Summary: This study synthesized sodium borophosphate parent glass and derived samples containing different amounts of bismuth oxide. Fourier transform infrared spectroscopy was used to investigate the samples, and deconvolution analysis technique was employed to estimate the hidden or overlapped peaks. The study found that the IR spectra showed the presence of combined PO4 and BO3+BO4 groups upon adding Bi2O3.

Summary: The demand for improved batteries drives the development of electrical energy storage (EES). Inorganic glassy materials show excellent conductivity and stable structures, making them suitable for both cathode and anode applications. The electrical properties of glasses containing Li2WO4 are evaluated, including density, molar volume, electrical conductivity, and glass transition temperature. The study finds that an increase in Li2WO4 content leads to an increase in electrical conductivity, and the ion transport in the glasses follows a correlated barrier hopping mechanism.

Summary: The structure and properties of glasses containing B2O3 were investigated. With the increase of B2O3 content, the glass transition temperature and the relative number of BO4 units decrease, while the number of BO3 units increases. Raman spectra show the presence of NbO6 octahedra in the structural network.

Summary: This study investigated the impact of WO3 on the thermal stability of glass and the properties of proton conduction and mobility. The results showed that replacing PO5/2 with WO3 increased the glass transition temperature (T-g) and proton mobility (& mu;(H)) at T-g. The increased T-g was attributed to the formation of heteroatomic P-O-W linkages, while the increase in & mu;(H) was due to the increased proton migration paths through P-O-W linkages. This phenomenon is different from the enhancement of proton dissociation from OH groups and can be attributed to the mixed glass former effect in the proton conducting glass.

Summary: In this study, the effect of nickel content in lithium borate (LiBO3) glass systems on the performance of cathode materials for Li-ion batteries was investigated. It was found that increasing the nickel content enhanced the electrochemical properties of the glass. The 0.25Ni:LiBO3 glass electrode showed the highest specific capacitance, indicating its potential as a promising battery material.

Summary: The aim of this study is to evaluate the bioactive and tribological properties of the MgO doped borophosphate glass system. The addition of MgO promotes degradation of the glass and increases its bioactivity. In terms of tribological properties, the glass sample with 3% MgO exhibited the highest hardness and the lowest wear rate. MTT assay confirmed the non-toxic behavior of the glass samples. Therefore, MgO doped borophosphate glass shows potential for bone filling and wound healing applications.

Summary: The significant enhancement in electrical conductivity in two sodium ion-conducting glass series is attributed to increased mobility of Na+ ions and the formation of easily conductive pathways through network former substitution. By utilizing 1D/2D MAS NMR techniques, structural units forming the glass network can be determined and quantified, providing insights into the local environment and linkages between these units critical for understanding the sodium ion transport mechanism.

Summary: In this study, K2O-Gd2O3-B2O3-P2O5 glass doped with Dy2O3 (Dy:KGPB) was synthesized using the melt-quenching technique. The physical, structural, optical, and luminescence properties of these glasses were characterized. It was observed that the addition of Dy2O3 increased the density, molar volume, and refractive index of the glass. The study also found that the glass absorbed photons in ultraviolet, visible light, and near-infrared regions, and exhibited strong emissions under direct Dy3+ excitation at 574 and 482 nm. The glass doped with 1.00 mol% Dy2O3 showed the highest emission intensity due to concentration quenching. Judd-Ofelt intensity parameters were calculated and used to evaluate the radiative parameters of the glass. The scintillation efficiency of the glass was found to be around 15.6%, suggesting its potential applications in solid-state lasers, LEDs, and X-ray detection.

Summary: This study investigated the influence of ZnO content on the structural and radiation shielding parameters of zinc borophosphate glass. The glass samples were prepared using the melt-quenching technique and their structural characteristics were analyzed using various techniques. The results showed that the replacement of BO4 and PO4 units by BO3 and PO4 1/2 units led to changes in the structural characteristics and an increase in non-bridging oxygen. The density increased by up to 43% and the glass transition temperature showed reduction followed by stability with the replacement of P2O5 by ZnO. The rise in ZnO content also improved the radiation attenuation parameters, making the glass system a suitable choice for high-energy ionizing radiation attenuation.

Summary: The study prepared a set of glasses composed of seven samples using a fast cooling mechanism. By varying the molar ratio of B2O3 and P2O5, three different types of oxide glasses were obtained. A shift from borate to phosphate glass resulted in an increase in various properties, and phosphate-rich glasses exhibited comparable shielding ability to standard glass samples.

Summary: Neodymium doped borophosphate glasses were synthesized and their luminescence properties were investigated. The participation of Nd3+ in the glass structure was confirmed by the increase in density and decrease in molar volume with increasing concentration of Nd2O3. Fourier transform infrared spectroscopy identified various structural units due to B2O3, P2O5, and PbO.

Summary: The application of solid-state high-resolution NMR spectroscopy in the structural investigation of chalcogenide glasses faces challenges due to the low abundance of certain nuclides, slow relaxation rates, and line broadening effects. However, these challenges can be overcome with 2D isotropic-anisotropic correlation NMR experiments, especially when combined with high magnetic field and CPMG echo train acquisition. These experiments have proved useful in deciphering structural characteristics and molecular dynamics in chalcogenide glasses, paving the way for future applications in addressing complex structural correlations and distributions.

Summary: The optical characteristics of Dy3+-doped phosphate and borophosphate glasses with different divalent network modifiers are investigated. The spectroscopic analysis shows the presence of four typical Dy3+ emission bands in the yellow, blue, and red regions of the spectrum. The fluorescence lifetimes are correlated to the ionic field strength of the network modifiers, with Mg2+ and Zn2+ containing glasses having the longest lifetimes. The yellow to blue emission intensity ratio indicates the coordination environment of Dy3+ ions in the glassy host network.
