X-ray Absorption Fine Structure (XAFS) spectroscopy has been widely used to characterize the short-range order of glassy materials since the theoretical basis was established 45 years ago. Soon after the technique became accessible, mainly due to the existence of Synchrotron laboratories, a wide range of glassy materials was characterized. Silicate glasses have been the most studied because the...

Abstract Binary glass systems of the chemical composition 0.25Li 2 O–0.75B O 3 and 0.25LiF–0.75B with different additive ratios V 5 were prepared using melt-quenching method. Characterization was carried out through techniques such as Fourier-transform infrared (FTIR) ultraviolet–visible absorption (UV–visible) spectroscopy. Optical electrical properties have been investigated in order to recog...

This manuscript deals with the preparation and detailed physical structural study of B2O3-CdO-Al2O3-PbF2 glasses reinforced MoO3 ions. With addition MoO3, density band gap values decreased while refractive index increased, confirming transformation Mo6+ ions to Mo5+ resulting in generation NBO's these glasses. The FTIR spectra revealed presence different borate aluminate units. also indicated c...

The structural aspects of xCs2O-(1-x)B2O3 glasses have been investigated by molecular dynamics as functions of Cs2O content (x=0.2, 0.3, and 0.4) and temperature (T=300 and 1250 K). The tetrahedral (BØ4-) and triangular (BØ3,BØ2O-, and BØO2 (2-)) short-range order borate units were found to be the structure-building entities of the simulated glasses [Ø=bridging oxygen (BO) and O-=nonbridging ox...

The objective of this study was to examine the proliferation and differentiation behaviors of different compositions of strontium-containing (from 0-12 mol%) borate glasses with mesenchymal stem cells (MSCs). The Cell Counting Kit-8 (CCK-8) assay revealed that after three days of culturing, the 6Sr group had the highest cell growth rate. Analysis of cell morphology revealed that cells prolifera...
