Hard x rays induce atomic dynamics in oxide glasses at doses low enough that the average structure is unchanged. X-ray photon correlation spectroscopy used here to study this effect a series of alkali borate characterized by different network connectivity. The product x-ray dose rate per atom and decay time density function sample-dependent parameter with dimensions an energy: It varies between...

Bioactive glasses (BGs) are especially useful materials in soft and bone tissue engineering even dentistry. They can be the solution to many medical problems, they have a huge role healing processes of fractures. Interestingly, also promote skin regeneration wound healing. able attach tissues form an apatite layer which further initiates biomineralization process. The formed intermediate makes ...

Abstract Barium titanium borate glasses doped with ytterbium ions were fabricated via standard melt quenching technique. The building structure of the glass matrices ascendant ratios studied using Raman and FTIR spectroscopies. UV–Vis–NIR optical absorption spectra investigated used to calculate bandgaps, Urbach energies, refractive indices, metallization criterion, basicity, dispersion paramet...
