Piezoelectric properties of polymer/lead-free ceramic composites [PDF]

, 2016
Thermoplastic/lead-free piezoelectric ceramic composite have been prepared. Sodium niobate (NaNbO3) has been chosen for its high Curie temperature. Moreover, it could be synthesized with two different morphologies: NaNbO3 nanowires (NN NW’s) and NaNbO3 ...

Dual Ferro‐/Piezo‐Electric Coupling in Two‐Dimensional [Bi2O2]‐Based Layered Structures for Synergistic Harvesting of Mechanical and Solar Energy

Exploration, EarlyView.
Inter‐plane 2D/2D nanosheet heterojunction based on two piezoelectric [Bi2O2]‐based layered compounds is constructed. Significantly increased piezoelectric properties of BiOBr@Bi5Ti3FeO15 by morphological regulation and interface chemical bonds. Dual‐piezoelectric field can modulate interfacial electric field and the interfacial band bending to ...

Efficient and Tunable Narrowband Second‐Harmonic Generation by a Large‐Area Etchless Lithium Niobate Metasurface

Laser &Photonics Reviews, EarlyView.
An etchless lithium niobate (LN) metasurface with a slanted periodic TiO2 grating enables efficient and narrowband second‐harmonic generation (SHG) thanks to the light confinement in the LN film granted by quasi‐bound‐state‐in‐the‐continuum (q‐BIC) modes.

A flexible arched artificial photoreceptor constructed by photodeformable liquid crystal polymers and its application in vision restoration

Smart Molecules, EarlyView.
A flexible arched artificial photoreceptor with high stability and biocompatibility was fabricated by integrating liquid crystal polymers with polyvinylidene fluoride‐trifluoroethylene. This device exhibits robust photoelectric responses under low‐intensity illumination and demonstrates efficacy in restoring visual responses in blind rats following ...

Measuring the direct piezoelectric charge coefficient for polymer matrix composites

, 2014
To realize proper measurements of the piezoelectric charge constant d33 of materials a certain mechanical load is required. Usually, this implies using a dynamic load (to evaluate the material's response) superimposed on a static preload (to achieve good

Thermodynamics‐Based THMC Model for Solute Transport in Sorptive Fractured Rock: Coupling Multi‐Phase Flow, Heat, and Deformation

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Fractured porous rocks host a complex interplay of heat, fluids, deformation, and chemical reactions, yet their combined influence on solute transport remains poorly resolved. Here we show that these processes are more tightly coupled than previously assumed.
