Summary: Silver phosphate glasses were studied for conditioning of radioactive iodine 129, with Nb2O5 and Bi2O3 as crosslinking agents. The impact of these modifications on glass chemical durability, especially the addition of Nb2O5, was significant in reducing phosphorus release rates and forming a passivating layer in long-term alteration tests. The results suggest that elemental release in solution alone may underestimate alteration rates, emphasizing the importance of considering different elements in glass composition.

Summary: The study explores the impact of composition on crystallization and chemical durability in alkali aluminoborosilicate glasses designed in different regimes. Peraluminous glasses exhibit the highest dissolution rates, while increasing B2O3 content can suppress nepheline formation but may have a detrimental impact on durability. The thermal history is also shown to significantly affect the durability of the glasses.

Summary: The gradual substitution of Fe2O3 by Al2O3 in polyphosphate glasses influences the thermal properties, providing valuable information for researchers to plan vitrification processes for radioactive waste immobilization. Analysis of DSC curves and X-ray diffraction patterns can help design materials with different levels of crystallinity and phase composition. The conclusions drawn enable the selection of glass with optimal Al2O3 and Fe2O3 concentrations for application potential in nuclear waste immobilization.

Summary: The glass system consisting of 5Li(2)O-(40-x) Na2O-xZnO-55P(2)O(5) doped with 2 wt% (CdO + Te) exhibited excellent gamma-ray shielding properties, with LNZP6 glass sample showing the best protection among the examined glasses. The atomic cross section (ACS) and electron cross section (ECS) parameters peaked at 0.015 MeV and decreased with increasing photon energy for all samples. The effective atomic number (Z(eff)) values were highest at 0.04 MeV for LNZP0-LNZP6, indicating the potential for efficient gamma-ray protection.

Summary: Sodium aluminium phosphate (NAP) glass has been found to be an optimal choice for immobilizing minor actinides. The addition of rare-earths and Al2O3 significantly modifies the structure of the glass. Increasing dopant concentration improves the glass's melting point, glass transition temperature, and thermal stability, while decreasing its fragility. The addition of rare-earths enhances the strength of the glass up to a certain concentration, beyond which the rigidity of the structure decreases.

Summary: Understanding the impact of individual compositional components on the devitrification of complex multicomponent glasses is important for generating transferrable knowledge. In this study, exploratory data analysis was used to analyze a heterogeneous data set of silicate glasses and determine the individual and interacting effects of cations on the crystallization of nepheline. The study showed that calculated structural glass parameters, such as field strength and cation-to-anion radius ratio, play a crucial role in nepheline's devitrification. Additionally, it was found that studies with simplified glass compositions may not provide directly applicable knowledge to complex compositions.

Summary: Commercial Chinese ink was used to disperse vapor-grown carbon nanofibers in aqueous suspensions, resulting in conductive paper-based composites with low sheet resistance and enhanced electrochemical performances. The carbon black particles helped separate the nanofibers and acted as connection points, while the glue reinforced the conduction network, showing that the composite material could be utilized as electrodes for solid-state symmetric electronic double-layer capacitors and for electrodeposition of MnO2.

Summary: In this study, the emission peak of europium (Eu) ions in borosilicate glasses is tuned by adjusting the SiO2 to B2O3 ratio and the concentration of Eu ion dopants. It is observed that the emission peak can be redshifted by increasing the content of SiO2 or by introducing Eu2O3. Cyan emission is achieved by altering the [SiO4] tetrahedra, [BO4] tetrahedra, and [BO3] triangles within the glass. The results highlight the relationship between glass network structure, Eu ion concentration, and visible light emission.

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.
