Summary: Raman spectra of synthesised As2S3:Sn samples reveal their amorphous nature at a moderate excitation power density. However, when measured at a higher excitation power density, the sample surface experiences local heating and the emergence of SnS2 crystallites. This effect is responsible for the observed SnS2-related feature in the Raman spectra.

Summary: The confinement of CsPbX3 perovskite nanocrystals in a stabilized inorganic glass matrix improves their stability and allows tuning of emission peaks, showing potential for applications in the optoelectronic field. The development of in situ nanocrystallization strategy successfully precipitates CsPbBr3-xIx NCs with arbitrary I/Br ratio in a carefully designed chalcogenide glass matrix, showcasing homogenous distribution within the glass matrix and potential applications in the photoelectronic fields. The presence of structural defects in the NCs leads to a short PL decay life, but sheds light on the future potential for these materials.

Summary: CsPbX3 (X = Cl, Br, I) perovskites have unique properties that make them suitable for various applications. This study focuses on CsPbCl3 perovskite doped with 9% Yb3+ ions, prepared using a solid-state reaction method. The obtained sample showed phase purity, micrometer size, and non-hygroscopic properties even after one year of synthesis. Spectroscopic analysis revealed that the luminescence mechanism in CsPbCl3:9%Yb3+ perovskite is dependent on the average grain size.

Summary: Compared with CsPbBr3 perovskite quantum dots, CsPbCl3 quantum dots are difficult to precipitate in a glass matrix. In this study, CsPbCl3-xBrx (X < 3) quantum dots in phosphate glasses are prepared using a mechanical crystallization method. Experimental results show that CsPbBr3 quantum dots are easily obtained in the glass matrix under stress, but with the increase of Cl- content, obtaining Cl-containing quantum dots becomes challenging, and the mechanism is further studied. Raman spectra reveal that the difficulty in precipitating Cl-containing quantum dots is attributed to the closer glass network structure. Scanning electron microscope results further demonstrate that the uniformity of the glass matrix improves and macroscopic defects decrease with the increase of Cl composition, resulting in the reduction of shear bands under stress, which inhibits the nucleation and growth of quantum dots.

Summary: The atomic structure of glass along the P4Se3-As4Se3 join with different compositions was studied using various spectroscopic techniques. The results showed the coexistence of cage-like molecular moieties and corner-shared network moieties in these glasses. The increase in substitution of As with P correlated with an increase in the ratio of molecules to network, which also affected the glass transition temperature.

Summary: This study investigates the luminescent mechanism of Cs4PbBr6 by analyzing the real-time formation process of nanocrystals, identifying two stages in the process and extracting the activation energy for the transformation. The observation of transformation from white to black spots suggests that the black spots are responsible for photoluminescence emission, despite their amorphous nature.

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 reveals the significant influence of resting time on the rheological properties of cement suspensions, which is closely related to non-absorbed polycarboxylate superplasticizers (PCEs) size variation. Adsorbed PCE during resting tends to bridge particles instead of dispersing them, leading to an increased yield stress.

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.
