic structure transition in Mn sites from low‐spin to high‐spin states, and ...

High‐Performance Phototransistor Based on a 2D Polybenzimidazole Polymer

Advanced Materials, EarlyView.
A crystalline 2D polybenzimidazole polymer (2DPBI), incorporating a porphyrin‐based π‐system linked via 1,3‐diazole units, is synthesized on the water surface over large areas. The 2DPBI thin‐film exhibits high charge carrier mobility (≈240 cm2 V−1 s−1, measured by terahertz spectroscopy), strong photoresponse, and band‐like transport, enabling ...

Spatially Resolved Observation of Ferroelectric‐to‐Paraelectric Phase Transition in a Two‐Dimensional Halide Perovskite

Advanced Materials, EarlyView.
Temperature‐dependent nanoscale ferroelectric domain evolution and the ferroelectric‐to‐paraelectric phase transition in 2D halide perovskites is visualized using piezoresponse force microscopy. The phase transition initiates locally below the Curie temperature and progressively propagates as paraelectric regions expand.
