Mesoporous Bioactive Glass Nanoparticles in the SiO₂-P₂O₅-CaO-MO (M=Mg, Zn) System: Synthesis and Properties [PDF]

Journal of Functional Biomaterials, 2022
Mesoporous bioactive glass nanoparticles (MBGNs) are widely recognized for their ability to bond to hard tissue, while the ions released from the BG structure enhance specific cellular pathways. In this study, the SiO2-P2O5-CaO-MgO-ZnO system was used to

Thermal stability of porous sol-gel phosphosilicates and their surface area stabilisation by lanthanum addition [PDF]

Materials Letters, 2016
The thermal stability of porous sol-gel phosphosilicates was studied by comparing the textural features upon calcination between 400 and 550 °C. A significant loss of surface area and pore volume were observed; the first is due to thermal coarsening of the nanoparticles, and the pore volume reduction was ascribed to sintering of the most external ...

Muon spin relaxation study of phosphosilicate gels

Solid State Ionics, 2020
Abstract Muon dynamics in phosphosilicate proton conductors P2O5-SiO2 with a composition 30 mol% phosphorus oxide (30P) have been studied as a function of temperature using muon spin relaxation. For materials heat treated at 300 °C the muons implant at sites close to P-OH groups associated with water molecules.
