Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.

Status and Development Perspectives of the Compressed Air Energy Storage (CAES) Technologies—A Literature Review

Energies
The potential energy of compressed air represents a multi-application source of power. Historically employed to drive certain manufacturing or transportation systems, it became a source of vehicle propulsion in the late 19th century.

Chiral Phase Change Nanomaterials

Advanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Unraveling MXene Oxidation Mechanisms Under Realistic Gas Environments by In Situ Gas‐Cell TEM

Advanced Functional Materials, EarlyView.
Real‐time visualization of MXene degradation reveals a fundamental oxidation mechanism under oxygen and moisture environments. Using in situ gas‐cell electron microscopy, this study demonstrates that oxygen degradation drives a thermodynamically controlled high‐temperature transformation into mixed rutile/anatase phases.
