Summary: In this study, a series of piezoelectric ceramics with the formula Pb0.93Sr0.06Ba0.01(Mg1/3Nb2/3)(0.035)(Ni1/3Nb2/3)(0.2)(Sb1/2Nb1/2)(0.015)(ZrxTi1-x)(0.75)O-3 + 0.5 wt. % Li2CO3, where x = 0.51, 0.50, 0.49, 0.48, 0.47, and 0.46, were successfully prepared using the one-step solid-state method. The results showed that the crystalline structure gradually transformed from rhombohedral to tetragonal phase with decreasing Zr content. Moreover, the piezoelectric ceramics with x = 0.49 exhibited outstanding electrical properties near the morphotropic phase boundary, indicating great potential for transducer applications.

Summary: Piezoelectric materials are essential for energy generation and harvesting devices, but Pb-based materials are still irreplaceable despite their toxicity due to their superior piezoelectric properties. This study proposes a compromise strategy to design low Pb content piezoelectric materials by creating a morphotropic phase boundary (MPB) in a pseudo-binary system. The optimized composition near the MPB exhibits high piezoelectricity comparable to conventional Pb-based materials but with significantly reduced Pb content.

Summary: This study systematically investigates the effects of phase transitions on the electrostrictive and piezoelectric behaviors in PMN-30PT single crystals, revealing that electric field-dominated transitions exhibit maximum electrostrain at each transition point, while d(33) peaks at specific transition points. Temperature-dominated transitions also contribute towards minor peaks in electrostrain and/or d(33).

Summary: This study investigated the effects of individual and simultaneous doping with niobium (Nb5+) and neodymium (Nd3+) cations on electrospun PZT nanostructures. Various analyses were performed to examine the influence of the Dopant-Acceptor (D-A) combination on the morphology, crystallography, and boundary of the PZT nanostructures. The results showed that nanowhiskers of PZT were formed after calcination at 800°C for 2 hours. The morphology was minimally affected by individual Nb and Nd doping, but co-doping led to a switch to nanoneedles. The presence of Nb resulted in a perovskite PZT phase, while Nd resulted in a Ti-rich tetragonal phase. The Zr 3d spectrum of XPS analysis indicated that the closest composition to the morphotropic boundary (MPB) was achieved with Nb-Nd co-doping. The dielectric properties of the doped PZT samples were also investigated, with the highest dielectric constant observed in the Nb-Nd co-doped sample. Overall, this study suggests that the electrospinning method can be utilized to achieve nanostructured PZT with high dielectric constants.

Summary: Ferroelectric and piezoelectric polymers have attracted attention for their mechanical robustness, flexibility, cost-effectiveness, and easy processibility. However, the electrical performance of piezoelectric polymers is difficult to reach that of piezoelectric ceramics. Recent research has confirmed the concept of morphotropic phase boundary (MPB) in P(VDF-TrFE) piezoelectric copolymers, showing exceptional behaviors similar to MPB and relaxor ferroelectrics. Electrospun P(VDF-TrFE) nanofibers have been developed to exceed the performance limitations of existing materials. This study is a first step towards practical applications of a new generation of piezoelectric polymers.

Summary: In this study, in-situ synchrotron x-ray diffraction and transmission electron microscopy were conducted to investigate the structural mechanism of BF-PT-0.19Ba(Zr,Ti)O3 high-temperature piezoceramic. It was found that an irreversible transition from tetragonal phase (T phase) to rhombohedral phase (R phase) occurred after poling, leading to significantly enhanced irreversible domain switching of both R and T phases. This study provides a new mechanism for designing high-performance high-temperature piezoelectric ceramics.

Summary: The lead-free BNKLT-Sm ceramics were synthesized using solid-state combustion technique with varying calcination and sintering temperatures. Increasing the calcination temperature resulted in increased perovskite phase percentage and particle size. The ceramics exhibited coexisting rhombohedral and tetragonal phases with the dominance of R phase at higher sintering temperatures, showing anisotropic growth in microstructure. Relaxor characteristics were observed in dielectric and ferroelectric behavior, with the densest ceramics sintered at 1075 degrees C for 2 hours showing the highest dielectric constant and remnant polarization.

Summary: In this study, dielectric spectroscopy and the complex electric modulus formalism were used to characterize the electrical properties of Ti0.8O2 nanosheets-Ag nanoparticles-cellulose filter paper composites, which are intended for use as a triboelectric nanogenerator. The addition of these fillers increased the dielectric permittivity and AC conductivity, while maintaining a low loss tangent. The analysis revealed a three-dimensional hopping mechanism in the composited films, contrasting with the conduction in ceramics. The Ti0.8O2 nanosheets acted as a charge generation/reservoir, while the Ag nanoparticles generated long-range conduction paths.

Summary: The effect of BBF content on the phase formation, microstructure, and electric and magnetic properties of lead-free ceramics was studied. As the BBF content increased, the average grain size, density, and relative density decreased, while the unit cell volume increased. The dielectric constant decreased and the dielectric loss increased. Ferroelectricity decreased and leakage current increased with increased BBF content. The ceramic changed from diamagnetic to paramagnetic properties, with an increase in remnant magnetization.

Summary: The triboelectric nanogenerator (TENG) is a promising technology that converts mechanical energy into electricity efficiently. However, the pulsed alternating current output of TENG needs to be rectified to direct current (DC) for practical applications, leading to limitations in conversion efficiency, size, and portability. The development of a DC TENG, known as the tribovoltaic nanogenerator (TVNG), has recently emerged, offering continuous DC output with enhanced carriers through the tribovoltaic effect.

Summary: In this study, the impedance spectroscopy of carbon nitride nanosheets (CNNS) and the composite with anatase (TiO2/CNNS) were investigated, along with their interaction with atmospheric water. The results showed that CNNS is highly insulating, while the incorporation of TiO2 nanoparticles significantly reduced the resistivity of the composite and the decrease in resistivity was proportional to the exposure time to atmospheric water. This study provides important insights into the water-induced transport of TiO2/CNNS composite without the need for complicated curve fitting procedures or dedicated humidity control.
