Preparation of hollow hydroxyapatite microspheres

open access: yesJournal 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.

Multi-shelled CeO2 hollow microspheres as superior photocatalysts for water oxidation [PDF]

open access: yes, 2014
A general self-templating method is introduced to construct triple-shelled CeO2 hollow microspheres, which are composed of tiny CeO2 nanoparticles. When the triple-shelled CeO2 hollow microspheres are used as photocatalysts for direct water oxidation ...
