Modulating D33 Coefficients Through In Situ AgF and Ag2O Growth in PVDF Composites for High‐Performance Piezoelectric Nanogenerators

Advanced Materials Technologies, EarlyView.
In situ, nanoparticle doping enhances the piezoelectric coefficient (**d₃₃**) of PVDF to ≈12 pC/N, while in situ growth of AgF and Ag₂O dopants increases β‐phase concentration. The nanogenerator achieves a 35 V open‐circuit voltage and 1.6 µA short‐circuit current, powering 10 blue LEDs and charging a 50 nF capacitor within 10 s.

Piezoelectric Polyurethane/Barium Titanate Composites with High Stretchability and Voltage Output for Energy Harvesting in Soft Wearable Electronics

Advanced Materials Technologies, EarlyView.
Piezoelectric additives are combined with an elastomer host, creating a material with properties of both parent materials: high voltage output and exceptional stretchability. These stretchable piezoelectric materials have the robustness for integration into soft wearable electronics, functioning as renewable energy harvesters to charge capacitors.

Emerging Ta4C3 and Mo2Ti2C3 MXene Nanosheets for Ultrafast Photonics

Advanced Optical Materials, EarlyView.
The present study reports on the ultrafast nonlinear optical (NLO) response and carrier dynamics of two kinds of MXenes, namely Ta4C3Tx and ordered‐phase Mo2Ti2C3Tx. The Mo2Ti2C3Tx MXene is found to exhibit superior NLO response, surpassing all previously studied MXenes and other 2D nanomaterials.

All‐Optically Driven Optofluidic Light Modulator

Advanced Optical Materials, EarlyView.
In this work, an all‐optically driven optofluidic light modulator is developed, based on the optical actuation of waveguided beams by liquid crystals confined in a microfluidic channel. The photovoltaic effect in lithium niobate is employed to control the alignment of the liquid crystal in the microfluidic channel underneath by a light‐induced electric

Ultrafast Anisotropic Optical‐Gap Shift in Low‐Symmetry Layered GeS

Advanced Optical Materials, EarlyView.
This study reveals ultrafast, anisotropic optical‐gap shift dynamics in GeS. Optical excitation induces a significant redshift in the polarization along the zigzag direction, about three times greater than that along the perpendicular armchair direction.
