Summary: The addition of P2O5 in lithium aluminoborate glasses results in a more open and soft network. Upon compression, the coordination numbers of boron and aluminum increase, while the number of bridging oxygens around phosphorous decreases. Glasses with higher P2O5 content show a larger decrease in bridging oxygens, leading to a larger increase in coordination numbers of boron and aluminum.

Summary: Aluminoborate glasses with a flexible network structure show high resistance to crack initiation during indentation, and aging in a humid atmosphere can further enhance this resistance, especially in cesium aluminoborate glasses. Humid aging results in increased atmospheric water permeation and the formation of a hydration layer, with a more pronounced effect on Cs-containing glasses compared to Li- and K-containing glasses. This research provides insights on controlling the humid aging rate to improve crack resistance in aluminoborate glasses.

Summary: This study focuses on the relationship between the solubility of sulfur (as SO3) and the structure of Na2O-B2O3-SiO2 glasses. The research found an inverse correlation between the sulfur solubility and the degree of network polymerization in the glasses. While the modification of SO3 can compete with depolymerization mechanisms, the conversion of BO3 to BO4 induced by alkali cations is dominant. These findings have important implications for understanding the control of sulfur solubility in borosilicate-based nuclear waste glasses.

Summary: This study correlates optical absorption and EPR spectroscopy data to understand the effect of alkali concentration on the coordination and color change of Cu2+ in binary alkali borate glasses. The results show that Cu2+ coordination remains unchanged with increasing alkali content, and the color change is limited. The distortion of Cu2+ sites is higher in low-alkali glasses, indicating a connection with rigid borate units. High-alkali glasses exhibit a more covalent character and broader absorption band. This combined approach provides insight into the local environment of Cu2+ in oxide glasses.

Summary: This study investigates aluminoborosilicate glasses with La2O3 and CeO2, examining their structural, thermal, and dielectric properties. The presence of La2O3 influences the network structure of the glass, while the presence of Q(3) and Q(4) results in a more compact structure. Changes in glass transition temperature, thermal stability parameters, and glass density are attributed to variations in bond strength, non-bridge oxygen content, field strength, and molar mass of La2O3.

Summary: The distribution of TEMPO-oxidized cellulose nanofibrils (t-CNFs) in different molecular weights of poly(ethylene oxide) (PEO) and its effect on Li+ ion mobility, bulk conductivity, and long-term stability were investigated. The results showed that in a low-MW PEO system, t-CNFs were incorporated between lamellas, while their nuclei remained particle-free. In a high-MW PEO system, the growth of t-CNFs was arrested due to the strong t-CNF network surrounding them. This study provides insights for the design of robust all-solid-state Li-metal batteries.

Summary: Complete substitution of Li atoms for Ag atoms was achieved in AgGaSe2 and AgInSe2, resulting in solid solutions LixAg1-xGaSe2 and LixAg1-xInSe2. The crystal structures were determined using single-crystal X-ray diffraction and Li-7 nuclear magnetic resonance spectroscopy, confirming unique sites for Li atoms. The structure of LixAg1-xGaSe2 retained the tetragonal CuFeS2-type structure, while LixAg1-xInSe2 transformed from tetragonal to orthorhombic as Li content increased. The optical band gaps increased gradually with higher Li content, enabling control to desired values.

Summary: This study investigates the effects of Bi substitution on the structure and properties of CsSnBr3. The results show that Bi substitution does not alter the cubic perovskite structure, but introduces disorder at the atomic level. Bi atoms randomly replace Sn atoms with no segregation. The absorption edge shifts from 1.8 eV to 1.2 eV, maintaining a direct band gap. Bi substitution improves degradation resistance by inhibiting Sn oxidation.

Summary: The rare-earth chalcogenide iodides RE (3)(Ge1-x Si x )(2)S8I (RE = La, Ce,and Pr) and Ce3Si2(S1-y Se y )(8)I were synthesized successfully. Complete solid solutions and phase-pure samples were obtained for all series, with smooth evolution of cell parameters. The substitution of Si for Ge atoms in RE (3)(Ge1-x Si x )(2)S(8)I resulted in complete disorder of the tetrel atoms, while the substitution of Se for S atoms in Ce3Si2(S1-y Se y )(8)I occurred with preferential occupation of Se atoms. The optical band gaps increased slightly or negligibly upon the substitutions in RE (3)(Ge1-x Si x )(2)S8I and dramatically decreased from 2.8 to 1.9 eV in Ce3Si2(S1-y Se y )(8)I. The photoluminescence emission shifted slightly to blue-green or significantly to green upon the substitutions, depending on the concentrations of Ge or Se. The photoluminescence intensity and lifetime tended to decrease with increasing concentration of Ge or Se. The activation energy for thermal quenching in Ce3Si2S8I was determined to be 0.68 eV.

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.
