KNN-based crystals with ultrahigh piezoelectric coefficients (<italic>d</italic><sub>33</sub> = 1050 pC N<sup>−1</sup>, and <italic>d</italic><sub>33</sub>* 2290 pm V<sup>−1</sup>) were fabricated.
Large Na 0.5 K NbO 3 ( NKN ) piezoelectric single crystals were obtained by seed‐free solid‐state crystal growth method, which is a traditional sintering grain process, with LiBiO used as aid. The largest dimension of the was 11 mm × 9 mm. In addition to doping content, temperature, and time effect process systematically investigated considered from kinetics point view. With assistance Avrami analysis, parameters relevant determined. Laue diffraction transmission electron microscopy...
Ferroelectric lead-free ${\mathrm{K}}_{x}{\mathrm{Na}}_{1\ensuremath{-}x}{\mathrm{NbO}}_{3}$ (KNN) perovskite, as the representative of preferred oxides with good dielectric and piezoelectric behaviors, has attracted broad attentions in recent years. Here we systematically investigate complete process temperature dependent structural evolution manganese (Mn)-doped ${\mathrm{K}}_{0.5}{\mathrm{Na}}_{0.5}{\mathrm{NbO}}_{3}\text{\ensuremath{-}}{\mathrm{LiBiO}}_{3}$ single crystals, presenting...
Objective Excessive carbohydrate intake is a high risk factor for increased morbidity of type 2 diabetes (T2D). A novel regimen the dietary care that consists highly active α-amylase inhibitor derived from white common bean extract (WCBE) and sufficient carbohydrates was applied to attenuate T2D its complications. Furthermore, role gut microbiota in this remission also investigated. Methods We conducted 4-month randomized double-blinded placebo-controlled trial. During intense intervention...
Using the solid‐state ceramic route, Ca 4 La 2 Ti 5− x ( Mg 1/3 Nb 2/3 ) O 17 (0 ≤ 4) ceramics were prepared, and phase purity, microstructure, microwave dielectric properties investigated. The XRD results suggest formation of solid solutions for all studied compositions unit cell volume increases linearly with . SEM also show no evidence secondary doping at site promotes grain growth. ε r sintered decreases from 71.86 to 35.23, Q × f value 15 070 21 277 GHz τ varies 125.2 −16.7 ppm/°C...
The Na0.5K0.5NbO3 single crystal was successfully grown by a seed-free solid-state growth method using super-low content of LiBiO3 as sintering aid. Microstructure, piezoelectric, ferroelectric and dielectric properties were investigated. results show that well-paralleled lamellar ordering domains structure are present no crack can be seen inside the crystal. best piezoelectric (at 1 kHz) d33 = 265 pC/N, Pr 27.4 μC/cm2, ε 738, tanδ 0.04 appear at x 0.40at% for (1-x)Na0.5K0.5NbO3-xLiBiO3 A...
