“…The increase in G t is also related to the replacement of the SiO 2 (G i = 68 kJ/cm 3 and V i = 14 cm 3 /mol), CaO (G i = 64.1 kJ/cm 3 and V i = 9.4 cm 3 /mol), Na 2 O (G i = 31.9 kJ/cm 3 and V i = 11.2 cm 3 /mol), and MgO (G i = 90 kJ/cm 3 and V i = 7.6 cm 3 /mol) by Sb 2 O 3 (G i = 35.3 kJ/cm 3 and V i = 23 cm 3 /mol) [27], and Al 2 O 3 (G i = 131 kJ/cm 3 and V i = 21 cm 3 /mol). The mentioned values of the dissociation energy are related to the standard heat of formation (enthalpy) for each constituting compound, which is described by Equation (2).…”

“…As illustrated The mean free path (MFP) is used to predict the average distance between two gamma collisions. We can connect the MFP with the HVL via the relationship (MFP = HVL ln (2) ). Thus, the MFP's estimated values have a similar trend and discussion, as presented in the HVL section (see Figure 11).…”

“…Various glass-based systems have their own medical, industrial, and technological applications due to their intrinsic magnetic, optical, physical, structural, and mechanical features. These properties, in principle, can be measured in house-based laboratories due to their ease of modification and access for certain experimental setups [1][2][3][4]. On the other hand, radiation-matter interactions may be best performed at synchrotron-based facilities such as the Deutsches Elektronen-Synchrotron (DESY) (Hamburg, Germany), European Synchrotron Radiation Facility (ESRF) (Grenoble, France), or National Synchrotron Light Source (NSLS) (Brookhaven, NY, USA).…”

Elastic moduli were theoretically computed using the Makishima–Mackenzie model for SiO2–Na2O–CaO glasses doped with Sb2O3 contents. The calculated elastic moduli (Young’s, bulk, shear, and longitudinal modulus) were observed to increase with an increase in the Sb2O3 contents. The microhardness showed an increase, while Poisson’s ratio decreased with the rise of the Sb2O3 contents. In addition, gamma-ray and neutron shielding parameters were evaluated for the investigated glasses. The linear attenuation coefficient (LAC) was simulated using the Monte Carlo N-particle transport code (MCNP-5). Other parameters, such as the mass attenuation coefficient (MAC), transmission factor (TF), and half-value layer, were calculated based on the simulated LAC. The addition of Sb2O3 content was observed to enhance the investigated glasses’ shielding parameters, where the highest LAC was achieved for the SCNSb10 glass with 10 mol% Sb2O3 and decreased from 0.441 to 0.154 cm−1 at gamma energies between 0.248 and 1.406 MeV. Furthermore, the fast neutron effective removal cross-section (∑R) was computed theoretically. The calculated results showed that the highest ∑R was equal to 0.0341 cm2g−1 and was obtained for the SCNSb0 glass, which had no Sb2O3 content, while the lowest ∑R was equal to 0.0286 cm2 g−1 for the SCNSb10 glass sample. The present work was carried out to examine the advantages of the soda–lime glasses with different Sb2O3 contents in several photon shielding applications, especially for radiation safety in nuclear installations.

“…From the perspective of lithium-zinc-added glass systems, we come forward numerous studies on radiation shielding properties [23][24][25]. Moreover, silicate-based glass systems are of interest by many researchers for doping and adding various oxide contents [26][27][28]. As can be appreciated from the literature works, no further investigations have been made on LZS or LZCS glass systems.…”

In this study, a preliminary theoretical investigation on lithium-zinc-calcium-silicate (LZCS) glass with a composition of (15-x)Li 2 O-10ZnO-10CaO-65SiO 2 -xB 2 O 3 where x: 0, 3, 6, 9, 12, and 15 mol% was performed to understand the effect of B 2 O 3 on physical, optical, and radiation shielding properties. For this purpose, the L15B0 to L0B15 glass series was designed for evaluating glass density (ρ glass ), refractive index (n), mass attenuation coefficient (µ m ), and half-value layer (Δ 0.5 ) parameters. The theoretical calculations showed that the increasing amount of B 2 O 3 increased the overall ρ glass from 2.9195 to 2.9865 g/cm 3 . Further, the addition of B 2 O 3 in substitution for Li 2 O enhanced the n parameter from 1.6882 to 1.7626. Additionally, BatchMaker software aided to investigate viscosity behavior with the increasing temperature. We found out that the melting point of LZCS glass series ascends with the addition of B 2 O 3 , namely from 1309 to 1624 ºC. On the other hand, the newly developed Phy-X/PSD software computations paved the way for ascertaining µ m and Δ 0.5 . According to the µ m computations, one can clearly state that an increasing trend is observable against the increasing photon energy, but the L0B15 possessed an enhanced shielding ability than that of the remaining at all photon energies. Moreover, we found out that the Δ 0.5 increased with respect to the ascending photon energies, however, the Δ 0.5 was effectively improved with the addition of B 2 O 3 in the order of L0B15
