ABSTRACT
Monodisperse uniform zirconium-titanium mixed oxide microspheres (approximately 3 microm) with different zirconium/titanium ratios are easily synthesized (using Zr(acac)(4) and Ti(OBu)(4) as precursors) by a sol-gel method and have been characterized for their enrichment of phosphopeptides from standard protein alpha-casein.

ABSTRACT
Monodispersed mesoporous silica spheres (MMSS) with periodical large-pore size (up to 200 A) and uniform particle size (1-1.7 mum) have successfully been synthesized by utilizing a new kind of surfactant, and they also demonstrated great potential application in HPLC.
