WebDec 7, 2006 · Bioglass 45S5, the prototype of bioactive melt-quenched silicate glasses, was modeled by means of Car−Parrinello molecular dynamics (CPMD) simulations. Although long-range structural properties cannot be modeled by using this ab initio approach, the accuracy of CPMD simulations is exploited here to provide insight into the short-range … WebApr 12, 2024 · Bismuth is an essential component in the creation of a radiation shielding material that can successfully replace lead. As compared to lead-silicate-based glass, silicate-based glass that has had bismuth oxide (Bi 2 O 3) added to it produces a material with a greater density and demonstrates improved shielding capabilities [7,8].
