Summary: This study investigates the formation mechanism of depolarization temperature (T-d) in Bi0.5Na0.5TiO3 (BNT) ceramics and proposes a novel design strategy to simultaneously enhance the piezoelectricity and defer T-d by introducing ferroelectric components with different local symmetries. This work provides insights into the design of high-performance materials based on BNT, benefiting the understanding and improvement of BNT-based relaxor ferroelectrics.

Summary: In this study, BNT-6BT-xSm ferroelectric ceramics with different doping contents of samarium (Sm) were prepared using the solid-state reaction method. The introduction of Sm into the ceramic system led to a transition from order to disorder. The ceramics exhibited reduced grain size, decreased remnant polarization, and coercive field with increasing Sm content. However, the maximum electric field-induced strain and piezoelectric coefficient reached their highest values at a certain composition. Therefore, BNT-6BT-0.03Sm lead-free ferroelectric ceramic shows promise as a substitute for lead-based ferroelectric ceramics for piezoelectric actuators.

Summary: The BNBT-ZnO ceramics, with Zn-2 ions entering the BNBT lattice, were prepared by solid-state reaction technique at sintering temperatures ranging from 1000°C to 1050°C. The ceramics exhibited two phases, BNBT phase and ZnO phase, and had a relative density higher than 97% when sintered between 1010°C and 1040°C. The ceramic sintered at 1040°C showed the best electrical properties with a dense microstructure, average grain size of 1.0 μm, and high values of d(33) and T-d at 110 pC/N and 97°C, respectively.

Summary: In this study, high-dielectric (1 - x)(Bi0.5Na0.5)TiO3-x(Ba0.85Ca0.15)(Zr0.1Ti0.9)O-3 (BNT-BCZT) ceramics were fabricated by combining solid-state sintering technique and two-part synthesis. XRD measurements confirmed the formation of a stable solid solution between BNT and BCZT. The BNT-BCZT ceramics exhibited larger piezoelectric constant, lower remnant polarization, and lower coercive field compared to pure BNT ceramics.

Summary: The harvesting of mechanical energy from our living environment using piezoelectric energy harvesters for wearable electronic devices and sensors has gained interest. Porous piezoelectric ceramics show potential for energy harvesting due to their reduced relative permittivity. However, low output power density and lack of optimized design limit their application. This study proposes a lead-free multi-layer porous piezoelectric composite energy harvester with aligned pore structure and intercalation electrodes, showing higher power density than other materials.

Summary: This study investigates the temperature stability of the quasi-static magnetoelectric response of lead-free NKBT-NFO laminated composites. The results demonstrate that the magnetoelectric response of NKBT/NFO is highly sensitive to temperature, decreasing with heating according to the temperature-dependent properties of NKBT and NFO.
