Summary: In this study, low dielectric constant composites with higher thermal conductivity were prepared by combining ZIF-8 insulation and graphite nanosheets (GNS) thermal conductivity in an epoxy resin matrix. The ZIF-8@GNS/EP (ZGNS/EP) composites showed a decrease in dielectric constant by 26.4% and an increase in thermal conductivity by 300.7% compared to neat EP. The composites exhibited a dielectric loss always lower than 0.033 (10^2-10^7 Hz) and a significant increase in tensile strength. Overall, this work introduces a new concept for preparing low dielectric constant materials with low loss and excellent thermal conductivity.

Summary: In this study, SiC fiber and Yb2SiO5 composites were processed using the Spark Plasma Sintering (SPS) method. Different types of interfaces were achieved by adjusting the sintering temperature. It was found that the thermal expansion mismatch between Yb2SiO5 and SiC led to high interface stress, and the high temperature and electric field also had an effect on the interface. The study suggests that introducing the Yb2Si2O7-Yb2SiO5 phase can adjust the interfacial parameters and optimize the mechanical properties of the material.

Summary: This study investigates the temperature-dependent structural and mechanical/thermal property evolution of multicomponent rare-earth zirconates. Molecular dynamics simulations are used to reproduce the experimental results. It is found that with increasing temperature, the polyhedrons deform more, resulting in reduced mechanical properties and thermal conductivities. The multicomponent design at the Zr-site is suggested to be important in the design of thermal barrier coatings using pyrochlores.

Summary: In this study, CBS glass/Al2O3 composites were developed for LTCC applications based on a CaO-B2O3-SiO2 (CBS) glass system with a high boron content. The study revealed that the softening of glass and interfacial reaction between the glass and Al2O3 were the two most important factors affecting LTCC's densification process. Real-time shrinkage rate of LTCC during sintering was successfully simulated, and it was proven that the formation of the CaAl2(BO3)O phase played a significant role in reducing glass viscosity and promoting dense structure formation. The resulting LTCC composite exhibited excellent performance for high-frequency applications.

Summary: In this study, the disordering caused by swift heavy ion irradiation in two different compositions of pyrochlore structures was investigated. X-ray diffraction, Raman spectroscopy, and high-resolution transmission electron microscopy were used to analyze the samples before and after irradiation. It was found that both compositions underwent amorphization due to irradiation, with a slower rate observed in Nd1.8Zr2.2O7.1. The irradiation-induced modified track region in Nd1.8Zr2.2O7.1 consisted of defect-rich pyrochlore structure, anion-deficient fluorite structure, and amorphous domains.

Summary: Silicide ceramics, including tantalum disilicide (TaSi2), are known for their exceptional physical properties but are limited in practical applications due to their inherent brittleness at room temperature. In this study, we successfully improved the mechanical properties of TaSi2 ceramics and increased their electrical conductivity by modifying the preparation methods and sintering conditions. These findings provide valuable insights for future applications of TaSi2 and the design of advanced ceramic materials.

Summary: Microstructure design plays a crucial role in regulating the microwave dielectric properties of materials, however, the understanding of frequency temperature stability and related micromechanism remains limited. In this study, a combination of first-principles calculations and experimental observation was used to investigate the correlation among sintering behavior, crystal structure, bonding nature, and microwave dielectric properties of LnPO(4) (Ln = Eu, Pr) ceramics. The research findings systematically clarify the optimized effect and micromechanism of lanthanides on the dielectric properties of monazite ceramics, providing insights into the design and enhancement of microwave dielectric materials.

Summary: The study investigates the frictional and wear behaviors of carbon fiber-reinforced SiC ceramic matrix composites with different fiber orientations mating with ceramic balls. The results show that fiber orientation significantly affects the friction and wear properties of the composites. Pads with randomly arranged fibers demonstrate better friction stability and lower wear volume, potentially suitable for bearing material applications. The research also explores the factors influencing the formation of continuous tribo-film and identifies abrasive wear and oxidation wear as the dominant wear mechanisms for the friction pairs.

Summary: This study investigates the effect of K/Na ratio on the phase structure, ferroelectric domains, and piezoelectric properties of potassium sodium niobate (KNN)-based ceramics. It reveals that high Na+ content leads to large ferroelectric domains, while high K+ content results in local polarity heterogeneity and distinct dielectric relaxational behavior. The balanced local polarity and stress heterogeneities contribute to improved piezoelectricity.
