Abstract:
Biomimetic mineralization of nanocalcium phosphate (CaP) on metal oxide surfaces has gained great interest because of their relevance to osseointegration performance of implant materials. However, precisely controlling the nucleation behavior of mineralized nano-CaP on metal oxide at selective sites still remains a challenge. Here, we demonstrate a phenomenon on facet-specific mineralization on anatase TiO2 polyhedral microcrystals organized by two facets of {101} and {001} in complete cell culture medium: nano-CaP covers up {101} facets, while there are a few on {001} facets. The comparative experimental results indicate that the preadsorbed fetal bovine serum (FBS) protein on {001} facets might play a barrier role in preventing sequential nucleation of nano-CaP. This work thus provides insight into the understanding of mineralization on metal oxides, and a way to control the mineralization.

Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
02:58Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
