Summary: This study investigated the structural, dielectric, and ferroelectric properties of lead-free ceramics based on the ternary system of BaTiO3 (BT). It was observed that the dopant concentration influenced the structural evolution from tetragonal to pseudocubic phase. The dielectric response showed diffusive peaks and relaxor behavior, indicating a transition from ferroelectric to relaxor state. The ceramics exhibited slim polarization hysteresis loops and electrical inhomogeneities caused by excessive dopant addition, leading to degraded electric breakdown strength. The oxygen vacancy hopping mechanism was proposed to explain the diffuse dielectric response at high dopant concentrations.

Summary: This study introduces a simple and environmentally friendly compound method to improve the dielectric and mechanical properties of fluorosilicone rubber by using graphene nanoplatelets and barium titanate nanoparticle fillers. The results show that with the increase of graphene nanoplatelets content, both the tensile strength and dielectric constant of the composites increase without sacrificing flexibility.

Summary: HEBM powder processing promotes better phase distribution and crystallite size in HA/BT composite coatings, resulting in improved bonding strength and failure type. Additionally, HEBM treatment leads to slightly greater crystal phase stability and crystal shrinkage, as well as enhances nanomechanical properties of the coatings.

Summary: The Sc2O3 doped Ba(Zr0.1Ti0.9)O-3 ferroelectric ceramics were investigated for their microstructure, domain structure, dielectric and ferroelectric properties. It was found that Sc2O3 doping decreased the grain size, while both 90 degrees and 180 degrees ferroelectric domains coexisted in the ceramics. The phase transition temperature and dielectric permittivity maximum decreased with increasing Sc2O3 content, but the relative dielectric constant temperature stability was improved.

Summary: By investigating the temperature dependences of internal friction and Young's modulus in ferroelectric ceramics, the effects of different external conditions on the material's performance were observed. The addition of 0.2 mass. % La led to an increase in internal friction and a decrease in the internal friction maximum near the phase transition temperature.

Summary: Ultra-thin multilayer ceramic capacitors with nanograined BaTiO3-based ceramics of various grain sizes were prepared using a chemical coating method. It was found that an optimal grain size around 70 nm could achieve maximum discharge energy density under the synergy effect of breakdown strength and polarization. This study provides important guidance for the design of ultra-thin layer MLCCs by optimizing dielectric properties and energy storage performance.

Summary: We investigated the effect of A-site disorder on the properties of lead-free Ba1-x-ySrxCayTiO3 perovskites and found that decreasing A-site disorder leads to reduced tetragonal distortion, ferroelectric transition temperature, and the temperature of the maximum electrocaloric effect. By optimizing the A-site disorder, the highest adiabatic temperature change can be achieved.

Summary: High recoverable energy storage density (W-rec) and high energy storage efficiency (eta) are urgently needed for their potential application in pulse capacitor devices. However, low eta and breakdown strength (BDS) have hindered the achievement of high W-rec at high electric field. In this study, Bi(Mg0.5Ti0.5)O-3 (BMT) was introduced into Ba(Ti0.92Sn0.08)O-3 (BTS) matrix to enhance the relaxor character and reduce electrostrictive strain. The results showed significantly improved BDS and a high W-rec of 4.34 J/cm(3) with excellent temperature stability.

Summary: Ferroic switching of 90 degrees domains in BaTiO3 can be both ferroelectric and ferroelastic. Although the hysteresis characteristics of their respective ferroelectric and ferroelastic are similar, their dynamic properties are different. The switching process involves avalanches, where changes in the domain structure trigger further nanostructural changes until the avalanches stop and the sample remains in a metastable state. The energy exponent during ferroelectric switching is close to the mean field value, while stress-driven ferroelastic switching is characterized by a much larger value. BaTiO3 displays three separate dynamical processes for microstructural changes under electric and mechanical stress fields.

Summary: High-energy ball milling (HEBM) was used to investigate the effects on the sintering ability and microstructure of hafnium diboride (HfB2) ultrahigh-temperature ceramics (UHTCs). After HEBM treatment, the average particle size of HfB2 ceramics decreased and the crystal structure slightly altered, leading to improved sintering ability and densification.
