The aim of this work is to investigate the effect of lowering the phosphate content, from 27 to 20mol%, in calcium-phosphate invert glass/glass-ceramic containing magnesia and niobia (MgO-CaO-P2O5-Nb2O5) on the structure and dissolution properties. According to 31P solid-state nuclear magnetic resonance (NMR) and Raman spectroscopies, glass containing 20mol% of P2O5 was exclusively composed of orthophosphate...
Porous titanium oxide nanocups were synthesized via a 550°C thermal treatment of hemispherical cup-shaped composite particles prepared by electrospraying a nitromethane solution of titanium tetraisopropoxide and polymethylmethacrylate (PMMA) polymer. During the calcination process, as-electrosprayed cup-like PMMA–TiO 2 composites were converted into miniaturized TiO 2 nanocups without...
