“…Kaur et al [28] reported the band being at 693 cm −1 credit to the same vibrations of B-O-B bonds. Sayyed et al [29] observed a strong bond around 635 cm −1 which is due to the B-O-B bending vibrations. Rani et al [20] reported a band around 700 cm −1 is attributed to the bending vibrations of B-O-B in BO 3 units.…”

Machine learning techniques have been employed to predict the glass densities of xBi 2 O 3 –(70 − x)B 2 O 3 –20Li 2 O–5Sb 2 O 3 –5ZnO glasses using a data set of 2000 various B 2 O 3 rich glasses using their chemical composition and ionic radius. The experimental density of present glasses strongly depends on Bi 2 O 3 content which is increasing with bismuth content. The increasing density in bismuth doped glasses because the BO 3 are converted into BO 4 units, and besides BO 3 units are less heavy than the BO 4 units. The FTIR studies also confirm that the intensity of B–O–B bond decreasing with increasing Bi 2 O 3 content which suggested that B–O–B bond in bond ring isolated to BO 3 units transformed into BO 4 units. In Raman Spectra the stretching vibrations of BO 4 units shifting towards higher wavelengths with increasing Bi 2 O 3 content. This shifting conforms that there is a structural changes in the glass-matrix and borate units converting from BO 3 to BO 4 units. The prepared glasses along with B 2 O 3 rich glass data set train on various AI model such as gradient descent, Random Forest regression and Neural Networks to predict present density of glasses. Among the various models RF regression analysis model is successfully acceptable for the glass data with the highest R 2 value 0.983 which end result conform that the predicted and experimental values correlated. ANNs stood the effective technique in prediction of glass density with the optimum performance resulting with Tanh as the activation function (R 2 = 0.950). The minimum cost 0.018 obtained in the case of gradient decent function which also shows the better performance of regression model.

Due to the low melting temperature, the glazes based on the Bi2O3-B2O3-ZnO system are used as coatings on the surface of industrial glass substrates. Moreover, the composition of these coatings does not contain PbO, meeting the optical and environmental properties requirements. In this study, TiO2 was used in the Bi2O3-B2O3-ZnO glaze system to improve its photocatalytic ability. This can be considered a four – component glass system Bi2O3-B2O3-ZnO-TiO2. The heating microscopy results show that the melting temperature of the glaze system is 606 °C. The Fourier transform infrared spectroscopy results show that the TiO2 polyhedra are located independently in the structure without participating in forming a glass network. Thanks to that, the photocatalytic properties of TiO2 are maintained. The X-ray diffraction patterns results show that the formed TiO2 nanocrystals are rutile and anatase crystals. The results of determining the band gap energy using UV-Vis show that the band gap energy of the base glaze system increases with the addition of TiO2. The methylene blue decomposition results also showed that the ability to decompose organic increased when TiO2 was added to the glaze coating. The characteristics such as melting temperature, microstructure, and photocatalytic capacity of Bi2O3-B2O3-ZnO-TiO2 white glazes (5 and 10 % weight of TiO2) also were indicated in this paper.

“…Generally, lead (Pb) and concretes used to be standard materials for the radiation protections owing to its advantages demonstrated as the high-density material, which become the main property improved to attenuate the high-photon energy [4,5]. Unfortunately, both lead (Pb) and concrete are opaque materials, and toxicity to the creature's DNA is stored in the nucleus of a cell [1,4,6]. However, glass is one of the materials that showed the high-transparent property and improved density by varying chemical composition, which K. Singh, M.I.…”

The radiation shielding properties and fast neutron removal cross-sections of Na2O-Gd2O3-Al2O3-P2O5 glass system doped with Dy3+ were calculated by theoretical approach using the Phy-X program. However, charged particles were simulated via SRIM coding. The result found that density and molar volume of the samples increase with increasing of Dy2O3 concentrations. For radiation shielding properties, increasing Dy2O3 concentrations impact with the mass attenuation coefficient (MAC), effective atomic number (Zeff), and effective electron density (Neff) and also corresponds to the gamma energy ranges. In other hands, increasing density and the MAC are not result directly with neutron cross-sections. For charged particles, the total mass stopping power (TMSP) of both particle as proton and alpha particles depend on the medium that charged particles traversed and also rely on number of ions. HIGHLIGHTS Calculate and analyst the rediation shielding parameters by Phy-X program. The charged particles were simulated via SRIM coding.
