To investigate the reason for the blood compatibility of titanium oxide, we synthesized titanium oxide films with different structures and composition using plasma processes.
It was found that the crystalline structure, the oxygen atom content, and the doping element can all affect the interaction between the Ti-O films and blood.
By means of plasma and light chemistry processes some anticoagulant molecules can be immobilized on polymer surfaces and play a role in increasing blood compatibility.

The morphology, pore structure and particle size, which strongly affect the functionality of the materials, play decisive roles in their industrial applications.
As the NaOH/TEOS molar ratio increases, the corresponding intensities for the reflections become more pronounced with sharpened peaks, implying the enhancement of regularity of the hexaganol structure with respect to the increasing basicity.

It can be observed that the product possesses a tubular structure with the length of 500-800 nm and the outer diameter of about 100 nm.
It is found that the XRD patterns of two products are almost same, implying little influence of Cu loaded on the crystal structure of potassium hexaniobate nanotubes.

Fig. 1 is a cross-sectional view of CdS-TNT sample showing that the film is composed of well-aligned nanotubes of about 300nm in length which grow vertically from the Ti substrate, which reveals a regularly arranged pore structure of the film.
And the inserted part of Fig. 1 is a typical SEM image of CdS-TNT sample, which reveals the well ordered pores structure of the film.

The phenomenon of sedimentation and diffusion of dust depend on the combination of many factors: specific gravity, direction and speed of dust particles, the structure and shape of the surface of the particles, humidity, electrical state and temperature of the ambient air, its density, motion, electric state, etc.[3].

It was reported that graphene is a suitable electrode for supercapacitor storage system since it has a porous structure, high surface area, high electrical conductivity, as well as good wetability [2,3].
The GO material can be reduced to graphene-like sheets by removing its oxygen-containing groups and recovery its conjugated structure [5].
