A nano-porous alumina membrane (NPAM), which is a typical porous material formed by the anodic oxidation of aluminum, has a regular honeycombed structure with nanometer to sub-micrometer pores [22-26].
The NPAM possesses high shape stability, large surface area due to the nano-porous structure, and high transmittance in the UV-visible light region based on the large band gap of alumina of Eg ~ 8.5 eV [27,28].
The pore diameter of ~200 nm and a through-hole structure without lateral crossovers between pores were confirmed for the NPAM by field emission-scanning electron microscope (FE-SEM) observations (Figure 2).

Chemistry potential difference(concentration difference) was an important influence and was a main driving force extracting process.
The cause was that driving force of extracting process enhanced and the amount of saturation level increased difference as the increase of chemistry potential and the solvent.
Chemistry potential difference was obvious for extract rate.
Similarity, the solute and solvent were resembled with each other in structure; compatibility, the solute and the solvent was soluble each other.
At the same time, the penetrating power of water weakened through cell structure owing to the decrease of water.

The oxidation in the studied electrolyte results in the formation of oxide films on the alloy surface that have a two-layer structure [20].
Their advantages over one-layer films are the availability of the highly developed structure that provides a good cohesion of the bone tissue with the implant surface [21].

The XRD pattern of ZFO also confirms the spinel structure of the ZFO with face-centered cubic (FCC) formation.
On other hand, CIP has two pKa values, namely 6.16 and 8.23, which mean the zwitterionic molecular structure of CIP dominate within this range.

By means of calcinations, carried out at 550°C for 2h, the hydroxyl-precursor decomposes into pure and partially crystalline cassiterite (rutile-like structure), as confirmed by XRD analysis.
It was very surprising to find nanoparticles with crystalline phase very similar to rutile; indeed, in pure or ion-added titania, the rutile structure is always strictly related to grain coarsening.
