“…As the monovalent cation is incorporated into the glass network, the Ca 2p level shifts to the lower BE due to the formation of higher nonbridging oxygen formation. 41 The O 1s peaks ascribes the formation of bridging and nonbridging oxygen, thereby confirming the presence of covalent bond between two SiO 4 tetrahedron (BO) and one SiO 4 tetrahedron (NBO). In general, the BO evolution is recognized at 532 eV, whereas BG devoid of Na + exhibits higher BO bridging by projecting a strong peak at 533.24 eV as shown in Figure 6i, and as the monovalent cation is incorporated, NBO dominates the BG glass structure that are in consistent with FTIR and Raman analysis.…”

The 45S5 bioglass uttering Class A bioactivity promotes both osteoconduction as well as osteoinduction. Though one of the higher reactive bioactive materials known with structural and physiological influence upon ionic modulation, poor mechanical properties are perceived. The possible solution to overcome the weak stability is to choose material's composition that provides retained bioactivity and improved mechanical stability. Meanwhile, primary burst out of Na + ions increases the local pH, harms cell life, and acts as a well-known disruptive modifying species that weakens the bioactive glass network, decreasing network connectivity, showing faster degradation and lowering mechanical stability. Therefore, in this study, more detailed systematic exploration on structural influence of sodium monovalent cation and its behavior on physiological environment was genuinely studied and reported that bioactivity of the bioactive glass can be highly achieved even without Na + ions. The result exhibits benefits of sodium free bioactive glass (denoted as No Na + BG) over Na + BG and exhibits improved mechanical stability and also possible degradability, having in-built apatite phase even before immersion in simulated body fluid (SBF). Also, sodium free bioglass proved as a superior candidate for erythrocyte compatibility with rapid clotting tendency on interaction with blood and a promising replacement for 45S5 bioglass in all aspects especially in mechanical stability view, which can withstand more than 5 months in phosphate buffer saline (PBS).

Tuning the concentration of nanoparticles (NPs) to accommodate wider application demanded a better understanding of the physicals and structural properties of the glass. A series of zinc phosphate glasses with the composition of (57-x) P2O5- 40ZnO-3Tb2O3 –xCuO, (0 ≤ x ≤ 2 mol %) has been prepared by melt quenching technique and their physical and optical characterization have been studied. The X-Ray Diffraction technique and UV-Vis Spectroscopy have been used to characterize the glass sample. The XRD confirms the amorphous nature of the prepared glasses. The physical properties of glasses with different CuO NPs such as density, molar volume, refractive index and electronic polarizability are determined. It is found that both density and molar volume decreases with increasing CuO NPs concentration. The optical band gap (4.54 eV-2.96 eV) and the Urbach energy (0.19 eV-0.54 eV) are showing a decreasing trend with the increasing amount of CuO NPs.This is due to the formation of non-bridging oxygen, (NBO) in the glass network. The glass exhibits high refractive index ~2.40 and polarizability ~1.12 ×10-23 cm3 and is useful for solid-state laser and optoelectronic devices.

In this study, a novel aluminum phosphate (AlPO4) heat‐resistant layer reinforced with aluminum silicate fiber (ASF) was successfully compounded on a poly(ether sulfone) (PES) matrix via the preparation process of high‐temperature heat treatment and vacuum hot‐pressing sintering technique. The influence of the ASF content on the morphology, thermal, mechanical, and dielectric properties of the as‐fabricated aluminum silicate fiber reinforced aluminum phosphate–poly(ether sulfone) (ASF/AlPO4–PES) layered composite was investigated. The results reveal that the incorporation of aluminum silicate fiber/aluminum phosphate (ASF/AlPO4) heat‐resistant layer can significantly improve the thermal stability and mechanical performances of the PES matrix composites. Compared with the pristine PES, the ASF/AlPO4–PES layered composite containing 8.0 wt % ASF exhibited better high‐temperature resistance properties (300 °C) and a lower thermal conductivity (0.16 W m−1 K−1). Furthermore, the dielectric constant and dielectric loss tangent of this PES matrix composite decreased to 2.16 and 0.007, respectively. Meanwhile, the frequency stability of the dielectric properties for the ASF/AlPO4–PES layered composites was remarkably enhanced with increasing ASF addition at frequencies ranging from 102 Hz to 5 MHz. This was attributed to the existence of microscopic pores within the ASF/AlPO4 layer and the strong interfacial bonding between the ASF/AlPO4 layer and the PES matrix. © 2017 Wiley Periodicals, Inc.
