Summary: In this study, Cold Sintering was applied to densify a Potassium-Sodium Niobate solid solution composition, resulting in ceramics with comparable dielectric and electrical properties as conventionally sintered KNN. TEM analysis revealed high density of line defects in grains and crystalline grain boundaries with faceted kinks, which limit the piezoelectric properties and hysteresis of the ceramics.

Summary: The rapid development of electronic information technology has given optoelectronic ceramics a new mission, which is high performance and versatility. Er3+-doped 0.94(K0.5Na0.5)NbO3-0.06(Sr0.5Ba0.5)(Bi0.5Nb0.5)O-3 ceramics were prepared by conventional solid-phase methods. At x = 0.2, the ceramic obtains a high transmittance of 80.14% in the near-infrared region (1100 nm) due to the high structural symmetry, dense microstructure, and large optical band gap energy (E-g). The up-conversion photoluminescence (UCPL) spectrum shows the high emission intensity obtained at x = 0.4, revealing the outstanding luminescence properties of the ceramic. The dense microstructure and small grains give the ceramics high dielectric breakdown strength (DBS). Thus, at x = 0.2, the ceramic obtains excellent comprehensive electrical properties with W-rec and eta of 1.25 J/cm(3) and 58.56%, respectively. This ceramic is highly attractive for high-performance and multi-functional optoelectronic ceramic devices.

Summary: Single-phase ceramic samples with new compositions (1 - x - y)(Na0.5Bi0.5)TiO3-xBaTiO(3)(-) y.(K0.5Na0.5)NbO3 (x = 0.05,. = 0-0.15) modified with ZnO and GeO2 additions were obtained by solid-phase synthesis. Their crystal structure, microstructure, and dielectric and local piezoelectric properties were studied. A phase with a perovskite structure with a pseudocubic unit cell was found to form in all of the synthesized samples; it was shown that the unit cell volume increased as a result of the partial replacement of base cations by complex additive cations. The ferroelectric phase transitions were confirmed by dielectric spectroscopy. Residual piezoelectric hysteresis loops were obtained for the synthesized samples in the polarization switching spectroscopy mode, which confirmed the switching of ferroelectric polarization.

Summary: A solid-state reaction sintering process was developed to fabricate (K0.5Na0.5)NbO3-xBaNi(0.5)Nb(0.5)O(3-delta) (KNN-xBNN) ceramics with narrow bandgap and room-temperature ferromagnetism. The influence of BaNi0.5Nb0.5O3-delta (BNN) concentration on the properties of KNN-xBNN ceramics was systematically investigated. The narrow bandgap and room-temperature ferromagnetism in the lead-free perovskite KNN-xBNN ceramics were found to be induced by Ni2+-oxygen vacancy combinations and BNN doping.

Summary: In this paper, the structure, ferroelectric, and piezoelectric properties of Bi2O3-doped lead-free ceramics were studied. It was found that doping Bi2O3 increases the proportion of the trigonal phase in the ceramics, enabling the construction of ceramics with an orthogonal-trigonal phase boundary at room temperature. Additionally, doping with Bi2O3 reduces grain size and improves grain size uniformity. The ceramic with 0.1% Bi2O3 doping showed the best piezoelectric properties.

Summary: Air-gapped VTIs demonstrate large inductance tunability through electric field modulation of permeability, but there is a tradeoff between tunability and saturation current. The introduction of air gap significantly reduces tunability while increasing saturation current, and the air gap affects the magnetization, permeability, and tunability of VTIs.

Summary: A novel method for determining the optimal material coefficients of piezoelectric ceramics was presented, which minimizes the average relative error in values obtained from experimental measurements and modeling. This method considers elastic, piezoelectric, dielectric coefficients, and Poisson's ratio as complex numbers, and finds the global minimum of the average relative error by searching among local minima. The uncertainties in the optimal material coefficients were evaluated by calculating minimum average relative error with prescribed real or imaginary parts.
