Summary: The purpose of this study is to investigate the conditions leading to the formation of flakes in glass containers and to identify the components of the suspended flakes. Results show that flakes are formed under specific temperature, pH, and solution composition conditions. The composition of the flakes was identified as a mixture of hydrates of magnesium, calcium, and aluminum silicate.

Summary: This study investigates the reaction products of alkali-activated soda-lime glass powder (SLGP) in the presence of calcium sources. The results show that the activation of SLGP with blast furnace slag (BFS) significantly reduces the compressive strength of the synthetics and forms alka-li-calcium-silicate hydrates (N-(C)-S-H gels) as binding substances. However, combining SLGP with BFS transforms the SLGP-products into cementitious C-(N)-A-S-H gels and mitigates both strength loss and swelling phenomena.

Summary: The Vickers hardness (HV) and indentation fracture toughness (KIC) of SLS glass were studied under different environmental conditions. The results show that the HV and KIC of SLS glass are affected by water-induced hydrolysis and densification ratio in different solutions. The dissolution of densified region in high pH conditions and lower crack propagation rate in low pH conditions contribute to the slight difference in KIC in extreme conditions.

Summary: This study investigated the structure of a chemically-modified glass by utilizing nanoscale-FTIR and Raman spectroscopy. The results were compared with molecular dynamics simulations, showing a correlation between spectral features and structure. Additionally, the IR active shoulder traditionally attributed to the non-bridging oxygen stretch mode was found to be correlated to perturbations in the silicate network.

Summary: Isolated Na2O dot 2CaO dot 3SiO(2) (NC2S3) single crystals were grown at temperatures above the glass transition. The enrichment of Na in the continuous solid solution upon crystallisation causes a depletion of soda in the growing interfacial diffusion zone, resulting in a change in viscosity.

Summary: The glass formation region has been determined for the soda lime germanate system, which includes both homogeneous and phase separated glasses. The homogeneous glasses exhibit behavior typical of the germanate anomaly, while the phase separated glasses' properties can be explained by considering the effect of morphology.

Summary: In this study, the in situ dynamic crystallization properties of industrial soda-lime-silica glasses at realistic processing temperatures were investigated. Unique crystalline phases were observed at lower temperatures, and high-temperature stable SiO2 polymorphs were also observed. The main predictor variables in the previously developed liquidus temperature models were found to be questionable, and a large difference between glass processing and liquidus temperatures was identified.

Summary: The study reveals that in acid solutions, the friction and wear behaviors of soda lime silica (SLS) glass are influenced by the solution pH, with the surface charge effect playing a critical role. When the solution pH is 2.5, the most severe friction and wear occur, while below or above this value, the surface charge effect reduces the extent of friction and wear.

Summary: The aim of this study is to investigate the variations in the elastic modulus of soda-lime-silica (SLS) glass after tempering. The experimental results show that the tempering process reduces the elastic modulus of SLS glass, and the reduction is related to the tempering level and glass thickness.

Summary: Physical flaws and defects on glass surfaces can reduce the mechanical strength and chemical durability of glass. The study found that the nanoscratch behavior of soda lime silica glass varies under different relative humidity conditions. Plastic deformation of the glass surface was observed to be dependent on the humidity of the external environment, which influences the subsurface deformation mode. Frictional energy dissipation at the sliding interface was identified as a key factor affecting the subsurface deformation mode.

Summary: The study investigated the influence of substituting CaO with MgO in borosilicate glasses on their chemical durability in aqueous solution. The results showed that the substitution led to a deterioration in the chemical durability of the borosilicate glass, with implications on the leaching behavior of modifier ions and the dissolution of the glass surface.

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: 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: The microscopic strain evolution and microstructural of FeCuNbSiB amorphous alloy samples were studied under both free and tensile stress annealing conditions. It was found that an amorphous-nanocrystalline structure was developed in both samples after annealing at 813 K, and the size of nanocrystals was limited by the applied stress.

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.

Summary: The relationship between the heterogeneous structure and structural relaxation in metallic glasses was explored by investigating the quasielastic and viscoelastic behavior of a Zr55Cu30Ni5Al10 metallic glass. Stress-annealing treatment was used to retain elastic strain energy, and a unique creep recovery phenomenon was observed during the reheating process. The Maxwell model was employed to qualitatively describe the mechanisms of elastic strain energy retention and release.
