Nanomaterials with many kinds of morphologies and compositions have been
extensively investigated, and display various kinds of functionality in areas such as electronic
structure, optical effects, spin dynamics, and gas sensing.
Because of advanced characterization and new fabrication techniques, nanomaterials are now central to multiple disciplines, including materials science, chemistry, physics, engineering and medicine.

Abstract.
The products exhibited anatase phase structure, mesoporosity, and interesting surface compositions with three oxygen species and two titanium species.
Phase structure.
The results indicate that Eu3+/TiO2 show pure anatase phase structure under the current preparation conditions.
The selected area electron diffraction (SAED) patterns further confirm the anatase structure of as-prepared pure TiO2 and Eu3+/TiO2 composites (Inserts in Fig. 5).

In the same way, some of the Al3+ in the octahedral layer can be replaced by Mg2+, without disturbing the crystal structure.
In addition, an analysis was carried out to observe changes in basal spacing of bentonite structures after pillarization and impregnation.
The pore size distributions of zirconia pillared bentonite and nickel impregnated bentonite displayed dominance of mesoporous pore structure.
The parallel lines showing the layered structure of the bentonite became clearer after the pillarization stage with ZrO2 (figure 6 b).

Fluoridated hydroxyapatite (FHA) has the same crystal structures with HA, while hydroxyl groups were totally or partially substituted by fluorine.
The more compact structure has been recognized to be effective in reducing the solubility of the materials[3-4].
The effect of content of fluorine ion on the phase and structure of the apatite powders were investigated.
The XRD patterns of the synthesized powders reveal an apatite structure with broadened maxima as displayed in Fig. 3.
