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: The study focuses on ion transport in network glasses and uses a statistical mechanical approach to predict the distribution of energies of mobile alkali ions in alkali borophosphate glasses. The mapping of ion dynamics onto a network of local conductances derived from jump rates allows for the calculation of DC conductivities without extensive Monte Carlo simulations, showing good agreement with experimental data.

Summary: The structural changes of borophosphate glasses with different compositions were investigated using NMR, Raman spectroscopy, and HPLC. The replacement of P2O5 by B2O3 led to the formation of tetrahedral borate sites linked to four phosphate anions and a decrease in the average size of phosphate anions. Further increases in B2O3 content resulted in the replacement of phosphate units linked to the boron tetrahedra by borate units. The changes in the glass transition temperature and molar volume of the glasses can be explained by considering the number and types of bridging oxygens per glass former.

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: A major challenge in modeling ionically conducting glasses is to understand how different chemical compositions and structures affect ionic transport quantities. Theoretical approaches have been developed to explain the variations of both network former unit concentrations and activation energies with glass composition, showing good agreement with experimental data for alkali borophosphate glasses.

Summary: This study investigates the structure and mechanical properties of lithium borophosphate glasses. The addition of boron in the phosphate network increases the network rigidity and enhances properties such as density, hardness, and glass transition temperature. However, it also decreases Poisson's ratio and crack initiation resistance. The presence of trigonal boron units in high-B2O3 glasses significantly affects atomic packing density and Vickers hardness.

Summary: The study synthesized lithium-zinc-borophosphate glasses with different Nd2O3 doping levels and investigated their physical and optical properties. The results showed that Nd2O3 doping can decrease the half value layer of the glass, increasing its resistance to gamma rays.

Summary: The effects of P2O5 substitution on the coordination structure of a Bi3+ in Bi2O3-B2O3 glasses were investigated. The substitution of P2O5 with B2O3 was found to be effective for forming the solvation shell, resulting in weak ligand field around Bi3+.

Summary: The addition of MgO to aluminosilicate glasses has a dual role as glass network modifier/charge compensator and network former, depending strongly on the composition of other oxides in the glass. The non-linear evolution of the isokom annealing temperature upon increasing Al2O3 content in the peraluminous regime can be rationalized in terms of the combined effects of short-range connectivity and medium-range ring size distribution.

Summary: The effect of adding niobia to borosilicate glasses was studied. It was found that niobium can integrate into the glass structure, causing changes in thermal and structural properties, and also reducing the viscosity of the glass melt.

Summary: In this study, a gel polymer electrolyte (GPE) system blended with poly(methyl methacrylate) (PMMA) and polylactic acid (PLA) doped with lithium bis(oxalato) borate (LiBOB) was incorporated with different compositions of 1-ethyl-3-methylimidazolium chloride (EMIM(Cl)) to create a lithium-ion battery for electronic devices. Fourier transform infrared (FTIR) spectroscopy and x-ray diffraction were used to determine the free ions and their complexation with the doped polymer blend. The inclusion of EMIM(Cl) was confirmed by the appearance of a new peak in the FTIR analysis. The addition of ionic liquid enhanced the dissociation of Li+ cation and facilitated ion transport, resulting in optimum ionic conductivity of GPE samples with 18 wt.% of EMIM(Cl). The findings demonstrate the potential of the GPE-based PMMA/PLA-LiBOB doped with EMIM(Cl) as an energy storage device, particularly for Li+ batteries.
