SILICATE 3 (image) Rice University Share Print E-Mail Caption Rice University materials scientists synthesized spherical, porous nanoparticles of calcium and silicate, formed films and pellets and tested their toughness under pressure from a nanoindenter. They found films made of larger particles approaching 500 nanometers were much tougher and the films and pellets less prone to cracking under pressure. At right, small particles are deformed after nanoindentation.
