In this study, a glass system was fabricated by adding varying concentrations of MoO3. The optical features, thermal properties, and radiation shielding ability of the glasses were examined. It was found that the addition of MoO3 can alter the optical and thermal properties of the glasses, as well as improve their radiation protection applications.
The glass system 42.5P(2)O(5)-42.5B(2)O(3)(15 - x) Li2O-x MoO3 x = (0, 2.5, 5.10 and 15), was fabricated using a melt-quenching technique. Optical features are examined depending on measuring the absorption and transmission of the prepared glasses. The energy gap (E-opt), increases from 2.23 to 2.49 e.V. Urbach (E-u), decreases from 0.513 to 0.5 e.V. Basicity, polarizability, electronegativity, and some physical constants are determined. The temperature of the glass transition T-g, increases from 493 to 532 degrees C, the temperature of onset glass crystallization T-c increases from 493 to 532 degrees C and the temperature of the crystallization T-p increases from 606 to 636 degrees C. Radiation shielding properties have been examined by Phy-X / PSD. The impact of adding MoO3 to the glasses on their shielding ability was investigated. The lower value of the (MFP) sample has been detected at a higher MoO3 concentration and it is good radiation attenuation glasses. For radiation protection applications, the investigational glasses had superior characteristics.

Broadband dielectric relaxation investigations of polyvinyl chloride-fGO nanocomposite films

Z. A. Alrowaili, R. M. Ahmed, Ahmed Saleh, Abdelazim M. Mebed, T. A. Taha

Summary: The dielectric properties of PVC-fGO films were studied in different temperatures, showing that the high dielectric constant values at low frequencies in different nanocomposites were induced by the space charge effect from electrode polarization. The maximum barrier height decreased with increasing temperature and was independent of the fGo content. The real dielectric modulus decreased with increasing fGO content, while the AC conductivity increased up to 0.3 wt% of fGO and then decreased.

Effect of La2O3 Concentration on the Structural, Optical and Radiation-Shielding Behaviors of Titanate Borosilicate Glasses

Kh. S. Shaaban, B. M. Alotaibi, El Sayed Yousef

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: The physical, structural, mechanical, optical, and radiation characteristics of glasses with different PbO content were investigated. It was found that as the PbO content increased, the density increased, molar volume decreased, mechanical moduli improved, indirect band gap values decreased, and Urbach energy increased. Moreover, the shielding characteristics and effective removal cross section of the glasses also changed with increasing PbO level.

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: A glass system was manufactured by substituting CeO2 for ZnO in concentrations ranging from 0 to 1 mol% in the glass matrix. The mechanical parameters and elastic characteristics of the glass system were evaluated using the Makishima-Mackenzie model and sound wave velocity measurements, respectively. The results showed that increasing CeO2 doping ratio enhanced the density, sound velocities, elastic properties, and microhardness of the glass. The replacement of ZnO with CeO2 improved the shielding capacity of the glass.

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.

Summary: This study prepared borate glass systems containing lanthanum oxide (La2O3), nickel oxide (NiO), and sodium oxide (Na2O) using the melt quenching technique with varying La2O3/B2O3 contents.
