Summary: The study investigated the effects of irradiation on sodium borosilicate glasses and International Simple Glass (ISG), revealing the saturation of hardness, modulus, and volume changes at a certain irradiation dose, and a significant increase in crack initiation resistance (CR). The structural changes in borosilicate glasses were also examined, showing a transformation of BO4 to BO3 groups upon irradiation with heavy ions. These findings suggest the importance of boron structures in controlling the macroscopic radiation effects on glasses.

Summary: In this study, borosilicate glasses were doped with strontium oxide and zirconium dioxide to simulate the effect of beta decay on vitrified materials. The structural changes were characterized using various techniques. The results showed that the increase in zirconium dioxide concentration led to a decrease in hardness and modulus, an increase in [BO3] units, and a decrease in Si-O-Si bonds. It was concluded that the real effect of beta decay cannot be accurately simulated by external electron irradiation alone and the changes in composition caused by the decay should not be ignored.

Summary: The electron irradiation effect on borosilicate glass was studied using ToF-SIMS and XPS techniques. The results showed that the amount and depth of element decrease in the irradiated surface layer were different among the samples, which was related to the glass composition. XPS analysis revealed an increase in network polymerization and transformation of boron coordination in the irradiated surface layer. These findings are important for understanding the changes in surface behavior caused by strong ionizing radiation.

Summary: This study investigates the mechanical property changes in Na2O-B2O3-SiO2 glasses with different compositions before and after irradiation with He ions. The results show that the hardness decreases and reaches saturation after irradiation, while the modulus only shows a slight decrease. The effect of irradiation varies with the composition of the glasses. Additionally, sequential irradiation with He ions can lead to damage recovery in glasses pre-irradiated with Au ions.

Summary: A new testing system and techniques have been developed to measure the hardness of materials at very high indentation strain rates. The system includes a laser interferometer that records indenter displacements at a frequency of 1.25 MHz, allowing for the determination of indentation load-depth curves and hardness. The system was used to study the behavior of fused silica and aluminum, showing that the hardness of fused silica is insensitive to strain rate, while the hardness of aluminum increases significantly at high strain rates.

Summary: The addition of alkali ions lowers the yield stress and changes the pressure dependence of shear modulus in multicomponent borosilicate glasses. Shear-induced densification is observed in both glasses, with 5-coordinated Si being the dominant mechanism for densification at high pressures. Boron atoms tend to experience plastic deformation in Borofloat 33, while plastic deformation occurs around alkali-rich regions in N-BK7, indicating different atomic-scale deformation mechanisms in these two glasses.

Summary: This study examined the correlation between the corrosion mechanism and glass composition by comparing the leaching properties of irradiated sodium-borosilicate (NBS) glasses with varying K values. It was found that heavy ion irradiation accelerated the initial Si dissolution rate and there was a strong correlation between the initial dissolution rates and the K value and proportion of Na. The study concluded that the variation trend in the initial dissolution rate of Si and Na differs under ion radiation.

Summary: The study investigates the effect of different valence states of vanadium ions on the optical properties of V, Eu doped sodium borosilicate glasses. The results show that varying vanadium concentrations in the glass influence absorption and emission characteristics, with different ions causing shifts in absorption edge wavelengths and altering emission intensities. The presence of V4+ is found to play a quenching role, affecting the emission of both Eu3+ and V5+ in the codoped glass samples.

Summary: Eu2+-doped SiO2-SrO-B2O3 glasses exhibit broad luminescence band with 0.4 mol% Eu2+ being the optimum doping concentration. The absorption and emission spectra show redshift with increasing Eu2+ concentration, while concentration quenching occurs due to electric dipole-dipole interaction. The luminescence intensity decreases with increasing temperature and the chromaticity shift is lower than Eu2+-doped commercial phosphors.

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: In this work, the size effects in spherical contact were investigated using a modified couple stress elasticity theory. A model to describe the stiffening effects of couple stress on contact load and the modulus model for size effects in spherical contact tests were proposed. The validity of the modulus model was demonstrated by comparing model results with experimental data.

Summary: The extent of glass dissolution is influenced by time, temperature, solution chemistry, and the glass composition. This study investigated the impact of different components on glass durability and found that the amount of B2O3, CaO, and Na2O had the largest effect on the dissolution process.

Summary: By combining atomistic modeling and experimental techniques, the study investigates the structural and elastic parameters of sodium borosilicate glasses, including changes induced by irradiation. The results show a linear relationship between Young's modulus and material density, as well as matching boron speciation with elemental glass composition-based models. The simulations of irradiation reveal changes in B-[4] content and provide insights into the atomic-scale structural evolution of irradiated borosilicate glasses.

Summary: This study fabricated a series of sodium borosilicate glasses doped with cesium and simulated the nuclear transmutation effects due to beta decay by substituting for cesium with barium. The results showed that the substitution of barium for cesium increased the density, hardness, and modulus of the glasses, and changes were observed in the infrared spectra and NMR spectra. The comparison with previous strontium-doping work demonstrated that the nuclear transmutation effect of cesium is completely opposite to that of strontium.

Summary: This study investigates the radiation effects in equiatomic FeCrNi and FeNi compared to elemental Ni using molecular dynamic simulations. The anisotropy of threshold displacement energy (Ed) distribution is a common feature in all three materials. However, there are distinctive differences in defect behaviors between CSAs and elemental Ni, starting from defect creation to accumulation in cascade processes. The physical processes involved include atomic collision, heat dissipation, and atomic diffusion. These findings are important for designing radiation-tolerant materials by understanding the genesis of defect morphology in CSAs.
