Summary: A new type of glass-ceramic BCAS was developed to join Al2O3 ceramics, and TiO2 was added to promote the crystallization behavior of the glass-ceramics. Rutile TiO2 whiskers were observed to grow on the surface of Al2O3 ceramics in the joints, providing mechanical support. The density of TiO2 whiskers in the joint was found to be the largest when the amount of TiO2 added was 10% (wt%), resulting in the best strengthening effect with a shear strength of 94.33 MPa.

Summary: This study investigated the structure, thermal stability, spinnability, and fiber tensile strength of CaO-MgO-Al2O3-SiO2 glasses with SiO2 replaced by Al2O3. Results showed that increasing the molar ratio of Al2O3 to SiO2 led to an increase in the polymerization degree of the glass network structure, resulting in higher Tg and thermal stability. The characteristic temperatures and fragility of glassy melts also increased with the increase in Al2O3 to SiO2 ratio. Moreover, the fiber spinnability parameters showed a different trend as the Al2O3 to SiO2 ratio increased, but both indicated the feasibility of continuous fiberglass production.

Summary: The SiO2-deposited Al2O3-SiO2 aerogel (Si-ASA) with high thermal stability and mechanical properties was synthesized by silica deposition method. Compared with ASA without silica deposition, Si-ASA maintains higher specific surface areas after being calcined at high temperatures, inhibits the formation of mullite phase, and restrains the growth of gamma-Al2O3 by forming more Si-OA-l bonds.

Summary: The impact of adding Eu2O3 and Nd2O3 on the crystallization behavior of NAS glasses was discussed, revealing that the addition of rare-earth oxides resulted in decreased crystallization activation energy and increased Avrami parameter n, indicating a tendency towards bulk crystallization and two dimensional crystal growth. As the heating temperature increased from 650 to 780 degrees Celsius, ZrO2, low-carnegieite, and nepheline crystals successively precipitated in NAS glasses, with Nd2O3 showing more effectiveness in promoting crystallization and forming ultra-fine microstructure compared to Eu2O3.

Summary: The study investigated the roles of citrate and phosphorylated proteins in bone mineralization, finding that they exhibit different characteristics and binding modes with the hydroxyapatite surface at different pH values. Phosphorylated proteins showed a stronger binding affinity to the (100) surface compared to the (001) surface. Citrate displayed similar adsorption affinities on different surfaces, while the surface adsorption of phosphorylated proteins was mainly influenced by the phosphate group.

Summary: In this study, the thermal, mechanical, and structural properties of soda-lime-silicate glasses were investigated before and after K+-for-Na+ ion-exchange strengthening. The increase in Al2O3 content resulted in increased glass network polymerization and decreased compactness. The pristine glasses showed an increase in T(g), H, and E(r) with increasing Al2O3 content, while the chemically strengthened glasses exhibited a linear dependence. Solid-state NMR revealed the presence of AlO4 groups in both types of glasses. The CS glasses had lower K+-for-Na+ ion exchange ratio compared to the soda-lime-silicate glass. Differential thermal analysis of CS glasses showed a blurred T(g) and an exothermic step below T(g). The hardness of the CS glasses at low loads and n(M O-(2))/n(Al2O3) & AP; 1 suggested increased elastic energy recovery and glass compactness.

Summary: Thin film polyethylene oxide, produced by the thermal evaporation technique, exhibits structural and property differences compared to bulk polyethylene oxide. The dielectric constant of polyethylene oxide thin film is 10 times greater than that of bulk polyethylene oxide. There is consistency among dielectric constants, activation energies, and free volume fractions for both thin film and bulk samples. Polyethylene oxide thin film is observed to be more brittle than bulk polyethylene oxide.

Summary: Although molecular dynamics (MD) simulation is a powerful tool for investigating the atomic-scale structures of complex materials, its reliable and accurate application to multi-component glass systems faces challenges due to limited force fields (FFs) and the complexity of chemical environments. This study demonstrates the feasibility of efficient and accurate large-scale density functional theory (DFT) calculations for multi-component glass systems. The evaluation of classical FFs based on the results of large-scale DFT calculations reveals low accuracy for non-bridging oxygen atoms, and differences in Si-O-Si angle distribution and electronic structure for X = Mg.

Summary: In this study, vanadium oxide xerogel samples were successfully synthesized through a liquid phase reaction and the interaction of films with water. The samples were thoroughly analyzed using X-ray diffraction and Raman spectroscopy, revealing the existence of two distinct phases. It was also discovered that previous misinterpretations regarding the high-pressure polymorph structure were due to the formation of a high-temperature phase. These findings highlight the potential for further refining and expanding the current structural models of vanadium oxide xerogel in future research efforts.
