“…However, S5 sample showed minimum transmission behavior at all the glass thicknesses used. According to previous studies in the literature, increasing the percentage of Bi 2 O 3 in the glass composition may be an efficient solution of reducing the gamma radiation incidence on the material [38][39][40][41]. The findings of this study, which contributed to past studies, also indicate that glass structures with a larger Bi 2 O 3 contribution had a higher density and hence better gamma ray reduction capabilities.…”

The main objective of the present work was to assess the gamma radiation shielding competencies and gamma radiation transmission factors (TFs) for some tellurite glasses in the form of Bi2O3–TeO2–Na2O–TiO2–ZnO. MCNPX general-purpose Monte Carlo code (version 2.6.0) was utilized for the determination of TF values at various well-known radioisotope energies for different glass thicknesses from 0.5 cm to 3 cm. Moreover, some important gamma ray shielding properties were also determined in the 0.015–15 MeV energy range. The results show that glass densities were improved from 5.401 g/cm3 to 6.138 g·cm3 as a function of Bi2O3 increment in the glass composition. A S5 glass sample with the maximum Bi2O3 additive was reported with superior gamma ray shielding properties among the studied glasses. It can be concluded that Bi2O3 can be used as a functional tool in terms of improving glass density and, accordingly, gamma ray shielding attenuation properties of tellurite glasses, where the role Bi2O3 is also critical for other material properties, such as structural, optical, and mechanical.

In this work, the structural, optical, ligand field and antibacterial properties of Cr2O3, ZnO and Na2O borosilicate glasses were studied. A glass system of the compositions 70B2O3-14.8 SiO2-(15-x)Na2O-0.2Cr2O3-xZnO, where x = 0, 3, 5 and 7 mol% were prepared via melt-quenching technique. In this study, X-ray diffraction (XRD) spectra were used to check the amorphous state of the prepared glass specimens. Infrared (IR) spectra were used to study the internal structure of the formed units and groups within the glass matrix. Moreover, the optical absorbance spectra were used to study the optical parameters such as optical band gap (Eg), Urbach energies (EU) and ligand field parameters (10Dq, B, Dq/B and β). Furthermore, the antibacterial activities of the glass samples were investigated against different antibiofilm activities for example, Staphylococcus aureus and Escherichia coli. However, the fixed Cr2O3 concentrations, IR results showed the gradual conversion of Cr3+ cations’ coordination from octahedral (CrO6; glass modifier) to tetrahedral (CrO4; glass former) with more replacement of Na2O by ZnO. This result confirms the significant influence of the environment on Cr cations’ coordination. While the optical studies showed that, Eg values increased from 3.06 to 3.62 with further ZnO doping. Furthermore, 10Dq values increased and B values decreased with the increase in ZnO content. These 10Dq increased values reflect the increased interactions between the Cr3+ cations and their environments, such as oxygen anions. Further, the decreased values of B refer to the tendency of the bonds of Cr3+ cations and their environments toward the covalent nature. On the other hand, the results showed that the investigated glasses are promising materials owing to high antibacterial activity on a large scale (food covering, wound curing, and surface coatings), especially the glass sample that contains the highest concentrations of ZnO.

“…The boron oxides have unique properties that give them stability allowing experimentation with a broader selection of elements in the composition of borate glasses and, consequently, more control over variations in performance characteristics [4]. The novel aluminoborosilicate glass reinforced with varying amounts of Bi2O3 content was explored [5]. where in the B 2 O 3 vitreous, an unusual mesostructure consists of borax rings composed of BO3 triangles.…”

Lead borate glasses of the system 25PbO-(75-x) B2O3-xCuO (x = 0, 0.025, 0.05, and 0.1) in mol.% were synthesized via the traditional melt quenching method abbreviated as (BPbCu0, BPbCu1, BPbCu2, and BPbCu3) respectively. XRD diffraction confirmed the amorphous nature of the samples. According to FTIR spectroscopy, the function groups (BO3 and BO4) and the fraction of boron tetrahedral units (N4) were determined. The density, molar volume, packing density, and some other physical parameters were calculated and discussed. The density was increased by incorporating CuO as a substitution for B2O3, while the molar volume was decreased. The ion concentrations of Cu, inter-nuclear distance, field strength, and polaron radius were also computed. The optical absorption study suggested that the copper ions exist in the Cu2+ and act as a modifier by increasing the disorder in the glass network. Hence, the present glass behaves as a bandpass filter in the UV-Vis. region. The radiation shielding properties of the as-prepared samples were theoretically calculated using the Phy-X program at energies ranging from 0.015 to 1.5 MeV. The linear and mass attenuation coefficients, as well as the half-value layer (HVL) and exposure buildup factor (EBF), have been evaluated. The results revealed that shielding parameters are affected by CuO concentrations and photon energy. Based on the results presented in the manuscript, the glass sample with 0.1 mol% CuO doping (BPbCu3) showed the best properties overall for optical and radiation shielding applications. Specifically, BPbCu3 had the highest density, refractive index, optical dielectric constant, and radiation shielding parameters such as linear attenuation coefficient and half value layer among the glass samples. The addition of 0.1 mol% CuO introduced Cu2+ ions which acted as network modifiers, increasing the disorder in the glass structure. This in turn enhanced the optical bandgap as well as the shielding capabilities against gamma radiation.
