Europium (Eu)-doped fluorapatite (FA) nanorods have a biocompatibility similar to that of hydroxyapatite (HA) for use as cell imaging biomaterials due to their luminescent property. Here, we discuss the new application of europium-doped fluorapatite (Eu-FA) nanorods as an anticancer drug carrier. The Eu-FA nanorods were prepared by using a hydrothermal method. The morphology, crystal structure,...

Apatite ore from Lao Cai province (Vietnam) has large reserves and low cost which was purified by a simple chemical method. one were characterized the molecular structure, phase component, specific surface area, element morphology IR, XRD, BET, EDX, SEM methods. The IR result shows both materials have functional groups of fluorapatite such as PO43- F-. XDR EDX confirm that main component is flu...

In this study, calcium phosphate nanoparticles with two phases, fluorapatite (FA; Ca(10)(PO(4))(6)F(2)) and hydroxyapatite (HA; Ca(10)(PO(4))(6)(OH)(2)), were prepared using the solgel method. Ethyl phosphate, hydrated calcium nitrate, and ammonium fluoride were used, respectively, as P, Ca, and F precursors with a Ca:P ratio of 1:72. Powders obtained from the sol-gel process were studied after...

Preliminary studies of the wear of fluorapatite single crystals subjected to sliding neglected the possible influence of crystallographic direction on the frictional behavior and surface failure of the basal plane.1-3 In these studies, possible anisotropic effects were considered to contribute to the experimental error in the analysis of the data. Buckley4 has observed that friction coefficient...

Historically, the study of the wear of hard dental tissues in modern man has been limited to clinical observation of physiologic and pathologic conditions that lead to wear, and to attempts to duplicate the effects of hygienic procedures such as the use of toothbrush and dentifrice on hard dental tissues in the laboratory. However, several fundamental investigations have been reported in which ...
