“…The longitudinal and shear ultrasonic velocities decreased from 3737 to 3045 ms −1 and 1959.3 to 1887.8 ms −1 , respectively, as the amount of Nd 3+ NPs ions increased from 0.01 to 0.02 mol. The decrease in the ultrasonic velocities may be due to the decrease in the connectivity in the glass network caused by the increase in nonbridging oxygen (NBOs) [17].…”

The aim of this work is to determine the effect of neodymium nanoparticles concentration on the elastic properties of zinc-tellurite glass. A series of neodymium nanoparticles doped zinc-tellurite glass systems (NdNPsZT) of composition= 0.01, 0.02, 0.03, 0.04, and 0.05, were synthesized by using conventional meltquenching method. The amorphous nature of the glass system was confirmed by using XRD analysis. The density of the glass system was determined by Archimedes method. The elastic properties were calculated from the measured density and ultrasonic velocity at 5 MHz frequency. The experimental results showed that the elastic properties rely upon the composition of the glass systems and the impact of neodymium nanoparticles (Nd 2 O 3 NPs) within the glass network. The increase in ultrasonic velocities is due to the increase in rigidity and change in structural units of the glass system. The softening temperature and the microhardness increased with the increase in Nd 3+ ions concentration from 0.1 to 0.2 mol and decreased when the Nd 3+ ions concentration increased from 0.2 to 0.5 mol. Poisson's ratio and Debye's temperature decreased with the increase in the Nd 3+ ions concentration from 0.1 to 0.2 mol and increased when the Nd 3+ ions concentration was increased from 0.2 to 0.5 mol.

Glass forming ability of lone-pair semiconductors was analyzed for (x = 0, 2, 4, 6, 8, 10) system. Values of lone pair electrons L were calculated using average coordination number of valence electrons. These values were found to decrease, as the system was moving towards the rigid region. L > 3 values showed vitreous state. Deviation of the stoichiometry confirmed the chalcogen-rich region. A linear correlation was found between the mean bond energy and glass transition temperature. Chemical Bond Approach model was applied to calculate the cohesive energy of the system. A linear relationship was found to exist between the cohesive energy and the theoretical band gap, calculated using Shimakawa relation. A decrease in both parameters was explained on the basis of average stabilization energy and electronegativity of the system. The density values were found to increase and may account for higher refractive index of the system. Large Bohr radius of the Bi atom accounted for an increase in the polarizability. Other parameters viz. degree of covalency, packing density, compactness, molar volume, free volume percentage, excess volume and polaron radius were also calculated. An effort was made to correlate the effect of Bi addition to Ge12Se76 - xAs12Bixlone-pair semiconductor on the basis of the structure of the glassy matrix or the connectedness of the material.

“…Longitudinal modulus and shear modulus can be defined as an independent elastic constant which are produced by a small stress such as the elastic strain in an amorphous solid [30]. Longitudinal modulus is = 2 and for pure shear modulus it is = 2 , where and , respectively, are the longitudinal and shear velocities of the samples [31].…”

Zinc silicate (ZnO-SiO 2 ) systems were fabricated using zinc oxide (ZnO) and white rice husk ash (WRHA) with compositions of (ZnO) x (WRHA) 1−x ( = 0.55, 0.60, 0.65, and 0.70 wt.%) was symbolized by S1, S2, S3, and S4, respectively. The ZnO-SiO 2 samples were fabricated by applying the melt-quench method and the physical and elastic properties of the samples were investigated. Physical properties used in this study are density and molar volume while the theoretical elastic moduli of the samples produced were obtained using direct calculation of theoretical model compared with the experimental elastic moduli obtained by acquiring ultrasonic velocities using ultrasonic pulse-echo technique. Values of experimental elastic moduli including longitudinal modulus ( ), shear modulus ( ), Young's modulus ( ), bulk modulus ( ), and Poisson's ratio ( ) were compared with theoretical model calculated using Rocherulle's model. All the configurations of the elastic moduli obtained experimentally match very well with the configuration from Rocherulle's model but Poisson's ratio obtained experimentally differs from the values of Poisson's ratio obtained through Rocherulle's model.
