Summary: The melt-quenching route was utilized to produce phosphate glasses in the system of 20Na2O-(50-x) Na2WO4-30P2O5: xTiO2 with 0 <= x <= 25 mol%. Various characterization techniques were employed to investigate the influence of TiO2 on the physical-optical parameters of the synthesized glasses. It was found that as the TiO2 content increased, the density values decreased, while the optical band gap (Eg) decreased and Urbach energy (Delta E) increased. The placement of TiO2 in glasses was related to the creation of non-bridging oxygens. Moreover, an increase in TiO2 mol percent resulted in a decrease in optical basicity, electronic polarizability, optical electronegativity, and the electronic polarizability, as well as an increase in refractive index, dielectric constant, and optical dielectric constant.

Summary: The conceptual design of high-entropy materials is expanded to oxide glasses, and a series of LaO3/2-TiO2-NbO5/2-WO3-MOx (M = Mg/Al/Si, and x = 1, 3/2, 2) glasses are successfully synthesized. The transparent glasses possess excellent thermal stability with a glass transition temperature above 73°C. The large temperature gap ΔT, exceeding 60°C and reaching a maximum of 107°C for M = Si, is attributed to the nature of SiO2 as a network former and the complex atomic interactions resulting from high entropy. The M = Al glass exhibits the highest refractive index (n(d) = 2.33) and visible transmittance (74%), maintaining its performance after electron beam irradiation in the IR region, indicating excellent irradiation resistance.

Summary: Supercontinuum generation from alkali antimony zinc borate glasses was studied using a femtosecond laser. The optical bandgap values were determined for all glass samples. Enhanced SC generation was observed in sodium-doped glass, despite its lowest bandgap among the samples. The physical and structural parameters of the glasses were analyzed and discussed, along with the observed shift in binding energies of metal cations and oxygen anions using XPS analysis. These observations provide insight into the anomaly in the enhanced SC generation from the low bandgap sodium-doped glass.

Summary: Increasing CeO2 concentration in PbO2-B2O3-CeO2 glass system results in the conversion of [BO4] to [BO3] structural units and the formation of non-bridging oxygen ions. The decrease in N-4 fraction from 0.654 to 0.239 confirms the formation of [CeO7] structural units that require more oxygen atoms.

Summary: This investigation evaluated the structural, optical, and radiation-shielding effectiveness of glasses with the xLa(2)O(3)-(20 - x) TiO2-23SiO(2)-57B(2)O(3) formula. The addition of La2O3 content significantly increased the density, refractive index, ion concentration, and field strength. Optical spectroscopy showed that the indirect optical band gap (E-opt) decreased and the Urbach energy (E-u) increased with La2O3 content. FTIR spectra detected the conversion of BO3 into BO4 tetrahedral units. The glass sample demonstrated superior gamma radiation- and neutron-shielding performance compared to other glasses.

Summary: This study investigated a specific molybdenum borosilicate glass with the composition 61B(2)O(3) - 19SiO(2)- (20-x) MoO3-x CeO2, where x = (0 < x < 12 mol. %). DTA analysis revealed that the amount of CeO2 in the glass influenced its crystallization behavior, with an increase in CeO2 content leading to increased stability. XRD and SEM analysis identified various crystalline phases and microstructural morphologies in the glass samples. The presence of different-shaped particles was observed with increasing CeO(2) concentrations, and the ultrasonic velocities and elastic moduli also increased.

Summary: The conventional melting and annealing procedure was used to manufacture glass matrices with a nominal composition of x La2O3-(20 - x)TiO2-23SiO(2)-57B(2)O(3) and a gradual partial replacement of TiO2 by La2O3. X-ray diffraction (XRD), pulse-echo technique, and differential thermal analysis (DTA) were used to examine the effects of La(2)O(3)3 content on the TiO2-B(2)O(3)3-SiO2 glass. The results showed that the glass transition temperature increased with an increase in La2O3 content, and the elastic properties of the glass also improved.

Summary: Glasses with different BaO content in the formulation 15TiO2-70P2O5-(15-x)Li2O-xBaO (0 < x < 10 mol. %) were fabricated using the melt quenching procedure. The density of the glasses increased and the molar volume decreased with increasing BaO concentration. Ultrasonic velocities (VL & VT) increased as the amount of BaO content increased, indicating higher elastic properties. BaO content was found to be the only factor affecting the radiation shielding phenomenon in the glasses. BaO reinforcement not only increased the density of the glass compositions, but also enhanced their mechanical and gamma-ray shielding properties.

Summary: A series of phosphate glass with varying WO3 content was manufactured using the melt quenching procedure. The glasses' physical and structural characteristics were examined using XRD and FT-IR analysis. Increasing WO3 concentration led to depolymerization of the glass network and enhanced physical, mechanical, and structural parameters. Furthermore, the glass exhibited improved radiation characteristics due to the presence of stronger P-O-W bonds.
