Dynamic magnetic fields transform pivoting H₂SiO₃ particles to hollow microspheres with nanofibrous interior. [PDF]

Nat Commun
Reorganizing the internal structures of hollow microspheres after shell sealing, without damaging the shell, remains a major challenge. Here, we show a dynamic magnetic field fluxes stirring (DMFFS) technology that can transform H2SiO3 particle to a ...

Preparation of hollow hydroxyapatite microspheres

Journal of Materials Science: Materials in Medicine, 2006
The preparation of hollow hydroxyapatite (HA) microspheres as potential drug-delivery vehicles was investigated. A lithium-calcium-borate (10Li(2)O-15CaO-75B(2)O(3)) (mol%) glass, made by fusing the components at 1100 degrees C for 1 h, was ground to a powder and passed through a flame at approximately 1400 degrees Celsius to spheroidize the particles.
