Summary: This study investigated the preparation of hollow tin dioxide (SnO2) nanofibers using electrostatic spinning technique and calcination process. The morphology was observed using X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM), and the chemical state of the elements was characterized using X-ray photoelectron spectroscopy (XPS). Gas-sensitive tests showed that the response of SnO2 hollow nanofibers to ethanol at a concentration of 100 ppm reached 27.13 at the optimum temperature of 350°C. The response and recovery times were 42 and 35 seconds, respectively, and the theoretical detection limit of the sensor was as low as 2.944 ppm. Density functional theory (DFT) calculations demonstrated that the adsorption mechanism of ethanol gas on the surface of tin dioxide was due to impedance change caused by electron transfer, making it more selective towards ethanol gas.

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: 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.
