Summary: The glass-forming ability of strontium tellurite and lead tellurite melts is affected by the temperature, with high temperature melts freezing faster into crystalline phases, while low temperature melts are more likely to form glassy phases. Slow structural transformations in the melts lead to memory effects, influencing their glass-forming ability.

Summary: The population bottleneck of Er3+: 4I11/2 -> 4I13/2 was overcome in Er3+/Pr3+ co-doped TBLL glasses. Pr3+ ions depleted electrons from Er3+: 4I13/2 level faster than from Er3+: 4I11/2 under 980 nm excitation. The energy transfer efficiency and mechanism of Er3+ and Pr3+ ions were investigated. Numerical simulations indicated the potential applications of Er3+/Pr3+ co-doped TBLL glass in mid-infrared fiber lasers.

Summary: Transparent fluorotellurite glasses were successfully prepared in the ternary system TeO2-Nb2O5-PbF2, allowing high incorporation of PbF2 without loss of glass forming ability. Compositions with higher PbF2 contents exhibit preferential precipitation of lead oxyfluoride at lower temperatures, which is controlled by a volume nucleation mechanism. Doping with Eu3+ promotes efficient nucleation and leads to transparent glass-ceramics with higher quantum efficiencies, making these new glass compositions promising hosts for luminescence applications in the middle infrared region.

Summary: Transparent tellurite glass-ceramics have significant potential in the field of photonics due to their unique nanostructured crystalline phases. By doping with rare earths and controlling the heat treatment process, optical transparency can be achieved in glass-ceramics, allowing for in-depth analysis of crystalline phases, micro/nanostructure, and unique properties. However, there are still limitations in current research that need to be addressed for further improvement.

Summary: This paper reports the structural, thermal, and optical properties of Er3+ doped germanate glasses with various compositions. The glasses exhibit low phonon energies and high glass transition temperatures. Raman spectra show different polymerization degrees of the glasses.

Summary: The thermometric sensitivity of different Eu3+ doped glasses in different glass systems was theoretically calculated using the Judd-Ofelt parameters and compared to experimental data. The study aimed to test the limitations of thermal sensitivity estimation using Judd-Ofelt parameters in various glass systems. Discrepancies between theoretical and experimental values were observed in germanate and tellurite glasses due to their low phonon energies, which caused the failure of the Boltzmann model. Phosphate glasses, with their high absolute thermometric sensitivity, are promising materials for luminescence thermometers.

Summary: Phosphate glasses are promising alternative materials to replace traditional silicate bioactive glasses due to their controlled ion release behavior. A newly developed bioresorbable phosphate glass containing Sr and Mg demonstrated slower dissolution rate and maintained their ability for congruent dissolution and hot forming. The substitution of SrO for MgO effectively enhanced the sintering ability of the material, enabling the processing of scaffolds with mechanical properties above that of cancellous bone.

Summary: We have developed core-clad bioactive borosilicate fibers with round and rectangular cross-section profile by stacking and drawing glass slabs. Tens-of-meters-long fibers were successfully drawn, but rectangular ones suffered from elevated losses due to the enhanced corrosion caused by residual tensile stress. This study provides the first report on the effect of residual tensile stresses on the corrosion of rectangular fibers and highlights the importance of geometry in the biodegradation behavior of fiberglass.

Summary: In this study, silicate glass containing crystals were prepared by melting a mixture of YbPO4 xenotime structured crystals and SiO2 nanoparticles. The mixture was used to prepare large volume core preforms for laser active optical fiber. The integrity of the crystals in the preform and fiber were assessed through temperature dependent sintering and fiber drawing experiments. The survival of YbPO4 crystalline particles in silica was investigated using various techniques, showing that the particles withstand the high-temperature steps during the fiber fabrication process. However, partial decomposition of the crystals was observed during the fiber fabrication.

Summary: The method of directly introducing crystals of known chemistry, size, and optical properties into a glass matrix is useful in overcoming limitations in controlling crystal growth in glass-ceramics. By measuring changes in micro-luminescence spectra, it is possible to track the decomposition of crystals inside the composite material. It has been shown, for the first time, that adding Eu3+-doped LaPO4 crystals to phosphate fluoride glasses enhances the thermometric sensitivity of Eu3+ ions, making it promising for temperature sensing applications.

Summary: In this study, a sustainable solution for radiochromic detection is proposed using hackmanite, a natural intelligent material. Experimental evidence shows that hackmanite exhibits radiochromic properties when exposed to different particles and radiation, and the mechanism of gamma-induced radiochromism in hackmanite is elucidated using both experimental and computational data. Hackmanite can be used for gamma dose mapping in high dose applications and has the ability to remember earlier gamma exposure, making it a promising replacement for the currently available radiochromic films. It is also non-toxic and reusable.

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.
