Multi‐Force‐Driven Self‐Recoverable SWIR Mechanoluminescence for Underwater Communication

Advanced Science, EarlyView.
This study represents the first demonstration of self‐recoverable mechanoluminescent (ML) within a single material across diverse mechanical modes, enabled by the synergistic coupling of piezoelectric and triboelectric effects. Through a combinatorial doping approach, the MgNb2O6 crystal exhibits breakthrough short‐wavelength infrared ML performance ...

Bimodal Mechanoluminescence Enables Multicolor Luminescent Tailing for Ultra‐Accurate Loading Speed Visualization and Detection

Advanced Science, EarlyView.
MgF2 exhibits a speed‐dependent mechanoluminescence (ML) color distribution arising from distinct ML lifetimes, showing blue emission under slow sliding and multicolor emission under fast sliding. A promising method for evaluating ML lifetime is proposed based on the trailing effect. By synergistically integrating instantaneous and persistent ML with a

Conformation‐Modulated Lignin for Durable and High‐Output Cellulosic Triboelectric Materials Toward Self‐Powered Sensing

Advanced Science, EarlyView.
Conformation‐engineered alkali lignin with flexible aliphatic side chains is integrated into cellulose to suppress tribo‐induced fiber fibrillation and interfacial wear. Dynamic chain adaptability enhances frictional energy dissipation and dielectric polarization, enabling durable, high‐output triboelectric sensing with excellent recyclability and ...

Improving the Thermoelectric Properties of Conjugated Polymer Thin Films by Dip Coating – but not through Alignment

Advanced Electronic Materials, EarlyView.
The study demonstrates that dip coating at lower speeds significantly enhances the thermoelectric performance of P3HT by improving electrical conductivity. Contrary to expectations, this improvement is seemingly not due to polymer alignment but rather to better structural order achieved during slower solvent evaporation at lower dip coating speeds ...

Tunable Electronic and Optoelectronic Properties of MoS2 Through Molecular Coverage‐Controlled Polyoxometalate Doping

Advanced Electronic Materials, EarlyView.
Molecular charge transfer at the V12‐DyPc/MoS2 interface stabilizes trions, suppressing neutral A‐exciton emission and enabling controlled modulation of the A–‐trion population, bridging excitonic physics with polyoxometalate charge‐transport functionality.
