Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers
Advanced Functional Materials, EarlyView.We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Optical “fingerprints” of dielectric resonators
Journal of the Optical Society of America B, 2023 The complete picture of the optical properties of resonant structures, along with the frequency, quality factor, and line shape in scattering spectra, is determined by the electromagnetic field distribution patterns, which are a kind of “fingerprint” of each resonant eigenmode. In this paper, we simultaneously analyze the changes in the spectra and the

Micromechanical resonator with dielectric nonlinearity [PDF]
Microsystems & Nanoengineering, 2018 AbstractNonlinear response of dielectric polarization to electric field in certain media is the foundation of nonlinear optics. Optically, such nonlinearities are observed at high light intensities, achievable by laser, where atomic-scale field strengths exceeding 106–108 V/m can be realized.

Advanced Functional Materials, EarlyView.A Li2O‐rich solid electrolyte interphase (SEI) is engineered on graphite through a propylene carbonate‐based electrolyte to spatially regulate Li plating. The homogeneous interphase lowers Li nucleation barriers, promotes conformal Li deposition around graphite particles, and suppresses dendritic accumulation, enabling durable hybrid Li‐ion/Li‐metal ...
