The new technique of atomic-scale X-ray Photon Correlation Spectroscopy (aXPCS) makesuse of a coherent X-ray beam to study the dynamics of various processes in condensed matter systems.Particularly atomistic migration mechanisms are still far from being understood in most of intermetallicalloys and in amorphous systems. Special emphasis must be given to the opportunity to measureatomistic diffusion at relatively low temperatures where such measurements were far out of reach withpreviously established methods. The importance of short-range order is demonstrated on the basis ofMonte Carlo simulations.

In this research, the effects of Ba0.7Sr0.3TiO3 (BST) on optical and dielectric properties of Na2O-B2O3-SiO2 glasses were investigated. From the study, the optically transparent glass from BST system was successfully prepared by using melt-quench method. The composition of BST used in this study are ranging between 20-60 wt.% BST. It was found that the addition of BST enhanced conductivity, but in turn reduced the percentage of transmittance in the glasses. The dielectric constant (ɛr) of the BST/Na2O-B2O3-SiO2 glasses improved with increasing the content of BST, which in turn plays an important role in controlling the properties of the BST/Na2O-B2O3-SiO2 glasses.

Abstract Glasses with the chemical composition of 52B2O3 – 12SiO2- 26Bi2O3 – (10 - x ) TiO2 - xY2O3, : (0 ≤ x ≥ 10 )prepared using the melt-quench method. The goal of this study is to investigate the structural, thermal, and crystallization characteristics of these samples. XRD analysis has explored the nature of the glass system. Molar volume obtained reduced while the density denotes increased in the present system. FTIR analysis revealed that as Y2O3 replaced by TiO2, because of an increasing trend in bridging oxygens (BOs), structural units and interconnection of modifier oxide tetrahedral increment, while non-bridging oxygens (NBOs) reduce. These glasses' thermal stability investigated using DTA. As the concentration of Y2O3 increased, so the thermal parameter values. The glass-ceramic denoted prepared under controlled heat and investigated using XRD & SEM. Ultrasonic velocities and elastic moduli of glass-ceramic samples increase as internal energy increases. The significance of Y2O3 modifier in the glass system signifies proved. Y2O3 is a powerful nucleating agent that can cause crystallization, assisting in the formation of glass-ceramic phases.
