Summary: This study explores the importance of temperature-dependent spontaneous strain in halide perovskites. By investigating the optical properties, X-ray diffraction, and dielectric properties of CsPbBr3 single crystals, it is found that this material undergoes two phase transitions and exhibits ferroelastic behavior under external electric field or stress. Furthermore, it is discovered that anomalies in certain properties previously attributed to additional phase transitions are actually artifacts caused by changes in the ferroelastic domain structure and internal strain.

Summary: The study improved the stability of rare-earth based CsEuCl3 perovskite nanocrystals by employing a silica-coating and observed the formation of hollow regions inside the nanocrystals resulting in a blue-shifted PL emission. Density functional theory calculations revealed that the hollow regions are due to internal defect evolution in the lattice, causing an increase in bandgap and blue-shift in emission.

Summary: It is challenging to achieve high d33 and d33* simultaneously in a piezoelectric ceramic system due to the conflicting structure-properties responding mechanism. In this study, a synergistic approach of constructing a morphotropic phase boundary and introducing internal bias fields has been proposed to mitigate this conflict. The results show that by using this strategy, both high d33 and d33* have been realized in Srx(Bi1-xNa0.97-xLi0.03)0.5TiO3 when x=0.24. This work opens up a new path for developing lead-free ceramics with excellent piezoelectric performance.

Summary: This study aimed to solve the quantitative problem of the magnetic flux leakage (MFL) internal detection signals of long-distance oil and gas pipelines. Based on the magnetic charge theory, a numerical-analytical model for MFL internal detection of pipeline complex defects was constructed by introducing stress factor in this work. The effectiveness of the model was verified through experiments, and the results showed significant improvement in the accuracy of magnetic signal analysis by determining the optimal division size on the end face defects. The study also analyzed the distribution pattern and characteristics of magnetic signals under different geometric sizes and stresses of defective end-face.

Summary: Composite modulation in the superparaelectric state of the BTBZ-CT system is proposed as an effective strategy to achieve both NTCC and excellent energy storage performance in dielectric ceramics. The addition of BZ and CT to BT ferroelectrics can move the SPE state to the normal use temperature zone, resulting in enhanced NTCC characteristics and energy storage performance. Furthermore, intentional precipitation of CT at grain boundaries can refine the grain size, increase the bandgap, and strengthen the local electric field distribution, thereby enhancing the breakdown electric field.

Summary: This study analyzes the influence of calcia refractory purity on the properties of calcia crucibles. Higher purity calcia results in well-developed grains and improved hydration resistance, leading to better high-temperature strength and thermal shock resistance. In contrast, lower purity calcia crucibles exhibit inferior properties. Therefore, high-purity calcia is considered a potential refractory for manufacturing oxide crucibles.

Summary: To raise the operating temperature of Si-based ceramic matrix composites (CMCs), researchers have applied thermal/environmental barrier coating (T/EBCs) materials, typically rare earth silicates. However, the high thermal conductivity and the mismatch of thermal expansion have been major challenges in developing new materials that can offer thermal insulation and environmental protection to CMCs. In this study, entropy engineering was used to create a multicomponent equi-atomic single-phase pyro silicate with extremely low thermal conductivity and enhanced water vapor corrosion resistance. The research findings show the potential of high entropy disilicates in achieving ultra-low thermal conductivity and low weight loss in corrosive environments.

Summary: This study provides an atomic-scale description of the high-velocity impact of alpha-Al2O3 particles onto an alpha-Al2O3 substrate during Aerosol Deposition (AD). The results suggest that the crystal orientation plays a crucial role in both plasticity and damage of the nanoparticles. Impact velocity has a direct correlation with plasticity and fragmentation, but adhesion efficiency has only a marginal increase. The crucial element lies in the substrate's surface alterations caused by the fragments left on the substrate after impact.

Summary: This study characterized the long-term and repeated ablation properties of modified Cf/HfC-SiC composites with YB4-Al2O3-Si3N4 under an air plasma torch. The structural stability and viscosity of the oxide layer were found to affect the ablation resistance of the composites. By forming nano c-HfO2 grains and high-viscosity Al-Si-Y-O glassy phase, the structural stability of the oxide layer was improved, resulting in enhanced ablation resistance. However, the oxidation of Si3N4 led to the formation of NO, NO2, and excessive SiO2 glassy phase, which resulted in a porous structure and reduced the viscosity of the oxide layer. Therefore, the addition of Si3N4 decreased the ablation resistance of the composites.

Summary: In this study, solid solutions of xBi(Ni1/2Hf1/2)O-3-(1 - x)PbTiO3 (xBNH-PT) were synthesized to investigate their phase boundary behaviors and physical properties. The presence of a tetragonal-pseudocubic phase boundary and a spontaneous ferroelectric-relaxor transition at specific compositions were confirmed. The introduction of a tetragonal-pseudocubic phase boundary improved the piezoelectric properties and suppressed the spontaneous ferroelectric-relaxor transition.
