Summary: This study found that the phase transition sequence of K0.5Na0.5NbO3 ceramics includes a previously unreported structural and polar phase at low temperatures, regardless of the processing method used. However, there were significant changes in the stability temperature interval of different phases. The dielectric properties and the emergence of dielectric relaxation phenomenon were also found to be dependent on the processing method, likely due to the effect of different grain sizes.

Summary: The emerging smart PVDF-based composites can address the intrinsic property deficiencies in their components. The properties of these composites are determined by their constituents and fabrication method. In this study, potassium sodium niobate (KNN) and MWCNTs were used as primary reinforcement and to improve electrical properties, respectively. Solution casting was employed to prepare PVDF-KNN-CNT composite films. SEM, XRD, FTIR, and TGA methods were used to characterize the composites, and dielectric, piezoelectric, and ferroelectric properties were investigated. The results showed that the composites' dielectric, piezoelectric, and ferroelectric properties strongly depend on KNN content.

Summary: By using dielectric relaxation techniques at low and high electric fields, it is possible to obtain the conductivity and structural relaxation times for conductive materials, such as ionic liquids, under the same sample conditions. This approach is especially useful when the low field dielectric loss spectra do not show any signatures of structural relaxation. The experiment on viscous 1-butyl-3-methyl imidazolium tetrafluoroborate demonstrates that the structural relaxation is about nine times slower than the conductivity relaxation.

Summary: In this study, (0.95-x)K0.48Na0.52NbO3-0.05SrTiO(3)-xCaZrO(3) piezoelectric ceramics were prepared and their microstructures, phase structures, and ferroelectric, dielectric, and strain properties were investigated. The crystal structure of the ceramics changed from orthogonal-tetragonal coexistence to tetragonal-orthogonal coexistence by improving the transition temperature with increasing CaZrO3 doping. These materials exhibited a high electric field-induced strain and excellent ferroelectric and dielectric properties, making them promising candidates for lead-free ceramics in the future.

Summary: This paper reports a novel lead-free tungsten bronze type ceramic, Sr5BiTi3Nb7O30, which exhibits second-order non-linear optical behavior and ferroelectric properties. The disorder on the A and B sites in Sr5BiTi3Nb7O30 leads to strong frequency dispersion and a low phase-transition temperature. The temperature dependence of the dielectric responses is described using a statistical model, and the calculated sizes of polar nanoregions imply a more diffuse ferroelectric transition.

Summary: Tungsten bronze ceramics were prepared using the solid-state reaction method to study the influence of La3+ concentration on the microstructure, dielectric, and ferroelectric properties of Sr4 - xNa2 - xLaxTa0.6Nb9.4O30. The introduction of La3+ promoted dipole-glass-like behavior and enhanced dielectric relaxation. Calculations and analysis of polar nanoregions (PNRs) revealed that the stability of the dielectric constant is inversely related to the size of PNRs. It is crucial to obtain small size and a high number of active PNRs, as well as a weak coupling between PNRs and other polar clusters, for energy storage performance. A high energy storage density of 2.06 J/cm(3) was achieved in Sr3.8Na1.8La0.2Ta0.6Nb9.4O30.

Summary: Through local structure design, we demonstrate that a lead-free relaxor with a simple chemical composition can achieve simultaneously high energy density (Wrec) and high efficiency (eta), as well as excellent thermal and frequency stabilities. By introducing Bi with 6s2 lone pair stereochemical activity into the classical BaTiO3 ferroelectric, a relaxor state with strong local polar fluctuations can be formed, resulting in a slush-like structure with extremely small size polar clusters and minimized hysteresis at a high breakdown strength.

Summary: Efficient and environmentally friendly ferroelectric BSLNT ceramics were prepared and used as tribocatalysts for organic degradation. The catalytic capability was improved by enhancing the ferroelectric properties, leading to 92% RhB degradation after 2 hours. Further enhancement of the catalytic efficiency was achieved through electrical poling, reaching 96.8% degradation in 2 hours. Under the synergistic effect of illumination and friction, the degradation efficiency of RhB reached 95.2% after 30 minutes. This study demonstrates the application of highly efficient ferroelectric tribocatalysts for dye wastewater degradation, expanding the use of ferroelectric materials in catalysis.

Summary: This study investigates the impact of a monolayer of graphene on the secondary electron emission (SEE) of an Ni (111) surface through theoretical calculations and experimental analysis. The results show that the redistribution of electron density at the graphene/Ni (111) interface leads to variations in the work function and probability of SEE. Experimental measurements confirm a significant decrease in the secondary electron yield (SEY) on the Ni (111) surface covered with graphene, consistent with the correlation between work function and SEY in metals.
