Summary: Topological constraint theory is extensively used to describe how the composition and structure of glasses and glass-forming melts control their properties. A generic method based on molecular dynamics simulations has been proposed to predict the onset temperature below which constraints become active, and the difference in onset temperatures largely governs the fictive temperature of glasses.

Summary: The study reveals that Si-rich C-A-S-H gels tend to be homogeneous, while Al-rich C-A-S-H gels tend to phase-separate. This transition is correlated with a topological flexible-to-rigid transition within the atomic network. The propensity for topologically-overconstrained gels to phase-separate arises from internal stress within their atomic network.

Summary: Phosphate glasses for bioresorbable implants exhibit varying dissolution rates based on composition, with a proposed new mechanism involving a two-stage dissolution process influenced by lower Ca concentration and solution pH. This new mechanism suggests an initial diffusion-controlled formation of a conversion layer, followed by rate-limiting layer dissolution reactions once the layer is stabilized. These findings provide insight into the dissolution mechanisms of P2O5-CaO-Na2O glass, particularly regarding the transition between the two dissolution stages.

Summary: In order to improve the hypergolic ignition properties of ionic liquids (ILs), a new design strategy of hypergolic coordination compounds (HCCs) was demonstrated. Eight HCCs were synthesized and characterized, showing excellent hypergolic ignition properties that could be modulated by changing the metal, ligand, and anion components. The copper-based HCCs exhibited the best performance among the new hypergolic materials, significantly reducing the ignition delay time of the IL system.

Summary: This study investigates the initial dissolution rate of multicomponent glasses to evaluate the impact of increasing magnesium content on the alteration process and compare the behavior of calcium- and magnesium-bearing glasses. The results suggest that substituting calcium for magnesium reduces the initial dissolution rate, while increasing magnesium content leads to an increased dissolution rate. The analysis with topological constraint theory indicates that the magnesium environment is better defined than calcium or sodium, possibly acting as an intermediate species.

Summary: Based on molecular dynamics simulations, we investigate the relationship between the ductile-to-brittle transition of oxide glasses and the connectivity of the atomic network. We find that the transition is caused by the percolation of stressed-rigid atomic clusters. Additionally, our analysis shows the plastic dynamics of oxide glasses are similar to that of supercooled liquids, exhibiting strong correlations and spatial heterogeneity.

Summary: Previous research has mainly focused on the flow dissolution of complex glasses like those used in nuclear waste encapsulation, while this study specifically examines the effect on lithium disilicate glass. The results indicate that temperature and flow rate have an impact on dissolution, with flow having little effect on silicon dissolution. The higher pH in the static system increases the dissolution of silica. The overall trends are similar to previous research but differ from complex glasses.

Summary: This work demonstrates that water can depolymerize polyhedra with labile metal-ligand bonds in a cobalt-based coordination network, resulting in nonstoichiometric glasses. The addition of water molecules promotes the breakage of network bonds and coordination number changes, thereby lowering melting and glass transition temperatures. These structural changes alter the physical and chemical properties of the glass, similar to the concept of modifiers in oxides. This approach can be extended to other transition metal-based coordination networks, enabling diversification of hybrid glass chemistry.

Summary: Despite decades of studies, the nature of the glass transition remains elusive. Fragility, which describes the sharpness of dynamical arrest at the glass transition, is inversely correlated with the medium-range order structure characterized by the average medium-range distance (MRD). Low MRD values indicate an excess of unstable small network rings in glasses, which deform more readily with temperature changes and increase fragility.

Summary: Atomic structure plays a crucial role in determining the physical properties of materials, including glasses. In this study, the researchers investigated the structure-property relationships in glasses by manipulating their density and hardness through thermal-annealing and pressure-quenching processes. Neutron total-scattering patterns were used to analyze the structural changes, and the results indicated that medium-range structure changes were closely correlated with the properties, specifically hardness.

Summary: Superior flexibility and toughness can be achieved in bioactive hydrogels by using a double polymer network with complementary properties. In this study, polyacrylic acid (PAA) and sodium alginate (SA) were combined to obtain a dual-reinforced double interpenetrating network (d-DIPN) hydrogel. The reinforcement involved ionic cross-linking and introduction of SiO2 nanoparticles, leading to significant improvements in strength and toughness. Furthermore, the hydrogel exhibited swelling resistance, self-healing behavior, adhesive abilities, and shape memory performance. Despite a reduction in breakage strain and stress, the biocompatibility and bone cell proliferation ability of the hydrogel were improved through a mineralization process. Overall, this work provides a pathway for the design of strong and tough hydrogels with potential applications in biomedicine and tissue engineering.

Summary: In this study, the effects of indenter sharpness and stiffness on the indentation response of oxide glasses were investigated. The study examined the glass deformation mechanism, cracking behavior, and hardness for three different glasses using five different indenters. The results showed that increased indenter sharpness reduced the indentation size effect and lowered crack initiation resistance, while the effect of indenter material was insignificant when the indenter was stiffer than the specimen.

Summary: By simulating glassy Li2S-P2S5 electrolytes with different fractions of polyatomic anion clusters, this study reveals the structural origins of lithium-ion mobility and identifies that soft (high mobility) lithium ions are predominantly found around PS43- units, while hard (low mobility) ions are found around P2S64- units. The soft lithium-ion migration requires a smaller energy barrier to be overcome compared to the hard lithium-ion migration.

Summary: Annealed titanate glasses have a flexible network structure that can be modulated by annealing temperature, which is different from the structural changes in traditional network glasses. The rearrangement of the network in barium dititanate glass occurs in a non-monotonic, two-stage process. The irreversible change in network connectivity is attributed to the development of crystal-like cationic motifs.

Summary: Using a curated dataset of over 3,000 inorganic glasses, we developed machine learning models to predict the composition and load dependence of Vickers hardness. When tested on new glass compositions unseen during training, the standard data-driven ML model failed. To address this gap, we combined an empirical expression with ML to develop a framework called SRIMP, which outperforms the data-driven ML model in predicting the indentation size effect. The deconvolution of hardness into load-dependent and load-independent terms provides a holistic understanding of the composition effect and ISE in glasses.

Summary: The structure of zinc aluminosilicate glasses with a wide composition range was investigated using neutron and high-energy x-ray diffraction and Al-27 magic angle spinning nuclear magnetic resonance spectroscopy. The results revealed a composition-dependent structure, where four-coordinated aluminum atoms were dominant and zinc played a role as both a network modifier and charge compensator. The coordination environment of zinc varied systematically with the glass composition, influencing the coordination number and bond distance.

Summary: The role of Ga2O3 in oxide glasses is not well understood compared to other network forming oxides, so this study investigates the structure and mechanical properties of sodium gallioborate glasses and compares them to sodium aluminoborate glasses. The results show that the substitution of Ga2O3 for B2O3 increases the fraction of tetrahedral Ga units and decreases the fraction of tetrahedral B units. However, unlike in aluminoborate glasses, higher-coordinated polyhedra are not observed even in the pergallic region.

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.
